TCMT16T308-FM4 WSM30S – Triangle indexable insert for drilling, boring and turning by Walter Tools

TCMT16T308-FM4 WSM30S is a triangle 60° indexable insert designed for machining rostfreier Stahl (stainless steels) and heat‑resistant superalloys in demanding industrial applications.

• Tiger‑tec Silver coating for extended life
• FM4 chipbreaker for secure chip control
• 0.8 mm corner radius for profile versatility
• 7° relief angle for stable cutting

High process reliability for stainless steels and superalloys

The coated carbide grade from the Tiger‑tec Silver family combines thermal stability with wear resistance to support continuous operation in challenging materials. The design addresses the typical issues of machining stainless steel and heat‑resistant alloys — built‑up edge formation and high cutting temperatures — by promoting consistent chip formation and reducing the risk of edge deterioration. This results in fewer interruptions and more predictable production cycles.

Consistent chip control and improved surface finish

The integrated FM4 chipbreaker is tuned to evacuate chips reliably under variable cutting conditions, lowering the likelihood of chip jamming and surface damage. In practical terms, stable chip control reduces rework and tool changes, which contributes to higher throughput and better part quality. For shops requiring reproducible finishes, the combination of geometry and chip control supports a dependable and measurable improvement in output.

Geometry that balances strength and adaptability

A 0.8 mm corner radius and a 7° relief angle give the insert a good compromise between edge strength and cutting sensitivity. The triangular 60° shape allows three usable cutting corners per index, improving cost efficiency on batch runs. The insert thickness designation T3 supports secure clamping in typical toolholders used for drilling, boring and turning operations, enabling flexible deployment across common setups.

Coating and material pairing for lasting performance

The WSM30S grade is a coated carbide specifically developed for materials that are hard to machine. The Tiger‑tec Silver coating enhances resistance to adhesion and thermal wear, while the substrate maintains the mechanical support required for interrupted cuts. This technical pairing extends tool life and keeps cutting forces within predictable limits, helping shops to plan maintenance and tooling consumption more accurately.

Practical application notes and benefits

Suitable for workpieces classified under ISO group M (rostfreier Stahl) and S (superalloys, titanium), the insert performs best with cutting data adjusted to the material and the machining operation. Using the right coolant strategy and optimised feeds will make the most of the Tiger‑tec Silver technology and the FM4 chip geometry, reducing the incidence of build‑up and promoting repeatable results across production batches.

FAQ

What materials is this insert suitable for?
The TCMT16T308‑FM4 WSM30S is designed for rostfreier Stahl (stainless steels) and heat‑resistant superalloys (ISO groups M and S), offering secure chip control and thermal resistance for these materials.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker on this Walter Tools insert promotes reliable chip evacuation and reduces build‑up, which helps to maintain surface quality and extend cutting edge life during continuous operation.

How many cutting edges are available per insert?
The triangular 60° geometry provides three usable cutting corners per indexable insert, enabling efficient corner changes and economical use of the insert.

Is the Tiger‑tec Silver coating beneficial for interrupted cuts?
Yes; the Tiger‑tec Silver coating improves adhesion resistance and thermal stability, which contributes to a more durable edge under interrupted cutting and elevated temperatures.

Which insert size and clamping should be used?
The insert has an inscribed circle of 16 mm and a thickness designation T3; use a matching toolholder designed for TCMT‑type triangular inserts to ensure secure clamping and correct seating.
