Ruko drill 17 mm 1 pc.

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. A further developed cutting edge geometry has achieved a 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 grooves. The special geometry of the chip groove reduces the thermal load 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.
