Product Overview

This tool cuts space for the sight screw head , allowing it to be countersunk into the metal. Counterboring a receiver or barrel for sight screws results in a professional looking installation that will add beauty and value to your gun.


  • Cuts space for sight screw head (allows head to be countersunk into metal)
  • Should be used in a drill press with all work held in precision fixtures for best results
  • Description lists either hight speed steel or carbide. Carbide will last longer than high speed steel, however both must be used carefully as with any cutting tool.
