Beskrivelse
Ø 43 mm. Cutting depth: 50 mm – Core drills with tungsten carbide cutters + Tecona 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. 108 102 / 108 103 / 108 104 / 108 105 or a threaded retainer such as the Fein KBM 542 / KBM 65.
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.
