CCMT09T304‑RM4 WSM30S — Rhombic 80° indexable insert, RM4 chipbreaker, Walter Tools

The CCMT09T304‑RM4 WSM30S is a rhombic 80° indexable insert designed for bored and turned components, optimised for machining stainless steels and heat‑resistant superalloys under demanding conditions.

• High‑temperature stability for tough alloys
• Optimised RM4 chipbreaker for secure chips
• Tiger·tec Silver coating for wear resistance
• Rhombic 80° form with 7° clearance

Greater process security for stainless and superalloy machining

The combination of the WSM30S grade and the Tiger·tec Silver technology delivers enhanced thermal and wear resistance compared with conventional grades. This insert’s coated carbide composition is engineered to resist the adhesive tendencies and rapid heat generation typical of stainless steels and nickel‑based alloys, reducing the risk of built‑up edge and premature flank wear. The outcome is a more predictable cutting edge life and fewer unplanned tool changes, which supports steady production flow and consistent part quality.

Predictable chip control that reduces interruptions

Machining ductile or heat‑resistant materials often leads to troublesome chip forms; the RM4 chipbreaker geometry is developed to shape and control chips for stable evacuation. Improved chip control minimises manual chip clearing and reduces the incidence of surface damage to the workpiece, thereby shortening cycle interruptions and improving operational efficiency. This geometry is particularly effective where secure chip segmentation and guided evacuation are required during continuous turning or boring operations.

Geometry designed for strength and surface quality

The rhombic 80° insert form paired with a 0.4 mm corner radius and 7° clearance angle balances edge strength with fine surface generation. The selected corner radius supports robust cutting edge stability at interrupted cuts and moderate depths of cut, while the 80° form provides versatile engagement for both facing and cylindrical turning tasks. Plate size 09 and thickness T3 ensure a compact footprint with sufficient support for boring and turning applications in medium to heavy machining cycles.

Integration into production and tool management

As a Walter Tools component from the Tiger·tec Silver series, this insert fits established toolholders that accept CCMT‑style geometries and is straightforward to index during maintenance. The clear material designation and the RM4 chipbreaker simplify process planning for stainless steels and superalloys, allowing procurement and toolroom staff to standardise on a grade that covers a wide range of demanding alloys.

FAQ

Is this insert suitable for stainless steels and when should it be preferred?
The CCMT09T304‑RM4 WSM30S is specifically formulated for stainless steels, offering thermal stability and reliable chip control that make it a preferred choice for ductile, work‑hardening alloys.

What advantages does the Tiger·tec Silver technology provide?
Tiger·tec Silver enhances wear resistance and heat shielding on the cutting edge of the WSM30S grade, which contributes to longer edge life and improved process stability when machining demanding materials.

How does the RM4 chipbreaker affect machining results?
The RM4 chipbreaker produces controlled chip forms that ease evacuation and reduce the risk of entanglement or surface damage, resulting in fewer stoppages and more consistent surface quality.

Can this insert be used for both turning and boring operations?
Yes; the rhombic 80° form and the specified dimensions make the insert versatile for both turning and boring tasks where a CCMT geometry is applicable.

What is the recommended corner radius for interrupted cuts with this insert?
The 0.4 mm corner radius offers a balance between edge strength and finish and is suitable for operations that combine moderate depths of cut with occasional interruptions.
