DCMT070208-FW4 WSM30S indexable turning insert, Tiger·tec Silver, Rhombic 55° – Walter Tools

The DCMT070208-FW4 WSM30S is an indexable turning insert engineered for reliable machining of stainless steels and heat-resistant superalloys, combining a thermally resilient coating with a geometry optimised for stable cutting and chip control.

• Tiger·tec Silver coating for thermal resistance
• WSM30S grade for stainless steels and superalloys
• Rhombic 55° insert with 0.8 mm nose radius
• FW4 chipbreaker for stable chip formation

Prolonged edge life with high thermal stability

The combination of the WSM30S cemented carbide grade and the Tiger·tec Silver coating provides enhanced resistance to thermal loading and abrasive wear, which is particularly valuable when machining materials that generate heat or tend to work-harden. For process planners and manufacturing engineers, this translates into fewer tool changes, predictable tool life and reduced downtime. The coating technology supports a stable cutting edge, reducing the risk of built-up edge and ensuring consistent dimensional results across longer production runs.

Consistent chip control and improved surface finish

The dedicated FW4 chipbreaker is designed to produce short, controllable chips when paired with the Rhombic geometry, lowering the likelihood of entanglement and reducing vibration in the cut. Together with the 0.8 mm nose radius and the 7° clearance angle, the geometry promotes a steady cutting action and a superior surface quality, especially in finishing passes. For workshops aiming for reproducible component appearance, these features enable a balance between material removal and fine surface integrity.

Standardised format for simple tooling integration

The ISO designation is DCMT070208-FW4, a common format that fits a wide range of indexable turning toolholders; this simplifies stocking and changeover procedures in production environments. The insert’s Rhombic 55° shape and size designation allow flexible approach angles for both roughing and finishing operations, supporting mixed-production shops that machine stainless steels and high-temperature alloys. Compatibility with standard clamping systems facilitates quick replacement and consistent positioning for repeatable results.

Key parameters for process planning and setup

Essential measurable values support accurate process engineering: clearance angle 7°, nose radius 0.8 mm, insert shape Rhombic 55°, chipbreaker FW4, grade WSM30S and series Tiger·tec Silver. These specifications aid in selecting cutting data, coolant strategy and holder geometry. When programming CAM systems or preparing operation sheets, the predictable behaviour of this insert helps to calculate cycle times and optimise feeds and speeds for both roughing and finishing stages.
