Seco Tools’ TK1001 and TK2001 insert grades feature Duratomic coating process technology. Both grades offer cast iron turning with faster cutting speeds and increased tool life, effectively reducing the number of grades users need to stock for cast iron applications.

Seco’s exclusive Duratomic process manipulates aluminum and oxygen at the atomic level to create insert coatings with unmatched toughness and abrasion resistance. In addition to featuring Duratomic technology, the latest TK grades incorporate new substrates that further enhance hardness and wear resistance.

TK1001 is a hard, fine-grained tungsten carbide turning grade with low binder phase content. Designed primarily for tackling gray cast iron up to semi-stable conditions and nodular cast iron under stable conditions, TK1001 also works on hardened steels in the 40 – 45 Rc range. The grade can handle light interruptions, but is intended for long, uninterrupted cuts, where it achieves high productivity, long tool life and the stability needed for confident unattended machining. Examples of components made utilizing TK1001 include cylinders, brake drums, hubs, housings, brake discs and fittings.

TK2001 is a fine-grained tungsten carbide turning grade with high toughness. Mainly intended for machining nodular cast iron and heavy interrupted cuts on gray cast iron, it also provides strong performance in interrupted finishing operations because of its tough substrate and extra edge toughness. Furthermore, it offers long, predictable tool life in unstable conditions, requiring high edge security, the company says. Examples of components made using TK2001 include differential housings, camshafts, clutches, wheel hubs, shafts and pulleys.     

The new TK grades are available via 211 new inserts in a variety of geometries and chip grooves, ensuring applicability across a range of operations.
