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 better spot drilling with increased durability and longevity. Core reinforcement and hardened steel body ensure maximum load capacity and significantly increased breaking strength. Perfect hold and optimum power transmission from the machine to the drill bit thanks to optimised shank. The 2-stage helix enables effective dust removal, which improves drilling performance (from 6 mm diameter and 150 mm length). Application examples: The extreme Dewalt 2 SDSPlus hammer drill bits offer top performance for continuous use in the hardest concrete, masonry, natural and artificial stone.
