Right Angle Grinding Abrasives: Know Your Options

perators have choices when selecting an abrasives product to grind down welds or to perform beveling on a workpiece. Choices include grinding wheels, flap discs, or fiber discs. All three excel at removing large amounts of metal. But, what unique advantages can these abrasive products provide?

Let’s start with grinding wheels, the roughest and toughest of the three. They are created by combining resins, fillers, and grain together into a mix and forming the wheel using pressure, time and heat. Once cured, the wheels are extremely hard and can handle the most aggressive grinding applications.

Flap discs are made out of cloth backing and abrasive material. Most of the material used for flap discs can be also used for belts, quick-change discs, and other shaped products. The material is slit and cut into small pieces called flaps. These flaps are held in place by adhesive, pressed onto the backing plate, then cured to set the adhesive forming their shape. Flap discs primarily have two types of backing plates, fiberglass or plastic. Fiberglass is more rigid and less flexible than plastic. If the job is more demanding, fiberglass will be able to remove more material faster. Most plastic backing plates are trimmable to help increase the life and offer additional conformability. Both backing types for flap discs are available in Type 27 wheels which are used at angles from 0-to-15 degrees, and fiberglass backing is used in Type 29 wheels from 15-to-25 degrees.

Fiber discs are also made with abrasives, but the backing is vulcanized reinforced paper. They are strong enough to handle a resin-over-resin coating system, and they are also able to withstand heat generated during grinding.

Grinding wheels and flap discs do not require a back-up pad like their cousin, the fiber disc. Fiber discs require a back-up pad because their reinforced fiber backing alone is not strong enough to withstand the forces of grinding. All three products are available with a 5/8”-to-11″ backing plate or hub insert. The benefits of the 5/8”-to-11″ are easy on-and-off operation without the need for tools, which reduces the change out time.


Each product requires a great deal of care, including stock rotation, to ensure safe use. Fiber discs must be stored in proper conditions to prevent curl. If the environment has too much humidity, the backing will absorb the moisture, causing a sand-side in curl. Too little humidity and the backing becomes dry and starts to shrink, producing a sand-side out curl. The sand-side out curl will make it difficult to lock the fiber discs onto the back-up pad and the product could be too dry which may possibly result in breakage. The sand-side in curl will make the edges of the discs more easily able to snag the workpiece, leading to damage or operator injury.

Norton Quantum3 combo wheels provide substantially faster grinding for increased metal removal and longer wheel life, with less operator fatigue.

Grinding wheels also need to be stored properly. They should be kept in an area that is not exposed to high humidity or freezing temperatures and they should be kept away from areas that are vulnerable to water or other solvents, because these extremes can affect the bond of the wheel. Most wheels need to be stored in their original container. When the abrasive wheel is mounted on the grinder, it is best to have a holder that can help prevent the wheel from potential damage. If the grinder is dropped, placed on a surface with excessive force or is impacted by other objects, the holder helps protect the wheel from damage. Always inspect wheels before grinding and discard any wheel with cracks or damage.

Flap disc storage is recommended at 40-to-50 percent humidity and 60-to-80 degrees Fahrenheit. It is best to store flap discs in their original container and rotate stock as you would with grinding wheels and fiber discs. Inspect the discs before using and discard if any flaps are missing.

Using all three products requires proper personal protective equipment (PPE) and a clean work area free of bystanders and flammable material.


Grinding wheels are extremely tough, but damage can result when a wheel is dropped on a table or hard surface. Care should always be taken to prevent the wheel from becoming damaged, and if a wheel is compromised, it should not be used. By using a damaged wheel at 10,000 rpm, everyone in the room becomes susceptible to a potential accident waiting to happen.

It should also be noted that grinding wheels require more training than flap and fiber discs. A Type 27 grinding wheel requires a 30-degree angle while Types 28/29 require 0-to-15 degrees. Operators that use a Type 27 wheel too flat can increase the bevel, which generates heat and leads to wheel failure. Apply too much of an angle and the wheel will likely start spalling, which means it will break down prematurely. Grinding wheels can be hard to handle because they remove large cutting fragments from the workpiece, and the noise level is greater than its counterparts.

