General description The Irwin HSS TCT Tip Drill Bit is engineered for precise drilling in hardened materials. It features a tungsten carbide tip for enhanced durability and efficiency, making it suitable for use with stationary drilling machines. This drill bit excels in drilling hardened steel, cast iron, bronze alloys, and manganese steel, providing accurate centering and requiring low drilling pressure due to its four-faceted ground tip. Technical specifications Diameter: 3.5mm Total length: 70mm Working length: 39mm Body material: Chrome Vanadium Steel, hardened to 56 Rockwell C Tip material: Tungsten Carbide Maximum hardness for drilling: 50 Rockwell C Compatibility and accessories Compatible with stationary drilling machines Recommended coolant: 3-6% emulsion for optimal performance and longevity Installation Insert the drill bit into the drill chuck, ensuring it is securely tightened Use appropriate safety equipment and follow standard drilling procedures Usage Use with

The Irwin Metric TCT (Tungsten Carbide Tipped) Drill Bits offer precision drilling with stationary machines in hardened steel cast iron bronze alloys and manganese alloyed steel. The C2 Carbide Tip will drill hardened material up to a hardness of 50 Rockwell C and is four facetted ground for low drilling pressure and perfect centring. The body of the drill bit is made from Chrome Vanadium Steel hardened to 56 Rockwell C. A coolant should always be used when drilling with TCT twist drill bits. Irwin suggest the use of a 3- 6% emulsion. The coolant will extend the lifetime of the drill bit.Irwin HSS TCT tip drill bit.
