CFGT R2020- AH914 indexable turning insert by Tungaloy — PVD-coated carbide, rhombic R2

The CFGT R2020- AH914 is an ISO‑standardised, rhombic turning insert engineered for general external and internal turning where a sharp cutting edge and reliable process security are required.

ISO‑standard indexable insert PVD-coated carbide AH914 grade Rhombic R2 shape with 80° cutting edge One-sided chipbreaker for controlled chips

Consistent productivity through optimised cutting performance

The combination of a PVD-coated surface and a wear-resistant carbide substrate in this grade delivers a measurable improvement in edge life and process stability. The coating reduces adhesion and flank wear under a range of cutting conditions, which translates into longer intervals between indexings and fewer unscheduled tool changes. For production environments prioritising throughput, this insert reduces downtime and helps maintain component tolerances across batches.

Clear compatibility and secure mounting for rapid setup

Designed as an ISO‑indexable plate, the geometry and mounting features ensure predictable fitment with compatible holders. The rhombic R2 form and central fastening hole with a cylindrical bore and single-side countersink (40°–60°) provide consistent seating and clamping torque, lowering the risk of misalignment. Knowing the relief angle of 25° and the nominal cutting‑edge orientation (80°) simplifies holder selection and cutting parameter calculation, easing tool changeover and setup for mixed production runs.

Application-specific benefits from material and chip control

The one-sided chipbreaker and the AH914 grade balance edge sharpness with fracture resistance, making the insert suitable for varied turning tasks where both finish and process security matter. In practice, this means better chip control on interrupted cuts and improved surface quality on continuous cuts, especially when combined with a matched holder and correct feeds. The ISO designation and standardised system concept also support inventory rationalisation and predictable reorder behaviour.

FAQ

What materials is this insert suitable for?
The AH914 PVD‑coated carbide insert is formulated for a wide range of steels and general turning tasks; select the matching chipbreaker and machining parameters for best results.

How does the rhombic R2 shape affect holder selection?
Rhombic R2 geometry requires a compatible indexable holder that accepts the R2 size and provides correct seating for the ISO hole and clamping style, ensuring secure mounting and repeatable positioning.

Can the insert handle interrupted cuts?
Yes, the one-sided chipbreaker and the wear‑resistant AH914 grade offer improved chip control and fracture resistance for interrupted turning when clamped correctly.

How is the insert identified for reordering?
Use the designation CFGTR2020- AH914 or the manufacturer SKU TUN6801676 to ensure the exact PVD‑coated carbide grade and geometry are supplied.

What relief and cutting angles should be considered during setup?
Plan for a relief angle of 25° and a cutting‑edge orientation of 80°; these values help determine the proper holder geometry and cutting parameters.
