{"product_id":"mag-bit-12mm","title":"Ruko Core drill HSS with weldon shank 12mm","description":"\u003cp\u003eØ 12 mm. 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.\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cspan style=\"font-size:16px;\"\u003eCore drills cut up to ten times faster than twist drills. \u003c\/span\u003e\u003cspan style=\"font-size:16px;\"\u003eCore drills only cut the width of the teeth. \u003c\/span\u003e\u003cspan style=\"font-size:16px;\"\u003eThe core is ejected. \u003cspan style=\"font-size:16px;\"\u003eLower energy requirements and less wear result in a longer working life. \u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cspan style=\"font-size:16px;\"\u003eTwist drills have to machine the entire diameter of the hole.