Flap discs also require proper care to maintain their integrity. The flaps that make up a flap disc are held down with strong adhesive, but that does not make the discs indestructible. If used improperly, such as at excessive angles, or jabbing the discs into tight places, or on an extremely sharp or rough workpiece, the flaps could potentially come apart during use. Further, without proper PPE, the operator or others in the area could get hurt. Flap discs require slightly more pressure than fiber discs to wear away the cloth backing to expose more sharp grain. Most operators leave plenty of life on used flap discs instead of applying enough pressure to wear away the cloth backing. Also, insufficient force will cause “capping”, preventing full use of the product. Capping is when metal adheres to the abrasive grain due to excessive heat and insufficient pressure. This can prevent the grain from fracturing which is needed so it can re-sharpen itself.

Fiber discs require less force to do the same amount of work as grinding wheels or flap discs. The required back-up pad provides a strong backing, similar to flap discs. However, the coating method on the paper allows for an aggressive cut similar to grinding wheels. Most operators prefer the higher cut-rate, lower tool vibration, noise reduction, and ease of use of fiber discs compared to grinding wheels. Fiber discs must be used correctly and with proper PPE. Back-up pads must be in good condition and must be made to be back-up pads. Using old fiber discs or cutoff wheels as back-up pads is dangerous and should not be attempted. Discs that have extreme curl should not be used because they can snag the workpiece, or become too brittle and break while under force. Fiber discs may not have the life of flap discs and grinding wheels, but the lower price point and versatility make them an operator favorite.

Norton BlazeX F980 fiber discs significantly increase cut rate and life in stainless steel and harder-to-grind materials.

As mentioned previously, all three products are safe to use if stored correctly and used properly while wearing the correct PPE. Millions of these products are used safely to build, repair, and create many of the objects around us. While these products are safe when used correctly, it is important to remember never to use a damaged wheel or disc. Damaged wheels or discs should be disposed of immediately and a new one should be fitted for operation.


In a test, welds measuring 2″ × ½” × ¼” were created by a robotic welder, and removed using a grinding wheel, flap disc, and fiber disc. The test results were as follows:

  • Grinding Wheel: First used for removing the weld was the grinding wheel with high quality ceramic abrasive grain. It only took 25 seconds to remove the weld.
  • Flap Disc: Next was a ceramic 36 grit flap disc with a fiberglass back plate. It also only took 25 seconds, comparing nicely to the grinding wheel.
  • Fiber Disc: The ceramic 36 grit fiber disc was tested last, and it had something to prove. It removed the same amount of weld as both the grinding wheel and flap disc, but it only took 17 seconds at lower amps to get the job done.

Norton Blaze R980P flap discs have a premium ceramic alumina grain for long life when grinding stainless steel, cobalt, chrome, Inconel, titanium and other hard-to-grind materials.

If the test was extended to grind for a longer period of time, or if a much larger weld was present, the fiber disc would lose its cut-rate, depending on force and type of metal, in approximately 10-to-14 minutes. Flap discs will continue to wear away and expose new grain, allowing them to last longer than a fiber disc, but their life would be approximately one hour, again depending on force and metal type. The grinding wheel is a long-distance runner and can last longer than flap discs and fiber discs, while doing the same amount of work. Grinding wheels cost more per unit, but if it takes two flap discs or five fiber discs to do the same job, the total cost might be greater using those, not to mention the time it takes the operator to change the discs.

Here are some additional tips:

  • When working on a thick weld on a long I-beam or any large piece of metal, a grinding wheel should be the first abrasive product choice.
  • Removing or blending regular size welds can be done easily with fiber discs or flap discs.
  • Grinding wheels are preferred when metal removal is your only objective, but will not be an optimal choice if the final desired result is polishing.
  • Fiber discs will allow for feathering the area with a soft or medium density back-up pad, at a faster pace.
  • Flap discs are more rigid but leave a nicer finish when compared grit-to-grit to a fiber disc.

All three abrasive products have unique advantages and can overlap applications to some extent. Following some basic rules of thumb and consulting with your abrasives supplier for their advice will help you achieve optimal results.

In metal fabrication and manufacturing operations, various tools use cutting wheels to cut material from a workpiece.

angle, grinder, cutting, disc

What is a cutting wheel? Cutting wheels, or cut-off wheels, differ from grinding wheels in their function and structure. Where grinding wheels use an abrasive to grind large pieces of material off a workpiece from a shallow angle, cutting wheels typically make narrow, precise cuts at 90-degree angles. Consequently, cutting wheels are often thinner than grinding wheels — though they do not have the lateral strength required for side grinding, their minimal thickness makes them better for clean, accurate cuts.

