The RUKO SPB-DIN338-HSS-TiN twist drill bit in 12.8 mm diameter stands out with its titanium nitride coating, which reduces friction and heat buildup, extending tool life and improving cutting performance in demanding metalworking tasks.

Highlights

• Precision ground from solid high-speed steel (HSS) for durability and accuracy
• Titanium nitride (TiN) coating for increased wear resistance and reduced friction
• DIN 338 standard with 135° split point for fast, self-centering starts
• Right-hand cutting with cylindrical shank for secure chuck grip

In daily use

This twist drill bit is suitable for drilling in alloyed and non-alloyed steel, cast iron, non-ferrous metals, and plastics. The split point design minimizes walking and eliminates the need for center punching, while the TiN coating allows higher cutting speeds and cooler operation.
