High-Performance Grinding Wheels for Angle Grinders—Use on Metals

A blend of ceramic alumina and zirconia alumina removes material at a 50% faster rate than our Long-Life Grinding Wheels. Wheels are also known as Type 27 wheels, raised-hub wheels, and grinding discs.
Wheels are designed for grinding metal surfaces and removing weld seams.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Grinding Wheels for Angle Grinders—Use on Soft Metals

Bonded without any wax or rubber filler, these wheels resist material buildup. They are also known as Type 27 wheels, raised-hub wheels, and grinding discs.
Wheels are aluminum oxide, which is the most common abrasive used in grinding metal. They are designed for grinding surfaces and removing weld seams.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Grinding Wheels for Straight Grinders

Use these wheels for heavy material removal in one spot or along a weld seam. They are also known as Type 1 wheels and snagging wheels.
Wheels are aluminum oxide, which is the most common abrasive used in grinding metal.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Floor Sanding Discs

Use with commercial floor buffing machines to sand floors.
Silicon carbide discs are sharp enough to sand concrete floors. You can also use them to sand wood floors, but they’ll wear out quicker than ceramic alumina discs. Clog-resistant discs have a coating that prevents dust and debris from building up on the abrasive surface.
