In a grinding wheel, the abrasive grains are held in place by a bond matrix (hence the name bonded abrasives) and are separated by pores to create a sharp instrument with many cutting edges.

Porosity, or the voids between abrasive grains and their bond, aids in the grinding process.

The grinding wheel’s abrasive grains penetrate the material being smoothed, chipping away the imperfect outer layer.

The grinding process dulls the abrasive grains’ cutting edges. In addition, the heat produced by the heightened friction either causes the abrasive grain to crack, exposing fresh cutting edges, or begins to deteriorate the binding bridges, causing the abrasive grains to become more loosely packed.

During regular vitrified grinding, the wheel must be dressed with a dressing tool (you can read more about dressing tools here). Changing the abrasive qualities, bond type, and structure of a grinding wheel allows for the creation of wheels with a wide range of grinding characteristics.

Discs are commonly used in a variety of industries, and there are many different types of discs for different purposes, such as cutting discs, grinding discs, polishing discs, and sanding discs. Cutting discs should not be used for any grinding or cutting purposes.

Discs made of metal and those made of stone must be clearly marked as such. When cutting or grinding, use only the disc made specifically for that purpose.

While stone cutting discs are effective at slicing through metal, the process causes the discs to shatter and splinter, endangering not only the user but also anything that happens to be in the way.

Keeping all this in mind, it should go without saying that whenever you are grinding or cutting, you should always hold the blade so that the cutting edge points away from you.

You’ve probably noticed the guard that covers half the disc in an angle grinder before. With a little wiggle room, the guard can be positioned between your hands and the disc regardless of how you’re holding the grinder.

Now that we know that the guard is always there to protect us and that we should never use a disc or attachment on a material other than the one it was made for, we can move on to learning about the different kinds of attachments out there.

An angle grinder can be used to cut, grind, or polish with relative ease. This handy tool, which comes in both portable and permanent varieties, works equally well on everything from glass to metal. Matching the right angle grinder with the right disc is essential. In terms of velocity, security, strength, and dimension, you can pick from a wide variety of possibilities. The following are examples of common types of angle grinder discs:

What Angle Grinder Wheel Is Best for Cutting Metal?

For use with angle grinders, the word “arbour” refers to a 7/8″ cut-off wheel.

Arbour wheel cutter 7/8″

To accommodate 7/8″ arbour cutoff wheels, angle grinders with a 5/8″-11 threaded arbour have a special shoulder.

The cutoff wheel can be used to make precise metal cuts. It can be used to eliminate welds, trim down bolts, and cut tiny pieces from sheet or plate metal. Edge of the wheel, not the back or the front, is what should be used. Using either side of a cutoff wheel weakens it because the fibres that hold it together are exposed on both sides.

Cutting wheels are significantly thinner than grinding wheels. Use materials no thicker than an eighth of an inch (about 0.045″). Wheel for grinding, about half as thick as a quarter A metal’s thinness and the fact that they only cut along the edge make it easy to cut through it quickly.

Metal cutting is best accomplished with the thinnest angle grinder wheels. However, the danger heightens as wheel thickness rises. Thinner cutting wheels can easily split apart when bent. Working at a workstation in an ergonomic posture with the workpiece in the right location is ideal for using a miniature cutoff wheel. Doing unpleasant work under a car? If you want a “Wheel for cutting that is slightly more solid and won’t break if you lose your footing or your grip,” a 1/8-inch ratchet is what you need.

Which Angle Grinders Wheel Is the Most Dangerous?

The cutoff wheel has many applications, but its low profile makes it dangerous to use. If you twitch, lose your balance, or twist the grinder in any way, you will shatter this grinding wheel. The explosions from the missiles could cause a variety of injuries, including broken noses, harmed hands, injured onlookers, etc. Your face should be kept well away from the axis of rotation of the wheel at all times.

Only a small number of cutoff wheels have been broken over the course of our many years of fabrication, but hundreds of standard 1/4″ grinding wheels have. Injuries among fabricators are commonplace due to improper use of cutoff wheels and a lack of safety gear. One of our fingers was severely damaged when a broken cutoff wheel slammed into it. The man now has a beautiful scar and some abrasive debris embedded under his nail. Put on all your safety gear and do your best to mount the cutoff wheel on the angle grinder.

