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 GT 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 GT 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.

Polygon’s high quality FAG brand sealed bearings provide the quality required for today’s demanding machinists and their machines. For more than 120 years, the Schaeffler Group’s FAG brand has been one of the leading manufacturers of precision bearings for the automotive, mechanical engineering and aerospace industries. Polygon’s GT series broach holder is a premium tool that will never include inferior bearings.

Sealed bearings save you from having to grease the holder every one or two hours (as recommended for screw machine era holders). The superior quality of the seals is backed up by the broaching industry’s only ONE YEAR BROACH HOLDER WARRANTY. Additionally, you will not need to purchase, store and inventory costly grease guns, tubes and work instructions.

One year warranty is available on all GT and Micro Rotary Broach Tool Holders from Polygon Solutions. We are the only company in the rotary broach industry confident enough in our tool holder to offer a full 1 year warranty against bearing failure.
