Chipbreaker Inserts handle difficult to machine materials.

Press Release Summary:



Featuring sharp positive geometry with inclination cutting edge of 14.5°, SF Chipbreaker is suitable for finishing applications in continuous cut with very low cutting forces. SM Chipbreaker consists of wear-resistant, universal geometry for medium machining, suitable for continuous and interrupted cut. Both are available in variety of grades and are suitable for materials with poor machinability such as stainless steels, mild steels, and high temperature alloys.



Original Press Release:



Chipbreaker Turning Inserts for Difficult to Machine Materials New Geometries and Grades for Turning Applications in DTMM



Dormer Pramet now offers the new Pramet SF and SM geometries for machining of high temperature alloys and stainless steel. The two new geometries are new to the Dormer Pramet indexable offer.



The SF geometry features a sharp positive geometry with inclination cutting edge of 14.5° and is suitable for finishing applications in continuous cut with very low cutting forces.  The SM chip-breaker is a wear-resistant, universal geometry for medium machining (finishing up to roughing) suitable for continuous and interrupted cut.



Both new chip-breakers are suitable for materials with poor machinability such as stainless steels, mild steels and high temperature alloys. The SF and oth geometries are available in a variety of grades and have been designed to promote low cutting forces and prevent work-hardening, reducing the risk of vibration when turning thin-walled components. 



In addition to the new geometries, two new turning grades are now available. The PVD coated Pramet T6310 grade features enhanced cutting edge reliability and strength with intermediate Cobalt content substrate for additional hardness and increased abrasion resistance, delivering users prolonged tool life. The Pramet T6310’s triple coating provides durability for higher cutting speeds when machining stainless steel, heat-treated and hardened materials. It is suitable for use with the new SM and SF geometries, as well as Pramet’s existing NF and RM geometries.



These latest products will be of use in extreme environments where they are subjected to tremendous heat and corrosion, for example in the general machining, oil and gas, automotive, medical industry, marine and power generation sectors.
