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, For use in concrete, masonry, natural stone, granite
Highest drill speed thanks to reduction in friction and improved impact transmission. The special cutting geometry on the chisel-shaped drill head ensures deep penetration in hardest concrete and granite Stable and durable centring point for high-precision spot-drilling, no running across smooth surfaces 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., 2-spiral helix with its large geometry with reinforced core (KVS). Quick delivery of bore dust, reduces friction in drilled hole and improves the vibration behaviour. The narrower cutting width geometry at the front edge and the reinforced relief and core at the rear additionally reduce friction whilst ensuring high resistance to breakage at the same time For use in concrete, masonry, natural stone, granite
