The Cutter Shaft does most of the hard work of a Forster Case Trimmer: a bit with a cutting blade trims the case neck; the high-alloy steel shaft holds all of the rotating specialized case conditioning accessories.

Four staggered-tooth cutting edges provide fast, smooth, chatterless cutting for perfectly square case mouths. Cuts are bright and uniform.

Also included is an 8-32 x 1/8" Set Screw for locking Pilots.

This Cutter Shaft fits the Power Case Trimmer only, and it is the standard .4902" diameter Shaft included with the Trimmer for .171" to .459" calibers. Additional Cutter Shafts are also available for 17 caliber cartridges, as well as for other Trimmers.
