Gen 4 ULTIMAX Cutting Head

Taper-Lock cutting heads will only fit the Gen 4 trimmer (Not for the Gen 2 or 3 Trimmer) 

Cutter bodies are machined from 416 stainless steel. The ID chamfer is 14° and the OD chamfer is 30°, the blades are made from carbide. The Taper-Lock cutters can be order either  factory adjusted or they can be adjusted by the end user. Henderson Precision has videos on their website that will walk you through the process. The trimmer utilizes a draw screw taper on taper design for precision alignment of the cutting head and shaft.  All pilots are Caliber-Specific.
