1 - Peterson recommends using the High Abrasion bits when grinding leaves that are highly contaminated with sand.

2 - The Bear Claw bit is an extremely aggressive tool that is impact sensitive and will work best in a contaminant-free environment. Due to the highly aggressive nature of this bit, Peterson recommends a balanced rotor of Bear Claw bits combined with our Standard 6-Pass or Heavy Duty 8-Pass bits. 3 - Due to material variations in this grinding application which can increase side load impacts, Peterson recommends the saddleback or railed version of this bit.

4 - Peterson recommends using the Knife Edge bit in a clean, contaminant-free environment.

Heat Treated Steel ForgingOur Knife Edge bits are made from a high quality alloy steel which is heat-treated to a high Rockwell rating for improved wear life. These sharp, highly aggressive bits increase production and reduce fuel consumption when grinding logs and forest residues in a clean, contaminant free environ-ment.

Cast CarbideCast Carbide technology is a Peterson exclusive. Our cast carbide material combines the hardness of cemented tung-sten carbide with the tough-ness of air-hardening steel to form a unique matrix that is extremely wear-resistant in abra-sive applications. The most cost-effective bit on the market for asphalt shingle grinding.

Carbide OverlayCarbide Overlay technology is the industry standard, how-ever, Peterson carbide overlay bits are anything but standard. We embed wear-resistant carbide granules in a tough, abrasion resistant steel-weld material which is applied to a heat-treated steel forging. The result is a superior bit ideal for high-impact applications.
