Ruko drill 40 mm 1 pc.

Cutting depth: 30 mm - core drill made of cobalt-alloyed high-performance high-speed steel with higher heat hardness resistance. 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 geometry has achieved significantly improved cutting behavior, positively impacting cutting performance and tool life. Optimized cutting geometry for increased material removal rate and reduced cutting forces. The chip angles are designed for universal use with various steel grades. Improved chip removal through U-shaped chip ejection. The special geometry of the chip ejection reduces the thermal load on the HSS core drill, as the heat generated during machining is largely dissipated with the chip. 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.
