TNMG220412 AH120 Tungaloy — Indexable turning insert for Turning, PVD-coated carbide, 60°

The TNMG220412 AH120 is an ISO-compliant, triangular indexable insert designed for both external and internal turning where a sharp cutting edge and high process security are required.

• ISO triangular insert, 60° geometry
• PVD-coated carbide AH120 grade
• Wear- and chip-resistant cutting edge
• Double-sided with 1.2 mm corner radius

Consistent process security for production turning

The supplied insert is an ISO-compliant triangular indexable component engineered for stable metal removal. Manufactured in PVD-coated carbide with the AH120 grade, the geometry prioritises a sharp, wear-resistant cutting edge that maintains performance in continuous operation. For production environments, the combination of coating and substrate reduces flank wear and the risk of edge chipping, which translates into fewer tool changes, predictable component quality and improved machine uptime. The construction is aimed at repeatable results under varying machining conditions, supporting efficient cycle times and consistent surface integrity.

Geometry and radius that improve finish and robustness

A 60° cutting geometry combined with a 1.2 mm corner radius balances edge strength and surface finish: the corner radius reduces edge stress and helps absorb intermittent loads, while the triangular form provides three indexed cutting edges per side where applicable. The insert is double-sided and features a cylindrical hole for secure clamping; its plate thickness of 4.76 mm and plate size of 22 mm contribute to rigidity and minimise vibration during turning. Together, these characteristics help generate a stable chip flow and a reliable surface quality on the workpiece, especially when the selected chipformer matches the material and machining stability.

Compatibility and system integration for straightforward set-up

Compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness; this insert therefore integrates into standard ISO turning systems when matched appropriately. The insert is specified with a 0° clearance angle, a cylindrical mounting hole and the ISO designation TNMG220412, enabling straightforward selection of a suitable external holder or boring bar together with the required underlay/clamping kit and replacement screws. Using components from the same system family or verified holder specifications reduces set-up time and increases clamping reliability during higher material removal rates.

Selecting chipbreaker and grade to suit the job

The double-sided chipbreaker design and the AH120 coating grade make this insert suitable where both a sharp cutting edge and process security are demanded. Choose the chipbreaker and grade that match the workpiece material, machining operation and machine rigidity to obtain the intended benefits: controlled chips, reduced cutting forces and longer tool life. In applications with stable set-up and heavier cuts, the robust corner and coated substrate provide dependable performance; for finer finishing passes, the geometry still supports improved surface quality while preserving edge integrity.

FAQ

What applications is this insert suitable for?
The TNMG220412 AH120 insert is designed for external and internal turning operations where a sharp edge and process security are required.

How does the AH120 grade benefit machining?
The AH120 PVD-coated carbide grade delivers improved wear resistance and reduced chipping, ensuring consistent cutting performance with extended edge life.

Which holders are compatible with this ISO designation?
Compatibility depends on holder form, tolerance class, fastening method and the insert dimensions (22 mm size, 4.76 mm thickness). The TNMG220412 designation fits ISO-standard holders designed for TNMG inserts.

What does the 1.2 mm corner radius affect in practice?
A 1.2 mm corner radius increases edge strength and helps produce a stable finish; it is particularly advantageous for moderate to heavy cuts where edge robustness is important.

How many indexed edges does the insert offer?
The triangular, double-sided design provides multiple usable cutting edges per index. The exact count depends on how the insert is oriented and rotated in the clamping assembly.
