VCMT160408-MM4 WMP20S — Indexable turning insert, Tiger·tec Silver grade for stainless steel (Walter Tools)

A VCMT160408-MM4 WMP20S indexable turning insert engineered for machining stainless steel with a rhombic 35° geometry, optimised for secure chip formation and reliable edge stability.

Tiger·tec Silver coated grade WMP20S
Designed for stainless steel machining
Rhombic 35° insert, 7° clearance
Corner radius 0.8 mm for stable edge

Reliable machining performance for stainless steel components

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade is tuned for the demands of ISO group M (stainless steel): increased heat resistance and improved wear behaviour support stable chip formation and reduce the risk of built-up edge. In practical terms, this means more predictable tool life and fewer unscheduled tool changes, improving throughput in serial production. The coated carbide substrate provides a balance between toughness and hardness suitable for medium to robust cutting conditions.

Geometry and chip control that protect the workpiece and tool

The rhombic 35° profile and 7° clearance angle promote a favourable cutting action for turning operations where controlled cutting forces and good surface finish are required. The MM4 chipbreaker is designed to guide and fracture chips effectively when machining ductile, work-hardening stainless steels, while the 0.8 mm corner radius gives a robust cutting edge that tolerates interruption and variable feed conditions. These geometric features reduce vibration and support consistent surface quality without complex parameter changes.

Production advantages and process security

With its standard VCMT designation and proven geometry, the insert fits common toolholders and indexable tool systems, simplifying inventory management. The WMP20S grade is aimed at repeatable, reliable performance under typical workshop and factory conditions, helping to reduce setup time and increase machine uptime. For operations seeking predictable output and straightforward grade selection, the plate’s tolerance class M and familiar form factor make integration into existing turning processes straightforward. Walter Tools’ product design emphasises process security and consistent results for demanding machining tasks.

FAQ

Which materials is this insert designed for?
The VCMT160408-MM4 WMP20S insert is designed primarily for stainless steel (ISO group M), as indicated by the WMP20S grade and Tiger·tec Silver coating.

What is the geometry and why does it matter?
The insert uses a rhombic 35° shape with a 7° clearance angle; this geometry supports controlled cutting forces and a good surface finish, making it suitable for many turning applications on stainless steel.

What chipbreaker does the insert use?
This article features the MM4 chipbreaker, which assists in controlled chip formation when machining tough, ductile materials like stainless steels.

What is the corner radius and how does it affect durability?
The corner radius is 0.8 mm, providing a robust cutting edge that increases resistance to edge breakdown and helps maintain consistent surface quality under varying feed conditions.

Is the insert coated and what are the benefits?
Yes, the insert is part of the Tiger·tec Silver family—this coated carbide construction improves wear resistance and thermal stability during stainless steel machining.
