Seco introduces new turning insert grades for challenging materials
10/22/2013 10:00:00 AM

Fagersta, October 2013 – Seco’s new TH1000 and TH1500 turning insert grades further extend the company’s offerings of extremely wear-resistant solutions for cutting difficult-to-machine materials. Seco has engineered the grades to bring high performance and increased productivity to a range of challenging applications, such as the machining of superalloy and hardened steel components, which are frequently found in both the aerospace and automotive segments. 

TH1000, a TiSiN-TiAIN nanolaminate PVD-coated grade, excels in machining the hardest steels, superalloys and 'hard-faced' materials. It brings reliable toughness and high wear resistance to applications involving these demanding materials, where variations in hardness and interrupted cuts are frequently found. Additionally, the grade is highly resilient, allowing it to resist edge fracture and combined with the well-adapted chipbreakers, promote effective chip control in these types of applications.

Intended to handle higher material removal, the TH1500, a hard Duratomic®-coated grade, provides excellent wear resistance, allowing optimal productivity in continuous cut operations involving moderately hardened steel components (HRC 40-55). Seco’s exclusive Duratomic® coating technology creates an insert coating with unmatched strength. Further, the TH1500 offers superior wear resistance in finishing of cast irons, making it a useful complement to Seco’s dedicated cast iron grades, TK1001 and TK2001.

The chipbreaker range available for the new TH insert grades maximises chip control to provide high process security and longer tool life in a broad range of operations.
