VBMT160408-MM4 WSM30S indexable turning insert — Tiger·tec Silver, Walter Tools

The VBMT160408-MM4 WSM30S is an indexable turning insert engineered for demanding turning of stainless steel and heat-resistant superalloys, offering stable cutting edges and consistent chip formation in high-thermal-load operations.

• Tiger·tec Silver coating for thermal stability
• Optimised chip control with MM4 chipbreaker
• Rhombic 35° geometry for versatile turning
• 0.8 mm corner radius for edge strength

High‑temperature performance and process reliability

The combination of Tiger·tec Silver coating and the WSM30S grade delivers improved wear resistance under thermal stress, making this insert particularly suited to machining stainless steel and other difficult-to-machine alloys. The coated carbide substrate supports controlled flank wear and extended tool life, which translates into longer uninterrupted production runs and fewer index changes. Reliable chip control reduces the frequency of process interruptions and contributes directly to consistent cycle times.

Geometry that balances strength and surface quality

A rhombic 35° cutting geometry paired with a corner radius 0.8 mm and a relief angle 5° provides a compromise between cutting-edge robustness and surface finish. The moderate corner radius increases the insert’s resistance to edge chipping when interrupted cuts or heavy cross-sections occur, while the acute geometry helps maintain acceptable surface integrity on rotational parts. For operators, this means fewer rework cycles and more predictable finishing results.

Practical integration and application guidance

The MM4 chipbreaker MM4 promotes short, controllable chips in a range of feeds and depths, simplifying swarf handling in automated turning cells. As a coated carbide insert designed for S / M material groups, it matches applications that require thermal stability and stable cutting edges. The insert is available in the standard VBMT form factor, which facilitates compatibility with many toolholders and clamping systems. For process planning, consider the grade’s emphasis on thermal resilience when specifying cutting speeds and coolant strategies to maximise tool life.
