RUKO SPB-DIN338-HSS-TiN-Ø1,1mm kierrepora

Precision twist drill bit with 1.1 mm diameter, ground from solid HSS and coated with titanium nitride for high wear resistance and extended tool life. The TiN coating reduces friction and heat buildup, making it ideal for drilling steel, cast iron, non-ferrous metals, and plastics.

Advantages

Ground from solid for excellent concentricity and accuracy. TiN coating increases surface hardness to approx. 2300 HV and withstands temperatures up to 600 °C. Complies with DIN 338 for consistent geometry and performance.

Suitable for

• Alloyed and unalloyed steel
• Cast iron
• Non-ferrous metals
• Plastics
