6XG74 Drill Bit Countersinks

Bulk orders will be discounted, please contact us.

Drill bit countersinks combine a drill bit and a countersink in one tool. The height of the countersink can be adjusted to suit the hole depth, and the drill bit can be replaced when worn. These tools create a chamfered hole with a tapered opening that permits screws to install flush with the surface of the workpiece for a neat appearance.
