CNMG160612‑MM5 WMP30G – Indexable turning insert for stainless steel (Tiger‑tec Gold) by Walter Tools

The CNMG160612‑MM5 WMP30G is an indexable turning insert designed for machining stainless steel under medium to robust cutting conditions, combining a coated carbide grade with a dedicated chipbreaker for secure chip control.

• Tiger‑tec Gold coated carbide grade WMP30G
• Optimised for stainless steel machining M
• Rhombic 80° geometry, 0° negative rake
• 1.2 mm corner radius with MM5 chipbreaker

Proven cutting grade for demanding stainless‑steel work

The combination of Tiger‑tec Gold coating and the WMP30G formulation delivers enhanced thermal and wear resistance when machining stainless steel (ISO group M). The coating supports stable cutting edges under elevated temperatures, reducing the tendency for built‑up edge and enabling longer, more predictable tool life. For operations where consistent chip formation and surface consistency matter, this cutting grade offers a measurable improvement in process stability and component quality.

Geometry and chip control that support robust turning

A rhombic 80° geometry and a 0° (negative) relief provide enhanced edge strength for occasional heavier cuts, while the MM5 chipbreaker is engineered to form short, controllable chips in ductile stainless alloys. The 1.2 mm corner radius increases resistance to edge chipping during interrupted cuts and supports better dimensional repeatability. In practice, these design choices reduce rework and machine idle time by decreasing insert change frequency and minimising scrap.

Practical benefits for toolrooms and production lines

As an indexable insert in standard CNMG format, this grade integrates easily into common toolholders and tool‑change routines, lowering setup complexity. The solid, coated carbide construction ensures consistent performance across batches, helping to standardise cycle times and surface finish. Combined with supplier expertise from Walter Tools and distribution via Metav Werkzeuge, the insert supports predictable throughput and efficient inventory management for production environments.

FAQ

What alloys is this insert optimised for?
The CNMG160612‑MM5 WMP30G is optimised for stainless steel (ISO group M) and is formulated to manage the heat and ductility typical of those alloys.

How does the MM5 chipbreaker affect chip formation?
The MM5 chipbreaker produces short, controlled chips in ductile materials, improving chip evacuation and reducing the risk of surface damage during turning with the Walter Tools insert.

Can this insert be used for finishing passes?
Yes; the combination of the Tiger‑tec Gold coating and the 1.2 mm corner radius provides a balance of edge strength and surface quality suitable for many finishing operations on stainless steel.

What does the 0° (negative) relief mean for machining?
A 0° negative relief increases edge robustness and is beneficial for interrupted cuts or conditions requiring higher stability, making the insert well suited to medium to robust cutting situations.

Is the CNMG format compatible with standard holders?
The CNMG form is a standard indexable insert format and is compatible with most holders designed for rhombic 80° CNMG inserts, enabling straightforward integration into existing tool setups.
