RUKO SPB-DIN338-HSS-TiN spiraalipora 12,3 mm DIN 338 TiN-pinnoitettu

This RUKO twist drill bit stands out with its TiN coating, which reduces friction and improves heat resistance compared to uncoated HSS bits. The gold-colored surface also enhances wear resistance, making it a durable choice for general-purpose drilling in steel, cast iron, non-ferrous metals, and plastics.

Highlights

• Diameter: 12.3 mm
• TiN coating for reduced friction and longer life
