SCMT120412-RM4 WSM30S – Indexable turning insert (Square 90°, Tiger·tec Silver) by Walter Tools

A SCMT120412-RM4 WSM30S indexable insert engineered for precision turning and boring of stainless steels and heat‑resistant alloys, optimised for secure chip formation and long machining cycles

• Tiger·tec Silver coated grade WSM30S
• RM4 chipbreaker for controlled chip flow
• 7° clearance for stable cutting geometry
• 1.2 mm corner radius, square 90° insert

Reliable chip control for difficult-to-machine materials

The combination of a dedicated WSM30S grade and the RM4 chipbreaker provides consistent chip control, which reduces the risk of built-up edge and improves process stability when tackling stainless steel and high‑temperature alloys. The insert geometry directs chips away from the cutting zone, lowering the chance of re-cutting and protecting the cutting edge. For production environments this translates into fewer interruptions, steadier cycle times and a more predictable surface finish. The term “chipbreaker” denotes the groove and micro‑geometry that break and control the chips; here it is tuned for sticky, work‑hardening materials where controlled evacuation is essential.

Extended tool life and constant cutting performance

The Tiger·tec Silver coating technology supports higher temperatures at the cutting edge and enhances wear resistance, delivering longer service life in continuous operations. Combined with the robust corner radius of 1.2 mm and a 7° clearance angle, the insert resists edge chipping and maintains dimensional stability over extended runs. This is especially advantageous for shops seeking to reduce tool changes and increase machine uptime. The result is a measurable improvement in productivity and lower effective tool cost per component, as the insert sustains cutting forces and surface quality under demanding conditions.

Precision fit and straightforward machine integration

The SCMT120412-RM4 format – a square 90° insert with a nominal 12 mm size and a compact thickness – fits standard toolholders for turning and cutting‑off operations, enabling quick integration into existing setups without extensive fixture changes. The tolerance class M ensures consistent geometry batch to batch, supporting repeatable part quality. Where process documentation is required, this insert’s specification aids in setting reliable cutting parameters for stainless steels and superalloys, and the clear designation simplifies procurement and tool management in a production setting.

FAQ

What materials is this insert suitable for?
The SCMT120412‑RM4 WSM30S insert from Walter Tools is designed for stainless steels (ISO group M) and for heat‑resistant superalloys and titanium (ISO group S), offering thermal and edge stability for those materials.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker on this insert controls chip shape and evacuation, reducing re‑cutting and helping to prevent built‑up edge when machining sticky or work‑hardening materials.

What does the Tiger·tec Silver grade offer in practice?
Tiger·tec Silver coating enhances heat resistance and wear performance, which in practice means longer tool life and more consistent surface finishes during continuous or high‑temperature cutting.

Can the insert be used in standard toolholders?
Yes, the SCMT120412‑RM4 conforms to common square 90° insert formats and fits standard turning and boring holders that accept SCMT‑type inserts.
