TNMG270608 AH120 Tungaloy turning insert — PVD-coated carbide, 60° triangle

A TNMG270608 AH120 indexable insert for ISO-standard turning, designed for stable, high-reliability external and internal turning operations

• ISO TNMG triangle insert, 60° geometry
• PVD-coated AH120 carbide for wear resistance
• Double-sided chipbreaker for consistent chips
• 0° clearance angle for sharp cutting edge

Enhanced machining stability with a wear-resistant grade

The combination of a PVD-coated surface and the AH120 carbide composition delivers a balance of wear resistance and fracture toughness that supports steady cutting conditions. Specified as an ISO-style indexable insert, this triangular tool provides a consistent contact geometry that helps to maintain a sharp cutting edge over extended runs. The result is measurable process stability: fewer unscheduled tool changes, more predictable component quality and improved overall efficiency in turning applications where repeatability matters.

Versatile use and matching to holder systems

Designed for both external and internal turning, the insert is part of a standardised ISO system and therefore integrates with a wide range of holders when form, clearance angle, tolerance class, fastening method, size and thickness align. The insert’s triangular shape and double-sided chipbreaker allow rotation for fresh cutting edges, optimising tool utilisation. Selection of the correct chipbreaker and grade should be based on the workpiece material and machining conditions to achieve the intended surface finish and chip control.

Geometry and dimensions that support robust setups

Key dimensional features contribute directly to handling and performance: the 60° geometry and R0.8 mm corner radius give a reliable compromise between edge strength and the potential for fine finishes. With a thickness of 6.35 mm and an inscribed circle of 27 mm, the insert offers mechanical stability in clamping and resistance to deflection under cutting forces. The design includes a cylindrical hole, enabling secure fastening to compatible holders and straightforward indexability for rapid insert changes during production.

Practical system considerations and productivity gains

As part of a complete turning system, the insert works together with an appropriate outer holder or boring bar, underlay/shim and fastening screws to ensure repeatable clamping and positional accuracy. The PVD surface treatment supports consistent tool life, which lowers tooling consumption and contributes to reduced downtime. For operations requiring a sharp edge and high process reliability, this indexable insert provides a pragmatic route to improved throughput while simplifying inventory: a small range of well-chosen grades and chipbreakers can cover many everyday turning tasks.

FAQ

What machining tasks is this insert suited for?
The AH120 grade is formulated for turning tasks that demand a wear- and fracture-resistant cutting edge; it is intended for stable external and internal turning where process security is required.

Is the TNMG270608 compatible with my ISO holders?
Compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness; the TNMG270608 fits standard ISO indexable holder concepts when those parameters correspond.

How does the AH120 PVD coating affect performance?
The PVD-coated AH120 surface reduces abrasive wear and improves edge integrity, extending effective cutting life and helping to maintain consistent component quality.

What are the key dimensions to check before ordering?
Important dimensions include the 27 mm inscribed circle, 6.35 mm thickness and R0.8 mm corner radius; verify the 60° geometry and the presence of the cylindrical hole for correct mounting.

Can the insert be rotated for multiple cutting edges?
Yes — the triangular format with a double-sided chipbreaker enables indexing to fresh edges, enhancing utilisation and reducing tooling change frequency.
