TNMG220412-RM5 WSM30S — Turning indexable insert, Tiger·tec Silver, 1.2 mm corner radius (Walter Tools)

TNMG220412-RM5 WSM30S is a triangular indexable insert designed for stable cutting in stainless steel and high‑temperature alloys, optimised for industrial turning applications

• Tiger·tec Silver coating for long tool life
• Designed for stainless steel and superalloys
• 60° triangular insert, 1.2 mm corner radius
• RM5 chipbreaker for stable chip control

Proven coating and grade for demanding materials

The combination of the Tiger·tec Silver coating with the WSM30S grade delivers improved heat resistance and controlled wear behaviour in demanding turning tasks. The coating reduces adhesion and thermal loading on the cutting edge, which supports a steady cutting process when machining stainless steel and superalloys. This results in fewer unscheduled tool changes and a reduction in process variation, making the insert particularly suitable where reproducible part quality and long runtimes are required.

Geometry engineered for reliable chip control and edge stability

A 60° triangular shape with a 1.2 mm corner radius and negative rake 0° provides robust edge support and predictable engagement in interrupted and continuous cuts. The RM5 chipbreaker is designed to produce short, controllable chips under moderate to heavy cutting conditions, which improves surface finish and reduces the risk of built‑up edge formation. The geometry also aids rigidity in the toolholder, lowering vibration and improving dimensional stability during finishing passes.

Clear suitability and application guidance

The insert targets ISO groups M and S, meaning it is intended for stainless steel (M) and heat‑resistant superalloys and titanium (S). These material classes demand resistance to heat and adhesion; the WSM30S grade is tailored to provide stable cutting edges and consistent chip formation in such alloys. For operators less familiar with ISO group designations: M = stainless steel; S = heat‑resistant alloys and titanium. Selection of cutting parameters should reflect workpiece hardness and alloy behaviour to exploit the insert’s strengths.

Productivity benefits and workshop efficiency

Using a coated, application‑focused insert reduces downtime and increases throughput: durable edge life and predictable wear translate into less frequent indexing and lower tool inventory turnover. The design emphasises process security and repeatable results, which supports lean production and cost control across batch and serial turning operations. Paired tool and holder selection, together with appropriate coolant strategy, will further enhance the economic advantages offered by this insert.

FAQ

What materials is this insert best suited for?
The TNMG220412-RM5 WSM30S insert from Walter Tools is designed for stainless steel (ISO group M) and heat‑resistant superalloys and titanium (ISO group S), offering reliable edge life and controlled chip formation in these materials.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes short, controllable chips under a range of cutting conditions, improving surface finish and reducing the risk of built‑up edge when using the Walter Tools insert in moderate to heavy turning operations.

Which coating improves performance in high‑temperature cutting?
The Tiger·tec Silver coating on the WSM30S grade increases heat resistance and reduces adhesion on the cutting edge, leading to longer tool life and greater process stability in demanding applications.

What are the geometric advantages of the triangular 60° insert?
A 60° triangle provides three usable cutting edges per insert and, combined with the 1.2 mm corner radius and negative rake 0°, delivers robust edge support and predictable cutting behaviour in both continuous and interrupted cuts.
