Counterbore drills are used to make a counterbore hole in the material when the head of a fastener, such as a hex head or socket head cap screw, is required to be flush with or below the level of a workpiece’s surface. For a spot-face, material is removed from a surface to make it flat and smooth, usually for a fastener.
SOMTA Counterbore Drills are ideal for drilling holes in handle material to fit inter screws or pivot screws.
The 7mm x 5mm is the standard size for the INTERSCREWS also available on this website.
