Product description

Ø 44 mm. Cutting depth: 110 mm - Core drills made of heavy-duty high speed steel with titanium aluminium nitride coating. ; The TiAIN wear-resistant coating increases the surface hardness of the tool to approx. 3,000 HV / micro-hardness and the heat resistance to 900° C. It is characterised by high tenacity plus high thermal and chemical stability and helps to achieve better tool life and cutting values. Suitable for dry finishing due to TiAIN coating. Especially suitable for working with unalloyed and alloyed steel (up to a strength of 1200 N/mm²), high-alloyed chromium steel such as stainless and acidresistant steel, as well as cast iron and tough brass.; 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.

They have a drilling time that is up to 10 times shorter than twist drills. Core drills only machine the tooth width, the drill core is ejected. Lower energy requirements and less wear result in a long service life.
With twist drills, the entire drill diameter must be machined. This requires a lot of force and a high drive power.
Insert the ejector pin into the core drill.
Push the core drill into the holder and tighten the hexagon socket screws firmly.
Make sure the core drill is properly seated in the holder.
With the EasyLock quick-release holder, the core drill is automatically locked.
Drill to size immediately, no more punching or pre-drilling.
The cutting geometry of the core drill enables rapid chip removal upwards.
The spring-loaded ejector pin helps to release the cut-out pieces.
Observe the speed table and use coolant.
