Ideal for drilling hard-to-machine materials and for high demands. Suitable for processing unalloyed and alloyed steels (up to 1200 N/mm²), hot and cold work steels, as well as for quenching and case-hardening steels. An advanced cutting geometry has achieved significantly improved cutting behavior, positively affecting cutting performance and tool life. Optimized cutting geometry for increased machining performance and reduced cutting forces. The chip angles are designed for universal use with various steel types. Improved chip removal through U-shaped chip grooves. The special geometry of the chip grooves reduces the thermal load on the HSS core drill, as the heat generated during machining is largely dissipated with the chips. Reduced friction between the HSS core drill and the workpiece through optimized, spiral-shaped guiding phases. Usable in all pillar and magnetic stand drilling machines with Morse taper in conjunction with RUKO holders or with Weldon shank direct mounting.
