CFGTL2020- AH870 Tungaloy — ISO turning insert, PVD-coated carbide, 80°

The CFGTL2020- AH870 Tungaloy insert is an ISO-form indexable turning insert engineered for demanding turning of heat-resistant alloys and other challenging materials.

• PVD-coated carbide grade AH870
• Rhombic L2 form with 80° cutting angle
• 25° clearance angle for versatile turning
• Cylindrical hole with single-side countersink
• One-sided chipbreaker for controlled swarf

Robust grade for high-temperature materials and consistent cutting performance

The insert uses a PVD-coated carbide substrate in the AH870 grade, developed for machining heat-resistant alloys and other demanding workpiece materials. The coating enhances hot hardness and edge stability, which directly reduces flank wear under thermal stress and extends cutting life. Thanks to this combination, the component sustains higher cutting temperatures while maintaining a sharp edge, providing a more predictable tool life and fewer unscheduled tool changes for improved shop-floor efficiency.

Secure clamping and ISO conformity for interchangeability

Designed as an ISO-compliant turning insert, compatibility with toolholders is governed by form, clearance angle, tolerance class, fixation, size and thickness. The rhombic L2 form with an 80° cutting angle and a 25° clearance offers versatile positioning for external and internal turning. A cylindrical hole with a single-sided countersink (40°–60°) and a plate thickness of 2.38 mm deliver reliable mechanical support and repeatable seating in the clamping assembly, reducing the risk of micro-movements that can impair surface finish and dimensional accuracy.

Improved chip control and application-oriented system design

The single-sided chipbreaker geometry is tuned for consistent swarf formation when working on less stable set-ups or when machining near heat-resistant alloys; this leads to safer chip evacuation and reduced risk of entanglement. As part of an ISO turning system, the full setup comprises the indexable insert, a matching external holder or boring bar, an underlay/clamp set and replacement screws, allowing straightforward integration into existing tool systems. Choosing the correct chipbreaker and insert grade according to workpiece material and machining stability ensures better productivity and lower overall process costs.

Guidance for selection and process reliability

For best outcomes, match the insert’s AH870 grade and chipbreaker to the workpiece material and machine rigidity; the grade excels where high warm hardness and sustained edge integrity are required. The insert’s rhombic geometry supports a range of turning operations while the PVD coating enhances wear resistance. Where process security and repeatable surface quality matter, this insert offers a balance of durability, thermal stability and ease of replacement within standard ISO holder systems.
