Grinding Bits for Metals

Made of aluminum oxide, these bits are well suited for use on most metals and materials that are not heat sensitive.

Rubber-Cushioned Abrasive Grinding Bits for Metals

The abrasive grains in these bits are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits.

Rubber-Cushioned Abrasive Grinding
Bits without Shank for Metals

Bits thread onto mounted shanks so you can quickly switch head shapes without removing the shank. The abrasive grains are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits.

Rubber-Cushioned Abrasive
Grinding Bit Sets for Metals

The bits in this set have rubber blended into the abrasive, which cushions during grinding to produce a smooth to extra-smooth surface texture.
