A large grinding surface, combined with a thick layer of rough abrasive removes more material than other wheels. They are also known as Type 11 wheels, flared-cup wheels, snagging wheels, and cup stones.

Wheels are often used to grind weld seams and remove flaws from castings. The full backing provides additional support.

Wheels for steel are aluminum oxide, which is the most common abrasive used in grinding metal.

Wheels for steel and stainless steel are zirconia alumina, which grinds faster and lasts longer than aluminum oxide.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
