About this item

• 12-INCH EXTRA LONG DESIGN FOR DEEP DRILLING – With a full 12-inch (300mm) length and 9-inch drilling depth, this set easily tackles thick wood, beams, and through-holes. It solves the common problem where standard 6-8 inch bits are too short for deep or confined-space projects.
• PRECISE BRAD POINT & CLEAN HOLES – The unique triangular center tip (Brad Point) bites into wood immediately, preventing skidding and ensuring pinpoint accuracy. The specially ground cutting edges produce clean, splinter-free entry and exit holes, perfect for fine woodworking and furniture.
• 10 MOST-USED SIZES IN ONE SET – Covers essential diameters from 1/8” to 1/2” (1/8", 9/64", 5/32”, 11/64", 3/16", 7/32", 1/4", 5/16", 7/16", 1/2”). A complete collection for various tasks—from pilot holes to large dowel holes—saving you time from frequent bit changes.
• DURABLE CARBON STEEL & PERMANENT MARKS – Made of hardened carbon steel (HRC52) for lasting sharpness. Each bit features permanently laser-etched size markings that won’t rub off, eliminating the frustration of identifying worn, painted sizes.
• EFFICIENT CHIP REMOVAL & RUST PROTECTION – The optimized spiral flutes quickly eject wood chips, reducing heat buildup and bit jamming. A factory-applied anti-rust coating, paired with the included storage case, ensures long-term organization and bit life.
