CCMT120408-MM4 WMP20G — Drilling/boring and turning indexable insert, Tiger·tec Gold, Walter Tools

CCMT120408-MM4 WMP20G is an indexable insert designed for turning and boring operations, optimised for stainless applications and medium to robust cutting conditions

• Tiger·tec Gold coated carbide grade
• Optimised for rostfreie Stähle (ISO M)
• CCMT 80° rhombic shape, 0.8 mm corner radius
• MM4 chipbreaker for secure chip control

Consistent cutting performance where material is demanding

The combination of Tiger·tec Gold coating and the WMP20G grade yields reliable performance when machining rostfreie Stähle. The coating technology improves thermal resistance and reduces adhesion tendencies that commonly cause built-up edge in tough alloys; this stabilises the cutting process and helps maintain a predictable edge life. By selecting a coated carbide grade engineered for these conditions, process stability increases and rework rates fall, which supports continuous production and reduces total cost of operation.

Geometry tuned for surface quality and repeatability

The CCMT rhombic 80° layout with a 0.8 mm corner radius and 7° relief angle gives a balance between strength and finish. A 0.8 mm corner radius supports light finishing cuts while still providing enough edge support for interrupted or semi-finish passes; this reduces the likelihood of edge chipping during handling or entry. The 80° lead angle aids stable contact and consistent chip formation, which translates into improved dimensional repeatability and a finer surface on turned or bored components.

Chip control and predictable tool life for efficient production

Equipped with the MM4 chipbreaker, the insert promotes compact, manageable chips in typical rostfreie Stahl machining scenarios, lowering the risk of entanglement and machine interruption. The chip control feature, combined with the Tiger·tec Gold coating, allows for higher duty cycles and fewer tool changes in standard shop-floor conditions. For operations prioritising uptime and throughput, this insert provides measurable gains: fewer stoppages, more consistent cycle times and a dependable cutting edge across batches.

FAQ

What materials is this insert suitable for?
The CCMT120408-MM4 WMP20G insert by Walter Tools is optimised for rostfreie Stähle (ISO M) and is intended for applications that demand secure chip formation and thermal resistance.

Which series and coating does the insert use?
The insert belongs to the Tiger·tec Gold series; the WMP20G grade is a coated carbide designed to improve thermal and wear behaviour during machining.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker on this CCMT insert encourages compact chip formation, which reduces the risk of chip entanglement and contributes to uninterrupted machining cycles.

What does the 0.8 mm corner radius provide?
A 0.8 mm corner radius offers a compromise between edge strength and surface quality, suitable for semi-finish and finishing passes while maintaining robustness against edge damage.

Can this insert be used for general steel or hardened materials?
The supplied data specifies optimisation for rostfreie Stähle (ISO M). Use on other material groups or hardened steels is not indicated in the provided information.
