TNMG160408-NMS WSM20S – Turning indexable insert, triangle 60°, Tiger·tec Silver (Walter Tools)

TNMG160408-NMS WSM20S is a triangular indexable insert engineered for secure machining of stainless steels and heat‑resistant superalloys in demanding turning operations

• Tiger·tec Silver coated carbide grade WSM20S
• Optimised for stainless steels and superalloys
• Triangle 60° geometry with 0.8 mm corner radius
• Chipbreaker NMS for controlled chip formation

Proven chip control for difficult-to-machine alloys

The WSM20S grade, applied within the Tiger·tec Silver coating system, is tailored to maintain stable chip formation when machining materials that tend to gall or generate long, stringy chips. The integrated chipbreaker NMS supports uninterrupted removal of swarf, which reduces downtime and improves process reliability. For workshops facing high thermal loads, this insert provides a combination of thermal resistance and edge strength that translates directly into higher productivity and fewer interruptions.

Geometry designed for consistent edge life and surface finish

A triangle 60° form with a 0.8 mm corner radius offers repeatable corner strength and a versatile cutting edge suitable for both roughing and light finishing passes. The negative 0° rake promotes a secure cutting action that helps avoid chatter on unstable setups and contributes to consistent dimensional control. Users benefit from predictable wear behaviour and a better surface quality on components where tolerance and finish matter.

Coating and grade features that extend tool life

The coated carbide construction combines wear-resistant layers with a substrate optimised for toughness, improving resistance to flank and crater wear under intermittent or heavy cutting conditions. The Tiger·tec Silver technology enhances heat management at the cutting zone, which is particularly advantageous when processing stainless steels and titanium alloys that resist heat dissipation. This means longer indexable insert life and fewer insert changes per shift.

Application scope and practical handling

Suitable for machining operations classified under ISO groups M (rostfreie Stähle / stainless steels) and S (heat‑resistant superalloys and titanium), the insert performs well where cutting temperatures and edge stress are elevated. The TNMG form is compatible with standard triangular insert toolholders and is straightforward to seat and clamp, allowing seamless integration into existing turning tool sets. For optimal results, match cutting data to material group and monitor wear for timely index changes.
