Precision IRWIN drill bit with a 3.2 mm diameter and titanium nitride (TiN) coating for fast, clean drilling in metal. Delivers long service life, reduced friction, and higher drilling speed thanks to a ground 135° tip and industrial flute for efficient chip evacuation.
The IRWIN HSS TiN 3.2 mm metal drill bit is designed for precise and efficient drilling in metallic materials. The ground 135° split point ensures perfect centering and requires less feed pressure, while the ground flute provides rapid chip removal. The titanium nitride (TiN) coating offers up to 6× longer life compared to standard HSS bits with black oxide finish.
Thanks to its hardness of approx. 80 HRC and low friction, you can drill at higher speeds and feed rates with less heat generation. TiN’s lower thermal conductivity directs heat into the chips and coolant rather than the bit, improving process stability and hole quality.
- Faster work: increase spindle speed by 40–60% and feed by 10–20%.
- Durability and efficiency: hard, wear-resistant TiN coating for longer life.
- Precision: 135° tip for clean starts without walking.
- Versatile use: ideal for drilling steel and other metals in rotary mode.
