Irwin HSS TCT Drill Bit

This 14mm Irwin HSS TCT drill bit is the largest size in the range, designed for substantial drilling operations in hardened materials. The 14mm diameter is ideal for heavy-duty structural applications, large mounting systems, and industrial fabrication work where you need to create significant holes through hardened steel, cast iron, and bronze alloys. Equipped with a C2 tungsten carbide tip, this drill bit excels at penetrating materials up to 50 Rockwell C hardness, providing reliable performance in the most demanding conditions. The four-facetted ground tip ensures excellent centring accuracy, which is crucial at this larger diameter for maintaining precision under substantial drilling forces. The reduced drilling pressure design makes operation more efficient and controlled. The Chrome Vanadium Steel body is hardened to 56 Rockwell C, delivering exceptional strength, rigidity, and wear resistance for heavy-duty applications. This 14mm bit is designed for use with stationary drilling machines and achieves best results when operated with a 3-6% coolant emulsion as recommended by Irwin. The coolant application is essential for maintaining cutting performance and maximising the operational life of the drill bit.
