» The 3-surface-shank provides an excellent fixing within the drill chuck with little effort. In addition, the shank ensures an ideal power transmission. No spinning of the drill!
» The 135º high performance cutting edge ensures a very high aligned preciseness, particularly when hand-operated with a cordless drilling machine. The edge prevents sliding off corrugated surfaces whilst spot-drilling.
» Increased wear resistance of the rechargeable battery due to reduction of cutting forces.
» The black bevel increases the wear resistance and prevents cold welding and build-up edges.
» The 40º helix angle enables a perfect and fast chip removal and provides a high cutting speed along with increased stability and accuracy.
Heavy-duty high speed steel with 5 % cobalt content.
High ductility and heat resistance, for drilling holes in difficult-to-machine materials with a strength of up to 1100 N/mm².
