TCMT16T308-RM4 WSM30S — triangular insert for heavy-duty stainless and superalloy machining (Walter Tools)

The TCMT16T308-RM4 WSM30S is a triangular indexable insert designed for turning and boring applications, optimised for rostfreier Stahl and heat-resistant superalloys using the Tiger·tec Silver coating technology

• Tiger·tec Silver coated carbide grade WSM30S
• Suitable for rostfreier Stahl and superalloys
• Triangle 60° form with 0.8 mm corner radius

Consistent performance on rostfreier Stahl and superalloys

The coated cemented carbide grade WSM30S is engineered for materials that challenge conventional inserts. When machining rostfreier Stahl, components tend to work-harden and generate high temperatures; the Tiger·tec Silver coating promotes stable cutting edges and improved thermal resistance, reducing the risk of built-up edge. For high-temperature alloys and titanium (group S), the combination of grade and geometry supports controlled wear progression, helping to maintain dimensional accuracy and surface integrity over longer tool life.

Geometry that improves chip control and process reliability

The triangular 60° shape with a 0.8 mm corner radius and 7° clearance angle provides a robust cutting edge for moderate to heavy depths of cut. The RM4 chipbreaker is matched to the grade and geometry to encourage short, predictable chips during interrupted cuts and unstable setups. This design choice reduces vibration and promotes reliable chip evacuation, which in turn cuts rework and improves cycle-time consistency in production environments.

Coating and grade deliver extended edge life

The insert’s coated hardmetal construction combines a wear-resistant substrate with the Tiger·tec Silver multilayer coating, optimised for adhesion and heat resistance. This technical combination increases process security by delaying flank and crater wear under elevated cutting temperatures. The result is fewer insert changes, improved tool-life economics and a more stable surface finish — advantages that become tangible in serial production and in the machining of challenging alloys.

Practical application and handling benefits

The insert is supplied in the TCMT16T308-RM4 geometry and is suited to turning and boring toolholders that accept triangular 60° inserts. The insert’s tolerance class M ensures reproducible seating and orientation, simplifying indexable insert changes and setup repeatability. For shops seeking productivity gains on rostfreier Stahl and superalloys, this insert provides a balance of process stability and predictable maintenance intervals, supporting leaner workflows and fewer interruptions.

FAQ

Which materials is this insert suitable for?
The TCMT16T308-RM4 WSM30S insert by Walter Tools is designed for rostfreier Stahl (ISO group M) and for heat-resistant superalloys and titanium (ISO group S), providing secure chip formation and thermal stability.

What does the WSM30S grade offer?
WSM30S is a coated cemented carbide grade from the Tiger·tec Silver family, optimised for wear resistance and edge stability when machining demanding alloys, particularly rostfreier Stahl and superalloys.

How does the RM4 chipbreaker affect performance?
The RM4 chipbreaker is configured to produce short, controllable chips under varied cutting conditions, improving chip evacuation and reducing the risk of entanglement during interrupted cuts.

Is the triangular shape advantageous for heavy cuts?
The 60° triangular form with a 0.8 mm corner radius provides a strong cutting edge that tolerates moderate to heavy depths of cut and supports repeatable indexing in production toolholders.

What tolerance class applies to this insert?
The insert is supplied in tolerance class M to ensure reproducible seating and orientation in compatible toolholders.
