Core drill HSS with weldon shank (3/4″)

Cutting depth: 30 mm – Core drill made of heavy-duty high speed steel.
Suitable for steel (such as T-brackets, large sheets), cast iron, non-ferrous and light metals.
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 pillar drilling machines with morse taper retainer. In connection with RUKO arbor holders no. 108 302 / 108 303 / 108 315 / 108 316, with RUKO EasyLock no. 108 312 / 108 313 / 108 314 or a weldon direct shank such as the RUKO magnetic-stand RS5e / RS10 drill.
