CCMT09T304-MM4 WSM30S turning and drilling indexable insert by Walter Tools — Tiger·tec Silver, MM4 chipbreaker

CCMT09T304-MM4 WSM30S is an indexable insert designed for combined drilling/boring and turning applications, optimised for stainless steels and heat-resistant superalloys where heat resistance and edge stability are critical

• Tiger·tec Silver coating for heat resistance
• Optimised MM4 chip control
• Rhombic 80° form for versatile insert use
• 7° clearance with 0.4 mm corner radius

High-temperature performance that stabilises the process

The WSM30S grade from the Tiger·tec Silver series is a coated carbide solution engineered for materials that generate high cutting temperatures and tend to form built-up edge. Its microstructure and coating support a stable cutting edge and reduced adhesion, which in turn lowers the risk of premature wear and unplanned rework. As a result, the insert sustains consistent performance in interrupted cuts and demanding stainless steel operations while maintaining surface integrity.

Geometry and chip control that improve productivity

The Rhombic 80° insert geometry combined with the MM4 chipbreaker provides controlled chip formation across a range of feeds and depths of cut. The 7° clearance and 0.4 mm corner radius help to distribute cutting forces and reduce vibration, delivering a reliable balance between edge strength and surface finish. For shops seeking predictable chip flow and fewer machine stoppages, this geometry reduces manual chip handling and supports smoother cycle times.

Practical specification for stable repeatability and handling

Produced to tolerance class M, the insert’s T3 thickness and size 09 format make it compatible with a wide range of standard toolholders for drilling/boring and turning indexable applications. The combination of grade and form is tailored to deliver process reliability when machining rostfreier Stahl and heat-resistant alloys, offering an economical route to longer tool life and less frequent index changes. The insert’s characteristics simplify setup and reduce inspection time during production runs.

FAQ

Which materials are suitable for this insert?
The CCMT09T304-MM4 WSM30S insert from Walter Tools is intended primarily for rostfreier Stahl (stainless steels) and heat‑resistant superalloys (ISO groups M and S), offering improved edge life in tough, heat‑generating materials.

What benefits does the MM4 chipbreaker deliver?
The MM4 chipbreaker on the CCMT09T304-MM4 WSM30S creates consistent chip segmentation and evacuation, which reduces machine downtime and improves surface finish during turning and drilling operations.

Is the geometry suitable for both turning and boring?
Yes — the Rhombic 80° form and the insert’s dimensions allow versatile use in both drilling/boring and turning applications, providing a balance between cutting edge strength and accessibility in a variety of toolholders.

What does tolerance class M mean for shop practice?
Tolerance class M indicates machining and seating accuracy appropriate for stainless and heat‑resistant materials, supporting repeatable clamping and minimal runout when fitted to compliant toolholders.

How does the Tiger·tec Silver series affect tool life?
The Tiger·tec Silver technology used on WSM30S enhances thermal stability and wear resistance, which typically leads to longer intervals between index changes and more stable performance in high‑temperature cutting scenarios.
