VNMG160404-MM5 WMP20S — Indexable turning insert, Tiger‑tec Silver, for stainless steel (Walter Tools)

VNMG160404-MM5 WMP20S is a coated indexable turning insert engineered for productive turning of stainless steels, featuring a negative geometry and a dedicated MM5 chipbreaker for stable cutting under medium to robust conditions.

• Tiger‑tec Silver coating
• Optimised MM5 chip control
• Negative 0° geometry for stability
• Rhombus 35° form, 0.4 mm corner radius

Consistent chip formation and process reliability

The combination of the Tiger‑tec Silver coating and the WMP20S grade is designed to promote stable chip control, particularly when machining stainless steel. Coated carbide layers reduce adhesion and heat impact at the cutting edge, which lowers the risk of build‑up and supports longer tool life. The MM5 chipbreaker shapes short, controllable chips that evacuate reliably in turning operations, reducing interruptions and improving spindle utilisation. For production environments seeking predictable cycle times, these properties translate into fewer machine stops and steadier part quality.

Geometry tuned for secure edge life and surface finish

The insert’s rhombus 35° form and negative 0° relief angle deliver a compact cutting geometry that increases robustness in interrupted cuts and heavy engagement. The 0.4 mm corner radius helps to distribute cutting forces and supports a repeatable surface finish without sacrificing edge strength. This geometry is particularly beneficial where tool stability and repeatability matter more than minimal cutting forces, for example in semi‑roughing stages or when facing variable stainless‑steel batches. The compact plate size also enables efficient use of toolholders in tight setups.

Application guidance and selection for machining stainless steels

As a coated carbide grade specified for ISO group M, the insert is suited to the demands of rostfreiem Stahl / stainless steel machining: materials that are tough, prone to work hardening and generate heat at the cutting zone. The indexable turning insert concept allows rapid corner changes and simple inventory management; by selecting the VNMG160404-MM5 WMP20S, operators gain a practical balance between economy and cutting performance. Recommendations for process settings typically favour moderate cutting speeds with stable feed rates to exploit the coating’s heat resistance and the chipbreaker’s evacuation pattern. For precise parameter tuning, Metav Werkzeuge can supply cutting data tailored to specific stainless‑steel grades.

FAQ

What materials is this insert designed for? The VNMG160404-MM5 WMP20S by Walter Tools is specified for ISO group M, making it appropriate for machining stainless steels with tendencies to work‑harden.

How does the MM5 chipbreaker improve machining? The MM5 chipbreaker produces compact, controllable chips; this improves evacuation and reduces the likelihood of chip entanglement during turning with the VNMG160404-MM5 WMP20S.

Is the insert suitable for interrupted cuts? The negative 0° geometry and rhombic 35° form provide increased robustness, so the insert copes well with interrupted cutting conditions and variable engagement.

What benefits does the Tiger‑tec Silver coating bring? Tiger‑tec Silver enhances heat resistance and reduces adhesion at the cutting edge, supporting longer edge life and more consistent performance when machining stainless steel.

Can the insert be used in standard toolholders for VNMG geometry? Yes, the VNMG form and dimensions follow standard VNMG toolholder conventions; compatibility depends on holder clamping and seat specifications.
