For turning stainless steel components – regardless of whether they be cast, forged or semi-finished parts – Ceratizit has an optimal insert in its range.

The CTPM125 carbide grade has now been joined by two new cutting materials to complete our product range: these are the more wear-resistant CTCM120 and the tougher CTCM130. Thanks to the application of the latest Dragonskin coating, both grades are high performers and process-secure.

The arrival of these two new carbide grades, which are recommended for turning austenitic, stainless steels and supplement the existing all-round cutting material, coincides with the publication of the new Ceratizit Up2Date supplementary catalogue. Development was focused on the most frequently used stainless steels V2A (e.g. 1.4301) and V4A (1.4545), with the aim to provide the user with a wider selection of inserts to seamlessly cover every application – from roughing to fine machining.

The universal PVD-coated carbide grade CTPM125 has proved its worth over many years. It is characterised by a well-balanced ratio between toughness and elevated-temperature hardness and promises to deliver high reliability when machining all stainless steels.

The new addition to the range is the CVD-coated, highly wear-resistant cutting material grade CTCM120, which allows high cutting speeds with austenitic steels and boasts a smooth cut. It also impresses with its long tool life which in some cases was double that of the competition in benchmark tests.

The particularly tough CTCM130 carbide grade, which Ceratizit recommends for interrupted cuts, for example. If cutting speeds need to be kept low and conditions are unstable, the attributes of CTCM130 helps to increase process security.

The complete range for austenitic, stainless steels is characterised not just by the precise coordination of the three grades, but also by the free selection of different chip breakers. Depending on their application, customers can choose from three geometries for negative indexable inserts or two for positive inserts – across all three cutting material grades. As a result, CERATIZIT has seamlessly covered all application ranges for machining austenitic, stainless steels.
