TGTT L2020K AH996 — Tungaloy indexable insert for turning, PVD‑coated carbide, 60°

TGTTL2020K AH996 Tungaloy indexable insert — an ISO‑standard triangular insert designed for reliable external and internal turning in production environments

• PVD-coated AH996 carbide
• Sharp cutting edge for process security
• Triangular ISO insert, 60°
• One-sided chipbreaker, with hole

High reproducibility and wear resistance for continuous turning

The PVD‑coated AH996 carbide substrate provides a balance of wear resistance and edge toughness that supports long cutting intervals in serial turning. The coating technology increases surface hardness while preserving a sharp cutting edge, which reduces built‑up edge and improves dimensional consistency. This results in more predictable tool life and fewer unscheduled interruptions, making the insert particularly suitable for production runs where process security and uptime are priorities.

Reliable geometry and secure clamping for stable machining

The insert features an ISO L2020K designation in a triangular form with a 60° cutting angle and a 30° clearance (freespace) angle, optimised for both external and internal turning operations. The plate thickness of 2.38 mm and the cylindrical hole with a single‑side countersink (40°–60°) ensure precise seating in compliant ISO holders and bores. These dimensional characteristics support accurate repeat mounting and minimise play, which directly benefits component tolerances and surface finish quality.

Efficient chip control and material versatility in turning tasks

Equipped with a one‑sided chipbreaker, the insert directs chip flow for consistent evacuation in a wide range of turning conditions. Select the AH996 chipbreaker and grade to match the workpiece material and machining stability — the combination promotes stable chip formation and reduces machining noise. The system approach (ISO insert plus matching external holder, shim/clamping set and replacement screws) allows quick insert changes and predictable cutting behaviour, enhancing both productivity and process planning.

FAQ

What ISO designation does this insert have?
The insert carries the ISO designation L2020K, corresponding to the triangular form and dimensional class for the TGTTL2020K AH996 Tungaloy indexable insert.

Which materials and operations suit this grade?
The AH996 grade with its PVD coating is designed for turning tasks that require a sharp cutting edge and reliable wear resistance; it performs well across typical turning applications when the chipbreaker and grade are matched to the workpiece and stability.

How does the hole and countersink affect mounting?
The insert’s cylindrical hole with single‑side countersink (40°–60°) ensures stable seating in ISO‑compatible holders and supports repeatable clamping torque and alignment for consistent machining results.

What are the main benefits of the triangular 60° geometry?
A 60° triangular geometry provides multiple indexing corners and a favourable approach angle for many turning operations, offering versatility and economical use of each insert corner in serial production.

Is the TGTTL2020K compatible with standard ISO holders?
Yes; the TGTTL2020K is an ISO‑standard turning insert and its compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness — select the corresponding ISO holder and clamping set for best results.
