Irwin HSS TCT Drill Bit – 10502619

This 2.5mm Irwin HSS TCT drill bit offers versatility for detailed drilling work in hardened materials. The 2.5mm diameter is particularly useful for small fastener holes and precision engineering applications where you need to work with hardened steel, cast iron, or bronze alloys. The tungsten carbide tip is specifically designed to handle materials up to 50 Rockwell C hardness, whilst the four-facetted ground design ensures low drilling pressure and exceptional centring accuracy. This is crucial at 2.5mm diameter where maintaining alignment is essential for clean, accurate holes. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, delivers the strength and rigidity required for demanding industrial applications. When using this 2.5mm bit with stationary drilling equipment, always apply a 3-6% coolant emulsion as recommended by Irwin to enhance performance and significantly extend the drill bit's operational life.
