Internal Diameter Toolroom Grinding Wheels for Metals
Typically used with cylindrical, surface, and ID grinders, these wheels are specially designed to grind the inside diameter of workpieces. They’re often used to make bearings.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Flush-Cut Angle Grinder Cutoff Wheels for Hard Metal
Made of ceramic alumina, these wheels last 10 times longer than standard cutoff wheels when cutting hard metal, such as tool steel. They’re reinforced with two layers of fiberglass mesh. These wheels, also known as Type 27, raised hub, and depressed-center cutoff wheels, outperform Type 1 wheels when making flush cuts.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Angle Grinder Cutoff Wheels for Hard Metal
Made of ceramic alumina or a combination of ceramic alumina and zirconia alumina, these wheels last up to ten times longer than standard cutoff wheels when cutting hard metal such as Inconel, Hastelloy, and tool steel. Wheels are reinforced with two layers of fiberglass mesh.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Straight Grinder Cutoff Wheels for Hard Metal
The combination of ceramic alumina and zirconia alumina in these wheels lasts up to ten times longer than aluminum oxide when cutting hard metal such as Inconel, Hastelloy, and tool steel. Wheels are reinforced with a layer of fiberglass mesh. Choose coarser grit for fast cuts; choose finer grit for smooth cuts.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Bench and Surface Grinder Cutoff Wheels for Hard Metal
Made with boron nitride, second only in hardness to diamond, these wheels are highly wear resistant, so they easily cut steel with a Rockwell hardness of C50 or greater, including alloy steel, A2, D2, and T15 tool steel. While these wheels are not as hard as wheels made with diamond, they dissipate heat better.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Multipurpose Portable Cutoff Saw Wheels
Make burr-free cuts in a variety of materials—from rubber to metal to stone. Made from a blend of silicon carbide and aluminum oxide abrasives, these cutoff wheels won’t clog or burn when slicing through nonmetals. They’re often used to cut hard or thick pipe, sheets, and bars to size.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.
