VCMT160408-RM4 WMP20G – indexable turning insert, Tiger‑tec Gold, RM4 (Walter Tools)

A VCMT160408-RM4 WMP20G indexable turning insert engineered for medium to robust machining of rostfreier Stahl with a Rhombus 35° geometry and a 0.8 mm corner radius

• Tiger‑tec Gold coating for improved edge life
• RM4 chipbreaker for stable chip control
• 7° clearance angle for secure engagement
• Rhombus 35° form with 0.8 mm radius

Greater process reliability when machining rostfreier Stahl

The combination of the Tiger‑tec Gold coating and the WMP20G grade is formulated specifically for the challenges of machining rostfreier Stahl. The coating reduces adhesion and thermal load at the cutting edge, which helps to avoid built-up edge and unplanned rework. In practice, this means longer intervals between insert changes and a more predictable component finish. The optimised cutting-grade chemistry supports a broad range of stainless alloys under medium to robust cutting conditions, delivering repeatable results and improved uptime.

Predictable edge life and controlled chips for consistent productivity

With the RM4 chipbreaker and a 0.8 mm corner radius, the insert provides secure edge strength while guiding chips reliably away from the cut. The 7° clearance angle reduces rubbing and heat generation at the flank, contributing to a stable cutting edge and a consistent surface quality. These geometric features together reduce the risk of premature edge failure and make tool-life planning more reliable, which benefits batch production and small-series work alike. The insert’s robust edge geometry supports higher metal-removal rates without sacrificing finish.

Easy integration into existing toolholders and process chains

The Rhombus 35° shape and ISO designation mean straightforward compatibility with standard toolholders used for turning operations. The insert is suitable for applications that demand durability and consistent results in rostfreie Stähle. Technical advisors can supply recommended cutting speeds and feeds for the WMP20G grade to match the specific alloy and machine rigidity. For customers seeking uncomplicated implementation, this grade offers a balance of process security and service life that aligns with production targets.
