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 professional drilling operations. Designed for stationary machine applications, this 5.5mm drill bit achieves best results when used with a 3-6% coolant emulsion as recommended by Irwin. The coolant is crucial for maintaining optimal cutting performance and maximising the service life of the carbide cutting edge. Features and Benefits: • 5.5mm diameter for intermediate sizing requirements • C2 carbide tip for materials up to 50 Rockwell C • Four-facetted grind for perfect centring • Chrome Vanadium Steel hardened to 56 Rockwell C • Pack of 1 Specifications: Tip Diameter (mm): 5.5 Working Length (mm): 57 Overall Length (mm): 93 Pack Qty.: 1 Diameter: 5.5mm. Total length: 93mm.
