Drill head design for increased durability, drilling speed and service life thanks to an aggressive head design with flat, wear-reducing cutting edges. The 160° cutting edge design of the drill head enables better spot drilling with increased resistance and durability. Core reinforcement and a hardened steel body ensure maximum load capacity and significantly increased breaking strength. Perfect grip and optimum power transmission from the machine to the drill bit are achieved by the optimised shank. The 2-stage helix effectively removes dust and improves drilling performance (from 6 mm diameter and 150 mm length).
