SCMT09T308-RM4 WSM30S indexable turning/boring insert – Tiger·tec Silver, RM4 chipbreaker (Walter Tools)

The SCMT09T308-RM4 WSM30S is a coated carbide indexable insert designed for turning and boring applications in rostfreier Stahl and heat‑resistant superalloys, offering high cut‑edge stability and reliable chip control.

• Tiger·tec Silver coating for heat resistance
• Optimised RM4 chipbreaker for stable chips
• 90° square geometry with 0.8 mm corner radius
• Suited for rostfreier Stahl and superalloys

Secure machining of rostfreier Stahl and superalloys

The WSM30S grade, part of the Tiger·tec Silver family, is formulated for materials classified as M and S according to ISO 513. The chemical and physical behaviour of these materials leads to high cutting temperatures and a tendency to form built‑up edge; the coated hardmetal composition provides increased heat resistance and a durable cutting edge. This translates into fewer edge failures and a more consistent tool life in demanding production runs, reducing unexpected downtime and variances in part quality.

Geometry engineered for consistent results

A 90° square insert with a 0.8 mm corner radius and 7° relief offers a balanced compromise between edge strength and profile definition. The square form allows four cutting corners per indexable insert, supporting economical use, while the corner radius improves load distribution on the cutting edge for interrupted cuts or tougher feeds. With T3 plate thickness and tolerance class M, the insert provides the rigidity and dimensional reliability required for repeatable turning operations in a production environment.

Optimised chip control for reliable production

The RM4 chipbreaker is designed to control chip formation in sticky and cohesive material groups, aiding consistent chip evacuation and reduced recut. Controlled chip shaping helps to protect the insert’s edge and the machine tool, enabling stable machining parameters and predictable cycle times. For process planners, this means easier parameterisation and lower scrap rates when working with heat‑resistant alloys or rostfreier Stahl that typically present chip management challenges.

Practical advantages on the shop floor

Using a coated, medium‑tolerance insert such as this can simplify tool selection across a range of difficult‑to‑machine alloys. The combination of a modern coating system and a robust substrate reduces the frequency of index changes and supports longer intervals between tool inspections. Where surface finish and dimensional consistency matter, the stable cutting edge and optimised chip control contribute directly to part quality, while the insert’s design promotes efficient use of inventory and predictable maintenance intervals.

FAQ

What materials is this insert intended for?
The SCMT09T308‑RM4 WSM30S insert is designed for rostfreier Stahl (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), benefiting from the Tiger·tec Silver coating for improved heat resistance.

How does the RM4 chipbreaker help on the shop floor?
The RM4 chipbreaker shapes and breaks chips reliably in cohesive materials, improving evacuation and reducing recutting when machining difficult alloys with the Walter Tools insert.

What advantages does the 0.8 mm corner radius provide?
A 0.8 mm corner radius increases edge strength and distributes cutting forces, helping to maintain dimensional stability and reduce edge chipping on demanding cuts.

Is this insert suitable for interrupted cuts or heavy feeds?
Yes; the combination of the coated substrate, T3 thickness and a robust corner radius delivers the mechanical stability required for interrupted cuts and heavier feeds in production.

How many indexable corners are available with this geometry?
The square 90° form provides four cutting corners per insert, supporting cost‑efficient indexing and predictable tool usage.
