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.
L2 = LC - 1.5 × DC.
Note:
Drill with plain shank and 3 drive flats.
