Take advantage of the combination of Tiger·tec Silver coating, a RM4 chipbreaker and a compact rhombic 80° geometry for reliable machining of stainless steels and heat‑resistant alloys; order the insert directly via Metav Werkzeuge or ask our consultants if needed CCMT120408-RM4 WSM20S indexable turning insert — Walter Tools, Tiger·tec Silver, RM4 The CCMT120408-RM4 WSM20S is an indexable turning insert designed for demanding work on stainless steels and heat‑resistant alloys, featuring a Tiger·tec Silver coating and a chipbreaker tailored for secure chip formation Tiger·tec Silver coating Optimised for stainless steels (M) Stable cutting edge for superalloys (S) Rhombic 80° format, 0.8 mm corner radius High‑temperature coating that stabilises cutting performance The advanced Tiger·tec Silver coating offers a balanced combination of wear resistance and thermal stability that supports consistent cutting in tough materials. For components made from stainless steel and heat‑resistant alloys the coating reduces built‑up edge and extends effective cutting life, which translates into fewer insert changes and less downtime. This performance advantage is particularly relevant where heat generation and poor thermal conductivity compromise tool life; the combination of coating and substrate ensures a predictable, repeatable machining result. Geometry and chip control for safer heavy machining The insert’s rhombic 80° form and 0.8 mm corner radius deliver a mix of strength at the cutting edge and accessibility for various turning operations. The RM4 chipbreaker is engineered to produce short, controllable chips under demanding conditions, improving surface finish and reducing the risk of chip entanglement. A small relief angle of 7° supports low cutting forces in finish passes while maintaining edge support for roughing, so stable, repeatable parts can be achieved across batch runs. Application focus and process advantages in production Engineered as a coated carbide grade, WSM20S is aimed at series production and repair tasks where material variability and thermal challenges exist. The insert’s balanced properties favour applications that require constant dimensional accuracy and reduced rework, such as medical components, aerospace airframes and precision food‑processing parts in rostfrei materials. Integrated geometry and coating choices contribute to higher process security and consistent surface quality, making the solution a cost‑effective choice for producers seeking dependable throughput.

CCMT120408-RM4 WSM30S RM4 Wendeplatten - Walter Tools
Combining the WSM30S Tiger·tec Silver grade with the RM4 chipbreaker and a rhombic 80° geometry delivers reliable edge life and controlled chips for machining stainless steel and heat‑resistant superalloys; the 7° clearance and 0.8 mm corner radius support consistent surface quality. Order the CCMT120408-RM4 WSM30S directly via Metav Werkzeuge or ask our consultants if needed. CCMT120408-RM4 WSM30S — Turning / boring indexable insert, Tiger·tec Silver (Walter Tools) A CCMT120408-RM4 WSM30S indexable insert designed for demanding turning and boring of stainless steel and high‑temperature alloys. Tiger·tec Silver coated grade WSM30S RM4 chipbreaker for stable chips Rhombus 80° geometry for versatile turning 7° clearance and 0.8 mm corner radius Maximise productivity on hard‑to‑cut materials The combination of the Tiger·tec Silver coating and the WSM30S grade provides enhanced wear resistance and heat management for demanding operations. Coated hardmetal reduces flank and crater wear, which means longer intervals between tool changes and more predictable cycle times. For shops machining stainless steel or heat‑resistant superalloys, this results in fewer interrupts and a steadier production flow. The technical design is oriented toward reliable, repeatable performance rather than trial‑and‑error settings. Predictable chip control and improved process security The dedicated RM4 chipbreaker is engineered to produce stable, controllable chips even under heavy contact conditions. Combined with the Rhombus 80° geometry and a 7° clearance angle, the insert encourages smooth chip evacuation and reduces the risk of built‑up edge. A 0.8 mm corner radius balances edge strength and surface finish: it sustains cutting forces while supporting fine finishing where required. In practice, this lowers scrap rates and shortens post‑process work. Practical form factor for turning and boring operations Thanks to its CCMT shape and the standard 12 inscribed circle with 04 thickness designation, the insert integrates easily into common toolholders for boring and external turning. The form factor offers a compromise between rigidity and accessibility in tight bores or stepped components. As a coated carbide insert, it permits higher cutting speeds compared with uncoated grades, translating into improved material removal rates without sacrificing control. Consistent results and less downtime Choosing a grade tailored for stainless steel and superalloys reduces variability across batches. The coating and substrate pairing deliver a stable cutting edge and consistent surface quality, which supports downstream process reliability. Where repeatability is critical, the predictable wear behaviour of this insert helps maintain tolerances and reduces the need for frequent requalification of tools. For engineering teams, that consistency means clearer planning and lower risk of late rework or delays.

Why indexable inserts are indispensable in modern machining
Indexable inserts, also known as cutting inserts or indexable cutting inserts, are standardised, replaceable cutting elements that mount on tool holders such as turning bits, milling cutters or drills. Made from wear-resistant materials like carbide, cermet, ceramic or other superhard grades, they carry the actual cutting edge and allow a worn corner to be rotated or flipped instead of replacing or regrinding the entire tool body.
How these inserts work and when to choose them
In everyday workshop and production settings, indexable inserts perform the direct material removal on the workpiece. Standard inserts for tool systems without internal coolant typically feature closed faces or a single central fixing hole, with heat evacuation handled by external machine nozzles. Inserts designed for systems with internal coolant are engineered to support coolant flow: they include calculated chipbreaker geometries that guide an internal coolant jet under the chip or, in specialised designs, contain sintered microchannels to direct coolant right to the cutting edge. Such coolant-compatible inserts are essential for machining heat-resistant alloys, heavy cutting operations and deep internal machining, where thermal load and chip control are critical.
Tangible benefits for production and workshop efficiency
Choosing the right indexable inserts delivers measurable operational advantages:
- Reduced downtime: faster changeover because a worn insert is simply indexed rather than the whole tool being replaced.
- Extended cutting-edge life: targeted coolant application and optimised chipbreaker design lower thermal stress and improve tool life.
- Consistent part quality: predictable cutting-edge geometry from standardised inserts maintains tolerances across batches.
- Versatility: availability in carbide, cermet, ceramic and superhard grades permits selection according to workpiece material and cutting conditions.
- Lower tooling costs over time: fewer full-tool replacements and less regrinding required.

FAQ
What materials are indexable inserts available in?
Indexable inserts are available in wear-resistant grades such as carbide, cermet, ceramic and other superhard materials, selected according to the workpiece material and cutting conditions.
When should I choose inserts with internal coolant support?
Choose inserts designed for internal coolant when machining heat-resistant alloys, performing heavy cuts or working in deep internal features, because the coolant reduces thermal load at the cutting edge and actively improves chip breakage.
How do chipbreaker geometries affect performance?
Chipbreaker geometries on indexable inserts guide the chip flow and, when matched to an internal coolant jet, direct the coolant under the chip to control temperature and facilitate reliable chip formation, which extends edge life and stabilises machining.
Can standard inserts be used with external coolant only?
Yes; standard inserts for tool systems without internal coolant typically have closed faces or a central fixing hole and rely on external machine nozzles for heat evacuation, which is sufficient for many routine, accessible cuts.
