Ideal for drilling hard-to-machine materials and for high demands. Suitable for machining 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 across various steel grades. Improved chip removal through U-shaped chip ejection. The special geometry of the ejection reduces thermal stress on the HSS core drill, as the heat generated during machining is largely dissipated with the chip. 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.
