ADJUSTMENT-FREE | No set-up is required !

Polygon’s rotary broach holder does not require any adjustment and is designed with an easy plug-and-play feel. The fixed length broach is locked into the spindle with a simple set screw. The HT rotary broach holder is suitable for experienced machinists and new operators.

No machine is prefect, and many have slight misalignments between the part and the tool holders. Polygon’s innovative rotary broach holder is designed for this situation and has a small amount of endplay. The high quality bearing allows the broach to center itself in the chamfer before broaching the finished hole.


The award winning design of the HT broach holder also includes a pressure relief system. Each standard broach includes a through hole that allows coolant, cutting oil and air to escape when broaching blind holes. The fluid and air escapes through a port on the side of the rotary broach holder. Relieving pressure is a critical operation for improving cutting tool and machine life.

MAINTENANCE-FREE BEARINGS | No Hourly Greasing Required!
