TCMT220408‑MM4 WSM20S — Triangle 60° turning and boring indexable insert, Tiger‑tec Silver, Walter Tools

A TCMT220408‑MM4 WSM20S triangle 60° indexable insert designed for turning and boring operations, optimised for stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coating for thermal resistance
• Grade WSM20S for stainless steel and superalloys
• Triangle 60° form with 0.8 mm corner radius
• 7° relief and MM4 chipbreaker for stable chips

Consistent performance on stainless steels and superalloys

The insert delivers predictable behaviour when machining difficult‑to‑cut materials thanks to the combination of the WSM20S grade and the Tiger‑tec Silver coating. The grade is formulated to support secure chip formation and a durable cutting edge in materials that tend to work‑harden or generate heat, such as stainless steels and superalloys. This results in lower scrap rates and more consistent component tolerances, which directly supports uptime and repeatable batch quality.

Geometry that stabilises cutting and extends edge life

A triangle 60° form with a 0.8 mm corner radius and 7° relief ensures mechanical strength at the cutting zone and reliable engagement in interrupted cuts. The MM4 chipbreaker is tuned to produce short, controllable chips under a wide range of cutting conditions, reducing the risk of entanglement and easing chip evacuation. Together, these geometric features reduce the likelihood of edge chipping and extend the effective tool life, leading to fewer insert changes and smoother machining cycles.

Process reliability and productivity benefits

The coated indexable insert supports stable machining under elevated temperatures and higher cutting speeds, thanks to the thermal performance of the Tiger‑tec Silver surface technology. Stable edges and improved heat resistance contribute to longer tool life and predictable wear patterns, which simplifies process planning and minimises unplanned interventions. For production environments, this translates into higher component throughput and a more efficient use of machine time.

Practical application guidance for production use

The insert is supplied in the common TCMT220408 format and fits standard toolholders for triangle inserts; the dimensional coding supports fast identification and replacement in tooling systems. The product is suitable for turning and certain boring operations where a robust cutting edge and reliable chip control are required. For integration into tooling setups, select compatible holders rated for indexable triangle inserts and verify cutting data against the workpiece material and machine capability before commencing production.

FAQ

What materials is this insert best suited for?
The TCMT220408‑MM4 WSM20S insert is designed primarily for stainless steels (ISO group M) and heat‑resistant superalloys or titanium alloys (ISO group S), where thermal resistance and stable chip control are required.

How does the Tiger‑tec Silver coating improve performance?
The Tiger‑tec Silver coating increases thermal resistance and wear protection, allowing higher cutting speeds and more consistent edge life when the insert machines demanding materials.

Which chipbreaker is fitted and what benefit does it provide?
The insert features the MM4 chipbreaker, which produces short, manageable chips across a range of cutting conditions, improving chip evacuation and operator safety.

What are the key dimensional identifiers for ordering and tool setup?
Order or reference the SKU TCMT220408‑MM4‑WSM20S‑WALTER; the insert has a 22 inscribed circle, a 0.8 mm corner radius and a triangle 60° form—these dimensions determine compatible toolholders and clamping.
