Flush-Cut Angle Grinder Cutoff Wheels for Metal


	Side View

Also known as Type 27, raised-hub, and depressed-center cutoff wheels, these wheels outperform Type 1 wheels when making flush cuts in metal. Wheels 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.