Wearing safety goggles, a face mask, a grinder guard, and thick gloves while turning this wheel is mandatory, as is working in complete isolation from any other people. You shouldn’t use a cutoff wheel if you don’t have something to hold the material’s ends. The wheel could be broken if the dangling part squeezed it while it was turning. A chop saw is ideal for tasks like shortening lengths of tubing or angle iron.

Grit Discs

Using grit discs to grind metal or stone to a smooth finish is the most cost-effective option. Considering the disc is only about 6 mm thick, it’s likely that it won’t last very long before it needs to be replaced. When compared to other choices, however, they can cut at a much faster rate. Moreover, they weigh next to nothing, which is great news for anyone who needs to climb a ladder or work on an elevated surface.

The grit disc of an angle grinder is one of the more reasonably priced accessories available. In general, they are thinner than most other types of grinding discs, by about 6 mm. The most common materials to be shaped by these instruments are stone and metal. Comparatively, grit discs have many advantages. They can make precise cuts at high speeds. The compact size and light weight of a grit disc grinder makes it ideal for use on a ladder or other elevated work platform.

What Are the Other Materials in an Angle Grinder?

Diamond Discs

Diamond discs are a versatile cutting tool that can be used on a wide variety of materials. They are more commonly used for grinding and cutting because they are more efficient than grit discs. They don’t cost much, but could last a long time. When using diamond discs, the risk of getting hurt when the disc flies off the grinder is greatly reduced.

However, discs crafted from diamond are far superior to the one described. They’re used for the same purposes as grit discs, namely cutting and grinding, but they’re much more effective at doing so. This is because even the cheapest diamond discs available today can outlast grit discs and are significantly less expensive. Diamond discs have been shown to be safer to use than steel discs, which have a very low likelihood of coming off.

Wire Wheel

The best way to remove paint and corrosion and to polish raw metal is with a wire wheel. The object being worked on must be rigid, like metal, to avoid being damaged by the wire wheel. Furthermore, wire wheel discs come in a wide range of styles and sizes, allowing for even more applications. When cleaning metal, the twisted wire wheel is the most effective tool, while a cup brush is less so and will take more time to clean the surface.

In contrast to the wire wheel disc, which is used for polishing and removing rust and paint, the aforementioned discs are primarily employed for grinding and cutting. A wire wheel disc is the best tool for scraping paint and rust off metal. It’s important to use caution when operating the wire wheel, as it can easily cause damage if used on something soft.

Wire wheels excel at removing paint and corrosion from a surface. Wire wheels’ superior scrubbing power is the result of their thick, twisted bristles. While straight, thin bristle brushes are easier on surfaces, they aren’t as efficient at removing paint or rust. Every single one of our angle grinders has twisted wire wheels installed. We only use extremely small, straight-bristled drill bits and wire wheels for our die grinders.

Angle Grinder Twisted Strand Wire Wheel

This wheel has thick, twisted bristles, making it aggressive. This wire wheel is ideal for scraping away stubborn paint or rust.

There is no difference in the speed at which things can and do fly off this wheel compared to any of the others; the wires sometimes come away with enough force to stick in your flesh. No matter how bad it seems, you should still keep your eyes covered. It’s important to use high-quality wire wheels with your angle grinder. Our experience with Harbor Freight wire wheels has been that they wear out quickly and litter your workspace with sharp wire ends. It’s unbearably unpleasant, and the filaments can easily pierce skin, so it could even be dangerous (and certainly eyeballs).

Keep in mind that wire wheels come in a number of different styles. The most effective wheel is a twisted wire wheel, while the cup brush variety should be avoided at all costs.

Wood Discs

These discs were developed specifically for use on a wide variety of wood types. However, its versatility may be limited by discs designed exclusively for wood. Discs that work well on both wood and metal will extend the life of your grinding tool. This is the method to use if a nail needs to be extracted from the wood. Arbortech, the strongest and longest-lasting wood disc, is highly recommended.

As their name suggests, these discs are ideal for making clean cuts through wood. However, the versatility of a disc is diminished if you restrict it to wood cutting. Discs that can cut through steel are a good investment in case a nail does manage to penetrate your wood. There are many different kinds of wood discs, but the one with the best cutting performance is the arbour tech.

When selecting discs for an angle grinder, keep in mind both the material you’ll be working with and the final result you’re hoping to achieve. Options abound to fulfil any requirement.

