Polygon Solution Inc.’s new Made in the U.S.A. broach is a rotary broach with multiple text letters allowing machinists to stamp or mark their part in a lathe or milling machine without removing the part from the machine. Polygon’s rotary broaching system is usually used for making hexagon or square holes in precision machined products.

Polygon Solutions first introduced its award-winning adjustment free rotary broach toolholder in 2010, ideal for CNC machines because of maintenance-free sealed bearings and a pressure relief system. The company later announced a series of letter broaches in 2012. The broaches have letters or numbers and are inserted into Polygon’s broach holder to mark parts. The different identifying marks improve quality to distinguish between mixed lots of parts made in the same machines.

Polygon’s new broach is not limited to the Made in the U.S.A. mark. The company sells its tools worldwide.
