WNMG 080412 AH120 turning insert (Tungaloy) — PVD-coated carbide, 1.2 mm radius

WNMG 080412 AH120 is an ISO-format trigon insert designed for external and internal turning with a focus on sharp cutting edges and process reliability.

• PVD-coated carbide grade AH120 for wear resistance
• ISO WNMG080412 trigon insert for turning operations
• 1.2 mm nose radius for robust edge strength
• Double-sided chipbreaker and cylindrical hole

Consistent process stability for precision turning

A PVD-coated carbide grade such as AH120 provides a balance between wear resistance and edge toughness, ensuring steady performance in repetitive turning cycles. The insert’s trigon geometry combined with an 80° approach angle supports secure engagement during both external and internal operations, while the specified 0° relief angle maintains the effective cutting geometry for applications where a sharp cutting edge and repeatable results are required. This configuration reduces unexpected tool changes and contributes to a smoother production flow.

Prolonged edge life through geometry and coating

The combination of coating and form extends usable life: the PVD layer decreases abrasive wear and helps prevent built-up edge, while the 1.2 mm nose radius strengthens the cutting edge against chipping under interrupted cuts. A plate thickness of 4.76 mm and a double-sided chipbreaker enhance structural rigidity and allow the insert to be indexed twice, which improves cost-effectiveness per cutting edge. These features translate into fewer tool changes and more predictable component quality across series production.

Fast integration into ISO tooling systems

The ISO-based design ensures compatibility with a wide range of holders when matching is made by form, relief angle, tolerance class, clamping method, size and thickness. The insert is supplied with a cylindrical hole, suitable for positive clamping systems and standard screw or clamp fixtures; a matching shim and screw set complete the typical assembly. Specifying ISO-conformant components simplifies procurement and reduces setup complexity on the shop floor, supporting faster tool changeovers and less downtime.

Best-use recommendations and practical advantages

Choose this insert for turning tasks that demand a sharp cutting edge and a high level of process security. The double-sided chipbreaker allows adaptation to different chip formation needs; select the chipbreaker style and the AH120 grade to match the workpiece material and cutting conditions. For stable, repeatable machining in batch production, the insert’s geometry and coating provide a good compromise between surface finish consistency and tool life, improving throughput and lowering tooling costs over time. The Tungaloy grade is especially useful where predictable performance under varied cutting conditions is a priority.

FAQ

What holders are compatible with this insert?
Compatibility is determined by form, relief angle, tolerance class, clamping method, size and thickness; the WNMG080412 AH120 Tungaloy insert (SKU 6809790-Tungaloy) fits ISO-compatible trigon holders designed for the 08 size and 4.76 mm plate thickness.

For which turning tasks is this grade recommended?
The AH120 PVD-coated grade is intended for turning operations where a sharp cutting edge and stable process behaviour are required, offering improved wear resistance and resistance to chipping in repetitive machining.

What benefits does the PVD coating provide?
A PVD coating on a carbide substrate increases wear resistance and reduces adhesion of material to the cutting edge, which helps maintain surface finish and extend the usable life of the WNMG080412 insert.

How is the insert mounted in the tool assembly?
The insert uses a cylindrical hole for positive clamping; secure the plate with the correct clamp or screw and a suitable shim, ensuring the holder matches the ISO WNMG form and the specified plate thickness.
