Turning from Start to Finish


​​​New chipbreakers and grades for steel and cast iron, high temperature alloys and stainless steel


The NF1 and NF2 positive chipbreakers support turning applications in stainless steel while the FF2, FM2 and RM3 chipbreakers support steel and cast iron. The SF2 and SF3 positive inserts are first choice for S-group materials and high performance alloys.

The NF1 is a universal chipbreaker for fine finishing to medium machining, peripherally ground to provide a very good surface finish. The versatile NF2 chipbreaker incorporates a small stabilizing T-Land and covers a wide range of applications from semi-finishing to light roughing. 

The FF2 chipbreaker has a positive rake angle and depth of cut from 0.01 inch for fine finishing applications in low carbon steels. The FM2 chipbreaker is for finishing to medium machining and features a protective land suitable for continuous and interrupted operations. The highly resistant RM3 chip​breaker is for roughing applications in steels & cast irons and suitable for unfavorable machining conditions.

The SF2 and SF3 positive inserts provide a highly secure and dependable option for turning applications for S-group materials and high performance alloys. The SF2 chipbreaker is for fine turning at the lowest possible feeds while the SF3 chipbreaker, with its positive inclined cutting edge, supports finishing operations. Especially effective when used on small and slender components, both inserts offer a sharp cutting edge with minimal radius. This promotes low cutting forces which, in turn, prevents work hardening and ensures a high quality surface finish.

Finishing off this new Pramet offering is the T7325 grade for productive machining of stainless steels. It has been developed to complement the existing T7335 grade which is recommended for use in unstable machining environments. Suitable for interrupted cutting, the latest T7325 grade features a functional gradient substrate and special MT-CVD coating. This combination offers high cutti​ng strength, reduced built-up edge and resistance to the formation of cracks. As a result, the grade provides a high level of operational reliability, performance and tool life.
