Increased performance for turning on state-of-the-art stainless materials



With the new indexable inserts BCM25T and BCM40T, Boehlerit has expanded its ISO turning programme, making optimised indexable inserts available for a wide range of applications on stainless steels.

Now that Boehlerit has established its attractive and highly successful milling programme on the market, the carbide and tool specialist from the Austrian "steel city" of Kapfenberg is once more setting new standards, this time when it comes to turning on stainless steels. The new indexable inserts BCM25T and BCM40T fulfil all the requirements posed by state-of-the-art, stainless steel materials that can be challenging to machines and are being used more and more frequently.  

The BCM40T is a particularly tough M40 stainless steel grade, ideal for use at low cutting speeds and in unstable machining conditions. The new BCM25T is a "medium alternative" to the well-established grades LCM20/ (M20) and LC435D (M35). For both new turning grades, special substrates and a new PVD layer with a thickness of 7 µm were developed. Other decisive factors for the outstanding performance of the indexable inserts are the innovative cutting edges and chip shape geometries.

Boehlerit now has four stainless turning grades in its ISO turning programme, covering the application areas M20, M25, M35 and M40. This means that optimised indexable inserts are now available for a whole range of cutting speeds, from lower to higher. All four turning grades come in different chip shape geometries, from fine to rough turning geometries.

The new turning grades BCM25T and BCM40T have held their own in extensive field tests and will be presented at the AMB in Stuttgart.
