Description
Version:
The distinctive and aggressive centre point permits active centring and optimum guidance during the drilling operation. Innovative head design with short straight lands for significantly faster drilling coupled with significantly improved stability, even in reinforced concrete. Vibration-optimised helical profile with reinforced core. The core diameter and the helix pitch of the drill are precisely matched to each other and ensure efficient transmission of force from the hammer drill to the carbide tip.
Advantage:
- Short helical lands and concave rake faces (scooping effect) ensure smooth evacuation of the drilling dust.
- Wear marks: for evaluation whether the tool is still suitable for drilling holes suitable for insertion of plugs.
- Additional specially shaped core cutting edges: efficient fragmentation of concrete.
Application:
For drilling concrete, natural stone, and masonry - with very high drilling comfort.
