Premium-grade abrasive materials and two layers of fiberglass mesh reinforcement give these wheels a longer life than standard cutoff wheels when cutting metal such as iron, stainless steel, and steel. 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.

Straight Grinder Cutoff Wheels for Hard Metal
 | |
Side View |
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 nickel, Hastelloy nickel, 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.
