RUKO SPB-DIN338-HSS-TiN Twist Drill Bit 19/64 inch (7.54 mm) TiN Coated

Drilling precise holes in tough materials requires a bit that stays sharp and resists wear. The RUKO SPB-DIN338-HSS-TiN twist drill bit is engineered from high-speed steel with a titanium nitride coating, delivering high hardness and heat resistance for general-purpose drilling in steel, cast iron, non-ferrous metals, plastics, and wood.

Who is it for

This drill bit suits machinists, metalworkers, and serious DIYers who need reliable performance across a range of materials. Its 19/64 inch (7.54 mm) diameter is ideal for creating holes for bolts, screws, or clearance fits.

Main features

• TiN coating: gold-colored titanium nitride increases surface hardness to approx. 2300 HV and withstands temperatures up to 600°C, reducing friction and extending tool life.
• DIN 338 jobber length: standard proportions with 109 mm overall length and 69 mm flute length, suitable for most hand drills and drill presses.
• Ground from solid HSS: precise flute geometry with 118° point angle and right-hand cutting for efficient chip removal.
• Cylindrical shank with h8 tolerance: fits standard drill chucks securely.

Tips

Use cutting fluid when drilling steel to maximize bit life. For harder materials, reduce speed and apply steady pressure. Store in a dry place to preserve the TiN coating.
