Ø 26 mm, cutting depth: 30 mm - can be used in all column and magnetic stand drills with core drill bits made of cobalt-alloyed high-speed work steel with higher heat resistance. Ideal for drilling hard to machine materials and for the most demanding jobs. Suitable for the processing of unalloyed and alloyed steels (up to 1200 N/mm²), hot and cold work steels, as well as for remuneration and application steels.Through a further developed cutting geometry a significantly improved cutting behavior could be achieved, Which has a positive effect on cutting performance and tool life.+ optimized cutting geometry for increased cutting performance and reduced cutting forces.+ the cutting angles are designed for universal use in different steel grades.+ improved chip removal through U-shaped removal. The special geometry of the cut-out reduces the thermal load on the HSS core drill, as the heat generated during machining is dissipated with the chip as far as possible.+ Reduces friction between
