RUKO SPB-DIN338-HSS-TiAlN Broca helicoidal 4,5 mm

The RUKO SPB-DIN338-HSS-TiAlN twist drill bit stands apart through its TiAlN coating and split point geometry. Unlike standard uncoated bits, this tool is optimized for dry machining and high-temperature applications, delivering reliable performance across alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics.

Highlights

• TiAlN coating for high hardness and heat resistance
• Split point (cross-ground) for accurate starting without center punch
• Ground from solid HSS for consistent quality
• Right-hand cutting, cylindrical shank
• DIN 338 standard dimensions: 80 mm overall length, 47 mm flute length

In daily use

The 130° point angle and split point design reduce walking and improve centering, making this bit suitable for precise drilling in demanding materials. The TiAlN coating extends tool life and allows higher cutting speeds, especially in dry conditions.
