CFGT R2020- AH917 ISO turning insert — Tungaloy

The CFGT R2020- AH917 is an ISO‑standard rhombic turning insert intended for external and internal turning, offering a PVD‑coated carbide grade optimised for process security and reliable chip control.

*ISO‑standard rhombic R2 geometry
*PVD‑coated carbide grade AH917
*25° clearance for sharp cutting edge
*Cylindrical hole with single‑side countersink

Consistent cutting performance for productive turning

The rhombic R2 geometry combined with an ISO‑standard form ensures repeatable clamping and a predictable cutting line, which supports stable cycle times in serial production. The PVD‑coated carbide substrate delivers a balance between wear resistance and toughness; this means fewer insert changes and more consistent component quality. When used for external or internal turning, the one‑sided chipbreaker and the insert’s form reduce vibration and promote reliable chip formation, translating into measurable efficiency gains on the shop floor.

Durable edge and process security explained

The AH917 grade is a wear‑ and breakage‑resistant specification designed where a sharp cutting edge and high process security are demanded simultaneously. The 25° clearance angle promotes a keen edge geometry that reduces cutting forces and heat build‑up, while the PVD layer improves adhesion and abrasion resistance at elevated temperatures. For operations that require predictable tool life and a high first‑pass yield, this combination of geometry and coating supports shorter machining cycles and lower scrap rates.

Compatibility and handling for practical workshop use

Compatibility with the holder depends on the insert form, clearance angle, tolerance class, fastening and thickness; the ISO designation and the rhombic shape simplify selection for standard turning toolholders. The insert is supplied with a cylindrical locating hole and a single‑side countersink (40°–60°), enabling secure clamping with standard screws and seatings. For workshop planning, the ISO model series allows straightforward inventory management and easy replacement of worn inserts, supporting uninterrupted production and predictable tooling costs.

FAQ

What turning tasks is this insert best suited for?
The CFGT R2020- AH917 turning insert by Tungaloy is optimised for both external and internal turning where a sharp cutting edge and stable chip formation are required.

How does the AH917 grade improve tool life?
The AH917 PVD‑coated carbide offers enhanced wear resistance and edge stability, which extends tool life and maintains consistent performance under typical turning loads.

Which holders are compatible with this insert geometry?
Compatibility is determined by the ISO form R2020‑, clearance angle, tolerance class, fastening and insert thickness; the ISO‑standard rhombic shape allows use with matching ISO turning holders.

What is the purpose of the single‑side countersink in the hole?
The cylindrical hole with a single‑side countersink (40°–60°) ensures reliable clamping and correct seating, improving repeatability when mounted in standard toolholders.

Can this insert handle interrupted cuts or unstable setups?
The AH917 grade is designed for improved resistance to chipping and breakage, offering better performance in applications with moderate interruption or less rigid setups.
