The three-area shank provides for an excellent fixing in the drill chuck with low effort. In addition, the shaft provides for an optimum power transmission. No twisting of the drill! The 135º high-performance cutting edge ensures very high centering accuracy, especially in handheld applications with the cordless drill driver. The blade prevents slipping when drilling on curved surfaces. Increased battery life by reducing cutting forces. The black chamfer increases the wear resistance and prevents cold welding and body cutting. The 40º twist angle enables a perfect and fast chip removal and provides for high cutting speeds with increased stability and accuracy.
