Irwin - hss tct Tip Drill Bit 3.0mm OL:61mm WL:33mm IRW10502620

General description This high-quality HSS TCT (Tungsten Carbide Tipped) drill bit is designed for precision drilling in hard materials. It is suitable for use on hardened steel, cast iron, bronze alloys, and manganese steel. The durable tungsten carbide tip can drill materials with a hardness up to 50 Rockwell C, ensuring excellent wear resistance and longevity. Its four-faceted ground tip provides perfect centering and reduces drilling pressure, resulting in faster and more accurate holes. The body is made from hardened chrome vanadium steel, offering robustness and resistance to wear. It is recommended for use with stationary machines and requires coolant to extend the tool's lifespan.