Abrasive Discs/Pads and Sanding Discs/Pads:

Similar to traditional sandpaper, these are sold in packs of replacement sheets, but unlike traditional sandpaper, they can be attached to a soft pad or base and then to the grinder or sander. Depending on how rough you like your paper, you can choose from 40 grit all the way up to 400 grit. You can simply remove the worn paper and replace it with a new sheet.

Keep a grinder and some extra flap sanding discs on hand. For fine detailed grinding when a standard grinding disc would be too abrasive, these are ideal. They are typically used for sanding and cleaning surfaces (mostly metal). Since they have different grits, polishing from coarse to fine may produce the desired effect.

Polishing pads, like the aforementioned attachments, are used by simply screwing them into the grinder’s threaded portion and tightening them with a spanner. The polishing head or cloth should then be fastened to the pad. These, too, are easily interchangeable. If you’re trying to smooth out or polish something with some heft, these pads and coatings are your best bet. To restore lustre to paint and other delicate surfaces, you can use a polisher, also known as a mop. Working on delicate surfaces sometimes calls for a larger 230mm grinder that runs at slower speeds.

Bonds

For the wheel to function as a cutter, the abrasive must be able to access the proper bond. The bond ensures the abrasive grains stay together, increasing their efficiency. In order for new, sharp abrasive grains to be exposed as the old ones wear down and are flushed away, the connection must break down.

There are three common types of bonds used in conventional grinding wheels. The motion of the grinding wheel could be affected in different ways depending on the type. The bond type to use depends on the operating speed of the wheel, the grinding operation, the required accuracy, and the material to be ground.

Most grinding wheels are constructed out of vitrified bonds, a mixture of specific clays. When heated to the high temperatures required to create grinding wheels, the clays and abrasive grit used in them fuse together into a molten glass state. While the glass is still cooling, it forms a bridge between the grains, which keeps them from moving around too much while they are being ground.

Grinding wheels are made with vitrified bonds that are extremely strong and impermeable. They can quickly and precisely reduce inventory by grinding to exact specifications. They can withstand anything nature can throw at them, including moisture, oil, and temperature swings.

In spite of their sturdiness, vitrified links tend to break easily. They’re ground into a fine powder by the intense pressure of the grinder.

Some types of bonding require organic materials. These bonds are weakened by the high temperatures produced by grinding. The resinoid bond, an artificial organic bond, is widely used. When high cutting speeds are required for stock removal, resinoid-bonded wheels are a reliable option. Metalworking (for grinding wheels), manufacturing (in billet shops), and even woodworking make extensive use of high-speed grinders (for saw sharpening and gumming).

One such organic link is the rubber industry. Using wheels bonded with rubber reduces the jolt caused by grinding. Rubber bonding is frequently used due to the high quality finish it provides on ball and roller bearing races, two common wheel applications. They are also frequently used in cutoff wheels, where the removal of burrs and burns is of utmost importance.

A grinding wheel’s grade can be thought of as an indicator of the quality of the bond. A hard bond is one in which the gaps between the abrasive grains are extremely robust and successfully resist the grinding forces trying to pry the grains apart. When the grains can be shaken loose with minimal effort, we say that the wheel has a gentle grade. If there’s a lot of bond inside a wheel, it’ll be very hard.

When wheel life is crucial, when high horsepower is present, or when there is a need for a small contact patch, wheels with a higher hardness grade are employed. When working with tough materials like tool steels and carbides, it is best to use wheels of the soft grade variety because they are ideal for fast stock removal and tasks requiring large contact areas.

Wheel Shapes

It’s possible to come across numerous variations of the wheel. Most people picture a perfectly round wheel when they think of a grinding wheel. The grinding face, the part of the wheel that actually makes contact with the work, is visible from the outside of a straight wheel. Recessed wheels are a common modification of the straight wheel design, so called because of the depression cut into the centre of the wheel to allow for mounting on a machine spindle flange.

For some wheels, the cutting edge is situated on the outer rim. Common names for these wheels include in-cylinder wheels, cup wheels, and dish wheels. The bonded abrasive components of a side grinding wheel can take many forms, allowing for either continuous or intermittent use. These products fall under the category of segments. Wheels with cutting faces on the sides are commonly used for grinding the teeth of cutting tools and other hard-to-reach areas.

