  • Shank: Reduced 3/8" with 3-flat drive
  • Material: HSS (High-Speed Steel)
  • Coating: Black & Gold finish

Features

  • 3-flat shank design improves grip and torque transfer in standard chucks, reducing cam-out during heavy cuts.
  • Black & Gold coating delivers lower friction and increased wear resistance for repeated metal drilling.
  • HSS core provides reliable performance when drilling through metals such as mild steel, cast iron, and certain aluminum alloys.
  • Large-diameter cutting portion (39/64") with a reduced 3/8" shank increases versatility for tasks that require a larger hole while using a common shank size.
  • Ideal for metalworking projects requiring precise 39/64" holes; apply appropriate feeds and speeds for HSS drilling in metal.
  • Use cases include fabrication, automotive maintenance, and shop tasks where a robust, single-piece drill bit is preferred.
