WNMG 080404 AH8015 – ISO turning insert for general turning by Tungaloy

A WNMG080404-PS AH8015 ISO‑standard turning insert designed for external and internal turning of heat‑resistant alloys, combining a PVD‑coated cemented carbide grade with a trigon form for reliable chip control.

• ISO geometry WNMG 080404
• PVD‑coated cemented carbide AH8015
• 0° clearance angle for robust cutting
• Trigon shape with cylindrical locating hole

Predictable performance on heat‑resistant alloys

The PVD‑coated AH8015 grade offers a deliberate balance between wear resistance and cutting‑edge stability, making it a practical choice for demanding turning tasks. The PVD coating improves thermal resistance and reduces built‑up edge when machining high‑temperature alloys, while the cemented carbide substrate sustains mechanical load. This combination leads to fewer interruptions in production and more consistent part quality, particularly when shallow to medium depths of cut are required.

Secure fit and easy integration into ISO systems

Designed to the ISO WNMG geometry, the insert fits standard toolholders when matched for form, size and fastening type. The trigon profile with a cylindrical locating hole provides repeatable positioning, and the specified 0° clearance angle supports robust engagement for conventional turning. Measurable dimensions such as the 08 size and 4.76 mm thickness simplify holder selection and ensure mechanical compatibility across established tool systems, reducing setup time and assembly errors.

Improved surface finish and process stability

A 0.4 mm corner radius offers a compromise between strength at the cutting edge and the ability to achieve improved surface finishes; the slightly rounded corner distributes cutting forces and lowers the risk of chipping. Combined with the PS chipbreaker, the insert promotes consistent chip control for both external and internal turning operations. Overall tool life benefits from the grade and coating synergy, while stable chip evacuation reduces cycle variability and enhances productivity.

FAQ

Which materials are best machined with this grade?
The Tungaloy WNMG080404-PS AH8015 insert is optimised for heat‑resistant alloys, providing a balanced combination of wear resistance and edge stability for alloys that demand elevated thermal performance.

Is this insert compatible with standard ISO WNMG holders?
Yes; the insert follows the ISO WNMG080404 form and is compatible with holders that match the specified geometry, thickness and fastening design, ensuring reliable clamping and repeatable positioning.

What does the PS chipbreaker provide in practice?
The PS chipbreaker on the WNMG080404-PS supports controlled chip formation and evacuation, which helps maintain surface quality and reduces the risk of chip entanglement during continuous turning.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius increases edge strength and promotes a smoother surface finish on finished parts, while also offering improved resistance to chipping under moderate cutting forces.

Can the insert be used for both external and internal turning?
Yes; the WNMG080404-PS AH8015 is suitable for both external and internal turning when paired with an appropriate external holder or boring bar and when machining parameters are adjusted to the application.
