IRWIN HSS TiN drill bits with a 2.5 mm diameter are ideal for precise drilling in metals using a rotary drilling method. Thanks to the sharp 135° point, the bit self-centers easily and requires less pressure, increasing accuracy and working comfort. The titanium nitride (TiN) coating with hardness up to 80 HRC significantly increases wear resistance and reduces friction.
Faster work and longer life: the industrial-grade ground flute ensures efficient chip evacuation, lower heat buildup, and smooth drilling. Thanks to the TiN coating, you can increase spindle speed by 40–60% and feed by 10–20% without a significant reduction in service life. The lower thermal conductivity of the coating transfers more heat into the chips and coolant, thereby protecting the drill bit itself.
