FTG USA 12 Pc #8 (11/64ft) Countersink Drill Bit Set - Adjustable

In this review of the FTG USA 12 Pc #8 (11/64') countersink drill bit set, the bottom line is simple: this kit is aimed at woodworkers and hobbyists who need a fast, repeatable way to drill pilot holes, countersink and counterbore in one step. The set's single biggest selling point is the adjustable tapered countersink bits with depth stop collars and a 1/4' hex shank that let users control pilot depth and create a neat 3/8' counterbore for screw heads; that combination makes it a practical choice for cabinet makers, deck builders and DIYers who value clean, consistent screw seating. Our review finds the set useful and affordable, though not without tradeoffs.

Key Features

• Adjustable depth: The included depth stop collars allow controlled pilot hole depth for consistent countersinking and screw fit-up each time.
• Tapered countersink design: The 82-degree tapered cutter creates smooth chamfers and proper seating for #6 screws without extra sanding.
• High speed steel construction: Made from HSS M2 grade steel for improved wear resistance and cutting retention in both hard and soft woods.
• Quick change hex shank: The 1/4' hex shank with securing pin fits common quick-change chucks for fast bit swaps during repetitive work.
• Wide flute: A wider flute profile increases chip flow for faster, cleaner drilling and fewer clogged holes.
• Convenient case: The plastic storage case keeps all 12 identical bits, two depth collars and two hex wrenches organized and protected on the job.

Who It's For

This set is best for woodworkers, carpenters and serious DIYers who often run many identical screw holes and want a repeatable countersink and counterbore in a single pass. It works well for tasks like building raised beds, installing trim or assembling wooden furniture where consistent screw seating matters.

People who need a variety of sizes, heavy industrial use, or absolute top-tier break resistance should look elsewhere or consider using the bits with lighter loads, since customers have reported occasional breakage under heavy or abusive use. This kit is optimized for volume and convenience rather than as a single premium replacement for every countersink need.

Pros & Cons

Pros

• Good value for money with a dozen identical bits plus collars and wrenches for quick setup.
• The adjustable depth collars and 82-degree tapered cutters deliver clean countersinks and consistent screw fit.
• HSS M2 construction and laser-printed branding help identify quality and maintain sharpness for general woodworking.

Cons

• Some users report durability issues and occasional bit breakage under heavy or improper use.
• The set includes only one size, so a different screw size requires a different kit.
