    Run these high-density aluminum oxide wheels at higher speeds than standard cutoff wheels to make quick cuts in aluminum, iron, stainless steel, and steel. Wheels are reinforced with a layer of fiberglass mesh.
    Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

    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.
