TNMG160408 AH120 TNMG turning insert for Drehen — Tungaloy

TNMG160408 AH120 is an ISO-standard triangular turning insert designed for general external and internal turning applications where a sharp cutting edge and process stability are required.

• PVD-coated carbide for stable cutting
• Wear- and fracture-resistant grade AH120
• ISO TNMG160408 triangular insert with hole
• Double-sided chipbreaker, 0° clearance angle

Reliable cutting performance for continuous turning processes

The PVD-coated carbide substrate in this grade delivers a combination of wear resistance and edge stability intended for repetitive turning, making it suitable where consistent component quality is essential. The insert’s geometry — triangular form with a 60° included angle and a 0° clearance angle — supports secure seating in standard ISO holders and a predictable cutting orientation. The double-sided chipbreaker contributes to controlled chip formation, which reduces rework and helps maintain toolpath stability over longer production runs. This results in fewer interruptions for indexing or replacement and supports higher overall machine utilisation.

Efficiency gains through chip control and reduced changeover

A clear, measured benefit of the AH120 grade is improved chip control, which facilitates safer swarf evacuation and minimises the risk of surface damage on workpieces. The PVD layer enhances resistance to abrasive wear while preserving a sharp cutting edge for longer, which translates into extended tool life and lower tooling consumption per part. For operations seeking to lower cycle time variance and improve first-pass yield, the combination of coating, grade and chipbreaker geometry offers a tangible productivity advantage without complex process adjustments.

Seamless integration with ISO toolholding and predictable indexing

As an ISO-series insert, compatibility is governed by form, clearance angle, tolerance class, fastening, size and thickness; the TNMG160408 AH120 is supplied with a cylindrical hole for positive clamping and a plate thickness of 4.76 mm that matches common ISO TNMG pockets. The triangular shape provides multiple indexing positions, making the insert an economical choice where repeatable seating and quick index changes are required. For complex setups, reference the holder’s specification sheet to confirm matching tolerance classes and clamping hardware — this approach ensures reliable seating and repeatable part tolerances during production.

Durable grade selection for demanding process requirements

The AH120 designation denotes a wear- and fracture-resistant turning grade that balances edge sharpness with robustness. This makes the insert suitable in scenarios where small to moderate interruptions in the cutting edge can occur and where process security is prioritised over extreme high-speed cutting. The PVD coating supports stable cutting at common finishing and medium-turning conditions, helping to maintain surface quality and dimensional repeatability across batches. Where corner radii and surface finish are critical, the specified 0.8 mm corner radius offers a compromise between edge strength and profile definition.
