WNMG 080408 NS520 – Turning insert (trigon) for finishing to light machining, Tungaloy

The WNMG080408 NS520 is an indexable turning insert designed for finishing to light machining of steel, offering a trigon form with an 80° cutting angle and a 0.8 mm nose radius for improved surface integrity.

• Cermet grade NS520 for fine finishing
• Trigon WNMG shape, 80° geometry
• 0.8 mm nose radius for improved surface finish
• Double-sided chipbreaker, cylindrical hole

Improve throughput with a stable cermet grade and consistent wear

The combination of NS520 and a cermet cutting concept focuses on long-term surface finish stability and uniform wear, which supports predictable change intervals and reduced rework. As a finishing-oriented grade, the insert promotes fine surface integrity and dimensional control on light turning operations. The chemistry and microstructure of cermet grades favour abrasion resistance over heavy interrupted cuts, making this grade particularly suitable where consistent part quality and low-rate tool consumption are priorities.

Achieve superior surface finish and dimensional accuracy

A 0.8 mm nose radius together with the trigon form and an 80° cutting geometry reduces cutting vibrations and helps distribute forces across the insert edge, resulting in improved dimensional repeatability and a finer finish. The relatively small nose radius permits tight profile control while still delivering improved aesthetics on turned parts. For customers seeking both form accuracy and a high-quality surface, the geometry balances contact conditions and edge strength during finishing cuts.

Clear guidance on compatibility and secure clamping for reliable results

Belonging to the ISO series of indexable inserts, the trigon WNMG shape is compatible with holders that match the form, relief angle (0°), tolerance class, fastening type, size and thickness. The insert is supplied with a cylindrical hole for location and fastening and has a plate thickness of 4.76 mm, so selection of the correct external holder or boring bar is essential for stable clamping and repeatable positioning. Ensuring holder compatibility avoids runout and secures repeatable tool life in production environments.

Recommended applications and chip control for predictable performance

This insert is optimised for finishing to light machining of steel and is supplied with a double-sided chipbreaker, allowing two usable cutting edges per indexable face and straightforward indexing in case of edge wear. The available option of a coated cermet further enhances edge life and reduces built-up edge tendencies on certain alloys. In practice, the combination of chip control, grade choice and stable seating leads to steady process parameters and reduced downtime for edge changes.

FAQ

What materials is this insert suitable for?
The WNMG080408 NS520 is optimised for finishing to light machining of steel and performs best where surface finish and dimensional accuracy are priorities.

How does the 0.8 mm nose radius affect results?
A 0.8 mm nose radius improves edge contact distribution and reduces vibration, which leads to finer surface finish and more consistent part dimensions when using the insert in finishing operations.

Is the insert indexable on both sides?
Yes, the double-sided chipbreaker design provides multiple usable edges; the WNMG080408 NS520 permits indexing to extend effective cutting life.

Which holder characteristics are required for correct mounting?
Compatibility depends on matching the trigon form, relief angle (0°), tolerance class, fastening type, size and thickness; holders or boring bars designed for ISO WNMG080408 inserts with a cylindrical locating hole are recommended.

What is the manufacturer article number and SKU?
Manufacturer article number 6809665, manufacturer SKU TUN6809665 and SKU 6809665-Tungaloy identify this Tungaloy turning insert.
