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 tempered and case-hardening steels. A further developed cutting geometry has achieved significantly improved cutting behavior, positively impacting cutting performance and tool life. Optimized cutting geometry for increased machining performance and reduced cutting forces. The chip angles are designed for universal use across various steel types. Improved chip removal through U-shaped chip ejection. The special geometry of the ejection reduces the thermal load on the HSS core drill, as the heat generated during machining is largely carried away with the chips. Reduction of friction between the HSS core drill and the workpiece through optimized, spiral-shaped guiding phases. Usable in all column and magnetic base drilling machines with Morse taper in conjunction with RUKO holders.
