FTG USA 5-Pc Adjustable Wood Countersink Drill Bit Set (#4–#12) with Tapered Bits

Overview

Meet the FTG USA Adjustable Wood Countersink Drill Bit Set, a compact 5-piece kit designed for consistent countersinking and clean screw seating across a range of wood types. Each countersink bit is secured with a fixed pin and a 1/4" hex shank, with sizes spanning #4 (7/64") through #12 (7/32"). Two depth-stop collars—3/8" and 1/2"—let you lock in precise drilling depths for repeatable results.

Why this set stands out

• Five countersink bits: #4, #6, #8, #10, #12; covers a spectrum of screw sizes and countersink depths
• Depth stop collars provide consistent depth control to reduce guesswork in assemblies
• Replacement tapered bits available to extend tool life and maintain a sharp bite
• 82-degree counter bore chamfer for smooth, uniform countersinking in both hard and soft woods
• Quality HSS M2 Grade 6542 steel with a wider flute design to improve chip flow
• Drill, countersink, and counter-bore in one step, streamlining workpieces and reducing setup time

The kit combines practical design with durable engineering. A compact arrangement supports quick bit changes, while the tool geometry aims for clean holes and precise screw seating, helping projects feel orderly from the first screw in.

Real-world use cases

• Furniture assembly and cabinetry where flush screw heads matter
• Edge treatments and hidden fasteners on softwoods and hardwoods
• Pilot holes that help minimize wood splitting during installation
• Prototyping and hobby projects that benefit from repeatable depth control
