CNMG120412 AH8005 Tungaloy indexable insert for Turning — PVD-coated, 80° rhombic

CNMG120412 AH8005 Tungaloy insert designed for stable external and internal turning on heat-resistant alloys and hard materials

• PVD-coated carbide grade AH8005
• 80° rhombic geometry with 1.2 mm radius
• Double-sided insert, cylindrical hole
• Suitable for hard and heat-resistant alloys

Longer tool life and consistent performance with PVD-coated carbide

The PVD-coated carbide construction of this insert combines a hard, wear-resistant surface with a tough carbide substrate to extend cutting life under demanding conditions. The AH8005 grade is formulated for machining heat-resistant alloys and other hard materials where elevated temperatures and abrasive wear reduce tool life. PVD (physical vapour deposition) creates a thin, adherent coating that reduces adhesion and oxidation at the cutting edge; as a result, the insert delivers reliable wear control and steadier flank-wear progression, supporting longer uninterrupted production runs and predictable regrinding or replacement intervals.

Geometry and design for stability and surface finish

The 80° rhombic geometry and 1.2 mm corner radius provide a balance between edge strength and versatility across roughing and finishing passes. The plate is double-sided, offering two usable cutting edges per side, and features a cylindrical hole for secure clamping in ISO-compatible holders. A 0° clearance angle and a plate thickness of 4.76 mm contribute to higher rigidity in the cutting zone, reducing vibration and improving surface quality. These design elements result in a stable machining setup that supports tighter tolerances and consistent component finish when paired with an appropriate holder and clamping set.

Practical system considerations and application guidance

Compatibility with a toolholder depends on form, clearance, tolerance class, fastening method, size and thickness; the insert integrates into standard ISO turning systems and is intended for both external and internal turning. The plate’s double-sided chipbreaker layout allows selection of the appropriate chip control for material and cutting conditions, while the AH8005 grade supports processes where thermal and abrasive loads are significant. For inventory planning, note the manufacturer SKU and article identifiers to ensure correct reordering and the presence of matching screws, clamping pads and backup parts in the tool system. For unfamiliar workpieces or unusual setups, consult the technical documentation to select the optimal chipbreaker and cutting data.

FAQ

What materials is this insert suited for?
The CNMG120412 AH8005 Tungaloy insert is intended for heat-resistant alloys and other hard materials; the PVD-coated carbide and AH8005 grade provide wear resistance under high temperatures.

Is the insert compatible with standard ISO holders?
Compatibility is defined by form, clearance angle, tolerance class, fastening, size and thickness; the CNMG120412 is an ISO-design insert and fits holders designed for CNMG plates when specifications match.

How many cutting edges are available per insert?
This design is double-sided, offering multiple usable cutting edges to extend service life before replacement or regrinding.

What benefit does the 1.2 mm corner radius bring?
A 1.2 mm corner radius improves edge strength for interrupted cuts and higher radial engagement, helping to reduce edge chipping while maintaining acceptable surface finish.
