Beskrivelse
Ø 17 mm. Cutting depth: 50 mm – Core drills with tungsten carbide cutters + Tecrona coating.
Particularly for rail tracks, Hardox / Weldox 400 steel, steel, cast iron, high-alloyed chromium steel such as stainless and acidresistant steel.
Considerably improved cutting behaviour was attained by research into the cutting geometry, which has a beneficial effect on cutting performance and drill life.
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 RS 10 / RS20 / RS25e / RS30e / RS40e drill.
Advantages of the Tecrona coating
The Tecrona coating is ideal for all operations that are carried out without cooling or lubrication. It adheres very well to the tool, thereby increasing the surface hardness of the wear protection coating to approximately 4200 HV and the thermal resistance up to 1100°C.
The coefficient of friction is very low for this coating, thereby increasing the service life with low wear.
