Professional IRWIN metal drill bit with titanium nitride (TiN) coating for fast, clean, and precise drilling. Sharp 135° tip for easy centering, higher resistance to heat and friction, and up to 6× longer service life compared to standard HSS drill bits.
The IRWIN HSS metal drill bit with TiN coating is designed for demanding use in workshops and industry. The ground 135° tip ensures precise starting without wandering and requires less pressure when drilling. The industrially ground flute guarantees fast chip evacuation and smooth workflow.
The titanium nitride (TiN) coating with hardness approx. 80 HRC significantly reduces wear and friction, giving the drill bit up to 6× longer life than standard black-oxide drill bits. TiN allows increasing speed by 40–60% and feed by 10–20% without a significant reduction in tool life. TiN’s poor thermal conductivity transfers more heat into the chips and coolant, protecting the drill bit itself.
