The optimum tool solution
Modern cutting tools correctly applied and with optimized cutting data have a major cost saving effect! Our grades and geometries are dedicated for peak performance in a specific material with optimized cutting data for first-rate performance.

In order to guide you to the best choice for your operation we have added three groups of workpiece material - N for aluminium, S for heat resistant super alloys and H for hardened steels - to the existing P, M and K groups.

GC4205
A CVD coated grade with excellent resistance against craterwear and plastic deformation. Recommended for stable conditions when higher metal removal rate is needed in medium to rough steel applications. Is able to withstand high temperatures without sacrificing edge line security in wet and dry machining.

GC4215
MTCVD TiCN coated grade with a thicker Al203 low stress aluminium layer provides maximum thermal and chemical protection. Wide application range in different steels, from low carbon through to low and high alloyed. Also a good back up for toughness demanding cast iron turning applications.

A gradient substrate with optimized hardness and toughness for steel turning in combination with a thick wear resistant coating. This grade can handle continous cuts as well as interrupted, a grade for a broad application area.

GC4235
The low stress MTCVD TiCN coating ensures a wide application in demanding operations. Though optimized for unstable conditions in steel turning, GC4235 also works well in stainless steels. The versatility, together with its secure and reliable performance make this grade ideal for unmanned and automated production.

GC3005
CVD-coated carbide consisting of a wear resistant coating with very good adhesion to a hard substrate and capable of withstanding high cutting speed. For finishing of nodular iron, high strength malleable iron and alloyed grey iron with high surface demands and for finishing and semi-finishing at high cutting speed of high alloy steels with high surface demands.


GC2015
CVD-coated carbide grade for finishing and light roughing of stainless steels. A substrate, which can handle high temperatures, combined with a wear resistant coating makes this grade a first choice for continuous cuts at moderate to high cutting speeds.

GC2025
CVD-coated carbide optimized for semi-finishing to roughing of austenitic stainless and duplex stainless steels at moderate cutting speeds. Good resistance to thermal and mechanical shock provides excellent edge security also for interrupted cuts.

GC2035
PVD-coated carbide. Recommended for semi-finishing of austenitic stainless and duplex stainless steels at low to moderate cutting speeds. Great resistance to thermal shock makes it ideal for applications with fast intermittent cuts.

GC235
CVD-coated carbide grade for roughing of steel and steel castings in the most unfavorable conditions. The tough substrate provides extremely good edge security which allows the grade to handle heavy interrupted cuts at low speeds.


GC1125
A PVD-coated micro-grain carbide. Recommended for finishing of all kinds of stainless steels, using medium to low cutting speeds. Excellent when sharp cutting action combined with superior edge toughness or surface finish is needed. Great resistance to thermal shock makes it also suitable for light intermittent cuts.


CB7050/CB50
Extremely hard Cubic Boron Nitride grades. High edge toughness and good wear resistance make them optimal for high speed finishing of grey cast iron under continuous as well as interruupted conditions.

CC6090
Pure silicon nitride based ceramic providing good wear resistance at high temperatures. Recommended for high speed roughing to finishing of cast irons under good conditions. Is able to handle some interruptions.

GC1690
A CVD-coated silicon nitrice ceramic grade. The properties of GC1690 make it highly suitable for light roughing, medium and finishing applications in cast iron.
