Angle Grinder Cutoff Wheels for Hard Metal


	Side View

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 nickel, Hastelloy nickel, 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.

Flush-Cut Angle Grinder Cutoff Wheels for Hard Metal


	Side View

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.

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.
