HSS TCT Drill Bit 7.5mm Pack 1

This 7.5mm Irwin HSS TCT drill bit provides excellent drilling capability at a useful intermediate diameter for hardened materials. The 7.5mm size is particularly valuable for specific clearance requirements and applications where standard 7mm or 8mm sizes don't provide the exact fit needed. The C2 tungsten carbide tip is specifically engineered to drill through hardened steel, cast iron, bronze alloys, and manganese alloyed steel, handling materials up to 50 Rockwell C hardness with precision. The four-facetted ground tip ensures excellent centring from initial contact, whilst the reduced drilling pressure design makes operation smoother and more efficient. The Chrome Vanadium Steel body is hardened to 56 Rockwell C, providing the rigidity and wear resistance essential for professional drilling in hard materials. Designed for stationary machine applications, this 7.5mm drill bit performs optimally when used with a 3-6% coolant emulsion as recommended by Irwin. The coolant is crucial for maintaining cutting efficiency and maximising the operational life of the carbide cutting edge.