Weiler Abrasives offers several cutting wheels for different applications. We provide everything from 1-millimeter cutting wheels to extended-diameter wheels for larger cuts. This guide to cutting wheels covers the differences between various types of cutting wheels and explains how to choose the right wheel for a given application.


Cutting wheels come in a few different types. Some common types are type 1, type 27, type 41, and type 42, where the various numbers signify the wheels’ different shapes and properties.


A type 1 cut-off wheel, also known as a type 41 cut-off wheel, is completely flat. It is typically considered the most efficient type of wheel for general all-purpose cutting. Because it lacks a depressed center, it provides more cutting surface and minimizes interference with the workpiece.

The flat profile helps create deep 90-degree cuts into a workpiece. It allows for the maximum depth of a 90-degree cut at the expense of a small amount of visibility for the operator. Though their straight profile and the way they mount close to the guard can diminish visibility for the operator, type 1 cutting wheels are exceptionally useful in grinders, die grinders, high-speed saws, stationary saws, and chop saws.


Instead of being completely flat, a type 27 cut-off wheel, also known as a type 42 cut-off wheel, has a depressed center. The depressed center allows for added clearance when the operator is working at a constrained angle, though it gives the wheel limited cutting ability when working around corners, profiles, or extrusions. The depressed shape allows for a raised hub as well to hold the wheel securely in place.

The profile of a depressed-center cutting wheel gives the operator a better view of the cut, and it provides the ability to flush-cut because the raised hub means the locking nut can be recessed. Type 27 cutting wheels are designed for right angle grinders.


Cutting wheels typically contain a few different materials — primarily the grains that do the cutting, the bonds that hold the grains in place, and the fiberglass that reinforces the wheels.


The grains within the abrasive of a cutting wheel are the particles that perform the cutting.

Grains may come in several types. Common types of grains for cutting wheels include ceramic alumina, zirconia alumina, aluminum oxide, and silicon carbide.

  • Ceramic alumina: Ceramic alumina performs exceptionally well on steel, stainless steel, and other hard-to-cut metals, including inconel, high nickel alloy, titanium and armored steel. When used and maintained properly, it offers a superior lifespan and cut, and it tends to cut cooler than other grains, so it reduces heat discoloration.
  • Zirconia alumina: Zirconia alumina provides superior cutting for steel, structural steel, iron, and other metals, and it is ideal for rail cutting and other heavy-duty applications. It offers a fast cut and a long life and holds up under extreme pressure.
  • Aluminum oxide: Aluminum oxide is one of the most common abrasive grains. It provides a fast initial cut rate and consistent performance for steel and other metal.
  • Silicon carbide: Silicon carbide is an extremely hard grain that produces very sharp and fast cutting. However, it is also friable, meaning it is not as tough as other grains.

The grain’s grit helps determine its physical and performance properties as well. The grit refers to the size of the individual abrasive particles, in the same way sandpaper grains receive classification by their size. Grit sizes range from 16 to 60, with smaller numbers indicating larger, coarser particles and larger numbers indicating smaller, finer particles.


The bond of a cutting wheel is the substance that holds the abrasive grains in place.

Manufacturers often refer to the grade, or hardness, of a wheel. The grade signifies not the hardness of the abrasive grains themselves but the hardness of the bond holding them in place. Generally, under identical conditions, a harder bond means the cutting wheel will have a longer lifespan, whereas a softer bond means the cutting wheel will have a shorter lifespan.

A softer bond does provide certain advantages — it sheds its grains more rapidly to provide a faster cut. With a stronger bond, the bond may hold the grains in place after they have become worn. A softer bond releases them faster to reveal fresh, sharp grains more often and increase the wheel’s cut rate.

With certain metals, it is important not to introduce contaminants into the metal when cutting. When cutting stainless steel and aluminum, always make sure the abrasive contains less than 0.1% of chlorine, iron, and sulfur, ensuring it is contaminant-free. Contaminant-free products will have identifying labels.

