Tool steel machining made easy with Toolox®

Toolox® is based on a low carbon concept, with a low carbide content. Carbides are hard to machine so the low carbide content is the reason why Toolox® is easy to machine. The steel is also alloyed with molybdenum, niobium and other alloying elements which further improve machinability.

Deeper cuts and longer insert lifetime

The homogenous structure of Toolox® is property that also improves machinability and reduces wear on the tool inserts.

Cutting tools in Toolox® 44 allow deeper cuts and longer insert lifetime compared to traditional tool steels. Tool manufacturers can provide their customers with tools that give a higher material removal rate and better surface finish in the machined piece.

Faster and easier to machine than standard steels

Comparing Toolox® 33 with the standard steel 1.2312/P20 at the same milling speed shows three times longer insert life length or 20% faster milling speed for Toolox®.

Another machining trial has shown the benefits of using Toolox® compared to 1.2312/P20 in terms of maximum possible cutting speeds and elimination of a stress-relieving heat treatment. The study showed a reduction in overall component cost and a 16% reduction in time to manufacture. Since Toolox® didn’t need any stress relief operation after machining, the manufacturer saved two days of lead time.

The machinability and prehardened properties cut production time and make your production much more cost-effective compared to standard steels. When your customers say they want it fast, you can deliver without compromising on quality and performance.


Milling Toolox® will generate bluish chips which indicates that the heat generated is transferred into the chips and not into the workpiece.

Vibration dampening properties

Tools made of Toolox® give higher productivity and better surface quality to machined parts because of the steel’s unique vibration dampening properties. A study carried out at KTH, the Royal Institute of Technology in Sweden, shows that cutting tools made from Toolox® are more resistant to vibrations.

Stress-free after machining

Toolox® steel is easy to machine. Even after heavy machining, Toolox® is dimensionally stable and normally requires no stress relieving. This is especially useful when machining long thin sections such as gear racks. Even if machined mainly from one side the material stays extremely flat, requiring no straightening and no secondary machining.


“The gear racks we made were absolutely straight: 0.004 mm sidewise deflection and 0.136 mm longitudinal deflection on 1.8 measuring length!”
