CCMT09T304‑MM4 WMP20S – Rhombic 80° indexable insert for rostfreier Stahl by Walter Tools, 7° clearance, 0.4 mm corner radius

CCMT09T304‑MM4 WMP20S is a coated carbide turning insert intended for medium to robust machining of rostfreier Stahl, offering a balance of edge stability and surface quality in production environments

• Tiger·tec Silver coating for extended tool life
• Optimised MM4 chipbreaker for secure chip control
• Rhombic 80° form with 0.4 mm corner radius
• 7° clearance angle for medium to robust turning

Consistent cutting performance for rostfreier Stahl

The Tiger·tec Silver WMP20S grade combines a modern coating system with a robust carbide substrate to deliver reliable chip formation and reduced tendency to build up on the cutting edge when machining rostfreier Stahl. The coated surface reduces friction and supports thermal stability at the cutting zone, which in turn helps to maintain a sharper edge for longer. For production planners this translates into more predictable tool life and fewer unscheduled indexings, improving overall process efficiency.

Enhanced process reliability and higher output per insert

The insert geometry—a rhombic 80° form with a 0.4 mm corner radius and a 7° clearance angle—has been selected to balance strength and surface finish. The MM4 chipbreaker promotes controlled chip segmentation for medium to heavier feeds, reducing the risk of entangling swarf and enabling stable, continuous turning cycles. The practical result is improved productivity through longer tool cycles and fewer interruptions for regrinding or replacement.

Clear identification and simple integration into tooling systems

The designation indicates form, size, thickness, corner radius and chipbreaker, so the CCMT09T304‑MM4 marking helps to match inserts quickly to compatible tool holders and fixtures. The T3 thickness and size 09 format suit a wide range of commercial turning holders; the modest corner radius supports both finishing and light roughing passes depending on feed. For best results with rostfreier Stahl, use coolant where appropriate and verify insert seating and clamping torque to preserve repeatable performance and cutting-edge stability.

Proven Walter Tools technology for dependable production

Walter Tools designs its grades and geometries for consistent real‑world performance. The Tiger·tec Silver series focuses on wear resistance and stable edge behaviour in demanding materials such as rostfreier Stahl. Choosing a Walter grade means selecting an insert backed by engineering aimed at process reliability and reproducible results across batches, which supports predictable planning in series production and jobshop environments.

FAQ

What does the designation CCMT09T304‑MM4 indicate?
The marking CCMT09T304‑MM4 denotes form, size, thickness, corner radius and the MM4 chipbreaker so the insert can be matched to appropriate tool holders and applications.

Is the WMP20S grade suitable for high heat applications in rostfreier Stahl?
WMP20S, part of the Tiger·tec Silver series, is engineered for improved thermal stability and wear resistance during machining of rostfreier Stahl under medium to robust conditions.

Which operations benefit most from the MM4 chipbreaker?
The MM4 chipbreaker supports controlled chip formation in medium to heavier feeds, making it advantageous for stable roughing and semi‑finishing passes where chip control and process continuity matter.

How does the 0.4 mm corner radius affect surface finish and strength?
A 0.4 mm radius provides a compromise between edge strength and surface quality: it delivers better finish than larger radii while maintaining sufficient edge robustness for typical turning loads.

Can this insert be used in standard CCMT holders?
Yes; the CCMT09T304‑MM4 format is compatible with standard holders that accept CCMT‑style rhombic 80° inserts, provided correct seating and clamping are observed.
