TNMG160412-RM5 WMP20S — indexable turning insert, Tiger‑tec Silver, for rostfreier Stahl (Walter Tools)

TNMG160412-RM5 WMP20S is an indexable turning insert designed for robust machining of rostfreier Stahl with a Tiger‑tec Silver coated grade and an RM5 chipbreaker

• Tiger‑tec Silver coating for tough conditions
• Optimised for rostfreier Stahl machining
• Triangular 60° insert with 1.2 mm radius
• RM5 chipbreaker for stable chip control

Reliable cutting performance for rostfreier Stahl components

The combination of the WMP20S grade and the Tiger‑tec Silver coating delivers improved wear resistance and predictable cutting-edge behaviour when machining rostfreier Stahl. The coated cemented carbide substrate reduces the tendency for built-up edge formation and helps maintain a consistent cutting edge under the increased heat and toughness typical of these alloys. With the RM5 chipbreaker, chip form and evacuation are stabilised, which minimises interruption and contributes to higher machine uptime while preserving component surface integrity.

Process security and productivity in production environments

Designed for repeatable, industrial use, the triangular TNMG geometry offers three usable cutting corners per insert and a compact footprint suited to turning operations with limited tool overhang. The negative 0° rake increases robustness for medium to heavier cuts, while the corner radius 1.2 mm balances edge strength with surface finish. These engineered properties translate into fewer tool changes and a more predictable machining cycle, supporting efficient batch production and reduced auxiliary costs.

Practical guidance for application and set-up

The insert is supplied in the standard TNMG format and a 16 mm inscribed circle with 4 mm thickness, making it compatible with a broad range of turning holders that accept TNMG inserts. For finishing to medium machining of rostfreier Stahl, the RM5 chipbreaker promotes short, controlled chips; for tougher interrupted cuts, the negative rake and robust grade improve chip control and protect the edge. Select clamping and coolant strategies that favour consistent thermal conditions to fully exploit the coated grade’s advantages.

FAQ

What materials is this insert suitable for? The TNMG160412-RM5 WMP20S insert is formulated primarily for machining rostfreier Stahl; the WMP20S grade and Tiger‑tec Silver coating are matched to the toughness and thermal behaviour of these alloys.

How does the RM5 chipbreaker affect machining? The RM5 chipbreaker on this insert produces controlled, short chips when cutting rostfreier Stahl, improving chip evacuation and reducing the risk of re-cutting or surface damage during turning operations.

Can the insert withstand interrupted cuts? Yes. The negative 0° rake and the robust geometry of the TNMG indexable insert increase edge strength and resistance to shock, making it better suited to occasional interrupted cutting than inserts with a positive rake.

What benefits does the Tiger‑tec Silver coating provide? Tiger‑tec Silver enhances wear resistance and thermal stability of the coated cemented carbide substrate, extending cutting-edge life and promoting consistent surface quality in rostfreier Stahl machining.

Which toolholders are compatible with this insert? Standard toolholders that accept TNMG inserts with a 16 mm inscribed circle and 4 mm thickness will be compatible; for optimal results, match the holder geometry and clamping to the intended depth of cut and feed.
