This 6.5mm Irwin HSS TCT drill bit offers precision drilling capability at an intermediate diameter, ideal for specific engineering applications in hardened materials. The 6.5mm size provides the exact clearance needed when standard sizes don't meet your tolerance requirements, particularly in precision engineering and assembly work. The C2 tungsten carbide tip is engineered to handle the toughest drilling challenges, penetrating hardened steel, cast iron, bronze alloys, and manganese alloyed steel up to 50 Rockwell C hardness. The four-facetted ground design ensures perfect centring accuracy, which is essential for maintaining tight tolerances, whilst also reducing the drilling pressure required for smoother operation. The Chrome Vanadium Steel body is hardened to 56 Rockwell C, delivering the strength and rigidity needed for professional applications. Designed for stationary machine use, this 6.5mm drill bit achieves optimal performance when operated with a 3-6% coolant emulsion as recommended by Irwin. This coolant application is essential for maintaining cutting efficiency and significantly extending the operational life of the drill bit.
