CNMG 120412 AH110 turning insert – PVD-coated carbide, 80° – Tungaloy

CNMG120412 AH110 is an ISO rhombic indexable insert for turning, designed to deliver a sharp cutting edge and reliable process security in general turning operations.

• PVD-coated carbide grade AH110
• Rhombic ISO CNMG 120412 form
• Double-sided chipbreaker for consistent chips
• Central cylindrical hole for secure clamping

High-performance coating and substrate for extended tool life

The combination of a PVD-coated surface with a carbide substrate ensures improved resistance to flank wear and crater wear, which extends tool life under productive turning conditions. The AH110 grade provides a balance between toughness and hardness that reduces the risk of edge chipping while maintaining a sharp cutting edge, resulting in fewer interruptions and more consistent cycle times. For shops prioritising process stability, this grade supports dependable results on a wide range of turning tasks.

Geometry engineered for secure clamping and chip control

The rhombic CNMG form with an 80° included angle offers predictable cutting forces and easy indexability in compatible holders. With a 1.2 mm corner radius and a 4.76 mm thickness, the insert provides a robust edge for medium to heavy cuts while helping to maintain dimensional stability. The insert is delivered with a central cylindrical hole, enabling secure fastening and repeatable seating in standard ISO toolholders. The double-sided chipbreaker simplifies chip formation and evacuation, which reduces the likelihood of built-up edge and improves surface finish on the workpiece.

Practical benefits for production and quality

Adopting this ISO-format insert supports higher uptime through its durable substrate and controlled chip formation, which reduces rework and inspection intervals. The standardisation of size and form streamlines tool inventory and replacement procedures, improving logistical efficiency on the shop floor. When paired with an appropriate external holder and clamping set, the insert helps to deliver consistent surface quality and predictable tool life, making it suitable for a variety of turning applications where process security is essential.
