TGTT L2020K AH999 turning insert by Tungaloy — PVD-coated carbide, 30° relief

TGTT L2020K AH999 is an ISO-format triangular turning insert designed for external and internal turning operations, offering high process security and a sharp, durable cutting edge.

• ISO triangular insert TGTTL2020K L2020K
• PVD-coated AH999 carbide, high wear resistance
• 30° relief, 60° cutting angle for versatility
• Cylindrical hole with single-side countersink 40°–60°

Consistent tool life through a wear-resistant coating

The combination of a PVD-coated carbide grade and a robust insert geometry delivers reliable tool life and consistent performance in series production. The AH999 coating is engineered for resistance to flank wear and chipping, which reduces unplanned interruptions and keeps machining times predictable. For industrial turning applications this means fewer insert changes and more stable cycle times, supporting higher throughput with lowered process variability.

Compatibility and mounting for secure clamping

Compatibility with holders depends on insert form, relief angle, tolerance class, fastening method, size and thickness; the insert features a cylindrical hole with a single-side countersink (40°–60°) to match standard clamping systems. A correct pairing of insert and clamping kit ensures the intended cutting geometry is preserved and that the 30° relief angle is maintained under cutting loads. When assembling, check that the shim and screw dimensions correspond to the ISO holder to guarantee repeatable positioning.

Application guidance for material choice and chip control

The triangular geometry and one-sided chipbreaker suit a wide range of turning tasks; select the chipbreaker and grade according to the workpiece material and machining conditions. The insert is intended for turning operations where a sharp cutting edge and process security are required. In practice, this insert performs well when used with stable setups and appropriate cutting parameters, and it is compatible with standard ISO tool systems when matched correctly.
