TGTT L2020K AH998 – Tungaloy ISO turning insert, 60° triangular

The TGTT L2020K AH998 is an ISO turning insert from Tungaloy, designed for external and internal turning where a sharp cutting edge and high process reliability are required.

• PVD-coated carbide AH998 for process security
• ISO L2020K triangular 60° insert
• 30° clearance and 2.38 mm thickness
• Cylindrical hole with 40°–60° countersink

Consistent machining through PVD-coated carbide for longer tool life

The PVD‑coated carbide grade AH998 provides a wear‑ and fracture‑resistant cutting edge that supports stable machining over extended cycles. The coating reduces flank wear and helps preserve the edge geometry under intermittent loads; this results in fewer insert changes and less unplanned downtime. For workshop managers and process engineers, the clear outcome is improved uptime and predictable tool consumption, enabling simpler planning of inserts and replacement parts.

Straightforward integration with ISO holders and clamping systems

The insert conforms to the ISO designation L2020K, so compatibility with holders is determined by the insert’s form, 30° clearance, tolerance class, fastening method, size and thickness. Integration requires a matching external holder or boring bar, plus the appropriate backing plate or clamping set and replacement screw. For production lines the standardised geometry simplifies inventory and reduces the number of specialised holders needed, supporting faster tool changes and consistent set‑up reproducibility.

Reliable performance where a sharp edge and process security are essential

This grade is intended for turning operations that demand a sharp cutting edge together with process stability. The triangular, 60° geometry concentrates the cutting forces at defined cutting corners, while the single‑sided chipbreaker assists chip control for many turning tasks. Such a configuration is particularly effective when cyclic loads or minor interruptions occur; the combination of geometry and AH998 composition reduces the risk of unexpected edge chipping and helps maintain surface quality with fewer interventions.

Stable seating and economical use thanks to precise geometry

With a plate thickness of 2.38 mm and a triangular 60° form, the insert offers firm seat contact and reliable clamping in standard ISO seats. The cylindrical hole with a 40°–60° countersink secures repeatable positioning and torque transmission, which is important for maintaining concentricity and avoiding insert movement during heavy cuts. The result is reproducible part quality and a positive effect on overall tool economy through fewer reworks and extended service life of the cutting edge.

FAQ

What are the principal benefits of the TGTTL2020K AH998 insert?
The TGTTL2020K AH998 insert from Tungaloy is a PVD‑coated carbide grade offering wear‑ and fracture‑resistant performance and a sharp cutting edge, delivering enhanced process reliability in turning operations.

Which factors determine whether the insert fits a specific holder?
Compatibility is governed by form, clearance angle (30°), tolerance class, fastening method, overall size and plate thickness (2.38 mm); matching the ISO L2020K designation ensures the correct seat and clamping arrangement.

For which turning operations is this insert suited?
The insert is intended for external and internal turning where a sharp edge and process stability are required; the single‑sided chipbreaker supports controlled chip formation in typical turning cycles.

How does the hole and countersink design affect performance?
The cylindrical hole with a 40°–60° single‑side countersink provides repeatable positioning and secure clamping, reducing the risk of insert movement and contributing to consistent part geometry.

What does the AH998 grade mean in practice?
AH998 denotes a PVD‑coated carbide composition designed to resist wear and chipping, helping to maintain edge integrity under varying cutting conditions and extending the usable life of each insert.
