For turning stainless steel components – regardless of whether they be cast, forged or semi-finished parts – Ceratizit says it now has the optimum insert in its range.

The established CTPM125 carbide grade has been joined by two new cutting materials to complete the product range: the more wear-resistant CTCM120 and the tougher CTCM130. Both feature the latest Dragonskin coating.

The arrival of these two new carbide grades, which are recommended for turning austenitic stainless steels, 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 of providing a wider selection of inserts to cover every application from roughing to fine machining.

CTCM120 is said to allow high cutting speeds on austenitic stainless steels and boasts a smooth cut. According to Ceratizit, the grade also impresses with its long tool life, which in some cases was double that of the competition in benchmark tests.

The tough CTCM130 carbide grade is recommended for interrupted cuts. If cutting speeds need to be kept low and conditions are unstable, the attributes of CTCM130 help to increase process security.

Ceratizit’s complete range for austenitic stainless steels is characterised not just by the precise co-ordination of the three grades, but by the free selection of different chip breakers. Depending on the application, customers can choose from three geometries for negative indexable inserts, or two for positive inserts.
