TNMG160416‑MM5 WSM20S – Indexable turning insert, Tiger·tec Silver, for stainless steels and superalloys | Walter Tools

A TNMG160416‑MM5 WSM20S indexable turning insert engineered for heavy machining of stainless steels and heat‑resistant superalloys, offering stable edge life under high thermal loads.

Tiger·tec Silver coating for heat resistance
Robust cutting edge with 1.6 mm corner radius
Negative rake 0° for stable roughing cuts
Suited to stainless steels and superalloys

High temperature performance that extends cutting life

The combination of the Tiger·tec Silver technology and the WSM20S cutting grade provides a coated carbide substrate optimised for temperatures and forces commonly encountered when machining stainless steels and superalloys. The advanced coating reduces adhesive wear and supports a stable chip formation, which translates into fewer interruptions for tool changes and more consistent component quality. This results in longer effective tool life and improved process reliability on high‑temperature operations.

Geometry engineered for edge security and predictable results

A triangular 60° shape with a 1.6 mm corner radius and a negative rake of 0° creates a cutting geometry that resists chipping during interrupted cuts and heavy engagement. The MM5 chipbreaker promotes controlled chips even under elevated cutting forces, reducing the risk of built‑up edge and facilitating safer swarf evacuation. These geometry choices make the insert particularly suitable where robustness and repeatable plunge or roughing cuts are priorities, lowering rework rates and enhancing throughput.

Broad material capability with clear application guidance

Designed for ISO groups M and S, this insert covers stainless steels (M) and heat‑resistant superalloys and titanium (S). The specialised WSM20S grade balances hardness and toughness to cope with the high thermal and mechanical loads of these materials, improving resistance to flank and crater wear. For practical application, the insert performs best in heavy roughing and semi‑finishing where thermal stability and edge retention are decisive for cycle time reduction.

Production advantages: compatibility and process security

Available in a compact TNMG form factor and series designation that matches common toolholder systems, this insert offers straightforward integration into existing turning setups. The combination of process security, consistent edge behaviour and a proven chip control design helps to reduce machine downtime and stabilise part quality across batches. Tolerance class M and execution G ensure repeatable fit and positioning, supporting efficient index changes and predictable machining parameters.
