RUKO SPB-DIN338-HSS-TiN broca helicoidal 11,5 mm

The RUKO SPB-DIN338-HSS-TiN Ø11.5 mm is a precision-ground twist drill bit built to DIN 338, featuring a titanium nitride coating that reduces friction and increases surface hardness for longer life. Unlike standard uncoated bits, the gold TiN layer allows higher cutting speeds and provides better chip evacuation in tough materials.

Highlights

• DIN 338 standard geometry with 118° point angle and type N helix
• Titanium nitride (TiN) coating for wear resistance and reduced friction
• Ground from solid HSS for consistent precision and strength
• Cylindrical shank with h8 tolerance for secure chuck grip
• Suitable for steel, cast iron, non-ferrous metals, and plastics

In daily use

This drill bit is a dependable choice for workshops and demanding drilling tasks. The TiN coating keeps the cutting edges sharp longer, while the standard helix angle ensures efficient chip removal. The 11.5 mm diameter and 142 mm overall length provide good reach, and the 94 mm flute length allows deep holes without frequent clearing.
