RUKO SPB-DIN338-HSS-TiN σπειροειδές τρυπάνι 6,2 mm

Twist drill bit with 6.2 mm diameter, made of high-speed steel (HSS) and coated with titanium nitride (TiN) for enhanced wear resistance and longer tool life. Conforms to DIN 338, ground from solid with a right-hand cutting direction and type N flute.

Advantages

The TiN coating reduces friction and increases surface hardness, allowing higher cutting speeds and improved chip evacuation. The precise point angle of 118° and h8 tolerance ensure accurate hole positioning and consistent diameter.

Suitable for

• Alloyed and unalloyed steel up to 900 N/mm² tensile strength
• Grey cast iron
• Malleable cast iron
• Non-ferrous metals
• Plastics
