Seco Tools Inc. has expanded its Duratomic process technology into a separate and optimized grade chain for grooving and parting-off applications through the introduction of TGP25 for steels and TGP45 for a range of materials. The process occurs when the aluminum oxide (Al2O3) is arranged at the atomic level to adjust the coating to fit specific applications and workpieces. Both of the grades also feature tailored substrates. When compared with the company’s previous competitive grades, the TGP grades offer major improvements in durability and versatility, the company says.

While TGP25 is developed mainly for machining steel and TGP45 for parting-off steel, both are also suited for stable and high-speed applications in stainless steel, and as a tough alternative for cast iron. According to the company, features include excellent levels of heat resistance resulting in faster feeds and speeds; prolonged and predictable tool life enabling unmanned production; extreme flank wear resistance for accurately machined parts over a long period of time; low risk of edge build-up, resulting in superior surface finish; and an application window for flexibility and versatility.

TGP25 is being offered in inserts for groove turning to complement the company’s multi-directional turning program. When compared with the company’s existing solution for this market, the grade offers a 10 to 20 percent increase in cutting speed to improve productivity while maintaining tool life, the company says.
