TNMG220408-RM5 WSM30S – indexable turning insert with Tiger·tec Silver coating by Walter Tools (triangle 60°, negative 0°)

A high-performance triangle insert designed for reliable turning in stainless steels and heat-resistant superalloys, combining a robust edge geometry with the Tiger·tec Silver coated carbide grade.

• Triangle 60° geometry for versatile turning
• Tiger·tec Silver coated carbide grade WSM30S
• RM5 chipbreaker for stable chip control
• 0.8 mm corner radius for robust edge integrity

Achieve reliable cutting in tough materials with a heat-resistant grade

The Tiger·tec Silver grade WSM30S is a coated carbide development aimed at machining demanding materials. Designed for ISO groups M (stainless steels) and S (superalloys and titanium), the grade emphasises heat resistance and stable chip formation. In practice this means fewer unscheduled tool changes and a more predictable tool life under elevated cutting temperatures. The specific coating structure reduces adhesion and improves wear resistance, enabling consistent performance during both roughing and light finishing operations.

Geometry and chip control deliver consistent surface quality

The triangular 60° form and the RM5 chipbreaker create a balance between cutting force distribution and chip evacuation. The insert’s 0.8 mm corner radius increases edge strength, reducing the risk of chipping in interrupted cuts, while the negative 0° rake supports a controlled cutting action on tougher workpiece materials. Together these elements help achieve a reproducible surface finish and dimensional stability, especially when machining long-running batches where repeatability matters.

Practical benefits for workshop productivity and process security

As an indexable insert, this type simplifies tool management and reduces regrinding complexity: one insert size fits standard TNMG toolholders and allows rapid index changes. The coating and substrate combination focused on tool life and heat tolerance decreases downtime and contributes to better cost-in-use figures over a production run. Where operators face build-up edge or thermal softening, the grade’s wear characteristics support continuous operation and reduce the incidence of rework. For purchasers seeking predictable machining of rostfreiem material and superalloys, the insert is a practical choice that supports productive, repeatable turning.

FAQ

What materials is this insert best suited for?
The TNMG220408-RM5 WSM30S is optimised for stainless steels (ISO group M) and heat-resistant superalloys or titanium (ISO group S), offering wear resistance and stable chip control for these demanding materials.

Which chipbreaking behaviour can be expected with RM5?
The RM5 chipbreaker promotes compact and controllable chips in turning operations, improving evacuation and reducing the risk of entanglement, particularly when machining sticky or ductile materials.

Is this insert compatible with standard TNMG toolholders?
Yes, the designation corresponds to established TNMG dimensions and is compatible with toolholders designed for TNMG inserts of the same size and clamping style.

How does the Tiger·tec Silver coating benefit production runs?
The Tiger·tec Silver coating increases heat and wear resistance, which translates into longer tool life, fewer insert changes and improved process stability over extended cycles.

What cutting edge does the 0.8 mm corner radius provide?
A 0.8 mm corner radius delivers enhanced edge strength for interrupted cuts and contributes to consistent surface quality while maintaining reasonable cutting forces for stable turning.
