About Sanding Abrasives

Recessed

Typically used with cylindrical, surface, and ID grinders, these wheels are specially designed to grind the inside diameter of workpieces. They’re often used to make bearings.

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

Rubber-Cushioned Abrasive Grinding Discs without Shank for Metals

The abrasive grains in these discs are blended with rubber, which cushions during grinding to produce a smoother surface texture than other discs with similar grits. Discs attach to your grinder with a shank.

Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
