Fuller 3/8-in. x 3/32-in. Drill Countersink

The Fuller 3/8-in. x 3/32-in. Drill Countersink combines pilot-hole drilling and countersinking into one efficient operation. Designed for woodworking and general drilling applications, this countersink slips onto a compatible drill bit to create a clean pilot hole and recessed area for a wood screw in a single step.

Drill and Countersink in One Step

Save time and simplify your drilling process by using the countersink with the appropriate 3/32-in. drill bit. Once installed, the countersink allows you to drill the pilot hole and create the countersink at the same time, helping produce consistent results for screw installation.

Adjustable Drilling Depth

Use a stop collar to control the drilling and countersinking depth. This makes it easier to achieve repeatable results across multiple holes and helps prevent drilling deeper than necessary.

Easy to Use

The Fuller countersink is designed to slip onto a drill bit of the specified diameter, making setup quick and straightforward. It is a practical accessory for woodworkers, cabinetmakers, furniture builders, and DIY projects where clean, professional-looking screw holes are important.
