Description
Version:
Drill head with square cross-section. 4×90° geometry with specially developed equal height tips and stable shoulders ensure precisely dimensioned holes for professional setting of anchors and secure plug attachment. 4-flute drilling heads for smooth drilling with low vibration and optimum guidance in the drilled hole. Radially shaped reinforced protection: protects the engagement of the reinforcements and increases the working life.
Advantage:
- Short spiral starts ensure a smooth evacuation of the drill dust.
- Wear marks: for evaluation whether the tool is still suitable for drilling holes suitable for insertion of plugs.
- 4×4 design permits a precise radial run-out and minimise wear and loss of frictional grip.
Application:
For drilling concrete, natural stone, and masonry − with very high drilling comfort.
