The new GT500 twist drill has been especially designed for the machining of high tensile steels and is produced in highly efficient PM-steel. By combining the advantages of high speed steel drills with those of solid carbide drills, it closes the gap that has existed for the machining of medium tensile steels and medium batch sizes.
High heat-resistant drill with wide chip space. Suitable for drilling alloyed and unalloyed steel and casting with tensile strengths of over 800 N/mm2. Particularly suitable for drilling hot and cold-rolled steels, anti-friction bearing steel, high alloyed steels as well as case hardening and heat-treatable steels. Well suited for drilling depths greater than 3 x D (nitrided lands and wide flutes).
