Werewolf Parts supplies carbide trencher teeth and conical trenching picks for chain trenchers, trenching wheels, roadheaders, scalers, augers, core barrel drilling, grinders and road planing, in 22mm, 25mm, 30mm and 38mm shanks. Shop the 7/8" Shank (22mm) for lighter trenchers, the 1" Shank (25mm) for wheels, crushers and roadheaders (Vermeer and Ironwolf compatible), the 1" Shank, Internal Retainer for augers and core barrel work, the 1" Shank, Wide Collar, made in the USA, the 1-3/16" Shank (30mm) for crusher and roadheader duty, and the heavy-duty Step Shank, 24 Carbide (38mm) for large chain trenchers in hard ground. Match shank diameter and retainer type first; rock teeth just mean a bigger tip, not a harder one. Have an OEM number like C35R or BTK11? Send it with your shank diameter and we'll confirm the match.
