CCMT120408-E47 WSM30S – Drilling/bore-enlarging indexable insert, Tiger·tec Silver by Walter Tools

The CCMT120408-E47 WSM30S is a rhombic 80° indexable insert designed for drilling and bore-enlarging applications, optimised for rostfreier Stahl and heat‑resistant superalloys under demanding cutting conditions.

• Tiger·tec Silver coating for high wear resistance
• Suitable for rostfreier Stahl and superalloys
• Rhombus 80° form with 0.8 mm corner radius

Consistent performance for demanding materials

The Tiger·tec Silver grade WSM30S is a coated carbide developed for machining rostfreier Stahl and high‑temperature alloys (ISO groups M and S). This combination of substrate and coating promotes stable chip formation and reduces the risk of built‑up edge on the cutting zone, which directly supports repeatable cycle times and improved surface quality. The medium tolerance class and coated microstructure are focused on balancing tool life and edge robustness in interrupted or high thermal‑load operations.

Geometry and chip control that stabilise processes

The Rhombus 80° form and chipbreaker E47 are matched to provide predictable cutting behaviour in drilling and bore‑enlarging heads. A 0.8 mm corner radius increases edge strength where radial loads and entry conditions are variable, while the 7° free angle assists penetration and reduces rubbing at the flank. Together, these features improve dimensional stability of the bore and help maintain tool integrity under varying depths of cut.

Coating technology that extends usable life

Tiger·tec Silver coating confers thermal and wear resistance suited to materials that conduct heat poorly and strain the cutting edge. The WSM30S grade is described as a coated carbide designed to maintain a sharp, stable cutting edge for longer periods, which can translate into fewer indexings and lower tooling change frequency. This effect supports higher uptime in serial production and contributes to overall process economy.

Practical application and setup guidance

Inserts of this type are typically used in dedicated drill or enlargement tool bodies where insert clamping and coolant delivery are adjusted for M/S materials. The designation indicates a plate size of 12 and a plate thickness of 04, compatible with toolholders matching the CCMT geometry. For reliable results, select feeds and speeds appropriate for rostfreier Stahl and superalloys, monitor cutting temperature, and ensure coolant or lubrication is applied according to the workpiece material and machining strategy.

For reliable machining of rostfreier Stahl and superalloys, request CCMT120408-E47 WSM30S Tiger·tec Silver inserts from Metav Werkzeuge and obtain customised cutting data from the Metav Werkzeuge team.

FAQ

What materials is this insert suitable for?
The insert is specified for rostfreier Stahl (ISO group M) and heat‑resistant superalloys or titanium (ISO group S); the WSM30S grade and Tiger·tec Silver coating are selected to cope with the thermal and adhesion challenges these materials present.

How does the chipbreaker E47 help in drilling operations?
The E47 chipbreaker is designed to control chip form in high‑thermally loaded cuts, promoting stable evacuation and reducing the chance of long, tangled chips in bore‑enlarging heads.

What are the key geometry parameters to consider when selecting this insert?
Important parameters are the Rhombus 80° form for clamping stability, 0.8 mm corner radius for edge strength, and a 7° free angle that reduces flank rubbing during entry and exit phases.

Can the insert be used in interrupted cutting or entry conditions?
Yes, the combination of a robust corner radius and a coated carbide grade supports interrupted cuts; however, toolholder rigidity and correct clamping are essential to achieve expected performance.
