CFGT R2020- AH915 turning insert by Tungaloy

CFGT R2020- AH915 is an ISO‑standard rhombic turning insert designed for reliable external and internal turning in production environments

• PVD-coated carbide AH915 for wear resistance
• ISO‑standard rhombic insert R2 with 25° clearance
• Cylindrical hole with one-sided countersink 40°–60°
• Single-sided chipbreaker for stable chip control

High wear resistance for sustained productivity

The PVD-coated AH915 cutting grade combines a hard carbide substrate with a thin, wear‑resistant coating to extend edge life under demanding conditions. This results in fewer tool changes and longer uninterrupted runtime, supporting higher machine utilisation and predictable batch throughput. Because the grade is designed to resist both abrasion and chipping, the insert maintains a sharp cutting edge over longer cycles, which in turn preserves surface finish and reduces rework.

Geometry and clamping for process security

A rhombic profile in size R2 with an included angle of 80° and a 25° clearance angle gives a balanced geometry that is suitable for general turning operations while enabling secure seating in ISO holders. The cylindrical hole with a one‑sided countersink (40°–60°) ensures positive fixation and stable torque transfer to the insert, reducing the risk of movement under cutting loads. The single‑sided chipbreaker promotes controlled chip formation and evacuation, lowering the chance of built‑up edge and improving repeatability across similar workpieces.

Designed for straightforward integration into tool systems

As an ISO‑normed component, the insert integrates with standard clamping systems comprising a matching outer holder or boring bar, shim/clamping set and replacement screws. Compatibility is determined by shape, clearance, tolerance class, attachment method, size and thickness, so matching the insert to the correct holder is essential for optimum performance. The modular system approach simplifies stock management and makes it easier to scale operations; where application specifics are uncertain, technical consultants can advise on the ideal combination of insert, holder and cutting data.

FAQ

What turning tasks is this insert intended for?
The CFGTR2020- AH915 Tungaloy turning insert is intended for general external and internal turning operations where a wear‑resistant, fracture‑tough grade and ISO‑compatible geometry are required.

How does the AH915 coating improve tool life?
The PVD coating on the AH915 grade increases wear resistance and reduces adhesion at the cutting edge, so the insert maintains a sharp edge longer and delivers more consistent component quality.

Why is the countersunk cylindrical hole important?
A cylindrical hole with a one‑sided countersink (40°–60°) secures the insert in the seat and ensures reliable torque transfer, which improves repeatable clamping and reduces the risk of insert movement under load.

Which holders are compatible with this insert?
Compatibility depends on holder shape, clearance angle, tolerance class, attachment method, size and thickness. Use an ISO‑compatible rhombic holder sized for R2 inserts and the R2020‑ family.

What role does the chipbreaker play for machining?
The single‑sided chipbreaker on this rhombic insert promotes controlled chip formation and evacuation, improving process security and reducing the likelihood of chip‑related interruptions.
