IRWIN black oxide drill bits are built from M-2 high speed steel for strength, heat resistance and wear resistance. The 135° split point delivers true starts and minimizes bit walking, while the black oxide finish helps resist corrosion and improves chip evacuation. Straight shanks and drilling geometry across the range support secure chucking and efficient cutting; some variants include spiral flutes for enhanced chip removal. Suitable for general-purpose drilling in metals (including steel), wood and plastics, these bits are offered in single-piece and multi-piece pack options and various lengths to meet common drilling needs.
- for use in wood, metal, and plastic
- The 135 degree split point ensures a true start and eliminates bit walking
