About this item
- Nitride-Coated, Built To Last: Made of 4241 high-speed steel with an industrial black-nitride coating, these twist drill bits run cooler, resist wear and corrosion, and hold an edge far longer than ordinary black-oxide bits, so you replace them less.
- Won't Snap Or Separate: A precision press-fit pin locks the bit body and 1/4" hex shank into one rigid piece. Unlike brazed bits, it resists shank fracture and separation under high impact-driver torque, for fewer snapped bits mid-job.
- Starts Clean, No Walking: The sharp 118° precision-ground point bites on contact and self-centers without a pilot hole, so bits don't skip or wander. Fully ground spiral flutes clear chips fast and shed heat for smooth, burr-free holes.
- 1/4 Hex Quick Change: The standard 1/4" hex shank snaps into any quick-change chuck in one move, no key and no slipping. It fits cordless drills, drill drivers and impact drivers, so you swap sizes in seconds.
- 13 Sizes, Indexed Case: You get 13 fractional sizes from 1/16" to 1/4", each held in a labeled indexed case for fast pickup and no lost bits. Drills wood, thin sheet metal, aluminum and plastic, ideal for DIY, repairs and assembly.
