CCMT120404-RM4 WMP20G turning insert (Rhombic 80°, RM4) by Walter Tools — for rostfreier Stahl

CCMT120404-RM4 WMP20G is an indexable turning insert designed for medium to robust turning of rostfreier Stahl, offering enhanced edge security and reproducible performance

• Tiger·tec Gold coating for extended edge life
• WMP20G grade optimised for rostfreier Stahl
• Rhombic 80° form with 0.4 mm corner radius
• RM4 chipbreaker for consistent chip control

Longer tool life and consistent edges for stainless machining

The combination of the Tiger·tec Gold coating and the WMP20G carbide grade ensures a reliable cutting edge under the typical challenges of rostfreier Stahl: built-up edge tendency, high thermal loading and material toughness. This indexable insert keeps wear mechanisms in check, lengthening service intervals and reducing regrind frequency. For manufacturing environments where repeatability matters, the coated carbide and stable microgeometry provide a measurable improvement in usable tool life and reproducibility.

Predictable chip formation and surface quality

The RM4 chipbreaker is engineered to control chip shape and evacuation during turning, which directly supports a steady machining process and reduced risk of irregular tool marks. With the Rhombic 80° geometry and a 0.4 mm corner radius, the insert balances strength at the cutting edge with the ability to produce good surface finishes on rostfreier Stahl. The result is fewer secondary operations and more predictable part quality in series production.

Geometry and setup explained for process reliability

A 7° relief angle and the rhombic plate form produce a secure seating and cutting orientation for a wide range of turning tasks. The plate designation CCMT120404 indicates the form and nominal dimensions; the thickness and size combination support stable clamping and heat dissipation. When configuring the toolholder and cutting parameters, the indexed geometry helps to maintain constant cutting forces, which benefits machine stability and cycle-time consistency across batches.

Where this insert adds the most value

This insert is particularly suited to workshops and production lines working with rostfreier Stahl under medium to robust conditions, where edge stability and controlled chip flow reduce process interruptions. Using a coated, purpose-designed grade like WMP20G can shorten total machining time by reducing the need for frequent insert changes and rework. For operations targeting consistent outcome and lower overall tool cost per part, this turning insert offers a practical combination of performance and predictability.

FAQ

What materials is this insert suited for?
The CCMT120404-RM4 WMP20G insert is designed specifically for rostfreier Stahl and performs well under medium to robust cutting conditions.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WMP20G grade improves edge life and wear resistance, leading to longer run times and fewer tool changes in stainless machining.

Which chip control can be expected from the RM4 breaker?
The RM4 chipbreaker provides controlled chip formation and reliable evacuation, reducing the chance of entanglement and helping to maintain surface quality.

Is the insert suitable for finishing cuts?
With a 0.4 mm corner radius and rhombic 80° geometry, the insert can produce fine surface finishes when set up with appropriate feeds and speeds.

Can this insert be used in heavy interrupted cuts?
The combination of the rhombic form, relief geometry and WMP20G grade offers robustness for demanding operations; process parameters should be adapted to the specific application.
