Countersink Drill Bit Set 7-Piece Hex Shank 82 Degree 5-Flute, Carbide-Tipped for Wood and Metal, Impact Driver Compatible

1.Impact-Ready Hex Lock Design — Dual set-screws lock the bit into impact driver chucks with zero wobble under peak torque. The 1/4 inch hex shank with reinforced collar stays firmly seated through hundreds of fasteners, unlike standard round-shank countersinks that spin loose. 2.Carbide-Tipped StaySharp Edge — Premium tungsten carbide tipped bits resist heat and friction, maintaining a sharp edge through 3 times more countersinks than standard HSS. The 5-flute design reduces vibration for cleaner, more consistent holes. 3.One-Action Drill, Countersink, and Counterbore — Each bit drills the pilot hole, countersinks the screw head, and counterbores for a plug in one step. No bit changes, no depth guessing. The 82 degree angle matches standard wood screws for flush installations. 4.7 Sizes Cover Number 6 to Number 16 Screws — Includes the most commonly used countersink sizes for cabinetry, furniture, decking, and general woodworking. Each bit is laser-marked with its screw size for fast identification without measuring. 5.90-Day Edge Guarantee — If any bit dulls or chips within 90 days of normal use, we ship a replacement free with no return required.
