CNMG 190616 AH120 — ISO indexable turning insert, PVD-coated carbide, 80° lead angle | Tungaloy

A CNMG190616 AH120 indexable turning insert engineered for external and internal turning, featuring a double-sided chipbreaker and a cylindrical hole for reliable clamping in ISO-compatible holders

• ISO CNMG 190616 geometry
• PVD-coated AH120 carbide grade
• 80° lead angle for versatile turning

Consistent process security from geometry and grade

The rhombic insert geometry combined with an 80° lead angle and a 1.6 mm corner radius creates a stable cutting line that reduces vibration and supports predictable tool life. As a PVD-coated carbide grade, AH120 delivers improved resistance to flank wear and chipping compared with uncoated grades; this makes the component especially suited to operations where maintaining a sharp cutting edge and steady cutting conditions is essential. The ISO-standard form ensures straightforward identification and selection for conventional turning applications.

Productivity gains through optimised chip control and mounting

A double-sided chipbreaker in a PVD-coated grade offers controlled chip formation and repeatable surface finish across multiple re-grinds, contributing directly to higher uptime on the machine. The insert thickness of 6.35 mm and a nominal plate size of 19 mm paired with the cylindrical hole and matching clamp set provide secure seating and repeatable clamping forces in the toolholder assembly. The PVD layer enhances thermal and abrasive resistance, enabling higher cutting parameters where the workpiece and machine rigidity allow, thereby improving throughput while maintaining component quality.

Practical selection and system compatibility for efficient tooling

Compatibility with the holder depends on form, clearance angle, tolerance class, fastening, size and thickness; the complete system includes an ISO turning insert, a suitable external holder or boring bar, a shim/clamp set and replacement screws. When processing a variety of steels and alloyed materials, the AH120 grade is a balanced choice for wear and edge stability. For applications requiring different chip control or surface finish, select an alternative chipbreaker geometry or a grade optimised for the specific material; technical data and matching holder recommendations are available to support the tooling decision.

FAQ

What materials is this insert suitable for?

The CNMG190616 AH120 insert is a PVD-coated carbide grade intended for general turning applications and offers robust wear resistance on a wide range of steels and alloyed materials.

How does the 1.6 mm corner radius affect performance?

A 1.6 mm corner radius increases edge strength for interrupted cuts and roughing operations while providing a balance between surface finish and tool life for this indexable insert.

Which holders are compatible with the CNMG190616 geometry?

Compatibility requires an ISO CNMG-compatible holder matched for form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s cylindrical hole and 6.35 mm thickness require corresponding clamping components.

What benefits does the AH120 PVD coating provide?

The AH120 PVD-coated grade enhances resistance to flank wear and chipping, supports sharper cutting edges and contributes to process stability during medium-duty turning operations with improved tool life.

Is this insert single- or double-sided and what does that mean for use?

The insert features a double-sided chipbreaker, allowing rotation to a fresh cutting edge after indexing, which effectively doubles the number of usable edges and supports economical tooling.