Often referred to as simply “mounted wheels,” these miniature grinding wheels feature a special design and are fastened to a steel mandril. They’re useful for a wide variety of internal grinding jobs, from rough to fine.

Is It Ok to Tie All the Parts of an Angle Grinder?

Several factors must be considered in order to settle on the best grinding wheel. What will be the ground surface is the first consideration. As a result, this determines the type of abrasive that should be used in the wheel. For instance, aluminium oxide or zirconia alumina is the ideal material to use when grinding steels and steel alloys. You should use a silicon carbide abrasive for grinding cast iron, non-ferrous metals, and non-metallics.

If you’re dealing with tough but delicate materials, you should switch to a finer grit wheel. Abrasive grains have a hard time penetrating hard materials, quickly wearing them down. Because of this, abrasive grains are more likely to separate as they dull, revealing fresh, sharp cutting edges thanks to the combination of finer grit and softer grade. however, wheels with a coarse grit and hard grade are recommended for soft, ductile, and easily penetrable materials.

The quantity of stock that needs to be liquidated is another factor to consider. Coarser grits can cut deeper into materials and remove more stock more quickly because of this. If the work material is tough to get through, however, a wheel with a finer grit will do the job more quickly. This is due to the increased availability of convenient cutting areas.

Cutting is accelerated with vitrified-bonded wheels. Use resin, rubber, or shellac bonding if only a small amount of material needs to be removed, or if there are more stringent finish requirements.

Another factor to think about when choosing a bond is the wheel’s operating speed. When travelling at speeds of 6,000 feet per minute or less on paved roads, vitrified wheels are commonly used. At higher velocities, the vitrified link could potentially break down. Common organic bond wheels have a surface area turnover rate of between 6,000 and 9,000 square feet per minute. Working at higher speeds often necessitates the use of high-speed grinding wheels.

However, you shouldn’t exceed the speeds displayed on the wheel or blotter. This could be written in rpm or sfm.

Next, you should consider the area of contact between the grinding wheel and the workpiece. Greater surface area contact is achieved with a coarser grit, softer grade wheel. Thus, the cutting motion is kept unencumbered and cool despite the increased load resulting from the increased cutting surface area. Increased unit pressure from grinding on smaller contact surfaces necessitates wheels with finer grits and harder grades.

Next, consider how severe the grinding will be. The effort required to bring and keep the grinding wheel in contact with the workpiece. When grinding steel and steel alloys, certain abrasives are built to withstand the high temperatures and pressures.

Horsepower is another consideration for the grinding machine. Wheels of a higher grade should be used on machines with more horsepower. A lower-grade wheel should be used if the diameter of the wheel is smaller than the amount of horsepower available. Higher quality wheels are required when the horsepower-to-wheel-diameter ratio is greater.

How Should I Handle My Angle Grinder?

When mounting and using a grinding wheel, it is important to keep safety in mind.

Always keep them where they won’t be at risk of being scratched or dented. The bonding in some wheels can be weakened by extremes in temperature and humidity, so it’s important to keep the storage area as consistent as possible.

To ensure that no wheels were damaged during shipping, it is important to inspect all new wheels immediately after they have been removed from their packaging. Any previously used wheels that are returned to the storage facility should also be inspected for quality.

Dropping or bumping a wheel can easily cause it to break or get damaged. You can’t roll a wheel into work; you have to carry it. If the wheel is too heavy to carry safely in one’s hands, one should use a hand truck, waggon, or forklift truck with padding.

To ensure that a vitrified wheel is safe to use, ANSI B7.1 recommends running a ring test on it before installing it. The ring test is used to identify defective wheels. Don’t ever use a damaged wheel.

If you don’t want to ruin the grinding wheel, don’t crank up the machine’s spindle rpm higher than the manufacturer suggests.

Always go for wheels that have a snug but not overly restrictive fit in terms of the diameter of the spindle hole. The central void should never be repaired! Flanges should be paired and at least a third the size of the wheel’s diameter. Flanges must have perfectly smooth bearing surfaces that are free of burrs and other debris to function properly.

Tighten the spindle nut until the wheel is snug but not stripped. Before securing the directional wheel to the spindle, check that its arrow points in the direction of rotation.

