CNMG120404-MM5 WMP30G — Turning indexable insert, Rhombus 80°, 0° negative rake — Walter Tools

CNMG120404-MM5 WMP30G is an indexable turning insert designed for robust performance when machining rostfreier Stahl under medium to demanding conditions.

• Tiger·tec Gold coated carbide grade WMP30G
• Optimised MM5 chipbreaker for stable chips
• Rhombic 80° geometry for versatile turning
• 0.4 mm corner radius for repeatable edge strength

Improved cutting reliability for rostfreier Stahl machining

The combination of the Tiger·tec Gold coating with the WMP30G grade provides a balanced wear resistance and toughness necessary for machining rostfreier Stahl, materials that tend to be tough and generate heat. The insert’s MM5 chipbreaker supports controlled chip formation, reducing the risk of built-up edge and simplifying chip evacuation in interrupted or continuous cuts. As a result, cycle times can be stabilised and tool life extended, which contributes directly to more predictable production planning and less scrap.

Geometry that delivers consistent surface finish and repeatability

The Rhombus 80° shape with a 0° (negative) rake creates a geometry focused on edge strength and stability. The 0.4 mm corner radius helps to spread cutting forces over a larger edge area, which improves resistance to chipping and enables more consistent surface quality across batches. For operations where repeatability and dimensional stability are essential, this insert’s geometry reduces the need for frequent tool changes and rework, supporting higher first-pass yield in serial turning tasks.

Process security and productivity in series production

Coated carbide construction and the design features of this insert are aimed at providing process security in demanding turning environments. The solidly coated substrate and the Tiger·tec Gold technology aid in maintaining a stable cutting edge under thermal and mechanical stress, making the product suitable for subcontractors and production shops focused on uptime and throughput. Compatibility with standard toolholders and straightforward indexable replacement reduce machine downtime; paired with adapted cutting data, the insert supports efficient, repeatable machining cycles.

FAQ

What materials is this insert suitable for?
The CNMG120404-MM5 WMP30G insert is designed primarily for machining rostfreier Stahl; the WMP30G grade supports stable chip formation and edge life in these materials.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker on this Walter Tools insert promotes controlled chip breakage and evacuation, which improves process stability and reduces the likelihood of built-up edge when turning rostfreier Stahl.

What benefits does the Rhombus 80° geometry provide?
Rhombic 80° geometry offers versatility in turning operations, combining accessibility for various turning paths with robust edge support to resist chipping during moderate interruptions.

Can the insert withstand high thermal loads?
The Tiger·tec Gold coating and coated carbide substrate of the WMP30G grade are engineered to maintain process security under elevated temperatures typical for rostfreier Stahl cutting, supporting consistent tool life.

Is the corner radius suitable for finishing operations?
The 0.4 mm corner radius balances edge strength and surface finish; it is appropriate for many semi-finish and finishing passes where a stable edge and repeatable results are required.
