RUKO Helical Drill Set 25PCS. DIN 338 TI- High performance twist drill for all-purpose use in drilling machines and cordless drills. (Materials up to 5,0 mm thickness)
- 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.
HSSE-Co 5:
- Heavy-duty high speed steel with 5 % cobalt content.