Make sure all covers are fastened and wheel guards are installed before starting the machine. Before beginning to grind, power on the machine, check that the wheel is securely fastened, and position the safety shields so that the machine can run unimpeded for at least a minute.

For grinding, only the smooth side of a wheel should be used. When grinding, always make sure to use the flat side of a cylinder, cup, or segmented wheel. Don’t slam into each other or try to make grinding contact; instead, apply gentle, even pressure. Never grind so long that the motor significantly slows down or the work gets too hot. A machine’s ampmeter is a good indicator of whether or not it is functioning properly.

In the event that a wheel fails while you are using the machine, make sure that none of the shields or covers have been damaged. Check the flanges, spindle, and mounting nuts to ensure there is no bending, springing, or other damage.

How Does an Angle Grinder Work?

The grinding wheel is one component of a larger designed system that also includes the machine tool, the work material, and the operational parameters. Each facet is intertwined with the others. That’s why any company that gives a hoot about grinding will invest in a grinding wheel that plays nice with the rest of the machinery and tools in the process.

What Are Superabrasives?

The superabrasives subset of bonded abrasives is designed specifically for grinding the hardest substances.

Since some cutting tool materials, such as carbides, high-speed steels, PCD, PCBN, and ceramics, can be nearly as hard as ordinary abrasives, sharpening them requires a special category of abrasives, namely diamond and the CBN, the super abrasives.

These materials may be extremely hard, but they are more expensive than typical abrasives (silicon carbide and aluminium oxide). That’s why you won’t find any similarities between regular and super abrasive grinding wheels in terms of construction. The abrasive material in a super abrasive wheel is concentrated at the wheel’s cutting edge, while the rest of the wheel is made of a core substance that provides structural support and aids in the grinding process.

When compared to standard wheels, superabrasive options have the same grit range (typically 46 through 2,000 grit). Depending on your needs, you can choose between a range of concentrations (how much diamond is in the bond) and quality levels (how much diamond is in the wheel).

There are four distinct bonds available for extremely abrasive wheels. Resinoid bond wheels offer unrivalled cutting speed and temperature. When put through the grinding process, they are perfect for honing multi-toothed cutting tools and reamers. Since it’s the most common and versatile choice, resin bond is often called the “workhorse” bond. Vitrified bond wheels have unmatched cutting speed and wear resistance. They are commonly used in factories that produce goods in large quantities. Metal bond wheels can be used to grind and slice non-metallic materials such as stone, reinforced polymers, and semiconductor materials. Single-layer plated wheels are used to rapidly remove stock and produce a complex shape.

Conclusion

Grinding wheels are sharp instruments with many cutting edges made from abrasive grains that are held together by a bond matrix and separated by pores. Changing the abrasive qualities, bond type, and structure of a grinding wheel allows for the creation of wheels with a wide range of grinding characteristics, and the wheel must be dressed with a dressing tool during regular vitrified grinding. Discs serve a wide range of purposes and are widely used across many industries. When cutting or grinding, always use the disc designed for the task at hand, and never attempt to adapt a disc or attachment to work with a material that it wasn’t intended to. No matter how you hold an angle grinder, the guard that covers half the disc will always be between your hands and the disc.

Whether you need to cut, grind, or polish metal, an angle grinder is a useful tool to have around. Angle grinders can be either portable or stationary, and the right disc must be used with the right grinder. 7/8″ cut-off wheels, 5/8″-11 threaded arbour cutoff wheels, and 1/8″ ratchet wheels are all typical disc sizes for angle grinders. Thinner angle grinder wheels are better for cutting metal, but they pose more of a threat. Cutoff wheels are useful in a wide variety of situations, but they can be dangerous due to their low profile.

Wearing protective gear is essential when using cutting wheels, a common hazard in the fabrication industry. Despite being thinner than most other types of grinding discs, grit discs are the most cost-effective option for grinding metal or stone to a smooth finish. Diamond discs are superior to grit discs in cutting efficiency and versatility, and can be used on a wide variety of materials. If you’re using a diamond disc, you won’t get hurt as badly if the disc flies off the grinder. When compared to steel discs, diamond discs perform more efficiently and are safer to use when cutting or grinding.

Wire wheels, with their dense, twisted bristles, are the ideal device for stripping away paint and corrosion from a surface. The best tool for removing old paint or rust is a twisted strand wire wheel for an angle grinder.

