WNMG 080404 AH725 WNMG080404-TM — ISO turning insert, PVD-coated, 0.4 mm radius | Tungaloy

WNMG080404-TM AH725 is an ISO-standard turning insert designed for external and internal turning, optimised for mixed-material production where process security and consistent edge behaviour are required

• ISO tool geometry WNMG form, 80° trigon
• PVD-coated AH725 for process security
• 0.4 mm corner radius for precise finishing

Stable productivity for mixed-material turning

The trigon WNMG geometry with an 80° included angle combines rigidity with accessible cutting edges, enabling steady cutting conditions on a variety of workpieces. The insert is manufactured from carbide (Hartmetall) and finished with a PVD-coated AH725 grade that is engineered for universal, chip-resistant performance on Stahl and rostfreier Stahl. This results in fewer interruptions for edge changes and predictable component tolerances, which supports higher machine utilisation and improved throughput.

Reliable edge control and wear resistance for process safety

The AH725 coating provides enhanced adhesion and edge strength, helping to prevent premature chipping under varying cutting conditions. The 0.4 mm corner radius balances robustness and surface finish, allowing for controlled cutting forces and good dimensional stability. For users seeking straightforward terminology: the PVD layer increases thermal and abrasive resistance, so the insert keeps its geometry longer and maintains machining quality under repeated cycles.

Compatibility and handling that reduce downtime

As an ISO-standard indexable insert, the component fits holders that match form, relief angle, tolerance class, fastening method, size and thickness; the system typically comprises an outer holder or boring bar, a shim/clamp set and spare fastening screws. The insert includes a cylindrical hole for positive locating and secure clamping, which simplifies indexing and replacement. Specifying the correct chipbreaker and grade for the workpiece and machining strategy ensures process reliability and efficient tool consumption.

FAQ

Is this insert suitable for both external and internal turning?
The WNMG080404-TM AH725 insert is designed for both external and internal turning operations and is compatible with ISO-standard holders when the holder form and tolerance match the insert geometry.

Which materials are recommended for the AH725 grade?
The AH725 PVD-coated grade is intended for universal use on Stahl and rostfreier Stahl, offering stable chip formation and reliable edge life in mixed-material production.

What does the TM chipbreaker mean for cutting performance?
The TM chipbreaker is configured to support medium to general-purpose chip control; paired with the AH725 grade it promotes predictable chips and reduced risk of built-up edge in interrupted or varied cutting conditions.

How does the 0.4 mm corner radius affect surface finish and strength?
A 0.4 mm radius provides a compromise between edge strength and achievable surface finish: it improves durability compared with very small radii while still allowing fine finishing strategies when required.

Can the insert be mounted in any WNMG holder?
The insert fits holders that conform to ISO specifications; compatibility depends on matching form, relief angle, tolerance class, fastening and thickness — verify holder specifications before mounting.
