Drill Bit Countersinks

Designed for drilling into wood, these drill bits have an integrated countersink and produce a chamfered hole with a tapered opening that allows screws to install flush with the surface of the workpiece. The height of the countersink can be adjusted to suit the hole depth, and the drill bit can be replaced when worn.
