TCGT090204-MM4 WSM20S triangle turning insert, Tiger·tec Silver – Walter Tools

A TCGT090204-MM4 WSM20S triangle indexable insert engineered for turning operations in stainless steel and heat‑resistant alloys, offering robust edge stability and consistent chip formation

• Tiger·tec Silver coating, high wear resistance
• Suitable for stainless steels and superalloys
• Triangle 60° form with 0.4 mm corner radius

Durable cutting performance for demanding materials

The combination of the WSM20S grade and the Tiger·tec Silver coating delivers notably improved resistance to abrasive and thermal wear during continuous turning. Designed for machining tough materials, the insert supports stable chip formation and longer cutting intervals, which reduces tool change frequency and increases process uptime. The coated carbide substrate balances toughness and hardness to resist chipping under interrupted cuts, making it suitable for extended production runs on stainless steel and high‑temperature alloys.

Geometry that ensures repeatable accuracy

The triangular 60° shape with a 0.4 mm corner radius and a 7° free cutting angle provides a reliable compromise between strength and cutting edge sharpness. This geometry supports consistent dimensional control and repeatable part quality while offering a defined cutting edge for finishing and semi‑finishing passes. The MM4 chipbreaker is optimised to shape chips reliably, lowering the risk of built‑up edge and improving surface finish without sacrificing mechanical stability.

Practical application guidance for process reliability

Assigned to ISO groups M and S, the insert is intended primarily for stainless steel and heat‑resistant superalloys, including titanium alloys. For best results, combine appropriate feed and speed settings with adequate cooling strategies; the coated grade tolerates elevated temperatures but benefits from controlled cutting parameters to maximise life. The insert’s design supports both continuous and slightly interrupted cuts, making it versatile for shopfloor turning tasks where both efficiency and component quality are required.

Why choose this Walter Tools grade in production

Specified with tolerance class G and a compact form factor, the insert contributes to predictable tool performance and easier process planning. The coded dimensions facilitate quick tool library input and toolholder selection. As a product from Walter Tools, the insert is backed by manufacturing expertise aimed at consistent tool life and predictable wear behaviour—factors that help reduce scrap rates and improve overall machining economics.

FAQ

What materials is this insert suited for?
The TCGT090204-MM4 WSM20S insert is designed primarily for stainless steel and heat‑resistant superalloys (ISO groups M and S) and performs well in applications with high thermal and mechanical loads.

How does the Tiger·tec Silver coating benefit tool life?
The Tiger·tec Silver coating on the WSM20S grade improves resistance to abrasive and thermal wear, extending tool life and maintaining edge integrity under elevated cutting temperatures.

Which geometry features contribute to surface finish and stability?
The triangle 60° form combined with the 0.4 mm corner radius and 7° free cutting angle creates a stable cutting edge for repeatable dimensional control and improved surface finish during finishing and semi‑finishing operations.

Is the MM4 chipbreaker suitable for continuous production?
Yes, the MM4 chipbreaker is optimised for consistent chip control, reducing the likelihood of built‑up edge and supporting continuous production in stainless steel and superalloy turning.

Can toolholders for standard triangle inserts be used with this grade?
Standard toolholders compatible with the TCGT090204 form and size are suitable; ensure correct seat and clamping to maintain repeatable positioning and tool life.
