SNMG120404-MM5 WMP20G — Indexable turning insert by Walter Tools (Tiger·tec Gold, for stainless steels)

The SNMG120404-MM5 WMP20G is a square 90° indexable turning insert designed for machining stainless steels under medium to robust conditions, offering coated carbide performance and reliable chip control.

• Tiger·tec Gold coated grade WMP20G
• Optimised for stainless steels (ISO M)
• Square 90° geometry, 0.4 mm corner radius
• MM5 chipbreaker for stable chip control

Reliable performance on stainless steels

The combination of the Tiger·tec Gold coating and the WMP20G cutting grade provides a coated carbide solution tailored to the challenges of machining stainless steels. These materials tend to be tough and generate heat; the insert’s coating and grade improve wear resistance and help maintain a stable cutting edge under elevated temperatures. The result is improved process security and fewer unscheduled tool changes, which contributes directly to a steadier production flow and predictable component quality.

Process stability and economical production

The insert’s square 90° form and 0.4 mm corner radius deliver a balance between edge strength and versatile cutting geometry for a wide range of turning tasks. The MM5 chipbreaker is designed to support consistent chip formation, reducing the risk of entanglement and improving swarf handling in automated and manual turning operations. With a 0° (negative) rake, the geometry prioritises edge robustness, making the insert better suited to heavier cuts and intermittent cuts where secure edge retention is essential.

Application guidance and system compatibility

Classified for ISO group M, this insert is intended specifically for rostfreier Stahl (stainless steels) and performs well in middle to robust cutting conditions. Its geometry and chip control features make it suitable for general turning tasks where build‑up edge and thermal load can compromise surface finish or tool life. For machine setup, pair the insert with a compatible SNMG pocket and select cutting parameters that account for stainless steel’s tendency to work‑harden; Metav Werkzeuge’s advisors can assist with parameter selection and holder recommendations to maximise tool life and process reliability.

FAQ

Which materials is this insert suitable for?
The SNMG120404-MM5 WMP20G from Walter Tools is intended for stainless steels (ISO group M) and is optimised for medium to robust machining conditions.

What does the MM5 chipbreaker do?
The MM5 chipbreaker on this insert improves chip control and supports consistent chip formation, which helps maintain process stability during turning operations.

How does the 0° (negative) rake angle affect performance?
A 0° (negative) rake) increases edge strength and robustness, making the insert suitable for tougher cuts and situations with interrupted cutting.

Is this insert suitable for finishing work?
The geometry and the 0.4 mm corner radius favour robust performance; for fine finishing, consider the required surface tolerance and choose cutting parameters accordingly—Metav Werkzeuge can recommend optimised settings.

What series and coating does the grade use?
The cutting grade is WMP20G, part of the Tiger·tec Gold series, a coated carbide solution designed to improve wear resistance when machining stainless steels.
