Ruko Core drill HSS with weldon shank 12mm

Ø 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.

• Core drills cut up to ten times faster than twist drills. Core drills only cut the width of the teeth. The core is ejected. Lower energy requirements and less wear result in a longer working life.
• Twist drills have to machine the entire diameter of the hole. This calls for considerfromle downward pressure and high driving power.
• Insert Weldon shank pilot pin into core drill.
• Push core drill into arbor and tighten hexagon socket screw firmly.
• Check proper seating of core drill in arbor holder.
• With the EasyLock arbor, the core drill gets automatically locked.
• Drill to full dimension straight away.
• No centring or pre-drilling required.
• The blade geometry of the core drill permits rapid upward chip removal.
• The spring-loaded pilot pin facilitates removal of the cut-out.
• Observe table of cutting speeds and employ appropriate cooling agent.
