TNMG160404-FM5 WMP20G indexable turning insert — Tiger·tec Gold grade for stainless steel — Walter Tools

A TNMG160404-FM5 WMP20G indexable turning insert designed for efficient turning of stainless steel in medium to robust conditions, combining a coated carbide grade with a controlled chipbreaker for stable process behaviour.

• Tiger·tec Gold coating for robust edge life
• FM5 chipbreaker for controlled chip formation
• Optimised for stainless steel (ISO group M)
• Triangle 60° geometry, 0.4 corner radius

Superior chip control for reliable cycle times

The combination of the WMP20G grade and the FM5 chipbreaker provides controlled, short chips and steady removal of material when machining stainless steel. The Tiger·tec Gold coating reduces flank and crater wear under typical stainless-steel cutting conditions, which helps maintain a stable cutting edge and reduces unplanned tool changes. This results in more predictable cycle times and less scrap, supporting higher operational efficiency on turning centres and lathes.

Consistent surface finish through optimised geometry

The triangular 60° insert form, paired with a 0.4 corner radius and 0° (negative) rake, produces a robust cutting edge that resists edge chipping and built-up edge formation. The geometry supports repeatable workpiece accuracy and consistent surface quality even when feeds and depths vary slightly. Such stability is particularly valuable for medium-duty to heavier turning tasks on stainless steel where thermal and mechanical stresses can otherwise degrade finish and tolerance control.

Practical advantages for workshop productivity

Built as a coated carbide, WMP20G targets the specific challenges of stainless steel: toughness, tendency to form built-up edges and elevated cutting temperatures. The insert’s configuration simplifies tool planning—fewer regrinds and predictable edge life lower tooling costs in the mid to long term. For application support or grade comparison, Metav Werkzeuge can provide cutting-data recommendations and help match the insert to the machining strategy, preventing guesswork at setup and accelerating time to first good part.

FAQ

Which materials is this insert intended for?
The TNMG160404-FM5 WMP20G from Walter Tools is intended primarily for stainless steel (ISO group M), offering controlled chip formation and stable cutting-edge behaviour for such alloys.

What benefit does the FM5 chipbreaker provide?
The FM5 chipbreaker promotes short, controllable chips and reduces the risk of entanglement and built-up edge during machining of stainless steel, improving process reliability with the TNMG160404-FM5 WMP20G insert.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating on the WMP20G grade enhances wear resistance and edge stability under the high temperatures typical for stainless steel machining, extending effective tool life and consistency of results.

Is the TNMG160404-FM5 suitable for finishing operations?
With a 0.4 corner radius and triangle 60° form, the insert balances robustness and fineness of cut; it can be used for semi-finishing and general turning where a reliable surface finish is required.
