WNMG 080408 AH8015 — ISO turning insert, trigon 80°, PVD‑coated carbide (Tungaloy)

The WNMG080408-TSF AH8015 is an ISO‑standard trigon turning insert engineered for external and internal turning of heat‑resistant alloys, offering a balanced mix of wear resistance and cutting‑edge stability.

• PVD-coated carbide grade AH8015
• Trigon profile, 80° cutting angle
• Corner radius 0.8 mm for edge stability
• Suitable for heat‑resistant alloys
• ISO 080408 format, 4.76 mm thickness

Stable cutting performance for demanding alloys

The combination of PVD‑coated surface treatment and carbide substrate in grade AH8015 delivers a reliable balance between abrasion resistance and edge strength. In practice this means longer tool life and fewer index changes when machining heat‑resistant alloys, where thermal loads and adhesion can rapidly degrade ordinary grades. The coating reduces built‑up edge formation and supports higher cutting speeds while maintaining dimensional consistency, which contributes to improved process efficiency and lower overall production cost.

Clear guidance on holder compatibility and mounting

The insert follows the ISO 080408 specification, so compatibility with a compatible holder depends on the insert form, trigon profile, 0° relief angle, tolerance class, fastening method, size and thickness. Correct seating and clamping are essential: the cylindrical hole must match the seat and screw system of the chosen outer holder or boring bar. Selecting the correct tolerance class and clamping components reduces vibration and improves repeatability, making the system more robust in series production.

Geometry and how it affects machining results

An 80° approach angle combined with a 0.8 mm corner radius supports a strong cutting edge that resists chipping during interrupted cuts and light roughing. The 4.76 mm thickness of the plate increases rigidity compared with thinner formats, helping to maintain surface finish and bore tolerance when turning under moderate overhang. These geometric traits translate directly into consistent part quality and reduced scrap rates when the machining setup is adjusted to the material and stability of the workpiece.

Chip control and application recommendations

The TSF chipbreaker is designed to provide controlled chip formation when machining tougher, temperature‑sensitive alloys. For best results, match the chipbreaker and grade to the workpiece material and the machine‑tool rigidity: more stable set‑ups permit higher feed and speed settings, while less rigid arrangements benefit from reduced depth of cut and conservative parameters. The balanced properties of this grade aid operators in achieving both process reliability and improved productivity across a range of turning tasks.

FAQ

What materials is this insert best suited for?
The WNMG080408-TSF AH8015 insert is optimised for heat‑resistant alloys, offering a balanced combination of wear resistance and edge strength for challenging materials.

How does the TSF chipbreaker influence performance?
The TSF chipbreaker promotes controlled chip formation under higher thermal loads, improving chip evacuation and supporting stable cutting when machining the specified alloys.

Will this insert fit existing ISO holders?
Compatibility follows the ISO 080408 format, but final fit depends on holder form, relief angle, tolerance class, clamping method, size and thickness; check these parameters before installation.

What is the effect of the 0.8 mm corner radius in operation?
A 0.8 mm corner radius provides a robust cutting edge that resists chipping during interrupted or semi‑roughing cuts while still allowing acceptable surface finish when feeds are chosen appropriately.

Can the grade AH8015 be used at higher cutting speeds?
The PVD‑coated AH8015 grade supports elevated cutting speeds compared with uncoated grades, but optimal parameters depend on machine rigidity, workpiece stability and coolant strategy; adjust settings to the specific application.
