CCMT09T304‑MM4 WMP20G turning insert — Rhombic 80°, Tiger‑tec Gold (Walter Tools)

A CCMT09T304‑MM4 WMP20G indexable turning insert engineered for machining stainless steel under medium to robust cutting conditions.

• Tiger‑tec Gold coating for extended tool life
• Optimised chip control with MM4 breaker
• Rhombic 80° shape, 0.4 mm corner radius
• 7° relief angle for secure cutting

Proven coating and grade for longer production runs

The Tiger‑tec Gold coating combined with the WMP20G grade provides a balanced performance for demanding turning tasks on stainless steel. The multilayer coating reduces adhesive wear and supports a stable cutting edge under elevated temperatures, which in turn extends component life and reduces tool-change frequency. This results in measurable cost benefits through longer intervals between regrinds and fewer scrap parts. The coated carbide composition is designed to maintain cutting-edge integrity during medium to robust operations, enhancing process reliability in series production.

Geometry that stabilises chip formation and surface quality

The insert’s MM4 chipbreaker and rhombic 80° geometry are configured to promote predictable chip control and a consistent surface finish. A 0.4 mm corner radius helps to balance strength and finish quality, while the 7° relief angle supports secure cutting engagement in stainless material, minimising built‑up edge. Together, these features reduce vibrations and improve dimensional repeatability. For workshops seeking improved cycle times without sacrificing quality, the engineered geometry offers a pragmatic route to higher throughput and fewer rework steps.

Application scope and workshop integration

This indexable insert is sized as a plate 09 with a T3 thickness, suitable for standard turning toolholders that accept CCMT‑style inserts. It is specifically intended for stainless steel machining under medium to heavy conditions where thermal stability and controlled chip evacuation are critical. The design supports straightforward indexation and predictable wear patterns, simplifying tool management and inventory planning. For precise selection of cutting data and holder compatibility, refer to machine specifications and holder manufacturer guidance to ensure optimal clamping and coolant strategies.
