CFGT L2020- AH869 Turning insert (ISO rhombic L2, 80°) by Tungaloy

The CFGT L2020- AH869 is an ISO-standard rhombic turning insert designed for external and internal turning of heat-resistant alloys and other demanding workpieces.

• ISO-standard rhombic insert, 80° geometry
• PVD-coated carbide AH869 for high hot hardness
• Single-sided chipbreaker, compatible with standard holders
• Central hole with 40°–60° countersink

Maximise process reliability through standardised compatibility

The insert is manufactured to the ISO turning indexable insert series, so compatibility with clamping systems is determined by insert form, clearance angle (25°), tolerance class, fastening type, size and thickness. This standardisation reduces setup complexity and minimizes the risk of incorrect seatings that can cause vibration or premature tool wear. The result is a more predictable production flow with fewer interruptions and quicker tool changes when using matched external holders or boring bars.

Extend cutting performance with a PVD-coated carbide grade

Equipped with the AH869 PVD-coated carbide grade, this insert is optimised for heat-resistant alloys and high-temperature cutting conditions. The coating improves thermal stability and wear resistance, while the substrate offers toughness under intermittent cuts. Together, these properties support a stable cutting edge, enabling higher cutting speeds and longer tool life compared with uncoated grades. For production environments this translates into higher productivity and lower tooling costs per component.

Secure clamping and efficient chip control for reliable machining

The rhombic L2 geometry with an 80° included angle and 2.38 mm plate thickness provides versatility for both external turning and internal operations where access or approach angles are restricted. The insert’s single-sided chipbreaker promotes consistent chip formation for many alloys, aiding evacuation and surface quality. Mounting is facilitated by the central cylindrical hole with a single-sided countersink (40°–60°), which ensures secure clamping and repeatable positioning in standard ISO-compatible toolholders. These design choices combine to reduce downtime and increase confidence in repeatable part quality.

FAQ

Which materials is this insert suited for?
The CFGTL2020- AH869 insert from Tungaloy is designed primarily for heat-resistant alloys and similarly demanding materials, offering high hot hardness and stable edge retention.

What does the AH869 grade provide compared with general-purpose grades?
AH869 is a PVD-coated carbide grade developed for elevated temperatures and abrasive conditions; it improves thermal resistance and wear control versus uncoated or standard coated grades.

How is the insert secured in the holder?
The insert uses a central cylindrical hole with a single-sided countersink (40°–60°) for positive clamping in compatible ISO toolholders and boring bars, ensuring repeatable seating and secure fixation.

Is the chip control suitable for through-tool coolant or interrupted cuts?
The single-sided chipbreaker on this rhombic insert promotes consistent chip formation and evacuation across a range of feeds; performance in interrupted cutting benefits from the carbide substrate’s toughness.

What are the key dimensions to check for holder compatibility?
Verify the insert geometry (80°), clearance angle 25°, insert size L2, and thickness 2.38 mm to ensure correct seating and clamp fit in the chosen holder.
