Contaminant-Free Grinding Wheels for Angle Grinders—Use on Metals

Image of Product. Front orientation. Contains MultipleImages. Grinding Wheels. Contaminant-Free Grinding Wheels for Angle Grinders—Use on Metals.

The absence of iron, sulfur, and chlorine in these wheels means they won’t corrode or discolor stainless steel. They are also known as INOX wheels, 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.

Contaminant-Free Angle Grinder Cutoff Wheels for Stainless Steel


	Side View

Prevent corrosion and discoloration on stainless steel—these wheels contain less than 0.1% iron, chloride, and sulfur contaminants. They have an aluminum oxide grit and 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.

Flush-Cut Contaminant-Free Angle Grinder Cutoff Wheels for Stainless Steel


	Side View

Also known as Type 27, raised-hub, and depressed-center cutoff wheels, these wheels outperform Type 1 wheels when making flush cuts. They contain less than 0.1% iron, chloride, and sulfur contaminants, so they won't corrode or discolor stainless steel. Wheels are aluminum oxide abrasive that is reinforced with two layers of fiberglass mesh.

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