The globally unique and patented hexagonal roughing insert stands out in every material application and the distinctive insert geometry delivers significant benefits in the production of bright steel. Combined with the newly developed clamping system, it is a real all-purpose tool for users during bar peeling.
With the hexagonal roughing insert, users are prepared for every material application. Specially developed chip breakers with a tailored cutting edge design guarantee the best results during bar peeling, be it in short-chipping or long-chipping materials.
Optimum geometry for general steel materials.
HNMH roughing insert, can be used on one side
Specially tailored for soft or tough materials such as stainless steel and Ni-based alloys.
HNMJ roughing insert, can be used on two sides
Get the most out of your machining process: achieve the best results in combination with a suitable cartridge system, which enables faster cutting edge exchange thanks to the new patented clamping method.
The innovative Dragonskin coating with the latest nano coating technology produces an extremely smooth tool surface and ensures perfect chip clearance. You benefit from the longest tool life and maximum process security.
The position of the indexable insert in the cartridge is defined geometrically with precision by the 6-edge outside profile. 6 high performance cutting edges guarantee optimum use of the indexable insert.
Shortened length of cut of the cutting edge compared to the RNMH 5018 roughing insert reduces power consumption by up to a factor of 0.7 at a maximum depth of cut of 12 mm.
The finish cutting edge integrated in the roughing insert improves the surface quality on the bar.
Protective chamfers partially applied to the cutting edge stabilise the cutting edge in exposed areas.
Improved heat dissipation through grinding off of the Al2O3 coating on the seating surfaces.
The double-sided version offers 12 high performance cutting edges.
