Highest drill speed thanks to reduction in friction and improved impact transmission thanks to the special cutting geometry on the chisel-shaped drill head.
Stable and durable centering point for high-precision spot-drilling
Power breakers cause micro tears in the material for a noticeable quicker drill progress
The probability of snagging on concrete reinforcements is significantly reduced thanks to enlarged armouring phases.
The 2-spiral helix with its helical geometry with reincorced core ensures quick delivery of bore dust and maximum breakage resistance
