The three-face shank ensures an excellent hold in the drill chuck with low effort. The shank also ensures optimum power transmission. Drill bit does not spin freely!
The 135º high-performance cutting edge ensures very high centring accuracy, especially in hand-guided applications with the cordless drill driver. The cutting edge prevents slipping when beginning to drill curved surfaces.
Increased battery life by reducing cutting forces
The black chamfer increases wear resistance and prevents cold welding and edge build-up.
