WNMG080412-HRM AH8005 ISO turning insert — PVD-coated cemented carbide for stable machining — Tungaloy

The WNMG080412-HRM AH8005 is an ISO-standard trigon turning insert engineered for stable external and internal turning of heat‑resistant alloys and other hard materials.

• PVD-coated cemented carbide grade AH8005
• HRM chipbreaker for controlled chip formation
• Trigon form with 80° cutting angle
• Corner radius 1.2 mm for consistent finish

Stable cutting performance for demanding turning tasks

The PVD-coated AH8005 grade combines a wear-resistant surface with a tough substrate to keep cutting edges intact under elevated temperatures often encountered with heat‑resistant alloys. This composition supports stable machining, reducing the frequency of insert changes and helping to maintain a consistent surface finish across production batches. The HRM chipbreaker is optimised for controlled chip formation, which lowers the risk of rework and contributes to predictable cycle times. For environments where repeatability matters, the combination of coating and geometry directly translates into fewer interruptions and improved throughput.

Designed for secure fitting and precise geometry control

Compliance with ISO dimensions ensures compatibility with standard turning holders, but correct pairing depends on form, clearance angle, tolerance class, clamping method, size and plate thickness. The insert’s trigon shape and cylindrical hole enable reliable mechanical clamping, while the 0° clearance angle and 80° cutting-edge orientation provide predictable cutting forces. The 4.76 mm plate thickness adds rigidity in heavier cuts, and the defined 1.2 mm corner radius balances edge strength with surface quality. When selecting a holder, match these parameters to avoid chatter and ensure the insert performs as intended.

Productivity and lifecycle benefits for the workshop

Using a grade tailored to hard and heat‑resistant materials helps to extend tool life and sustain part quality, which in turn reduces tool consumption and setup time. The insert’s geometry and HRM chipbreaker support efficient chip evacuation, decreasing the likelihood of interrupted machining and saving machine hours. For batch production or mixed‑batch environments where material variety occurs, the robust grade minimises the need for frequent tool changes. Choosing a suitable insert grade and chipbreaker therefore contributes to lower unit costs and a more predictable production rhythm.

FAQ

What materials is the WNMG080412-HRM AH8005 suited to machine?
The WNMG080412-HRM AH8005 is formulated for heat‑resistant alloys and other hard materials where wear resistance and edge stability are required.

Which chipbreaker does this insert use and what is its benefit?
The insert features the HRM chipbreaker, which promotes uniform chip formation and efficient evacuation, supporting stable cutting and consistent surface quality.

How should the insert be matched to a holder?
Compatibility depends on the insert form, clearance angle, tolerance class, clamping method, size and thickness; the WNMG080412-HRM AH8005’s cylindrical hole and trigon form provide secure clamping when matched to an ISO‑compatible holder.

Can the insert be used for internal turning as well as external turning?
Yes — the WNMG080412-HRM AH8005 is suitable for both external and internal turning operations, provided the holder and setup offer the required rigidity.

What does a 1.2 mm corner radius mean for part finish and tool life?
A 1.2 mm corner radius increases edge strength for interrupted cuts and contributes to a consistent surface finish, balancing durability and cosmetic quality.
