APT CC260 indexable countersink with a 60-degree included angle and positive rake is a single-insert countersinking tool designed for SPGH433 inserts. It features a 1/2" shank and a maximum cutter-body diameter of 1-3/4", making it suitable for countersinking and chamfering holes to seat flat-head screws. The CC260 is intended for use with indexable countersink holders, enabling you to replace the insert rather than resharpen the body and maintain precise edge geometry.
