High-Speed Steel Drill Bit Set for Non-Slip Metal and Wood Drilling

The Bosch BL14 14-Piece Black Oxide Drill Bit Set is a professional jobber-length cutting kit engineered for general-purpose drilling in light-gauge metal, wood, and composite plastics. Fabricated from industrial high-speed steel with a heat-resistant black oxide coating, these bits minimize friction to extend operational life during continuous high-torque applications. The integrated 135-degree split-point tip on sizes 1/8-inch and larger forces immediate target engagement to eliminate bit walking or skating on polished steel surfaces. For enhanced safety and tool security, bits sized 3/16-inch and larger incorporate a three-flat shank layout that prevents spinning or slipping inside standard drill chucks.

Best Used For:

  • Metal Fabrication: Boring accurate pilot and clearance openings through thin-gauge steel sheet metal and aluminum framing profiles.
  • General Carpentry: Drilling clean holes in framing studs, heavy timber plates, and structural plywood assemblies.
  • Electrical and Mechanical Rough-Ins: Creating quick wire and fastener entries through PVC panels, junction boxes, and composite materials.

Key Performance & Safety Features

  • No-Skate Starts: Engineered 135-degree split-point tip provides immediate self-centering penetration without walking on contact.
  • Friction Mitigation: Industrial black oxide coating lowers operating temperatures to prolong high-speed steel longevity.
  • Three-Flat Shank Geometry: Integrated flats on sizes 3/16-inch and up ensure optimal torque transfer and prevent chuck slippage.
  • Comprehensive Assortment: Contains 14 distinct jobber bits covering high-demand sizing variations from 1/16-inch up to 1/2-inch configurations.
  • Rigid Protection: Includes a durable plastic storage case that keeps fractional increments organized and protected on active jobsites.

Pro-Tip: When drilling into light-gauge steel, apply a steady, moderate downforce and lower your drill speed. This technique combined with the black oxide coating prevents structural overheating and preserves the sharpness of the 135-degree split point.
