RUKO SPB-DIN338-HSS-TiN Ø8,1mm σπειροειδές τρυπάνι

Twist drill bit with 8.1 mm diameter, made of high-speed steel (HSS) and coated with titanium nitride (TiN) for enhanced durability and reduced friction. The gold-coloured TiN coating improves heat resistance and chip removal, making it suitable for drilling steel, cast iron, non-ferrous metals, and plastics.

Advantages

TiN coating extends tool life and allows higher cutting speeds. Ground from solid with a 118° point angle and cylindrical shank for precise centring and smooth drilling. Right-hand cutting direction with h8 tolerance for consistent hole quality.
