Bohr-/Aufbohrwendeschneidplatte CPGT09T304-MM4 WSM20S — indexable insert, Tiger‑tec Silver, Walter Tools (Rhombic 80°, 11° free angle)

The CPGT09T304-MM4 WSM20S is an indexable insert designed for demanding machining tasks on stainless steels and heat‑resistant superalloys, suitable for both drilling/boring and turning applications

• Tiger‑tec Silver coating technology
• Optimised for stainless steels and superalloys
• Rhombic 80° geometry for versatile cutting
• Stable chip control with MM4 breaker

Robust grade for demanding materials and longer tool life

The WSM20S grade, part of the Tiger‑tec Silver series, is a coated carbide solution engineered for materials that challenge conventional tooling. Its composition and coating promote a stable cutting edge under high thermal load, which reduces the frequency of edge breakage and prolongs useful life. For production environments where consistent cycle times and low tool-change frequency matter, this insert delivers measurable improvements in process reliability and uptime. The technical design supports secure chip formation when machining stainless steels and temperature‑resistant alloys, translating into fewer interruptions and more predictable batch throughput.

Geometry and chip control that stabilise machining processes

The insert’s Rhombic 80° shape, combined with the MM4 chipbreaker and an 11° free angle, provides a balance between strength and accessibility into the cut. The 0.4 mm corner radius and T3 thickness contribute to edge stability and allow for reliable shoulder cuts and intermittent engagement. These geometric choices help to maintain dimensional accuracy and surface finish while minimising vibrations. In practice, the design reduces the tendency for built‑up edge on difficult materials, enabling operators to maintain higher feeds and consistent surface quality for longer tool life.

Practical benefits and recommended application areas

This indexable insert is intended for heavy or semi‑finish turning where thermal resistance and chip control are critical. The grade and coating combination is especially appropriate for machining components made from stainless steels and superalloys (ISO groups M and S), where heat generation and material toughness can otherwise compromise the cutting edge. Employing this insert contributes to improved part consistency and less rework, supporting higher productivity and lower total machining costs per component. The product aligns with Walter Tools’ reputation for process security and stable cutting performance, making it suitable for production lines with tight tolerances and repeatability requirements.

FAQ

What materials is this insert best suited for?
The Walter Tools CPGT09T304-MM4 WSM20S insert is formulated for stainless steels and heat‑resistant superalloys (ISO groups M and S), offering enhanced thermal resistance and secure chip formation.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker on the CPGT09T304-MM4 promotes controlled chip formation and evacuation, which reduces the risk of built‑up edge and stabilises the cutting process for consistent surface quality.

Can the insert be used for both turning and boring operations?
Yes, the designation and geometry indicate suitability for drilling/boring and turning inserts; the Rhombic 80° form supports versatile engagement angles for a range of operations.

What advantages does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating enhances heat resistance and wear performance, increasing edge life and enabling higher productivity when machining difficult materials.

Is the corner radius important for surface finish?
The 0.4 mm corner radius contributes to a stable cutting edge and helps achieve consistent surface quality while resisting chipping under interrupted cuts.
