VERSATILE DESIGN & ADJUSTABLE DEPTH CONTROL: Combines a center tooth drill bit, cutting edge kni-fe teeth, and removable depth limiter. The M10-threaded hex shank ensures secure compatibility with drills/impact drivers. The adjustable limit piece prevents over-drilling, ideal for precise hole sizing in woodworking projects. HIGH-DURABILITY MATERIAL & ANTI-CORROSION COATING: Features bla-de-hardened teeth for long-lasting sharpness and wear resistance. Coated with rust-preventive oil to resist corrosion from moisture or repeated use. Ideal for indoor/outdoor woodworking, maintaining edge integrity for years. ANTI-SLIP HEX SHANK: Textured black hex shank provides a non-slip grip on drills, reducing slippage during high-torque operations. The reinforced steel body withstands heavy-duty use, while ergonomic design minimizes hand fatigue during extended projects. 3-TOOTH TECHNOLOGY FOR FASTER DRILLING: Center tooth initiates precise entry into wood, while sharp kn-ife-edge bla-des accelerate cutting efficiency. Triple structure reduces jamming and heat buildup, smoothly penetrating hardwoods (e.g., oak) and softwoods (e.g., pine).
