CFGT L2020- AH872 indexable insert for turning – Tungaloy

CFGT L2020- AH872 is an ISO-standard rhombic turning indexable insert optimised for external and internal turning of demanding materials.

• PVD-coated AH872 grade
• Designed for heat-resistant alloys
• Rhombic L2 form, 80° included angle
• 25° rake; cylindrical hole + countersink

Consistent edge life for high-temperature materials

The combination of a PVD coating and a wear-resistant carbide substrate delivers extended tool life under thermal stress. The AH872 grade is engineered for elevated hot hardness, which means the cutting edge retains geometry at high cutting temperatures and reduces flank wear. For production environments handling heat-resistant alloys, this stability translates into fewer indexings, longer uninterrupted cycles and a predictable component quality, thereby improving process efficiency and reducing scrap rates.

Straightforward integration with ISO holders and secure clamping

ISO standardisation simplifies tool planning: the rhombic L2 form and the specified geometry allow direct pairing with compatible turning holders. The insert’s cylindrical hole with single-sided countersink (40°–60°) ensures secure fastening and consistent seating; the 25° rake angle supports positive cutting engagement while the 80° included angle offers robustness at the corner, balancing strength and accessibility. This predictable fitment reduces set‑up time and minimises indexing errors during tool changes, supporting a reliable production flow.

Controlled chips and improved surface finishes

A one-sided chipbreaker is integrated to promote efficient chip formation and evacuation when machining alloys prone to long, stringy chips. Effective chip control lowers the risk of re-cutting and tool damage, while also helping to maintain a consistent cutting zone temperature. The result is better surface integrity on workpieces and fewer interruptions for chip management. In semi‑automated or automated turning cells, this means fewer interventions and steadier cycle times.

Economic operation through reduced downtime and predictable performance

Using standardised, indexed inserts with a robust coating strategy reduces overall tooling costs by extending usable edge life and simplifying inventory. Replacing only the insert rather than the entire tool saves maintenance time and lowers consumable consumption. The described geometry and grade are suited for repetitive, high‑temperature turning operations, helping to maintain throughput and achieve consistent part tolerances across batches. For procurement, stocking a proven ISO family simplifies reordering and keeps production resilient.

FAQ

Which materials are suitable for this insert?
This indexable insert is specified for demanding and heat-resistant alloys; the PVD-coated AH872 grade is designed to retain hardness at elevated temperatures and is thus well suited to such workpiece materials.

How does the insert secure to the holder?
The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for stable clamping in ISO-compatible holders, ensuring consistent seating and repeatable positioning.

What advantages does the AH872 coating offer?
The AH872 PVD coating increases thermal resistance and maintains a stable cutting edge under high temperatures, which helps to extend edge life and reduce unexpected tool wear.

Is the chipbreaker suitable for automated machining?
Yes; the integrated one-sided chipbreaker promotes controlled chip formation and evacuation, reducing the need for manual intervention in automated or semi‑automated turning cells.

Which size and geometry should be matched to the holder?
Match the rhombic L2 form, 80° included angle and the ISO code L2020- to the corresponding holder specification to ensure correct compatibility and optimal performance.
