TNMG220408-RM5 WMP30G indexable turning insert, Tiger‑tec Gold, for stainless steels — Walter Tools

TNMG220408-RM5 WMP30G is a triangular indexable turning insert designed for medium to robust machining of stainless steels, combining a wear‑resistant coating and a chipbreaker tailored to secure chip formation.

• Tiger‑tec Gold coating for stable cutting edges
• Optimised RM5 chipbreaker for secure chip control
• 0° negative rake for robust cutting conditions
• Triangular 60° form with 0.8 mm corner radius

Consistent performance for demanding stainless‑steel turning

The TNMG220408-RM5 WMP30G insert pairs Tiger‑tec Gold technology with a coated carbide substrate to deliver improved wear resistance under the high temperatures typical of machining stainless steels. The coating reduces adhesive built‑up on the cutting edge and helps maintain a stable cutting edge over longer tool life, which in turn supports repeatable component tolerances and fewer interruptions in production. For operations where thermal load and material ductility cause smearing or edge build‑up, this insert offers a measurable uplift in process reliability.

Secure chip control and edge strength that protect cycle times

The integrated RM5 chipbreaker has been developed to control chip form during middle to heavy cuts, reducing the risk of tangled chips and supporting safe evacuation in turning operations. Combined with a 0° negative rake, the geometry favours a stronger cutting edge and higher mechanical stability when facing interrupted cuts or hard inclusions. The 0.8 mm corner radius provides additional edge reinforcement, which improves resistance to chipping and extends usable life under robust conditions — a practical advantage when aiming to keep cycle times tight and scrap rates low.

Practical advantages for shop floor integration and set‑up

The triangular 60° form gives three usable cutting edges per indexable insert, improving economy of use. The insert’s nominal size and thickness support standard toolholder configurations, simplifying inventory and changeover. Although designed for stainless steels, the substrate and chip control characteristics make it suitable in mixed‑material production lines where reliable edge integrity and predictable wear behaviour are priorities. When selecting insert grades or setting feeds and speeds, the combination of Tiger‑tec Gold and RM5 allows a balanced approach between cutting performance and tool‑life optimisation.

How the coating and geometry translate into measurable benefits

In practice, the Tiger‑tec Gold coating reduces adhesive wear and maintains micro‑edge integrity, which improves surface finish and dimensional repeatability. The RM5 chipbreaker promotes short, controllable chips that minimise entanglement and protect toolholders and workpiece surfaces. Together these features deliver higher first‑pass yields and lower rework. For engineers seeking process security and predictable tool replacement intervals, the insert’s construction supports consistent results across batch runs without complex cooling strategies.

The Walter brand is globally recognised for high process safety and consistent tool performance; the Tiger‑tec Gold family addresses the specific challenges of machining austenitic and other stainless steels by combining a robust coating system with geometries designed for secure chip control and long tool life. The Walter AG (brand appearance: Walter Tools) with headquarters in Tübingen is one of the world’s leading manufacturers of precision tools for metalworking.

FAQ

What steels is this insert intended for?
The TNMG220408-RM5 WMP30G insert is specified for stainless steels (material group M) and is engineered to manage the thermal and adhesive behaviour typical of these alloys.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes controllable chip forms and safer evacuation during turning; on the WMP30G grade it contributes to reduced build‑up and more consistent surface results.

Is the 0° negative rake suitable for interrupted cuts?
Yes, the negative rake geometry increases edge strength and mechanical robustness, making it appropriate for interrupted or heavy cutting conditions where edge protection is required.

How many edges are available per insert and what is the corner radius?
The triangular 60° shape provides three usable cutting edges per insert, each with a 0.8 mm corner radius to improve resistance to chipping.

Where can cutting data and supply be obtained?
Cutting data sheets and availability details for Walter Tools Tiger‑tec Gold inserts can be requested from Metav Werkzeuge; they provide application advice and batch supply information.
