The Ruko-235121 tap set is designed for creating through and blind hole threads in a variety of materials, including unalloyed steels, low-alloy steels with a tensile strength of up to 800 N/mm², malleable cast iron, and non-ferrous metals. This set allows for an efficient threading process, as the thread is tapped in two steps, guaranteeing a precise and high-quality finish. The set includes two pieces: a roughing tap and a finishing tap, ensuring optimal performance in creating fine metric threads according to DIN ISO 13. The thread tolerance is ISO 2/6H, providing a suitable and reliable fit in industrial applications. ferrous
