Core bit
RUKO GmbH Präzisionswerkzeuge
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.
Core drills HSS Co 5ComPact
Core drills made of cobalt alloyed heavy-duty high speed steel with increased heat resistance. Ideal for drilling materials that are difficult to cut and for the highest demands. Suitable for working with unalloyed and alloyed steel (up to a strength of 1200 N/mm²), hot and cold-working steel and also for reinforced and case-hardened steel.
Core drills HSS-TiAlN
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.
Core drills TC
Core drills with tungsten carbide cutters. Particularly for rail tracks, Hardox / Weldox 400 steel, steel, cast iron, high-alloyed chromium steel such as stainless and acidresistant steel.
