Countersink Drill Bit Set, 5Pcs Adjustable Countersink Set for Woodworking

5Pcs Quick Change 1/4" Hex Shank Adjustable Countersink Drill Bit Set

Made of premium quality high-speed steel (HSS), this countersink drill bit set provides long-lasting cutting life. With these precision-machined bits, you can drill a pilot hole and countersink for the head of a screw or counterbore for a plug in a single step. The quick-change chucks are compatible with impact drills and other power tools designed to accept a 1/4" hex shank.

The 82° countersink angle matches the angle on the head of most screws, ensuring that all surfaces of the screw head make contact with the wood at the same time and with an equal amount of force. This eliminates the need to forcibly elongate the countersink by overdriving the screw.

Doubled Tool Life The 5pcs of free, replaceable drill bits in this set are depth-adjustable and removable for easy cleaning and replacement. Worn-out or blunt drill bits can be easily and readily replaced, extending the overall lifespan of the set.

One L-Wrench Hex Screw The included L-wrench hex screw provides better fixation of the drill bits, preventing dislodgement or falling off during use.
