RUKO SPB-DIN1897-HSSCo-Ø11,0mm kierrepora lyhyt malli

The RUKO SPB-DIN1897-HSSCo-Ø11.0mm is a short series twist drill bit engineered for precision and durability in metalworking. Its HSS-Co construction with 5% cobalt enhances heat resistance, making it suitable for drilling stainless and acid-resistant steels, while the split point grind reduces walking and improves centring accuracy.

Highlights

• HSS-Co with 5% cobalt for high heat resistance
• Split point (cross-ground) for precise starting without centre punch
• DIN 1897 short series for increased rigidity
• Fully ground with bright finish for smooth chip evacuation
• Right-hand cutting, cylindrical shank

In daily use

This drill bit excels in industrial drilling of alloyed and unalloyed steel, stainless steel (V2A/V4A), cast iron, and non-ferrous metals. The 130° point angle and h8 tolerance ensure accurate holes, while the short flute length provides stability in demanding applications.
