KERNBOOR HSS 22X30MM 108222 WELDON-19 RUKO

Product description:

• 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.
