Polygon Solution Inc.'s new 'Made in USA' 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. The new 'Made in USA' broach will have its official debut at the International Manufacturing Technology Show (IMTS), September 8-13, 2014 in Chicago, IL.
