TCMT110208-RM4 WMP20S – Triangle 60° indexable insert for rostfreier Stahl, Tiger‑tec Silver by Walter Tools

The TCMT110208‑RM4 WMP20S is a coated cemented‑carbide indexable insert engineered for demanding boring and turning operations in rostfreier Stahl; it combines Tiger‑tec Silver coating technology with a geometry tuned for secure chip formation.

• Tiger‑tec Silver coating, WMP20S grade
• Designed for rostfreier Stahl (M) machining
• Triangle 60° form with 0.8 mm corner radius
• 7° clearance angle and RM4 chipbreaker

Higher productivity through optimised grade and coating

The insert’s WMP20S grade, part of the Tiger‑tec Silver series, is developed to extend tool life under the thermal and adhesive challenges of rostfreier Stahl. With a coated cemented carbide substrate and a modern PVD-style coating stack, the insert reduces flank wear and resists built-up edge formation. This results in fewer interruptions for tool changes and more predictable cycle times, so production runs remain steady and output quality becomes more consistent.

Reliable chip control and surface quality

A precisely shaped RM4 chipbreaker and the Triangle 60° form deliver repeatable chip segmentation and evacuation even under the sticky cutting conditions typical of rostfreier Stahl. The 0.8 mm corner radius balances edge strength and fine surface finish, enabling a smooth machined face with reduced post-process grinding. Better chip control lowers the risk of surface defects and protects workpiece geometry, which is particularly important for precision components and serial production.

Geometry and angles tuned for versatile applications

The insert’s 7° clearance angle and its compact insert size ensure stable cutting engagement in both boring and turning set-ups. The combination of clearance and corner geometry reduces rubbing and heat build-up at the cutting edge, allowing for conservative to moderately aggressive cutting parameters without sacrificing component integrity. As a result, the same insert suits a range of operations from finishing to medium-duty machining in rostfreier Stahl.

Cost-effectiveness through fewer interruptions and consistent results

Choosing a Tiger‑tec Silver‑based insert with the WMP20S grade means fewer unscheduled tool exchanges and less scrap due to inconsistent cutting. The robust edge life reduces total tool consumption over time, while the predictable performance supports process planning and cost calculations. For workshops and production lines seeking to raise throughput without sacrificing surface requirements, this insert offers a pragmatic balance of durability and performance.

FAQ

What materials is this insert intended for?
The TCMT110208‑RM4 WMP20S is optimised for rostfreier Stahl (ISO group M) and designed to maintain edge security and chip control in those materials.

How does the RM4 chipbreaker affect performance?
The RM4 chipbreaker on this Walter Tools insert promotes reliable chip segmentation and evacuation, which reduces built‑up edge and improves surface finish when machining rostfreier Stahl.

What benefits does the Tiger‑tec Silver coating bring?
Tiger‑tec Silver provides enhanced wear resistance and thermal stability for longer tool life and consistent cutting performance under the demanding conditions of rostfreier Stahl machining.

Is the 0.8 mm corner radius suitable for finishing?
Yes, the 0.8 mm corner radius offers a compromise between edge strength and surface quality, making the insert suitable for finishing and medium‑duty operations.

Can the insert be used for roughing operations?
The geometry and coating support a range of cutting conditions; for heavy roughing, tool selection and parameters should be adjusted accordingly to match the required metal removal rates.
