DESCRIPTION
A precision-ground abrasive made for extended usage. This gray sharpening stone has a diameter of 5/32".

USES
Ideal for sharpening chain saw blades, quickly and easily.

TIPS
- For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collet or chuck to hold onto.

- Keep a light touch; too much pressure can break the grinding stone