One of the bonds commonly used with abrasive grains for cutting wheels is resinoid. Resinoid bonds contain organic compounds. They tend to have better shock resistance than other types of bonds and can withstand operation at elevated peripheral speeds. They are ideal for cut-off applications, and they allow for self-sharpening by exposing new grains. Some specialized bonds are resin-over-resin bonded. These bonds provide additional moisture and heat resistance, as well as a stronger overall bond to make better use of the grains.


Cutting wheels contain fiberglass that may provide single, double, or triple reinforcement. Single reinforcement relies on a single layer of fiberglass and is useful for delivering exceptional cutting speed while reducing burrs on the workpiece. Double and triple reinforcement use multiple layers of fiberglass to provide added support for high-vibration and heavy-duty industrial applications.

At Weiler Abrasives, all our cutting wheels for right angle and die grinders have two layers of reinforcement. We do offer some single-reinforcement wheels in our large-diameter chop saw line and some triple-reinforced wheels in our new high-speed gas and electric saw wheel line.


With cutting wheels, the tool the operator has access to will often determine the wheel size, and selecting the correct size for the given application is also essential. Choosing the correct size involves calculating the right rate of revolutions per minute (RPMs) — the RPM rating of the cutting wheel should match or exceed the RPM rating on the grinder that will use it. In addition to verifying the RPM rating, it is also important to ensure that the wheel fits on the tool without interfering with or removing the guard.


A wheel’s RPM rating tends to correspond with its diameter and the tool it is designed for. Common cutting wheel diameters range from 2 to 4 inches for die grinders, 4 to 9 inches for angle grinders, and 12 to 20 inches for chop, stationary, or high-speed saws.


The right wheel thickness often depends on the precision and accuracy necessary for the cut. For a highly precise cut, a thinner wheel can perform with greater accuracy and precision. They cut more quickly and generate less heat. Thinner wheels also remove less material with each cut, which is ideal when making repairs or fitting up parts. The tradeoff is that they tend not to last as long as thicker wheels under identical conditions. In applications where precision and accuracy are not as critical but longevity is, a thicker wheel may be suitable.

Weiler Abrasives offers two ultra-thin high-performance cutting wheels — the Tiger Zirc Ultracut 1-millimeter and the Tiger Inox Ultracut 1-millimeter. Both of these cutting wheels come in 4 1/2- or 5-inch diameters. The Tiger Zirc Ultracut 1-millimeter offers an ultra-fast cutting rate and long life, and it is ideal for cutting thin sheet metal, tubes, profiles, and small cross-section rods. The Tiger Inox Ultracut 1-millimeter is ideal for stainless steel because it is contaminant-free.

Weiler Abrasives has an exciting new line of chop, stationary, and high-speed saw wheels as well. The chop saw wheels have a 3/32-inch thickness, and the high-speed saw wheels and stationary saw wheels have a 1/8-inch thickness. These cutting wheels are ideal for cutting applications in the metal fabrication, construction, and rail industries, and some of the specialized models can provide precise rail cutting, burr-free cutting, and stud cutting for heavy-duty applications.


So far, we’ve discussed how types 1, 27, 41, and 42 cutting wheels offer distinctive shapes for different cutting applications. We’ve delved into the various common grains used in cutting wheels and how they are optimized for use on different metals, and we’ve explored the way diameter and thickness affect wheel speed and precision. Now let’s look into a few applications for industrial and professional cutting wheels and how to choose the right wheels for these uses.


In general metal fabrication, 0.045-inch wheel diameters are common choices. With thinner materials, an operator may want to choose a 1-millimeter wheel instead for greater precision, less heat generation, and fewer burrs that will require removal before welding. The choice of grain will likely depend on the material composition of the workpiece — higher-performing grains for structural steel and difficult-to-cut metals, contaminant-free wheels for stainless steel.


In metal pipe fabrication, the choice of cutting wheel often depends on the diameter of the pipe to be cut. For a 3/4-inch or smaller pipe, a 4 1/2-inch diameter will usually be sufficient. For a pipe of up to 2 1/2 inches, a 6-inch cutting wheel is effective, and for a pipe of up to 3 1/2 inches, a 9-inch cutting wheel is often most suitable. It’s also advisable to choose the thinnest wheel possible to minimize heat and friction and to use a type 1 wheel for a deeper cut unless the application imposes a particular constraint. For larger pipe often found on the pipeline, a depressed-center cutting wheel provides added clearance when working at a constrained angle, and 0.045-inch wheel thickness is ideal for cutting applications in fabrication yards or on the right of way for field repairs.


