Seco used-edge detection means not wasting performance from any edge. Additionally, the new coatings improve heat resistance, chemical inertness and reduce the tendency of workpiece materials to adhere to the cutting edge.

TK 1st choice in ductile cast iron When general cast iron applicability is required TK 1st choice in grey cast iron When productivity is prioritised in all cast irons. Over the past 10 years, we have continued extensive research into the technology that produces our Duratomic technology based coatings.

We have now incorporated all of that knowledge into six new grades: Choose Country canada mexico usa argentina brazil austria belgium belarus czech-republic denmark finland france germany hungary italy netherland norway poland portugal romania portugal russia slovakia slovenia spain sweden switzerland turkey ukraine united-kingdom south-africa china india indonesia japan malaysia republic-of-korea singapore taiwan thailand vietnam australia new-zealand.


Seco adds new duratomic TK insert grades for cast Iron turning – MFG Tech Update

Solve this problem with our new Duratomic inserts, which make it nearly impossible to miss unused edges. The best turning grades ever made. With the refined Duratomic technology, we created a comprehensive selection of grades optimised for high and reliable performance in specific cutting materials and applications.

By controlling and ordering the atoms and crystals, we were able to improve the mechanical properties and thermal and chemical inertness.

The wonderful world of atoms With the refined Duratomic technology, we created a comprehensive selection of grades optimised for high and reliable performance in specific cutting materials and applications. Combined with increased toughness, this created performance far beyond the capabilities of traditional Al2O3 coatings.

A unique new approach to used edge detection makes it very easy to identify unused edges with the naked eye, with the key feature being the fact that there is no impact on overall performance.


Find out more about duratomic grades? The used edge detection was selected to give the highest possible contrast and excel in real-life working conditions in all new Duratomic Technology Grades. The new grades boost productivity and greatly enhance the machining value.

The bonds we have with our customers Last for decades. By keeping the same characteristics and strengths as their predecessors, these six grades represent a substantial improvement in both toughness and wear resistance.

TP 1st choice for secured productivity in steels TP is intended for most toughness demanding applications TP 1st choice grade in steels When reliability is prioritised TP 1st choice in low-alloy steels When prioritizing applicability TP 1st choice in high-carbon steels When productivity has a high priority.
