Angle Grinder Cutoff Wheels for Masonry and Concrete


Type 1 Grinding Wheel	Type 27 Grinding Wheel	Type 1 (Side View)	Type 27 (Side View)

Make cuts in hard, brittle materials such as firebrick, stone, and concrete. Wheels are made of silicon carbide abrasive that is reinforced with a layer of fiberglass mesh.

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

Type 27 Grinding Wheel—Type 27 cutoff wheels outperform Type 1 wheels when making flush cuts. Also known as raised-hub and depressed-center cutoff wheels.

Multipurpose Bench-Top Cutoff Saw Wheels


	Side View

From stone to rubber to metal—slice through a variety of materials with the same cutoff saw wheel. Made of silicon carbide and aluminum oxide abrasives, these wheels won’t clog or burn when cutting through nonmetals. Attach them to your bench-top cutoff saw to make burr-free cuts in pipes, bars, and sheets. You shouldn’t use these wheels with handheld saws.

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

Bench-Top Cutoff Saw Wheels for Titanium


	Side View

Made from bonded silicon carbide abrasives, these wheels slice through titanium, one of the hardest materials to cut. Designed to make smooth, burr-free cuts, they cut faster and stay sharp longer than wheels made with aluminum oxide abrasives. Use them to cut bars, sheets, and tubing into manageable pieces. Not for use on hand-held saws.

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