CCMT120404-MM4 WMP20G turning insert by Walter Tools — Tiger‑tec Gold coated carbide, for rostfreier Stahl

The CCMT120404-MM4 WMP20G is a rhombic 80° indexable turning insert engineered for medium to robust machining of rostfreier Stahl, offering a balanced mix of wear resistance and secure chip formation.

• Tiger‑tec Gold coated carbide grade
• Optimised for rostfreier Stahl (ISO M)
• Rhombic 80° form with 7° relief
• 0.4 mm corner radius for refined finish
• MM4 chipbreaker for reliable chip control

Durable coating for longer cutting performance

The premium Tiger‑tec Gold coating on this grade provides elevated resistance to abrasive wear and heat, which directly improves the service life of the insert in demanding operations on rostfreier Stahl. Coated carbide reduces adhesive build‑up on the cutting edge and supports a consistent cutting action; this means fewer interruptions for tool changes and more predictable production output. The specification conforms to ISO material grouping M, indicating suitability for stainless steels that typically require coatings and grades that help to avoid edge adhesion and thermal problems.

Geometry that promotes stable machining and surface quality

The rhombic 80° shape combined with a 7° relief angle directs cutting forces to deliver a controlled engagement with the workpiece, while the 0.4 mm corner radius helps to produce a fine finished surface without sacrificing edge strength. The MM4 chipbreaker is designed for effective chip control in medium to heavy cuts; by breaking chips into manageable forms it reduces the risk of entanglement and improves process stability. In practical terms, this geometry supports higher metal removal rates with predictable dimensional results and an improved component finish.

Application benefits and process reliability from a proven brand

As a Walter Tools product of the Tiger‑tec Gold series and grade WMP20G, this insert is intended for workshops and production environments seeking reproducible results when turning rostfreier Stahl under varying cutting conditions. The coated carbide composition and optimised chipbreaking reduce the frequency of unexpected edge wear and rework, contributing to lower overall machining costs and improved uptime. The insert’s balanced design offers a compromise between cutting-edge robustness and surface finish, making it suitable where repeatability and productivity are priorities.

Practical considerations for integration into machining processes

When integrating this insert into a toolholder and process, its rhombic form and chipbreaker strategy favour a stable cutting environment; using appropriate coolant and parameter adjustments for rostfreier Stahl will further enhance edge life. The grade is intended for medium to robust conditions, so settings that avoid excessive heat concentration and promote secure chip evacuation will yield the best results. For customers unfamiliar with coated carbide grades or chipbreaker types, the technical characteristics of the insert translate into easier process control and reduced scrap rates once correct machining parameters are established.

FAQ

Which materials is this insert suitable for?
This insert is optimised for machining rostfreier Stahl (ISO M); the Tiger‑tec Gold coating and grade WMP20G support secure chip formation and reduced adhesion when turning stainless steels.

What does the MM4 chipbreaker do?
The MM4 chipbreaker on the CCMT120404-MM4 WMP20G controls chip form during medium to heavier cuts, improving evacuation and process stability for turning operations.

How does the 0.4 mm corner radius affect the component finish?
A 0.4 mm corner radius balances edge strength and surface quality, enabling finer finishes than larger radii while still providing resistance to edge chipping under robust conditions.

Is this insert compatible with general turning holders for CCMT geometry?
Yes, the CCMT120404-MM4 designation corresponds to standard CCMT indexable insert geometry and fits holders designed for that format; ensure correct seating and clamping for consistent results.

What production advantages can be expected from the Tiger‑tec Gold series?
Products from the Tiger‑tec Gold series, such as this WMP20G grade, offer improved wear resistance and thermal stability, which typically translates to longer tool life and more predictable machining cycles.
