Achieve perfectly flush screw seats and clean, professional-looking joints with a precision countersink drill set designed to deliver consistent depth control and finished holes every time.
Durability is built in: pilot bits are made from M2 high-speed steel and countersinks from high-carbon steel, yielding sharpness that lasts through demanding tasks and repeated use.
Designed for precise, splinter-free drilling, each countersink features an 82-degree taper and three cutting edges. The set uses a universal 6.35 mm (1/4 inch) hex shank with an anti-slip groove, ensuring a firm grip in standard power tools and dependable performance on wood, plastic, and similar materials. Depth is adjustable via the included hex key so screws sit snugly and accurately.
Five sizes are included: 5, 6, 8, 10, and 12, offering the right countersink for each screw. The package contains five drill countersinks and one hex key for quick, precise depth changes. The pilot drills are M2 HSS and the countersinks are high-carbon steel for extended lifespan.

The 6.35 mm hex shank with a groove is compatible with most cordless screwdrivers and standard power tools, delivering slip-free performance.
