RUKO SPB-DIN338-HSS-TiN Twist Drill Bit 10.5 mm

The RUKO SPB-DIN338-HSS-TiN twist drill bit in 10.5 mm diameter is a precision-ground tool for reliable drilling in steel, cast iron, non-ferrous metals, and plastics. Its TiN coating reduces friction and improves heat resistance, extending tool life compared to uncoated HSS bits.

Highlights

• DIN 338 standard dimensions for consistent performance
• Titanium nitride (TiN) coating for reduced wear and better chip flow
• Ground from solid HSS for high dimensional accuracy
• Right-hand cutting with 118° point angle for general-purpose drilling

In daily use

The cylindrical shank fits standard drill chucks and provides secure clamping. The 10.5 mm diameter is suitable for clearance holes for M10 bolts or for reaming to precise diameters. The TiN coating allows higher cutting speeds and feeds compared to uncoated HSS drills.
