VBMT110308-MM4 WMP20G indexable turning insert — Tiger‑tec Gold, for stainless steel | Walter Tools

The VBMT110308-MM4 WMP20G is an indexable turning insert engineered for reliable finishing and semi‑roughing of stainless steel under moderate to robust conditions.

• Tiger‑tec Gold coating for high process reliability
• Optimised MM4 chipbreaker for stable chip control
• Rhombic 35° shape, 0.8 mm corner radius
• Designed for stainless steel machining, 5° relief

Consistent chip control and extended edge life

The coated carbide grade WMP20G from the Tiger‑tec Gold family combines a wear‑resistant surface treatment with a geometry that supports stable chip formation when machining stainless steel. The MM4 chipbreaker is tailored to fragment and evacuate chips efficiently, reducing the risk of built‑up edge that typically plagues austenitic grades. As a result, tool life is extended and interruptions for edge dressing or premature index changes are minimised, which benefits batch production and repetitive turning tasks.

Predictable machining and improved throughput

With a rhombic 35° footprint and a 0.8 mm corner radius, the insert provides a balance between strength and surface quality: the geometry permits light to moderate engagement while maintaining a robust cutting edge for interrupted cuts. The 5° relief angle supports low cutting forces and good surface finish on delicate stainless components. The VBMT form is compatible with standard toolholder systems, enabling quick integration into existing turning stations and predictable cycle times across similar part families.

Simple handling and process security

The insert’s nominal dimensions (size 11, thickness 03) and the standard VBMT mounting result in straightforward indexing and repeatable seating in the toolholder. The coated grade helps to maintain a stable cutting edge across variable feed and speed ranges, which simplifies process parameter selection for production engineers. For non‑specialists: a chipbreaker controls how the swarf breaks and flows away from the cutting zone; by using an optimised breaker like MM4, the machining process becomes safer, cleaner and easier to automate.
