Seco Tools TK1001 and TK2001 insert grades with Duratomic-coating are designed to increase turning performance by enabling faster cutting speeds and increased tool life. They also reduce the number of grades needed in cast iron applications, the company says. The TK1001 insert grade can handle gray cast iron from finishing to semi-stable conditions and nodular cast iron under stable conditions as well as hardened steels ranging from 40 to 45 Rc. The TK2001 machines nodular cast iron and gray cast iron in tough applications, including heavy interrupted cuts. The TK grades are available in 211 new geometries and chip grooves.
