Fuller 1/2 in. x 9/64 in. Drill Countersink

Fuller 1/2-in. x 9/64-in. Drill Countersink

The Fuller 1/2-in. x 9/64-in. Drill Countersink combines pilot-hole drilling and countersinking into one efficient operation. Designed for woodworking and fastening applications, this countersink slips onto a compatible 9/64-in. drill bit to create a clean, consistent recess for a 1/2-in. wood plug.

Drill and Countersink in One Step

Save time and simplify your drilling setup by creating the pilot hole and countersink at the same time. The countersink is designed to work with any type of drill bit in the specified diameter, making it a versatile addition to a woodworking drill-bit collection.

Designed for 1/2-in. Wood Plugs

The 1/2-in. countersink creates a properly sized recess for concealing screw heads with 1/2-in. wood plugs. This helps produce a clean, finished appearance on furniture, cabinetry, trim, and other woodworking projects.

Adjustable Drilling Depth

Use stop collars to control drilling depth and maintain consistent results from one hole to the next. This is especially useful when making multiple countersunk holes that need a uniform appearance.
