Ideal for drilling difficult-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 edge geometry has achieved significantly improved cutting behavior, positively impacting cutting performance and tool life. Optimized cutting edge geometry for increased machining performance and reduced cutting forces. The chip angles are designed for universal use with various types of steel. Improved chip removal through U-shaped notches. The special geometry of the notches 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 due to optimized, spiral-shaped guiding phases. Usable in all pillar and magnetic base drilling machines with Morse taper in conjunction with RUKO holders or with Weldon shank direct clamping.
