DNMG150412-MM5 WMP20G indexable turning insert by Walter Tools — Tiger·tec Gold grade for rostfreier Stahl machining

A DNMG150412-MM5 WMP20G indexable turning insert engineered for reliable chip control and extended tool life in the machining of rostfreier Stahl under medium to robust cutting conditions

• Tiger·tec Gold coating for extended tool life
• Designed for rostfreier Stahl machining
• MM5 chipbreaker for stable chip control
• Rhombic 55° geometry, 0° negative rake

Greater process security when turning rostfreier Stahl

The combination of the Tiger·tec Gold coating and the WMP20G cutting grade is formulated to manage the specific challenges of rostfreier Stahl: high toughness, tendency to work harden and elevated cutting temperatures. The coated carbide helps maintain a stable cutting edge over longer tool life, reducing the frequency of index changes and contributing to predictable cycle times. This grade supports a balance between wear resistance and toughness, which is particularly advantageous when moving from roughing to semi-finishing passes without sacrificing component integrity.

Stable chip control and improved surface quality

Built around the MM5 chipbreaker and a rhombic 55° geometry, the insert promotes consistent chip formation and evacuation during turning operations. The defined corner radius 1.2 helps to distribute cutting forces and supports a cleaner part finish while maintaining dimensional stability. The 0° (negative) rake angle contributes to a robust edge capable of withstanding interrupted cuts and higher feed rates, making the insert suitable for medium to robust machining tasks where both surface quality and process reliability are required.

Practical benefits for production use

The insert’s compact format (15 mm size and thickness 4 mm) and standard clamping compatibility allow straightforward integration into common toolholders. The coated grade is optimised for real-world workshop conditions: reduced edge build-up, good heat resistance and reproducible performance across batches. For production planning, the predictable wear behaviour of the Tiger·tec Gold series supports effective tool-life scheduling, lower downtime for tool changes and improved overall productivity on rostfreier Stahl components.

FAQ

What materials is this insert suited for?
The DNMG150412-MM5 WMP20G is specified for rostfreier Stahl (ISO group M), where the Tiger·tec Gold grade helps control heat and edge wear during turning.

How does the Tiger·tec Gold coating benefit performance?
Tiger·tec Gold increases thermal and wear resistance of the cutting edge, enabling longer tool life and more consistent cutting behaviour with the WMP20G grade on stainless workpieces.

What role does the MM5 chipbreaker play in machining?
The MM5 chipbreaker provides controlled chip formation and evacuation, reducing the risk of long stringy chips and improving surface finish during continuous and interrupted turning.

Is the geometry suitable for roughing and finishing?
Yes; the rhombic 55° geometry combined with a 1.2 mm corner radius and 0° negative rake balances robustness for heavier cuts with the capacity to achieve good surface quality on finishing passes.

Which SKU should be ordered for this insert?
Order SKU DNMG150412-MM5-WMP20G-WALTER for the Walter Tools DNMG150412-MM5 WMP20G indexable insert.
