Always the right solution for machining austenitic, stainless steels. In addition to the established CTPM125, two additional grades now round off our product range: the more wear-resistant CTCM120 and the tougher CTCM130. Thanks to the Dragonskin coating, both grades are high performers and process-secure.
CTCM120
CTPM125
CTCM130
The complete range for austenitic, stainless steels is characterised not just by the precise coordination of the grades, but also by the geometrical interchangeability of the chip breakers.
You can choose from three (negative inserts) or two (positive inserts) chip breakers to suit your application. Available in all three grades!
-F30: For the finishing of stainless steels
-M30: First choice for stainless machining
-M60: Light to medium rough machining
-M25: First choice for fine to medium machining of stainless steels
-M55: First choice for medium machining through to roughing of stainless steels

This diagram illustrates the machining results produced by the new CVD-coated CTCM120 cutting material grade when turning austenitic, stainless steels. The grades were developed specifically for these V2A (e.g. 1.4301) and V4A (1.4545) material groups, which are the most commonly used stainless steels. During this trial, the new grade was compared with the established CTPM125 and the benchmark and was taken through to the end of the tool life. The new development from CERATIZIT excelled with over 50% increase in tool life compared to the competition!
