    Product Description

  • Irwin 10231 Unibit® #1 13-step 1/4-inch step drill bit, 1/32-inch steps (1/8 - 1/2") save time by eliminating the need to change drills when drilling round holes in thin materials.
  • Each smaller size drill also acts as a pilot for the next size.
  • Patented single-flute cutting edge gives greater control through steps and a true round hole every time.
  • Ideal for drilling holes into thin materials such as stainless steel, copper, brass, aluminum, plastic and laminates.
  • Speedpoint tip penetrates faster than previous Unibit®s and prevents walking.
  • 3-flatted hex shank prevents slipping in drill chuck.
  • Drill diameters etched in flute for easy identification.
