RUKO SPB-DIN338-HSS-TiN σπειροειδές τρυπάνι 8,25 mm

The RUKO SPB-DIN338-HSS-TiN twist drill bit delivers precision drilling in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics. Its TiN coating reduces friction and increases wear resistance, while the ground-from-solid HSS body ensures accurate holes.

Highlights

• Titanium nitride (TiN) coating for extended tool life
• Precision ground from solid HSS for high accuracy
• DIN 338 standard with 118° point angle for general-purpose drilling
• Cylindrical shank for secure chuck grip

In daily use

With an 8.25 mm diameter and 75 mm flute length, this drill bit handles deep-hole drilling in metal and plastic. The right-hand cutting geometry clears chips efficiently, and the gold TiN surface reduces heat buildup.
