Bench Grinder Cutoff Wheels for Carbide, Ceramic, and Glass


	Side View

These steel wheels have a diamond grit edge, so they last longer than standard bench-grinder cutoff wheels when cutting hard, nonferrous materials such as carbide, ceramic, and glass.

Smooth-Cut Bench Grinder Cutoff Wheels for Metal


	Side View

An extra-fine layer of fiberglass mesh reinforcement allows these wheels to make smoother cuts than standard bench-grinder cutoff wheels when cutting metal such as aluminum, iron, stainless steel, and steel.

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


	Side View

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.

Bench Grinder Cutoff Wheels for Metal


	Side View

Use these wheels to cut through metal such as aluminum, iron, stainless steel, and steel. They are reinforced with two layers 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.

Cutoff Saw Wheels for Metallurgical Testing


	Side View

Create the nearly polished finish required for testing metal with these non-reinforced aluminum oxide wheels. They are not for use on hand-held saws.

Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.
