Noticeably quicker drilling

Optimum tip geometry and asymmetrically arranged grooves on the cutting edges ensure improved traction.

Optimum drilling performance with reinforced chamfers

Reinforced hard metal elements with noticeably larger reinforcement chamfers considerably reduce the possibility of the drill bit catching on reinforced chamfers and increase resistance.

Precise drilling

Due to special self-centring point.

Considerably improved drilling speed and dust removal while at the same time offering increased protection against breakage

Vario spiral conveyor with core reinforcement and back that narrows at the front and widens at the rear, as well as sharper angle at the spiral end ensures reduced friction, high stability and maximum transmission of impact energy.
