Fuller 1/2 in. x 7/32 in. Drill Countersink

Fuller 1/2-in. x 7/32-in. Drill Countersink

The Fuller 1/2-in. x 7/32-in. Drill Countersink lets you drill a pilot hole and create a clean countersink in one efficient step. Designed for woodworking and general fastening applications, this countersink slips onto a compatible drill bit, helping you prepare accurately sized holes for screw heads and wood plugs.

Drill and Countersink in One Step

Save time and simplify your drilling setup by combining pilot-hole drilling and countersinking into a single operation. The countersink mounts directly onto a drill bit with the specified diameter, allowing you to drill the pilot hole and form the countersink at the same time.

Designed for Plug Applications

The 1/2-inch countersink is sized for creating a recess suitable for the desired plug size. This makes it a useful choice for woodworking projects where screws need to be recessed and covered with matching or contrasting wood plugs for a clean, finished appearance.

Adjustable Drilling Depth

Use a stop collar to control the drilling depth and achieve consistent results from hole to hole. Proper depth control helps create uniform countersinks while reducing the risk of drilling deeper than necessary.

This Fuller drill countersink is a practical addition to a woodworking drill-bit collection. It is well suited for cabinetmaking, furniture construction, trim work, repairs, and other projects that require recessed screw holes.
