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