Fuller 3/8-in. x 7/64-in. Drill Countersink

The Fuller 3/8-in. x 7/64-in. Drill Countersink makes it easy to drill a pilot hole and create a clean countersink in one operation. Designed for efficient woodworking and fastening applications, this countersink attaches to a compatible drill bit to provide consistent results and a professional finished appearance.

Drill and Countersink in One Step

Simply slip the countersink onto a drill bit with the specified diameter and drill the pilot hole and countersink at the same time. This streamlined setup helps save time and reduces the need for separate drilling and countersinking operations.
