WNMG 080404 NS520 — Turning insert WNMG080404-TS by Tungaloy

The WNMG080404-TS NS520 is an ISO-standard turning insert for external and internal turning, optimised for finishing and light machining of steel with emphasised surface quality and dimensional control

• Cermet grade NS520 for superior surface finish
• Trigon WNMG form with 0.4 mm corner radius
• TS wiper chipbreaker for improved machining quality
• ISO-compliant insert with cylindrical hole

Precision finishing and consistent dimensional control

The cermet NS520 grade is designed for finishing to light turning of steel where surface finish and dimensional stability are decisive. Cermet combines ceramic and metallic phases to deliver a hard, wear-resistant cutting edge with reduced built-up edge tendencies; this supports a uniform wear pattern and helps maintain tolerance bands over longer production runs. For operations prioritising quality over aggressive material removal, the choice of a wiper-type chipbreaker and a small corner radius contributes directly to lower rework rates and improved first-pass accept rates.

Standardised geometry for secure mounting and process reliability

The insert follows the ISO WNMG geometry and the trigon plate form, which simplifies holder selection and machine setup in standard turning tool systems. Key geometric parameters such as the 0.4 mm corner radius, 0° relief angle, 80° included angle, size 08 and a plate thickness of 4.76 mm determine compatibility with holders and clamping systems; the insert’s cylindrical hole supports conventional fastening. Observing holder form, tolerance class, fastening method and plate thickness ensures repeatable clamping and consistent cutting conditions, reducing vibration and promoting a stable cutting edge throughout the tool life.

Productivity gains through edge life stability and machining comfort

A combination of a cemented carbide substrate and a cermet cutting grade yields an insert that balances toughness with excellent surface generation. The TS chipbreaker specifically enhances the final surface by smoothing micro-oscillations and producing shorter, more manageable chips in stable setups. In practice, this translates into fewer finishing passes, reduced time for part hand-over, and a more predictable tool change cycle. When matched to the correct holder and machining parameters, the insert supports a productive finishing workflow while preserving component quality and minimising secondary operations.

FAQ

Which workpiece materials are recommended for this insert?

The NS520 cermet grade is recommended primarily for steel in finishing and light turning applications; the grade emphasises surface finish and steady wear behaviour.

What is the role of the TS chipbreaker?

The TS wiper chipbreaker is designed to improve final surface quality by producing shorter chips and smoothing the cut, which supports better surface finish in stable machining setups.

How can compatibility with existing toolholders be verified?

Compatibility depends on holder form, relief angle, tolerance class, fastening method, plate size and thickness; checking these parameters against the WNMG080404-TS ISO geometry ensures secure clamping and correct tool engagement.

How does the 0.4 mm corner radius influence results?

A 0.4 mm radius balances edge strength and surface generation: it improves finish compared with larger radii while still providing adequate edge robustness for finishing cuts.