You should only use high-quality wire wheels with your angle grinder. There are several different types of wire wheels, but the most efficient type is a twisted wire wheel. While wood discs excel at making clean cuts in wood, their applicability beyond this material may be limited. When used in conjunction with a soft pad or base and a grinder or sander, the Arbortech disc is the strongest and longest-lasting wood disc available. Using abrasive discs/pads and sanding discs/pads, you can take off the old paper and put in the new.

When a standard grinding disc would be too abrasive, keep a grinder and some spare flap sanding discs on hand for the fine, detailed grinding you’ll need. Restoring shine to fragile surfaces is as easy as using a polisher, also known as a mop, and a variety of polishing pads and coatings. Vitrified bonds, a combination of certain clays and abrasive grit, are used to create grinding wheels because they are so durable and impervious to moisture. They’re impervious to rain, oil, and extreme temperatures. However, the high grinding pressure can easily fracture vitrified links.

Resinoid bond is a synthetic organic bond used extensively in the metalworking, manufacturing, and woodworking industries. The elimination of burrs and burns is a top priority when using cutoff wheels, and rubber bonding is used in this context as well. The bond strength of a grinding wheel is indicated by its grade, with the softest grades being best for rapid stock removal and jobs with large contact areas. Wheels that are set back into the hub are a common deviation from the standard, straight wheel. The most critical parameters to consider are the stock quantity to be liquidated, the cutting speed, and the type of abrasive to be used in the wheel.

Since it is difficult for the abrasive grains to penetrate the tough material, a finer grit wheel will get the job done faster because there will be more readily accessible cutting areas. When only a small amount of material needs to be removed or when a higher level of finish is required, vitrified-bonded wheels are an excellent choice. Bond selection requires thinking about the grinding wheel’s operating speed, the grinding wheel’s contact area with the workpiece, and the grinding’s intended severity. It is recommended to use higher quality wheels on machines with more horsepower, and lower quality wheels on machines with a smaller diameter wheel than the horsepower available. New wheels should be inspected right after they are removed from their packaging, and the storage area should be kept in a consistent state.

Wheels are easily broken or damaged if dropped or bumped, so it is best to carry them carefully in one’s hands. A vitrified wheel must pass a ring test before it can be installed, as per ANSI B7.1. Do not use a wheel that has been damaged, increase the spindle speed beyond what is recommended by the machine’s manufacturer, and use wheels that fit tightly without being too restrictive. A wheel’s flanges should be paired and at least one-third the diameter of the wheel. Spindle nut should be tightened until wheel is secure but not stripped.

Make sure there is no bending, springing, or other damage to the flanges, spindle, or mounting nuts. Superabrasives are superior grinding tools because they can break down even the hardest materials. Carbides, high-speed steels, polycrystalline diamond bonded (PCD), polycrystallineBN (PCBN), and ceramics are just some of the cutting tool materials that can be sharpened using super abrasive grinding wheels. The cutting edge of the wheel is where the abrasive material is most concentrated, while the rest of the wheel is made of a core substance that provides structural support and aids in the grinding process. Super abrasive wheels can be bonded in one of four different ways: resin, vitrified, metal, or single-layer plating.

The cutting speed and temperature of resinoid bond wheels are unparalleled, while the cutting speed and wear resistance of vitrified bond wheels are unparalleled. Stone, reinforced polymers, and semiconductor materials are just a few of the non-metallic materials that metal bond wheels can be used to grind and slice.

FAQs About Metal

What Are Different Angle Grinder Discs Used For?

Usages. You can use cut-off discs for cutting metal bars, metal tubes and small pieces of metal sheets and plates. You can also cut out welds with them. For shortening the length of various bolts, it is also a good idea to use an angle grinder and a cut-off wheel.

Do All Angle Grinder Discs Fit?

Angle grinders discs are interchangeable, which means you can select the specific size of disc for your grinder and the specific type of disc for the type of material you are looking to cut or grind. There is a wide range of different types of discs available for an angle grinder.

How Do I Choose an Angle Grinder Disc?

The size of the disc should have a direct bearing on your choice of angle grinder. The two most common disc sizes are 4.5″ (115mm) and 9″ (230mm). Grinders with larger discs are particularly well suited to heavy-duty applications, whereas those with smaller discs are ideal for finer work.
