TP3501 is Intended for rough or intermittent turning in steels and stainless steels as well as general turning of stainless steels. Ti(C,N) + Al2O3 DURATOMIC® -F1 Chipbreaker - Chipbreaker for positive inserts. Positive geometry with sharp cutting edge gives easy-cutting properties. Suitable for high feed rates at fine depths of cut in precision forgings and castings. Indicative machining range: f = 0,1-0,5 mm/rev, ap = 0,2-3,0 mm. Machining in bar automatics, for instance: f = 0,08-0,25 mm/rev, ap = 1-3 mm.
