Notice
  • When using the twist drill according to DIN 340, prior drilling of a centring bore is recommended. Our NC spotting drills (art. no. 063644 etc.) are perfectly suited to this.

  • Also recommended in conventional steel if longer service life compared to uncoated HSS drills is a priority.
