SCREW PILOT NO.8 CARDED
90° Countersink with drill bit
A convenient power tool accessory. Allows you to drill a hole and simultaneously countersink the hole for screws.
A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material.
This accessory will just allow you to drill and countersink in a singel step. Accurate at all times and a very neat job.
A countersink is a conical
hole cut into a manufactured object.
