RUKO SPB-DIN338-HSS-TiN-Ø14,5mm kierrepora

The RUKO SPB-DIN338-HSS-TiN Ø14.5 mm twist drill bit is a precision-ground tool engineered for demanding metalworking tasks. Unlike standard HSS bits, its TiN coating reduces friction and heat, extending tool life and improving hole quality in alloyed and non-alloyed steels, cast iron, and non-ferrous metals.

Highlights

• DIN 338 standard with type N flute profile for reliable chip evacuation
• 135° split point for accurate self-centering without a pilot hole
• Ground from solid HSS with TiN coating for high wear resistance
• Cylindrical shank with h8 tolerance for secure chuck grip

In daily use

This drill bit is suited for stationary drilling machines and powerful hand drills. The split point minimises walking on the workpiece, while the TiN coating keeps the cutting edge cool during continuous operation. It works effectively on steel, cast iron, non-ferrous metals, and plastics.
