Twist drill DIN 338 type UNI, HSSE-Co 5
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.
