VBMT160408-MM4 WMP20G turning indexable insert – for stainless steel (Tiger‑tec Gold) by Walter Tools

The VBMT160408-MM4 WMP20G is a rhombic 35° turning insert designed for medium to robust stainless steel operations, offering secure chip formation and sustained edge life.

• Tiger‑tec Gold coating for extended tool life
• WMP20G grade optimised for stainless steel
• Rhombic 35° geometry with 0.8 mm corner radius
• MM4 chipbreaker for stable chip control

Precision performance for stainless steel turning

This insert delivers consistent cutting results in demanding conditions thanks to the combination of a coated carbide grade and geometry tuned for long cuts. The WMP20G composition, part of the Tiger‑tec Gold series, is formulated to manage the particular tendencies of stainless steel such as high toughness and built‑up edge formation; this reduces unplanned tool changes and helps maintain cycle time. The design supports a reliable surface finish while allowing stable feeds and depths of cut that are typical in production turning tasks.

Coating and material that reduce wear and increase uptime

The Tiger‑tec Gold coating is engineered to lower flank wear and delay crater formation under elevated temperatures, which directly contributes to extended tool life and fewer insert changes. As a coated carbide solution, the grade provides improved adhesion resistance and thermal stability compared with uncoated grades, meaning the cutting edge remains effective for longer in stainless applications. For workshops seeking predictable tool performance, these material benefits translate into greater process stability and more consistent part quality.

Geometry and chip control for safer, cleaner machining

A rhombic 35° form with a 0.8 mm corner radius and a 5° relief angle gives a balanced mix of cutting strength and accessibility in shoulder and facing operations. The integrated MM4 chipbreaker promotes segmented chips and reduces the risk of long, tangled swarf, supporting safer machine operation and simpler chip handling. In practice, the combination of insert geometry and chip control helps to achieve reliable dimensional repeatability and improved productivity across batch sizes.
