RUKO SPB-DIN338-HSS-TiN τρυπάνι στριφτό 6,1 mm

Twist drill bit with titanium nitride coating for general-purpose drilling in steel, cast iron, non-ferrous metals, and plastics. The TiN coating increases surface hardness to approximately 2300 HV and provides heat resistance up to 600°C, extending tool life.

Advantages

Fully ground from high-speed steel (HSS) to DIN 338, with a cylindrical straight shank and 118° point angle. The gold-coloured TiN coating reduces friction and improves chip flow.

Suitable for

• Alloyed and unalloyed steel
• Grey cast iron
• Malleable cast iron
• Non-ferrous metals
• Plastics
