Description

Version:

Chamfers are nitrided. Particularly sturdy and robust due to the strengthened core diameter. Ground flutes, with high concentricity. Precision ground point. Three drive flats on the shank for use in a 3-jaw chuck.
  • Ideal for producing precise holes in sheet metal, pipes, and profiles.
  • Reliable spot drilling without centring or centre punching – even on curved surfaces – thanks to innovative ground point.
  • Oblique drilling possible without any problems after the first level of the drill tip has penetrated the material.
  • Drilling with significantly less force required than with conventional DIN338 HSS drills – up to a diameter of 13 mm directly in the cordless drill/driver.
  • Stable and secure form fit in the 3-jaw chuck.
  • General use across a wide spectrum of materials including plastic, wood and acrylic without tearing or splintering.
  • The drill does not rattle or dig in – even in the case of thin-walled materials.
  • Burr-free drill exit.
  • Ideal for drilling out bolts and rivets.

Recommendation:

Maximum drilling depth:
L2 = LC - 1.5 × DC.
