This 5.5mm Irwin HSS TCT drill bit provides versatile drilling capability in hardened materials at a useful intermediate size. The 5.5mm diameter is particularly valuable for specific clearance holes and applications requiring precise tolerances between standard 5mm and 6mm sizes. The tungsten carbide tip is specifically engineered to drill through hardened steel, cast iron, bronze alloys, and manganese alloyed steel, effectively handling materials up to 50 Rockwell C hardness. The four-facetted ground tip design ensures excellent centring accuracy from initial contact, whilst the reduced drilling pressure makes operation smoother and helps prevent tool deflection. The Chrome Vanadium Steel body is hardened to 56 Rockwell C, providing the rigidity and wear resistance essential for professi...
