DNMG150604-MM5 WMP20G turning insert — Tiger·tec Gold (Walter Tools)

The DNMG150604-MM5 WMP20G is a rhombic 55° turning insert optimised for machining stainless steel under medium to robust cutting conditions, offering a coated carbide grade designed for secure chip control and repeatable performance.

• Tiger·tec Gold coating for improved wear resistance
• Optimised for stainless steel (ISO M) machining
• Rhombic 55° profile with 0.4 mm nose radius
• Negative 0° lead angle for stable cutting

Reliable performance for stainless steel turning

The WMP20G grade is a coated carbide developed within the Tiger·tec Gold technology and is specifically intended for machining stainless steel (ISO group M). This grade supports a controlled interaction between the cutting edge and tough, work-hardened materials that commonly occur with austenitic and duplex stainless steels. As a result, the tool helps to reduce the risk of built-up edge and minimise thermal damage to the workpiece. The combination of grade and chipbreaker improves process reliability and supports consistent cycle times in serial production.

Wear resistance and process security that improves productivity

A coated substrate provides enhanced wear resistance compared with uncoated grades; in this case, the insert’s coated carbide construction and the MM5 chipbreaker promote stable chip formation and predictable flank wear. Stable edge behaviour reduces interruptions from rework or tool changes and contributes to higher machine utilisation. For machining environments with fluctuating cutting conditions, the insert’s specification is oriented towards maintaining cutting performance over longer tool life, delivering tangible benefits in daily production processes.

Geometry built for precision and controlled cutting

The insert’s rhombic 55° outline and 0.4 mm nose radius create a balance between accuracy and strength: the geometry enables fine surface finishes while retaining sufficient edge toughness for intermittent cuts. The negative 0° lead supports robust engagement and reduces the tendency for chatter in heavier cuts. The plate size (15) and thickness code (06) suit standard turn-holding systems and allow straightforward indexing when the cutting edge requires renewal, helping to maintain consistent component tolerances across repeat runs.

Practical integration and handling in the workshop

Designed as an indexable turning insert, this variant offers straightforward integration into conventional toolholders that accept the DNMG style. The DNMG150604-MM5 form factor and the MM5 chip control geometry support secure chip evacuation in many stainless steel turning tasks, from semi-finishing to more demanding turning operations. The combination of geometry, grade and series characteristics ensures compatibility with established machining processes and simplifies tool inventory for operations focused on rostfreier Stahl.

FAQ

What materials is this insert suitable for?
This insert is specified for stainless steel (ISO M); the WMP20G grade and Tiger·tec Gold coating are tailored to handle the toughness and heat generation typical of these materials.

How does the Tiger·tec Gold coating benefit the machining process?
The Tiger·tec Gold coating on the WMP20G grade increases wear resistance and contributes to consistent edge life, which supports longer intervals between indexing and steadier process output with Walter Tools inserts.

What role does the MM5 chipbreaker play in cutting performance?
The MM5 chipbreaker is engineered for controlled chip formation during turning; when combined with the DNMG150604-MM5 geometry it improves chip control and reduces the risk of entanglement in stainless steel operations.

Is this insert intended for finishing or roughing cuts?
The geometry and grade suit medium to robust cutting conditions; the 0.4 mm nose radius and rhombic 55° profile allow for precise finishes while the negative lead and coated substrate support tougher, more demanding cuts.

Which features ensure repeatable dimensional accuracy?
The rhombic 55° form and consistent coating/substrate combination provide repeatable edge behaviour and reliable indexing, helping to maintain component tolerances across production batches.
