Engineered for demanding materials to reduce process variation

The WSM01 grade, part of the Tiger-tec Silver family, is a coated carbide formulation developed for high thermal and mechanical loads encountered when machining rostfreier Stahl and heat-resistant alloys. This insert combines a thermally stable coating with a substrate engineered for edge strength, which reduces the risk of built-up edge and premature failure. As a result, the machining process becomes more predictable: tool life is stabilised and rework due to edge degradation is reduced. For production environments where repeatable component quality matters, the material and coating pairing offers a measurable improvement in process consistency and surface integrity.

Geometry and chip control focused on productivity

The Rhombus 80° plate form, with a compact 0.4 mm corner radius and an 11° clearance angle, gives a balanced combination of access and strength for drilling and counterboring tasks. The insert’s MM4 chipbreaker is configured to produce short, manageable chips even under interrupted cuts and variable feeds, improving evacuation in deep or constrained holes. This geometry supports stable cutting forces and lowers vibration risk, which in turn helps to maintain dimensional accuracy and surface finish. For mixed-batch production where tool change intervals and downtime affect throughput, the design reduces process interruptions and contributes to higher net productivity.

Greater process efficiency through wear-resistant construction

Thanks to the coated carbide base and the WSM01 formulation, the insert shows good resistance to abrasive and adhesive wear typical of tough alloys and rostfreier Stahl. The robust edge preparation and coating adhesion reduce flank wear progression, extending effective cutting life and lowering the frequency of index changes. From a cost-efficiency perspective, extended tool life and fewer interruptions translate into improved machine utilisation and lower per-part tooling costs. Where cycle time and repeatability are priorities, integrating these inserts can be part of a broader strategy to raise throughput without sacrificing component quality.

Practical compatibility and application guidance

The insert is intended for applications that require controlled cutting in materials classified under ISO group M (rostfreier Stahl) and S (heat-resistant superalloys and titanium). The T-geometry and compact plate size allow use in a variety of toolholders for drilling and counterboring operations. When programming feeds and speeds, prioritise stable chip formation and moderate cutting depths to exploit the MM4 chipbreaker’s strengths. For high-temperature alloys, slower speeds with steady feeds often allow the coated substrate to perform optimally, whereas for some rostfreier Stahl operations a slight increase in feed can help prevent workpiece material from smearing on the cutting edge. Where process windows are narrow, a short trials phase with data logging is recommended to define the optimal parameters for repeatable results.

FAQ

What materials is this insert best suited for?
The CPGT09T304-MM4 WSM01 insert from Walter Tools is formulated for machining rostfreier Stahl and heat-resistant superalloys, combining a coated carbide grade with geometries optimised for secure chip control.

How does the MM4 chipbreaker affect machining performance?
The MM4 chipbreaker produces compact chips and stabilises cutting forces, improving chip evacuation and reducing the risk of re-cutting, which benefits hole quality and tool life when machining stubborn materials.

Is this insert compatible with standard drilling holders?
Yes, the Rhombus 80° form and T3 thickness fit common indexable insert holders for drilling and counterboring, provided the toolholder supports the CPGT09T304-MM4 geometry.

What benefits does the Tiger-tec Silver series provide?
The Tiger-tec Silver coating enhances thermal resistance and reduces adhesive wear, enabling longer effective tool life and more consistent performance during challenging cuts in rostfreier Stahl and similar alloys.

Can the WSM01 grade be used for titanium?
WSM01 is suitable for certain applications in titanium and other high-temperature materials (ISO group S), but parameters should be adapted—slower cutting speeds and optimised feeds—to match the specific alloy and geometry.
