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. A further developed 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 across various steel grades. Improved chip removal through U-shaped chip flutes. The special geometry of the flutes reduces the thermal stress 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 column and magnetic base drilling machines with Morse taper in conjunction with RUKO holders.
