VBMT160412-MM4 WMP20G — Turning insert for stainless‑steel turning (Tiger‑tec Gold) by Walter Tools

A VBMT160412-MM4 WMP20G turning insert optimised for robust machining of stainless steels, featuring a Rhombus 35° geometry and an MM4 chipbreaker for controlled chip formation

• Tiger‑tec Gold coated carbide grade WMP20G
• Optimised chip control with MM4 chipbreaker
• Rhombus 35° geometry with 1.2 mm corner radius
• Suited for machining stainless steel (ISO group M)

Longer tool life and process stability for stainless‑steel turning

The coated carbide grade WMP20G, part of the Tiger‑tec Gold series, is formulated to resist the thermal and mechanical stresses typical of stainless‑steel turning. The combination of a hard, wear‑resistant coating and a stable substrate reduces the tendency for built‑up edge and extends the interval between indexings. For production environments requiring consistent surface finish and repeatable performance, this insert provides measurable improvements in edge stability and tool life compared with uncoated grades.

Predictable chip control and machine uptime

The MM4 chipbreaker is engineered to produce short, manageable chips in medium to robust cutting conditions, improving swarf evacuation and reducing the risk of entanglement. The Rhombus 35° form and 1.2 mm corner radius contribute to a balanced cutting edge that lowers vibration and supports steady metal removal. These features together help to reduce downtime associated with chip handling and rework, supporting smoother cycles and more predictable machining output.

Practical integration into production workflows

Designed for demanding stainless‑steel applications, the insert suits operations where process reliability and repeatable results are priorities. The VBMT160412‑MM4 WMP20G grade performs well under increased thermal load and is recommended for medium to heavy duty turning of ISO group M materials. Specification‑driven selection of insert geometry and radius helps to harmonise cutting forces and surface integrity, so components meet tolerance and finish requirements with fewer tool changes.

FAQ

Which materials is this insert intended for?
The VBMT160412‑MM4 WMP20G insert from Walter Tools is designed primarily for stainless‑steel turning (ISO group M) and performs well in medium to robust machining conditions.

What are the key geometry values for the insert?
This turning insert features a Rhombus 35° form, a 1.2 mm corner radius and a 5° relief angle, providing a balance between edge strength and cutting access.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker promotes short, controlled chip formation for improved evacuation and reduced handling issues, helping to maintain machine uptime and consistent surface quality when turning stainless steel.

Is the grade coated and what advantage does that bring?
Yes — the WMP20G grade is a Tiger‑tec Gold coated carbide. The coating improves thermal and abrasive resistance, supporting longer edge life and better performance under the higher temperatures associated with stainless‑steel machining.
