CFGT L2020- AH876 ISO turning insert for turning — Tungaloy

The CFGTL2020- AH876 Tungaloy insert is an ISO‑format, rhombic indexable insert designed for external and internal turning of heat‑resistant alloys and other demanding materials.

• PVD-coated carbide AH876
• For heat‑resistant alloys and tough materials
• Rhombic ISO insert, 80° included angle
• 25° clearance angle, cylindrical hole and countersink

Reliable machining of heat‑resistant alloys and tough materials

The combination of a PVD‑coated carbide grade and a geometry tailored for demanding workpieces delivers stable cutting performance when machining heat‑resistant alloys. The AH876 grade provides enhanced hot hardness and wear resistance, which reduces flank wear and maintains dimensional stability during extended cuts. For production environments where consistent surface finish and reproducibility matter, this indexable geometry supports predictable tool life and fewer insert changes, contributing to lower process interruptions and higher productivity.

Clear compatibility reduces setup uncertainty

Based on the ISO series design, the insert’s compatibility with holders is determined by form, clearance angle, tolerance class, fixation, size and thickness. The rhombic ISO outline and the specified 80° included angle enable straightforward selection of matching external holders or boring bars. The cylindrical hole with a single‑sided countersink (40°–60°) supports secure clamping and repeatable positioning, simplifying tool changeovers and reducing setup time on the shop floor. Compatibility‑driven selection helps to avoid costly trial‑and‑error in tool assembly.

Geometry and chip control for stable cutting

This insert features a single‑sided chipbreaker that is optimised for turning processes where controlled chip formation is required. The chipbreaker groove and edge preparation help to produce predictable chips across a range of feeds and depths of cut, aiding evacuation and preventing entanglement in automated machining. The moderate 25° clearance angle balances edge strength and chip flow, making the insert suitable for finishing and medium machining of tough materials while maintaining surface integrity.

Practical benefits for production and maintenance

Using an indexable insert in this specification reduces overall tooling costs by enabling economical insert replacement while retaining the same holder. The PVD coating extends tool life under elevated temperatures typical of high cutting speeds and heavy workpiece alloys, and the robust carbide substrate preserves the cutting edge during interrupted cuts. For operations focused on throughput and process stability, these features translate into fewer unplanned stoppages and more consistent part quality.

FAQ

What materials is this insert suitable for?
The CFGTL2020- AH876 insert is designed primarily for heat‑resistant alloys and other demanding materials; the AH876 grade and PVD coating improve hot hardness and wear resistance during such machining.

Which holder types are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fixation, size and thickness; use holders specified for the ISO L2020 geometry to ensure correct seating and clamping.

How does the chipbreaker affect machining performance?
The single‑sided chipbreaker on this insert promotes predictable chip formation and evacuation, which contributes to process stability and reduces risk of chip entanglement in turning operations.

What are the key dimensional features to check before fitting the insert?
Verify the 80° included angle, 25° clearance angle, the L2 size specification and the cylindrical hole with the 40°–60° countersink to ensure correct mechanical fit and clamping.

Is the coating suitable for high cutting speeds?
Yes; the PVD coating on the AH876 grade is selected to enhance thermal resistance and edge life at elevated cutting temperatures typical of faster cutting regimes.
