CNMG120416-MM5 WMP20G indexable turning insert — Tiger‑tec Gold coating, for stainless steel (Walter Tools)

CNMG120416-MM5 WMP20G is an indexable turning insert tailored for medium to robust machining conditions in stainless steel, offering a compact Rhombus 80° geometry and a 1.6 mm corner radius.

• Tiger‑tec Gold coated carbide grade WMP20G
• Optimised chip control MM5 geometry
• 0° negative rake for stable cutting
• Suitable for stainless steel (ISO M)

Consistent cutting performance with advanced coating and grade

The combination of the WMP20G grade and the Tiger‑tec Gold coating delivers a balance of wear resistance and heat tolerance suited to stainless steel. Coated carbide in this class supports stable cutting edges and reduces the risk of built‑up edge formation, which is a common challenge with austenitic and work‑hardening alloys. The result is more predictable tool life and more consistent surface quality over extended production runs, improving process reliability and lowering the overall machining cost per component.

Better chip control and effective edge geometry

The MM5 chipbreaker has been developed for secure chip formation when working with tough materials. Paired with the Rhombus 80° form and a 1.6 mm corner radius, the insert offers a compromise between edge robustness and accessibility for a variety of turning tasks. The 0° negative rake increases cutting edge strength and helps maintain stability under moderate to heavy cutting parameters; this makes the insert especially suitable for operations where interrupted cuts or variable depths of cut occur. These geometric choices translate directly into fewer tool changes and less downtime.

Versatile use and process advantages for production workshops

Designed for standard indexable holders, the insert’s dimensions and shape support easy integration into existing tooling systems. The material classification M indicates a focus on stainless steel (ISO M), so the insert performs reliably across common stainless families that tend to work‑harden. For production environments the Tiger‑tec Gold technology contributes to reproducible results and consistent surface finish, enabling shops to maintain throughput while keeping quality stable. The design therefore supports efficient workflows and dependable component tolerances.
