Counter-boring the trigger guard will result in a simple, professional looking installation of the trigger guard screws.
- Cuts space for trigger guard 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.
