Overview
High-speed steel (HSS) step drill bits with a nitride coating, made for drilling holes of different sizes with a single bit. Choose a single 4-12mm, 4-20mm or 4-32mm bit, or a 3-piece set (with or without a carry bag).

Key Features

  • High-speed steel (HSS) construction
  • Nitride coating to reduce friction and run cooler

  • 4-20mm: 9 steps (4 to 20mm in 2mm increments)
  • 4-32mm: 15 steps (4 to 32mm in 2mm increments)
  • CE certified

Applications

Thin steel and iron plate, aluminum, insulation panels, PVC sheet and wood. Using water cooling can help extend bit life.
