CNMG120404 AH110 indexable insert for turning — PVD-coated carbide, 0.4 mm nose radius (Tungaloy)

The CNMG120404 AH110 is an ISO-standard rhombic indexable insert for turning, designed to deliver a sharp cutting edge and consistent process security in demanding machining operations.

• ISO rhombic insert CNMG 120404 AH110
• PVD-coated carbide for wear resistance
• 0.4 mm nose radius, 80° cutting angle
• Double-sided chipbreaker, cylindrical hole

Consistent cutting performance and reduced downtime

The combination of a PVD-coated carbide grade (AH110) and an optimised geometry provides reliable wear resistance and a sharp cutting edge, which together improve tool life and component consistency. The coating enhances surface hardness and heat resistance, reducing flank wear under cyclic loads; this leads to fewer insert changes and lower downtime in production. For practical planning, the ISO conformity of the rhombic insert simplifies replacement and stock management, because holders that match the CNMG form and ISO size accept the insert without special adapters. The result is predictable performance and a smoother production flow.

Clear guidance on compatibility and mounting

Compatibility with toolholders is determined by the insert form, clearance angle (0°), tolerance class, attachment method, size and thickness; this CNMG geometry suits standard CNMG holders when those parameters match. The insert features a cylindrical locating hole, facilitating secure clamping and precise indexing, and a plate thickness of 4.76 mm with an edge angle of 80°, which together ensure stable seating in the pocket. When ordering, confirm the holder’s seat profile and screw/clamp type to guarantee correct assembly and repeatable positioning; correct mounting reduces vibration and supports surface finishing objectives.

Practical advantages of the grade and chipbreaker selection

The AH110 grade is formulated for chipping resistance and process security, making it appropriate when a sharp cutting edge and reliable performance are both required. The insert’s double-sided chipbreaker offers balanced chip control for many turning tasks, improving chip evacuation and contributing to a steady cutting force that benefits surface quality. Choosing the correct chipbreaker and insert grade according to workpiece material and machine rigidity will extend tool life and reduce scrap rates; where moderate to high stability is available, this turning insert can offer both productivity and dependable repeatability.
