FEATURES
Multiple sizes for any job: This set includes four countersink drill bits in 7/64" x 3/8", 1/8" x 3/8", 9/64" x 3/8", and 5/32" x 3/10" sizes. It also comes with a hex wrench for quick bit changes and depth adjustments.

Adjustable depth control: Designed for precision woodworking, these countersink drill bits allow easy depth adjustment with the included hex wrench, helping create clean and accurate countersunk holes for different screw sizes and project needs.

Reduced wear and cleaner drilling: Featuring an upgraded auto-stop collar, each drill bit automatically stops when it touches the wood surface, helping prevent over-drilling, reduce wear, and improve drilling consistency and surface finish.

Four-flute cutter design for clean holes: This precision countersink set features four-flute HCS cutters and HSS pilot drill bits for reliable drilling performance. The spiral flute design quickly removes chips and debris, creating smoother holes while extending bit life.

Wide compatibility and versatile use: Suitable for wood, plywood, MDF, particle board, plastic, and drywall, these countersink bits feature a standard 82° countersink angle. The 1/4" hex shank works with most electric drills for DIY and professional use.

Used these for fitting cabinet hinges last weekend - the auto-stop collar saved me at least three botched attempts! Chips clear nicely but mind your drilling speed in hardwood. The included hex wrench is a bit naff though, already showing wear after a few adjustments. Overall decent for the price.

Honestly chuffed with this counterbore set! The depth stop is a proper game-changer - no more eyeballing measurements and ruining workpieces. The four-flute design cuts like butter through MDF, though I'd say the smaller sizes could do with a tad more sharpness out the box. Hex shank fits all my drills, which is brilliant.
