Countersink Drill Bit Set, 5Pcs Quick Change Adjustable Bits for Woodworking

The 5Pcs Quick Change 1/4" Hex Shank Adjustable Countersink Drill Bit Set is made of premium quality high-speed steel (HSS), providing long-lasting cutting performance. This versatile set allows you to drill a pilot hole and countersink for the head of a screw or counterbore for a plug in a single step.

The precision-machined quick-change chucks on these bits 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 common screws, ensuring the entire surface of the screw head makes full contact with the wood with equal force. This eliminates the need to forcefully elongate the countersink by over-driving the screw.

For added convenience and longevity, 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 readily replaced, extending the overall tool life. The set also includes a handy L-wrench hex screw for better fixation of the drill bits, preventing dislodgement or accidental loss.

Crafted from premium high-speed steel with an excellent hardness of HRC 62-64, these countersink bits provide superior cutting power, high durability, and good abrasion resistance. The size of the pilot holes they create is perfect for #5, #6, #8, #10, or #12 screws.

The 82° angle of these countersink bits is designed to match the most commonly used woodworking screws, ensuring a seamless and professional-looking finish for your projects. The 1/4" hex shank allows for quick and easy changes between the bits, making them compatible with a wide range of impact drills and other power tools.

This versatile countersink drill bit set is suitable for a variety of home and professional woodworking projects, including work on wood, plastic, PVC, fiberboard, particleboard, plywood, and rubber. With the ability to drill, countersink, and counterbore in a single step, this set streamlines your workflow and saves time.

For your peace of mind, the countersink bits are packaged in a durable plastic case for easy organization and storage. Should you have any issues with your purchase, the manufacturer offers a satisfaction guarantee, with the option to request a refund or replacement to ensure your complete satisfaction.
