Irwin HSS TCT Drill Bit

This 10.5mm Irwin HSS TCT drill bit offers precision drilling at a larger intermediate diameter for demanding applications in hardened materials. The 10.5mm size provides exact clearance when standard sizes don't meet your specific tolerance requirements, particularly in precision engineering and heavy-duty assembly work. The C2 tungsten carbide tip is specifically designed 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 ensures perfect centring accuracy, which becomes increasingly critical at larger diameters where any deviation would be more noticeable. The reduced drilling pressure design also makes operation more efficient and controlled. The Chrome Vanadium Steel body is hardened to 56 Rockwell C, providing exceptional strength and wear resistance. Designed for stationary machine use, this 10.5mm drill bit achieves optimal performance when operated with a 3-6% coolant emulsion as recommended by Irwin. The coolant is essential for maintaining cutting efficiency and significantly extending the operational life of the carbide cutting edge.
