TCMT110204-FM4 WSM20S — Indexable turning insert, Tiger·tec Silver (Walter Tools)

The TCMT110204-FM4 WSM20S is a triangular 60° indexable insert engineered for turning operations in stainless steel and heat-resistant superalloys, offering a robust combination of coating and geometry for demanding applications.

• Tiger·tec Silver coating for wear resistance
• FM4 chipbreaker for stable chip control
• 7° relief for reliable edge engagement
• Triangular 60° insert with 0.4 mm radius

Longer tool life through controlled wear and chip stability

The WSM20S grade, applied within the Tiger·tec Silver coating family, focuses on thermal resistance and consistent edge performance when machining tough alloys. The coated carbide substrate supports stable chip formation, reducing edge build-up and extending tool life under cyclic temperatures. For processes where heat generation and adhesion are critical — such as machining stainless steel or nickel‑based alloys — the combination of a purpose-designed coating and an optimised FM4 chipbreaker maintains productivity and reduces unplanned tool changes. This results in fewer interruptions and a more predictable tool-change rhythm on production lines.

Precision geometry that improves component finish and process security

The insert’s geometric settings — a 7° clearance angle and a 0.4 mm corner radius on a 60° triangular platform — are selected to balance cutting strength and surface quality. The modest corner radius supports stable engagement at the cutting edge and helps absorb intermittent loads without compromising dimensional repeatability. The triangular shape allows for multiple indexing positions, which reduces tooling costs per edge and supports uninterrupted machining. In practice, these geometry choices translate into improved surface finishes and consistent tolerances when turning small radii or interrupted cuts.

Application versatility and recommendations for challenging materials

Designed for material groups S and M, the grade is suitable for heat‑resistant superalloys and stainless steel, where thermal stability and wear resistance are essential. The FM4 chipbreaker promotes coherent chip evacuation in continuous and semi‑continuous turning, lowering the risk of chip-related disruptions. For best results, pair the insert with stable clamping, appropriate cutting fluids or high-pressure coolant where permitted, and feeds geared to the chosen corner radius to preserve edge integrity. The result is a process that offers higher first‑pass yields and reproducible performance across batches.

FAQ

Which materials is this insert best suited for?
The TCMT110204-FM4 WSM20S insert from Walter Tools is primarily intended for stainless steel and heat‑resistant superalloys (material groups M and S), where its Tiger·tec Silver coating and FM4 chipbreaker offer thermal stability and reliable chip control.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker on the TCMT110204-FM4 promotes compact and manageable chips, enhancing evacuation and reducing the risk of chip interference in turning operations, which supports a more stable cutting process and consistent surface quality.

What are the benefits of the 7° relief and 0.4 mm radius?
The 7° relief reduces rubbing behind the cutting edge while the 0.4 mm corner radius balances edge strength and finish. Together they lower the tendency to build up material on the edge and help maintain dimensional accuracy under load.

Can the insert be rotated to use other cutting edges?
Yes, the triangular 60° format provides multiple indexing positions, enabling economical use of available cutting edges before replacement and supporting continuous production with fewer tool changes.

Is this insert part of a recognised series for matching toolholders?
Yes, the insert is part of the Tiger·tec Silver family by Walter Tools, allowing easy selection of compatible toolholders and accessories within the same product family for process optimisation.
