Bench and Pedestal Grinding Wheels with Rubber-Cushioned Abrasive for Soft Metals

The silicon carbide abrasive in these wheels is suspended in rubber for a cushioned grind with light material removal.

Silicon carbide cuts through soft metals without generating much heat or causing material buildup.

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

Bench and Pedestal Grinding Wheels for Carbide, Ceramics, and Glass

Abrasive Face

The perforated honeycomb pattern cuts carbide, ceramics, and glass without the need for cleaning.

Wheels are made of diamond-coated steel molded onto plastic, so they can be used wet or dry. Diamond is extremely hard and wear resistant.

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

Heavy-Removal Bench and Pedestal Grinding Wheels for Metals

Designed to stand up to heavy use, these wheels remove more material than our General Purpose Grinding Wheels.

Wheels are for grinding, deburring, and sharpening. They include one of each reducer bushing listed. The smallest bushing size shown is the smallest allowed for that size wheel.

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

For Aluminum, For Brass, and For Bronze—Wheels for aluminum, brass, and bronze are silicon carbide, which cuts through soft metals without generating much heat or causing material buildup.

For Steel and Stainless Steel—Wheels for steel and stainless steel are aluminum oxide, which is the most common abrasive used in grinding metal.
