Fuller Tapered Drill & Countersink Set with 3/8 in. Plug Cutter

Fuller® Tapered Drill Countersink Set with 3/8-in. Plug Cutter

The Fuller® Tapered Drill Countersink Set is designed specifically for installing tapered wood screws with clean, accurate results. Each combination drill and countersink creates a properly sized tapered pilot hole while simultaneously forming an 82° countersink for the screw head. Matching the tapered drill to the screw helps engage the threads along the length of the pilot hole, providing a precise fit and helping produce strong, professional-looking woodworking joints.

These tapered drill countersinks are ideal for cabinetmaking, furniture construction, trim work, general woodworking, and other projects where tapered wood screws are used. The integrated countersink allows you to drill the pilot hole and recess the screw head in a single operation, helping save time and eliminating the need to switch between separate drill bits and countersink tools.

Three Common Tapered Screw Sizes

The set includes three tapered drill and countersink combinations for commonly used wood screw sizes. Choose the appropriate bit based on the screw thread size to create the proper pilot hole and countersink.

• #6 screws: Use the 9/64-in. tapered pilot bit.
• #8 screws: Use the 11/64-in. tapered pilot bit.
• #10 screws: Use the 13/64-in. tapered pilot bit.

Adjustable Drilling Depth

For accurate and repeatable results, the drilling depth can be adjusted by changing the length of the drill bit. Use the included 3/32-in. hex-key wrench to make the adjustment and position the bit for the desired screw depth. This adjustable design makes it easy to accommodate different material thicknesses and screw lengths.

Built-In 82° Countersink

Each tapered drill is fitted with a 3/8-in. diameter, 82° countersink that creates a clean recess for the screw head. The countersink helps tapered wood screws sit neatly below or flush with the surrounding surface, making the set especially useful for fine woodworking and applications where a clean finished appearance is important.

3/8-in. Quick Change Plug Cutter Included

The set also includes a 3/8-in. Quick Change Plug Cutter for creating matching wood plugs to conceal countersunk screw heads. After fastening, plugs can be installed over the screw for a clean, finished appearance that blends with the surrounding wood.
