CNMG190616 AH120 Tungaloy turning insert — PVD-coated carbide, 80° rhombic

CNMG190616 AH120 Tungaloy insert is an ISO-format, rhombic turning insert engineered for external and internal turning where a sharp cutting edge and consistent process security are required.

• ISO CNMG190616 rhombic insert, 80° geometry
• PVD-coated carbide AH120 for wear resistance
• Double-sided chipbreaker for reliable chip control
• 1.6 mm corner radius, 6.35 mm thickness

Consistent performance through a wear-resistant cutting grade

The core advantage of this insert is the AH120 PVD-coated carbide, which combines a wear-resistant coating with a robust substrate to reduce flank and crater wear under continuous use. The result is predictable tool life and fewer unexpected interruptions in production, which supports higher overall productivity. By choosing this coated carbide grade, machining stability is improved where a sharp, defined cutting edge and resistance to chipping are required for reliable turning operations.

Simplified holder compatibility and secure mounting

Designed to ISO dimensions, the rhombic shape and 80° geometry make the insert compatible with a wide range of standard turning holders. The design includes a cylindrical locating hole and a 6.35 mm plate thickness, which together determine clamping fit and positional tolerance. These measurable parameters—size 19 and a 1.6 mm corner radius—ensure easier selecting of a matching holder and predictable set-up, reducing changeover time and calibration efforts in the workshop.

Improved chip control and surface quality

The double-sided chipbreaker is engineered to manage swarf formation in both light and interrupted cuts, promoting consistent chip formation and evacuation. That controlled chip flow decreases the risk of re-cutting and supports a better surface finish with fewer passes. For external and internal turning tasks, pairing the chipbreaker style with the AH120 grade helps maintain process security when working with varying material types and differing machine stability.

Practical considerations for application and setup

This insert is intended for turning operations where a sharp edge and reliable performance are required; the ISO specification clarifies form, clearance, tolerance class and fixation for straightforward selection. The zero-degree relief angle and the rhombic profile suit a range of feeds and depths of cut; however, matching the insert sort and chipbreaker to the workpiece material and machine setup is recommended to exploit the grade’s full benefits. The insert is double-sided, offering cost-effective indexing and simple inventory handling.
