Product description:

  • For making holes in thin metal sheets
  • Titanium-nitride coated step drill with a surface hardness that makes the tool last 4 to 5 times longer than ordinary step drill bits. That same surface reduces friction, resulting in a tool that runs cooler and, in effect, self-lubricates whist running dry
  • Drills holes from 4 to 12 mm in 1 mm increments
  • Shank 1/4" (6 mm)
Key features according to our expert
  • Smallest diameter: 4 mm
  • Largest diameter: 12 mm
  • Shank size: 6 mm
