RUKO SPB-DIN338-HSS-TiN Twist Drill Bit 3/8 Inch (9.5 mm) TiN Coated

This RUKO twist drill bit stands out with its titanium nitride (TiN) coating, which reduces friction and extends tool life when drilling in steel, cast iron, non-ferrous metals, plastics, and wood. The gold-colored surface also makes it easy to identify among uncoated HSS bits.

Highlights

• TiN coating for improved wear resistance and lower friction
• Ground from solid HSS for precise concentricity and sharp cutting edges
• DIN 338 standard with 118° point angle for general-purpose drilling
• Right-hand cutting direction with cylindrical shank for standard drill chucks
• Diameter 3/8 inch (9.5 mm) with h8 tolerance for accurate holes

In daily use

The 125 mm overall length and 81 mm flute length provide good chip evacuation and reach. The TiN coating helps prevent built-up edge, especially in tougher steels, and the gold finish makes the bit easy to spot in a tool box. Suitable for hand drills and drill presses.
