The set includes a chamfer cutter, handle, one steel pilot, and is packaged in a polypropylene box, with additional pilots available for various calibers.
Constructed from hardened steel, the chamfer cutter is available in either ½" or 5/8" diameter sizes to accommodate different barrel and cylinder mouths.
