Ruko Core drill HSS Co 5 ComPact with Quick IN-Adapter. Ø 32 mm 108932E

Ø 32 mm. Cutting depth: 50 mm - Core drills made of cobalt alloyed heavy-duty high speed steel with increased heat resistance. Ideal for drilling materials that are difficult to cut and for the highest demands.; Suitable for working with unalloyed and alloyed steel (up to a strength of 1200 N/mm²), hot and cold-working steel and also for reinforced and case-hardened steel.; Considerably improved cutting behaviour was attained by research into the cutting geometry, which has a beneficial effect on cutting performance and drill life.; + Optimised cutting edge geometry for increased cutting performances and reduced cutting forces. ; + The effective cutting angles are designed for universal use in various sorts of steel.; + Improved removal of chips thanks to U-shaped recesses. The specific geometry of the recess reduces the thermal load on the HSS core drill as the heat created in cutting is removed with the chips to a very great extent.; + Reduction of the friction between the HSS core drill and the workpiece thanks to optimised spiral-shaped guide chamfers.; For use in magnetic-stand and column drilling machines in connection with Quick IN-adapter as the Fein KBM 32 Q.
