Following the introduction of three high-performance ISO-P cemented carbide grades, TP1000, TP2000, and TP3000 two years ago, Sweden's Seco (SECO) has newly launched the TP2500 general-purpose ISO-P cemented carbide grade known as the "new industry standard".
A new grade of hard alloy coating, which is a new grade of hard alloy coating formed by the coating technology called DurAtomic on Seco's new generation Triple-Zero base material. The a-Al2O3 of the DurAtomic coating is grown from atoms, and the DurAtomic coating has higher wear resistance and toughness than the a-Al2O3 produced by the usual CVD coating.
TP2500 is designed as the first choice grade for ordinary steel turning (ISOP15~P30), and can also be used as a supplementary grade for ISOM20 and ISOK30. According to Seco's technical staff, the new TP2500 inserts can improve machining efficiency by more than 50% and tool life by more than 300%.
