TGTT L2020K AH997 TGTTL2020K — Turning insert (ISO) by Tungaloy

A TGTTL2020K AH997 ISO triangular turning insert designed for ISO-standard external and internal turning, offering a sharp cutting edge and high process security.

• PVD-coated carbide grade AH997
• Wear- and fracture-resistant cutting grade
• ISO-standard triangular insert L2 with 30° clearance
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for efficient turning

The combination of a PVD-coated surface and a carbide substrate in grade AH997 delivers a balance of wear resistance and edge stability that reduces unplanned tool changes. The insert’s geometry is configured for predictable cutting forces and a sharp cutting edge, which supports stable chip formation and helps maintain component tolerances over longer production runs. This results in improved process throughput and a lower cost per part when compared with tools that require more frequent regrinding or replacement.

Precise ISO compatibility that simplifies setup

Designed as part of the ISO turning insert family, the geometry and tolerance class ensure compatibility with standard clamping systems when the holder is selected according to form, free clearance angle, fastening type, size and thickness. The triangular L2 format and a plate thickness of 2.38 mm combine with a 30° clearance to provide secure seating in many common external holder styles. The insert’s cylindrical hole with a one-sided countersink (40°–60°) yields repeatable clamping and simplifies torque setting for the clamping screw, reducing setup time and the incidence of mounting errors.

Selectable chip control and process security for diverse turning tasks

This cutting grade is specified as wear- and break-resistant, and the insert is supplied with a single-sided chipbreaker, enabling adaptation to varied cutting conditions. For operations that demand a sharp cutting edge alongside dependable process security, the grade performs reliably; the chipbreaker geometry should be matched to the workpiece material and machining stability to achieve optimal chip evacuation and surface finish. The insert’s characteristics support consistent cycle times and help to avoid unexpected interruptions during continuous production.

Practical system advantages for the workshop

The insert is intended to be used within the standard system build of an ISO turning setup: ISO insert, suitable outer holder or boring bar, shim/locking set and replacement screws. This system approach ensures spare parts and replacements are easy to source and fit, minimising downtime. The triangular shape and ISO coding also make inventory management straightforward, while the robust AH997 coating technology contributes to longer in-service life and more predictable tool change intervals — a clear advantage for high-volume turning operations seeking to increase machine utilisation.

FAQ

What holders are compatible with this ISO triangular insert?
Compatibility depends on the holder’s form, free clearance angle, tolerance class, fastening method, size and thickness; the TGTTL2020K AH997 insert fits holders designed for ISO triangular L2 inserts.

Is the TGTTL2020K AH997 suitable for finishing and roughing?
The AH997 grade is designed for wear resistance and edge stability; the TGTTL2020K can be used for both finishing and certain roughing tasks, with chipbreaker choice and cutting parameters adjusted to the operation.

How does the hole and countersink affect clamping?
The cylindrical hole with a one-sided countersink (40°–60°) on the TGTTL2020K provides repeatable seating and secure clamping, which improves mounting consistency and reduces the risk of movement under load.

What are the main advantages of the PVD coating on this insert?
The PVD-coated surface on the AH997 grade increases wear resistance and helps maintain a sharp cutting edge, contributing to predictable tool life and process reliability for turning operations.

Which components complete the system with this insert?
A compatible outer holder or boring bar, the correct shim/locking set and replacement screws form the recommended system for secure and accurate use of the TGTTL2020K insert.
