USA MADE 1/4" HSS BLACK & GOLD JOBBER LENGTH DRILL BITS - 12 PACK

Made in the USA for demanding shop and production use, these 1/4" Black & Gold Jobber Length Drill Bits are precision-ground from solid, heat-treated M2 high-speed steel and hardened to HRC 64 for dependable cutting performance and wear resistance. The one-piece design delivers a durable, consistent cutting tool built for repeated drilling in steel, sheet metal, aluminum, PVC, MDF, oak, and maple.

A 135° split point helps the bit start accurately with less walking, while spiral flutes help carry chips out of the hole as you drill. The three-flat straight shank provides additional chuck engagement to help resist slipping under load, while the jobber-length design maintains a practical balance of reach and rigidity. The 12-pack keeps replacement 1/4" bits ready for fabrication, maintenance, production, and everyday shop work.
