WNMG 080404 AH8015 ISO turning insert for Drehen – Tungaloy, PVD-coated carbide, HRF chipbreaker

The WNMG 080404 AH8015 is an ISO-standard indexable turning insert intended for general-purpose external and internal turning of heat-resistant alloys.

• PVD-coated carbide grade AH8015
• HRF chipbreaker for stable chip control
• Trigon shape, 0.4 mm corner radius
• 0° relief angle and cylindrical hole

Consistent performance for heat-resistant alloys

The insert combines a PVD-coated surface with a carbide substrate to deliver a balance between wear resistance and cutting-edge stability. This composition makes it a reliable choice for machining heat-resistant alloys, where tool life and consistent dimensional results matter. The AH8015 grade is optimised to resist abrasive wear while maintaining a robust cutting edge, so the result is fewer tool changes and steadier cycle times. The HRF chipbreaker aids controlled chip formation, reducing interruptions and protecting the workpiece finish.

Secure fit and predictable compatibility

Compatibility with the toolholder is determined by a set of measurable parameters: ISO form, relief angle, tolerance class, attachment method, size and thickness. The insert’s trigon form and the presence of a cylindrical hole ensure reliable seating and repeatable clamping when matched to an appropriate external holder or boring bar. Choosing the correct holder that accepts the 08 size and the specified 4.76 mm plate thickness simplifies setup and minimises vibration, which in turn improves surface quality and tool lifetime.

Practical benefits from geometry and grade

A 0.4 mm corner radius offers a pragmatic compromise between edge strength and the ability to deliver an acceptable surface finish on varied workpiece geometries. The effective 0° relief supports positive cutting action suitable for general turning operations and helps maintain stability under interrupted cuts. These geometric choices mean fewer rejects, predictable tool change intervals and improved process reliability — translating directly to lower overall production costs and better throughput.

Selection and process guidance

When integrating the insert into a production process, pair the PVD-coated AH8015 grade with cutting parameters suited to heat-resistant alloy machining: moderate depths of cut and speeds that favour edge life over raw material removal. The HRF chipbreaker should be selected where short, controlable chips are required to avoid entanglement in automatic machines. For bespoke recommendations or to verify holder compatibility, consult technical data sheets or contact the supplier to confirm tolerance classes and clamping details.

FAQ

What materials is this insert best suited for?
The WNMG 080404 AH8015 insert is designed primarily for machining heat-resistant alloys; the AH8015 PVD-coated carbide grade balances wear resistance and edge stability for such materials.

How does the HRF chipbreaker affect chip control?
The HRF chipbreaker on the WNMG080404-HRF helps form short, controllable chips, improving operational safety and reducing the need for chip handling during continuous turning work.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, attachment method, size and thickness; match a holder that accepts 08 size, trigon geometry and 4.76 mm plate thickness for reliable clamping.

Is the insert suitable for interrupted cuts?
Yes, the combination of AH8015 grade and a 0.4 mm corner radius provides edge strength that copes well with light to moderate interruptions in turning operations.

What is the benefit of the PVD coating on this turning insert?
The PVD-coated surface increases wear resistance at elevated temperatures and supports longer tool life under the thermal loads typical of heat-resistant alloy machining.
