Yonico Counter Sink and Screw Slot Router Bit - 1/2" Shank - 14199

A countersink is used when the fastener’s head is conical in shape as in the case of a typical wood screw where the screw head needs to be flush or sit below the surface of the work piece. Alternatively, a counterbore hole is typically used when the fastener’s head, such as a round head screw, is required to sit flush with or below the level of a workpiece's surface. Our bits are constructed with a single solid carbide tip with virtually no centre web resulting in a very high-quality tool.
