The IRWIN HSS TiN 5 mm metal drill bit is designed for demanding users who require reliability, precision, and durability. The titanium nitride (TiN) coating with a hardness of approx. 80 HRC significantly reduces wear, withstands high temperatures and friction, and extends service life by up to 6× compared to standard HSS drill bits.
Thanks to the 135° ground tip, the bit centers easily without slipping, and the ground flute in industrial quality ensures rapid chip removal. The low coefficient of friction enables higher speeds (by 40–60%) and greater feed rates (by 10–20%) without a significant reduction in service life. Heat is better conducted into the workpiece and coolant, increasing drilling process stability.
