Professional IRWIN HSS metal drill bit with titanium nitride (TiN) coating, diameter 3.0 mm, offers high wear resistance, faster drilling, and accurate centering thanks to a 135° tip. Ideal for rotary drilling in metals with up to 6× longer service life compared to standard HSS drill bits.
The IRWIN HSS TiN 3.0 mm drill bit is designed for efficient and precise drilling in metals. Thanks to its ground 135° tip, it self-centers easily and requires less feed pressure. The industrially ground flute ensures fast chip removal, increasing both work speed and hole quality.
The titanium nitride (TiN) coating with a hardness of approximately 80 HRC significantly reduces friction, limits heat buildup, and extends tool life by up to six times compared to standard HSS drill bits with a black oxide finish. It allows spindle speed to be increased by 40–60% and feed by 10–20% without a significant reduction in service life.
- Precision and speed: 135° tip for clean and accurate starting without chatter.
- Long service life: TiN coating resistant to heat and wear.
- Efficient chip evacuation: industrial-grade ground flute.
- Energy savings: low friction coefficient reduces heating and energy consumption.
