SCMT09T308-FM4 WMP20G – Indexable turning insert, Tiger·tec Gold, for stainless steel (Walter Tools)

The SCMT09T308-FM20G WMP20G indexable turning insert is designed to provide stable cutting performance and consistent chip formation when machining stainless steel under medium to robust conditions.

• Tiger·tec Gold coated carbide for high productivity
• Optimised FM4 chipbreaker for stable chip control
• Designed for stainless steel machining (ISO group M)
• 0.8 mm corner radius, 7° relief for reliable edge strength

High stability and predictable chip formation for stainless steel

The SCMT09T308-FM4 WMP20G insert combines a Tiger·tec Gold coated carbide grade with an FM4 chipbreaker to address the typical challenges of machining stainless steel such as toughness, built-up edge and heat generation. The combination yields stable chip control and reduces the risk of unpredictable edge wear, which translates into more consistent component quality and fewer process interruptions. The coated substrate supports secure chip evacuation even in tougher feeds, maintaining productivity in batch and single-piece production.

Coated carbide technology that extends tool life and process reliability

The Tiger·tec Gold technology used in this grade is a PVD/CVD-style coating solution optimised for coated carbide substrates; it improves thermal stability and wear resistance during interrupted cuts and elevated temperatures. For ISO group M materials, the coating helps prevent adhesion and reduces flank wear, which can lengthen effective tool life and lower tooling costs per part. Explaining the term: coated carbide means a hard metal body with a thin engineered surface layer that enhances abrasion and heat resistance, enabling higher cutting parameters without compromising reliability.

Geometry tailored to edge security and surface finish

The insert’s 0.8 mm corner radius and 7° relief angle combine to deliver a balance between edge strength and surface quality. A square 90° insert form provides rigidity and allows economical use of four cutting corners. The FM4 chipbreaker is designed to produce short, controllable chips in stainless steels, reducing entanglement and supporting safer automated operations. These geometric choices reduce the likelihood of chipping at the cutting edge while offering reproducible dimensional results and a predictable surface finish in prismatic turning tasks.

Practical use, holder compatibility and process integration

This indexable insert is suitable for standard toolholders that accept the SCMT09T3 geometry and is intended for users seeking a practical, production-ready solution for machining rostfreiem stainless steel (ISO group M). In process planning, the grade supports moderate to robust cutting conditions and is a fitting choice where tool life and component consistency are priorities. For technical queries about holder selection, cutting data or process optimisation, Metav Werkzeuge provides application advice to ensure the insert is integrated effectively into existing turning centres and setups.

FAQ

What materials is this insert best suited for?
The SCMT09T308-FM4 WMP20G is primarily designed for stainless steel (ISO group M), where its coating and chipbreaker offer improved chip control and reduced adhesion.

How does the FM4 chipbreaker affect machining performance?
The FM4 chipbreaker optimises chip formation for tougher, ductile materials; in combination with the Tiger·tec Gold grade it promotes short, controllable chips and steadier cutting forces.

Which corner radius and relief does the insert provide?
This insert features a 0.8 mm corner radius and a 7° relief angle, offering a compromise between edge strength and surface finish for demanding turning operations.

Is the insert suitable for automated or unattended machining?
Yes, the combination of the coated grade and FM4 chipbreaker supports predictable chips and stable cutting, making it a suitable choice for automated turning centres and lights-out production.

Can the SCMT09T308-FM4 fit standard toolholders?
The geometry corresponds to common SCMT-style holders; confirm holder compatibility by matching the insert designation and clamping seat before assembly.
