CNMG190616 AH120 indexable turning insert (ISO CNMG190616) — Tungaloy

The CNMG190616 AH120 is an ISO-standard indexable insert engineered for general turning tasks, offering a sharp cutting edge and process security for external and internal machining.

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

Consistent cutting performance for turning operations

The CNMG-family geometry with an 80° rhombic profile and a 1.6 mm corner radius provides a reliable compromise between strength and edge line for a wide range of turning jobs. Manufactured from carbide and finished with a PVD coating, this grade is formulated for improved wear resistance and predictable performance under varying cutting conditions. The specification helps reduce unexpected edge failure and supports repeatable component quality, which is essential for production environments seeking stable cycle times and reduced rework.

Built for edge stability and process security

The AH120 grade is a wear- and breakage-resistant PVD-coated carbide designed to maintain a sharp cutting edge under intermittent or continuous cuts. The insert’s geometry, combined with the double-sided chipbreaker, promotes consistent chip formation and evacuation, lowering the risk of built-up edge and tool overload. For operations prioritising surface finish and tool life, the coated carbide composition and the chip control geometry contribute directly to fewer tool changes and more predictable maintenance intervals.

Compatibility with holders and system requirements

Compatibility with toolholders is defined by the insert’s form, relief (free) angle 0°, tolerance class, mounting style, size and thickness; the CNMG190616 follows ISO standards, so selection of a matching 80° external holder or boring bar is straightforward when these parameters are observed. The insert includes a cylindrical central hole for secure clamping and is intended for use in a system consisting of the indexable insert, appropriate external holder or boring bar, clamping pad/kit and replacement screws. Clear alignment of these dimensions ensures correct seating, repeatable clamping and stable cutting forces during turning.

Practical machining advantages and chip control

With a plate thickness of 6.35 mm and a rhombic plate form, the insert balances rigidity with accessibility in confined diameters and internal bores. The double-sided chipbreaker enables reversible use of both cutting edges, effectively doubling the available edge life and improving cost-efficiency per insert. Additionally, the PVD finish supports sliding contact resistance and helps maintain a consistent cutting geometry over prolonged runs, which benefits batch production and mixed-series manufacturing where repeatable part quality is required.

FAQ

What applications suit this indexable insert best?
The CNMG190616 AH120 indexable turning insert from Tungaloy is intended for external and internal turning operations and is typically used where a sharp cutting edge and process security are required (SKU TUN6811664).

What material and coating are used on this insert?
This insert is manufactured from carbide and finished with a PVD AH120 coating, combining substrate toughness with surface protection for improved wear resistance.

How does the chipbreaker affect machining?
The double-sided chipbreaker offers consistent chip control and enables reversible use of both cutting edges, supporting stable chip formation and extended edge life for longer production runs.

Which dimensions and angles are critical when choosing a holder?
Key dimensions are the 19 mm plate size, 6.35 mm plate thickness, 1.6 mm corner radius, 80° geometry, and 0° relief angle; correct matching of these parameters ensures secure clamping and proper seating in the holder.

Is the insert reversible and how many edges are available?
Yes; the insert is double-sided, allowing use of both edges per side, effectively providing multiple usable cutting edges before replacement.
