Features
- Adapted for SDS-MAX Hammers
- Specially developed robust head geometry ensures that even the toughest applications can be mastered.
- Carbide Tip The optimal 4x90° carbide cutting edge symmetry prevents seizing upon hitting reinforcing steel.
- Fast Drilling Large, robust secondary cutters with dynamically curved cutting tips actively support the main carbide tip during fast drilling.
- Flute The drilling debris is transported fast in the large-volume flute geometry.
- Accuracy Centering point with 130° point angle ensures highly accurate, precise drilling and guarantees optimal drill guidance.
- The individual wear marking is an indicator for evaluating the dimensional stability of the anchor holes.
- Impact Energy The reinforced-core flute achieves the optimum between volume and break resistance.
- Vibrations are dampened and resulting in more impact energy on the carbide tip.
