TEWORDA Countersink Drill Bit Set 15-Piece — Nitrided HSS, Tapered Bits, Plug Cutters, 1/4 Hex Quick Change

Precision wood drilling and flawless plugs, all in one kit

TEWORDA's 15-piece countersink set is engineered for everyday woodworking tasks—cabinetry, furniture assembly, and DIY projects. The coordinated collection keeps your tools organized, helping you move quickly from pilot hole to finished reveal. By combining cutters, depth controls, and fastening bits, it supports a wide range of applications with one purchase.

What’s inside the kit

This all-in-one solution includes tapered countersink bits in multiple sizes, wood plug cutters, depth stop rings, and fastening accessories. The items are designed to work together for accurate depths, clean plugs, and flush screw seating, reducing setup changes mid-project.

• Two #4 bits (7/64in), two #6 bits (9/64in), one #8 (11/64in), one #10 (3/16in), one #12 (7/32in)
• Two wood plug cutters (3/8in and 1/2in)
• Two depth stop rings (3/8in and 1/2in)
• PH1 and PH2 screwdriver bits
• One extension shaft
• One Allen key

Quality you can feel

The bits are made from premium high-speed steel with a nitrided surface. This treatment helps reduce heat buildup and retains edge sharpness longer than standard HSS, with up to 40% longer edge life. Polished flutes also help wood chips eject quickly, minimizing clogging and keeping the cut clean.

Precision you can trust

The set features an adjustable depth control system with lockable stop collars that steady pilot holes. An 82° countersink angle guides screws to sit flush, while the tapered guides align for consistent results—even on beginner projects.

Clean plugs, better fits

Efficient wood plug cutters are designed to produce plugs that fit snugly into the recess, with cutting edges that minimize tearing and splintering. The result is clean caps that look professional and hold securely.

Versatile across materials and machines

Designed for hardwoods, softwoods, plywood, and MDF, this kit performs with hand drills, drill presses, and power drivers. For the smoothest plugs, bench drills can be ideal in a stationary setup.

How to use with confidence

While outcomes depend on your material and technique, this TEWORDA set aims to streamline your workflow and improve consistency across steps—from drilling and countersinking to plugging and fastening.
