RUKO SPB-DIN1897-11,0mm HSS-G lyhytpora DIN 1897

Precision-ground from solid HSS-G, this 11.0 mm stub drill bit delivers a 75 mm overall length and 46 mm flute length for exceptional rigidity in confined spaces. The bright, uncoated surface and 118° point angle ensure clean starts and efficient chip evacuation in steel, cast steel, grey cast iron, malleable cast iron, non-ferrous metals, and plastics.

Overview

Engineered to DIN 1897, this parallel-shank stub drill bit features a right-hand cutting direction and h8 tolerance for consistent hole sizing. Its short flute design minimizes deflection, making it ideal for precision drilling in tight setups where standard jobber drills are too long.

What stands out

• Short overall length (75 mm) for maximum stability and reduced vibration
• Ground from solid HSS-G for high wear resistance and long tool life
• Bright finish reduces friction and improves chip flow
• 118° point angle suitable for a wide range of materials
• Parallel shank with h8 tolerance fits standard drill chucks securely
