Beskrivelse
Cutting depth: 35 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.
