TNMG160404-MM5 WSM30S indexable turning insert — triangle 60°, r0.4 — Walter Tools

The TNMG160404-MM5 WSM30S is an indexable turning insert designed for precision machining of stainless steels and heat-resistant superalloys in demanding production environments

• Tiger·tec Silver coating for extended tool life
• Suitable for stainless steels and superalloys
• Triangle 60° form with 0.4 mm corner radius
• MM5 chipbreaker for controlled chip formation

High-performance turning for stainless steels and superalloys

The coated WSM30S grade, part of the Tiger·tec Silver family, is tailored to the specific challenges of machining stainless steels and high-temperature alloys. Its substrate and coating combination increase thermal resistance and support a stable cutting edge, reducing the tendency for built-up edge formation that commonly affects tough, ductile materials. For production runs where repeatable surface quality and tool life are essential, this insert offers a measurable improvement in process stability and component consistency.

Predictable chip control that supports productivity

Equipped with the MM5 chipbreaker and a triangle geometry, the insert produces short, controllable chips across a range of feeds and depths of cut. The chip former is balanced for medium cutting conditions and helps prevent chip entanglement in turning operations. Controlled chip formation reduces machining interruptions, lowers rework risk and contributes directly to higher machine utilisation and shorter cycle times — a rational benefit for process planners focused on throughput.

Geometry and edge design for reliable tool life

The triangle 60° form combined with a 0.4 mm (r0.4) corner radius and negative 0° rake angle delivers a compromise between edge strength and form accuracy. The robust edge geometry increases resistance to mechanical and thermal loading, while the insert’s tolerance class M supports consistent positioning and repeatability in tool holders. This results in dependable performance during repeated indexing and simple set-up routines that save time at the tool change stage.

Application-focused coating and material compatibility

The chemical and mechanical characteristics of the Tiger·tec Silver coating on WSM30S enhance adhesion and heat protection, which is particularly valuable when machining materials that dissipate heat poorly. The specification indicates suitability for the ISO groups M and S, meaning the insert is appropriate for stainless steels and for heat-resistant superalloys/titanium respectively. This versatility makes the insert a sensible choice where mixed material batches or demanding alloys are part of the production mix.

For machining tasks that demand stable cutting edges and consistent chip control, consider the Walter Tools TNMG160404-MM5 WSM30S as a reliable option — contact Metav Werkzeuge for tailored recommendations and fast availability

FAQ

What materials is the insert suitable for?
The TNMG160404-MM5 WSM30S insert is specified for ISO groups M and S, making it suitable for stainless steels and heat-resistant superalloys (including titanium).

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating on the WSM30S grade improves thermal resistance and wear behaviour, which supports longer tool life and more consistent cutting-edge performance in demanding turning operations.

Which chipbreaker is integrated and what is its advantage?
The insert uses the MM5 chipbreaker, which is engineered for controlled, short-chip formation under medium cutting conditions, reducing risk of chip entanglement and downtime.

Is the geometry suitable for finishing and semi-finishing operations?
The triangle 60° form with a 0.4 mm corner radius and a negative 0° relief angle provides robustness for semi-finishing and allows reliable edge stability where repeatable surface quality is required.

How does the tolerance class affect mounting and repeatability?
Tolerance class M ensures consistent seat and positioning accuracy in compatible tool holders, aiding in predictable indexing and repeatable machining results.
