Description
Version:
Same as No. 114004.
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.
With special cutter geometry also for use in stainless steels.
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.
With special cutter geometry also for use in stainless steels.
Recommendation:
Maximum drilling depth:
L2 = LC - 1.5 × DC.
L2 = LC - 1.5 × DC.
Note:
Drills with plain shank, without drive flat.