When an operator is working on the confined, hard-to-access spaces of a ship, making a cutting wheel last as long as possible is often a priority. For this reason, the operator will often want to choose a harder, potentially longer-lasting wheel like Tiger Ceramic. However, when operators must use air tools whose hoses have stretched over long distances to access difficult areas of the ship, the tools may be underpowered. In this case, wheels with a soft bond will be ideal because they make it easier to maintain a fast cut. In shipbuilding, the work material often influences the cutting wheel selection. When working with aluminum, an operator may want to select a cutting wheel that will not load or gum up, like Tiger Aluminum.


Preparing for welding typically involves exact metal cutting. With a basic cut-off operation, precision is not critical, but with complex work or repairs that need to preserve the initial aesthetic qualities of the material, precision can save time and money. Using a 0.045-inch cutting wheel — a little more than a millimeter thick — is common in welding to allow for precise and accurate cuts. For precise cuts on thin sheet metal, profiles, and small diameter rods, a 1-millimeter UltraCut wheel will provide smooth cutting and exceptional control for clean, ultra-precise cuts.


Modern railways use hard-to-cut alloy steels, so a high-performance cutting wheel is necessary for high-speed gas saws. A self-sharpening zirconia alumina grain that retains a high cutting performance throughout the life of the wheel offers excellent performance. The Tiger Zirc 14- and 16-inch cutting wheels are designed specifically for high-speed gas saws and deliver the high-performance solutions needed to increase productivity and profitability.


Building and construction sites feature a wide variety of metal cutting applications. Operators often look for a wheel that can do it all, from cutting off rebar to making long cuts on sheet metal. Many times, an aluminum oxide wheel provides the right mix of versatility, performance, and price. The Tiger AO line offers both flat and depressed-center cutting wheels in various sizes for die and right angle grinders. The Tiger AO line also expands into larger sizes from 12 to 16 inches for chop saws and high-speed gas and electric saws.

These large-diameter cutting wheels have several signature wheels designed with the construction industry in mind. For chop saws, the line includes a wheel designed for stud cutting and options for burr-free cutting that feature a single layer of fiberglass. The high-speed saw offering includes wheels with three layers of fiberglass for added support in heavy-duty cutting applications.

A (fourteen) 14 inch grinder is 356mm

Common Angle Grinder Sizes in Australia

Grinders also come in various other sizes, such as a 3 inch 76mm angle grinder, however these are the most common sizes used in Australia.

Different Types Of Grinding Disc

Silicon Carbide Grinding Discs

These discs are purpose made for the shaping of metals. They also allow for the efficient removal of materials and prevention of surface damage. Use of the grinding discs is expected to minimise the need for subsequent processing, allowing preparation time to be saved.

These discs are purpose made to cut hard items and materials such as rods, bolts, rebars, and metal piping.

Sanding Pads and Discs

Sanding pads allow for the efficient removal of old paint in the process of surface preparation. They are also suitable for coarse and fine sanding.

Grinding Wheels and Discs

The grinding wheel is an expandable wheel, made from an abrasive compound. It allows for a variety of grinding and abrasion functions. Grinding wheels and other forms of bonded abrasives have two key features – the abrasive grains which allow for efficient cutting, and the bond which combines and supports the grains during the cutting process.

Grinding discs are suitable for metal and stone applications across a range of machine sizes. The main use of such discs is in the removal of materials. However, they can also be used for the finishing and preparation of stone and metal surfaces.

Wire Brush Wheels

These wheels allow for the effective removal of paint and rust. They also enable the removal of burrs from rough-cut metal surfaces.

Diamond Cutting Wheels and Discs

These wheels and discs are particularly suitable for the cutting of concrete, tile, masonry, and granite. However, it is important to make the appropriate selection and use of the cutting blade in accordance with the technique. There are diamond blades suitable for dry and wet cutting.

Aluminium Oxide Grinding Wheels

These oxide-based wheels are suitable for a wide range of applications, including woodworking and the cutting of crumbly materials like cutting boards.

Flap Discs and Wheels

The flap disc performs a similar function to the wire brush yet features flaps rather than wires. This allows for the effective combination of weld beads with the rest of the metal.
