This 3.5mm Irwin HSS TCT drill bit provides excellent capability for drilling hardened materials where slightly larger hole sizes are required. The 3.5mm diameter is commonly used in mechanical assembly work and for creating clearance holes in hardened steel components. The C2 tungsten carbide tip is engineered to drill through materials up to 50 Rockwell C hardness, including hardened steel, cast iron, bronze alloys, and manganese alloyed steel. The four-facetted ground design delivers two key advantages: it reduces the drilling pressure needed, making the operation smoother, and ensures perfect centring for accurate hole placement. The drill bit's body is manufactured from Chrome Vanadium Steel and hardened to 56 Rockwell C for exceptional strength and longevity. This 3.5mm bit is designed for stationary machine use, and should always be operated with a 3-6% coolant emulsion as recommended by Irwin to maximise performance and extend the service life of the cutting edge.
