Countersink Drill Bit Set #8 (11/64ft) Tapered Wood Bits - Adjustable

Our review of the FTG USA 12 Pc #8 (11/64') Countersink Drill Bit Set finds it best suited for woodworkers who need a reliable, adjustable countersink that combines pilot drilling, countersinking and counterboring in one step. The set's single-size focus makes it ideal for repeat tasks with #8 screws, and the most convincing reason to buy is the depth-adjustable tapered bit design that creates clean, tight screw holes while reducing splitting in both soft and hard woods.

Key Features

• Adjustable depth: Two depth stop collars and hex screws let the user control pilot depth precisely for consistent, repeatable countersinks.
• Tapered 11/64' pilot: The pointed tapered pilot drills fast, creates a secure fit for #8 screws, and helps prevent wood splitting during installation.
• Four-flute countersink cutter: The wider flute shape and four-flute #45 carbon steel cutter clear chips efficiently for cleaner holes.
• Quick-change 1/4' hex shank: The hex shank fits common chucks and quick-change holders for fast bit swaps on the job.
• Durable case and replaceable bits: A compact plastic case stores 12 identical bits, two hex wrenches and spare tapered bits for extended life and easy organization.
• Versatile single-size set: The set is optimized for screws size #8 and includes counter-bore and plugs sized 3/8' for a finished look.

Who It's For

This countersink set is a good match for hobbyist and professional woodworkers who frequently drive #8 screws and want a single, reliable solution for pilot drilling and countersinking in one operation. It is particularly useful when building furniture or cabinetry where consistent screw fit and a neat finish matter.

Those who need multiple screw sizes in one kit, or who rarely use #8 screws, should look elsewhere; this set deliberately focuses on one size to deliver repeatable results rather than covering a wide range of screw diameters.
