Adjustable Countersink Drill Bit Set with Replaceable Bits and Hex Wrench for Woodworking

Adjustable countersink drill bit set with 1/4" hex shank, made of premium quality high-speed steel (HSS) for long cutting life. Achieve pilot holes and countersinks for screws or counterbores for plugs in one easy step with precision machining and quick-change chucks. Designed to work with impact drills and other power tools that accept a 1/4'' hex shank.

The 82° countersink angle matches the most common screw head angles, ensuring all surfaces of the screw head make contact with the wood simultaneously and with equal force. This eliminates the need to overdrive the screw to elongate the countersink. The set includes 5 replaceable drill bits that are depth-adjustable and removable for easy cleaning and replacement.

Constructed from high-speed steel with a hardness of HRC 62-64, these bits provide superior cutting power, durability, and abrasion resistance. The convenient 1/4'' hex shanks allow for quick changes and are compatible with most household drills. Ideal for woodworking projects on various materials such as wood, plastic, PVC, fiberboard, particleboard, plywood, and rubber.

Packaged in a plastic case for easy storage and organization, this multi-purpose set is suitable for both home and professional use.
