WNMG 080408 NS520 — WNMG080408-TS trigon turning insert (Cermet) by Tungaloy

The WNMG080408-TS NS520 is an ISO-standard trigon turning insert designed for finish to light machining of steel in external and internal turning applications

• ISO WNMG trigon for precision turning
• NS520 cermet grade for superior finish
• 0° rake angle for consistent cutting
• Corner radius 0.8 mm for fine detail

Delivering repeatable surface quality and dimensional control

The WNMG080408-TS NS520 is designed to support finish turning where surface integrity and tolerance adherence are decisive. The combination of a cermet NS520 substrate and a finely tuned TS chipbreaker reduces built-up edge and promotes even wear, which in turn maintains component geometry over longer tool life. For machines with stable setups, the insert helps to achieve consistent Ra values while keeping rework rates low. The standardised geometry supports predictable insert seating and repeatable indexation in approved toolholders.

Compatibility and clamping: check form, angle and tolerance

Compatibility depends on insert form, relief angle, 0° rake angle and tolerance class; the trigon format requires matching trigon holders or appropriate boring bars. The WNMG format and the trigon plate form mean that correct clamping and support under the insert pocket are essential for vibration damping and edge life. The presence of a cylindrical hole eases positive locating in compatible clamping systems. Operators should verify holder radius, screw length and seat condition to ensure full contact and reliable performance.

Material behaviour and cutting performance of NS520 cermet

The NS520 grade is a cermet optimised for finishing steels, offering a balance between hardness for wear resistance and toughness for edge stability. Compared with conventional cemented carbide, this grade provides improved surface finish and steadier dimensional behaviour at lower to moderate cutting speeds. The TS chipbreaker is engineered to produce short, controllable chips in finishing passes, reducing the risk of surface damage and improving process cleanliness. For light roughing follow-up with small depth of cut, this insert maintains edge sharpness and delivers predictable flank wear patterns.

Practical recommendations for process integration

Select the TS chipbreaker and corner radius 0.8 mm when the priority is fine detail and tight tolerances; smaller radii reduce cutting forces and improve local finish but require rigid setups. Ensure the toolholder supports the insert across its seating plane and that the fastening torque matches holder specification. When integrating into a production cell, document the insert orientation, clamping parts and index sequence to preserve interchangeability. For atypical materials or unstable setups, choose a different grade or increase clamping rigidity to maintain the intended performance.

FAQ

What materials is this insert best suited for?
The WNMG080408-TS NS520 is intended primarily for finishing and light machining of steel, where the NS520 cermet grade improves surface quality and dimensional stability.

How does the TS chipbreaker affect machining?
The TS chipbreaker on the WNMG080408-TS NS520 produces controllable, short chips in finishing passes, which helps protect the machined surface and maintain steady cutting forces.

Which holders are compatible with this trigon insert?
Compatibility requires holders designed for WNMG trigon inserts; ensure the holder matches the trigon seat, accommodates the cylindrical hole and provides adequate support for the 4.76 mm plate thickness.

Is the NS520 grade suitable for high-speed cutting?
The NS520 cermet is optimised for finish to light machining; while it offers excellent surface finish and wear characteristics, process parameters should be validated for specific machine power and setup stability before high-speed application.
