CNMA190616 T5125 — ISO turning insert CNMA 190616 T5125 for turning, Tungaloy

A CNMA190616 T5125 indexable insert engineered for external and internal turning, especially where interrupted cuts or unstable set-ups demand a tougher, CVD-coated carbide grade.

• CVD-coated carbide grade T5125
• Optimised for interrupted cuts
• 80° rhombic shape with 1.6 mm radius

Precision and reliability for demanding turning operations

The insert’s CVD-coated surface and T5125 grade deliver a balance of toughness and wear resistance that benefits components produced from brittle or variable materials. The substrate of carbide provides the hardness needed for sustained cutting, while the coating reduces flank wear and increases edge life. In practice, this results in fewer tool changes and steadier component quality when machining cast components or mixed-material batches. The geometry helps convert vibrations into controlled chip formation, so surface finish and process repeatability improve under interrupted cutting cycles.

Seamless integration into ISO tool systems for efficient setup

Designed to ISO dimensions, the plate fits holders determined by form, clearance and dimensional tolerances, reducing set-up time and inventory complexity. The 80° rhombic form with a 0° clearance angle and the standard size of 19 mm × 6.35 mm ensure compatibility with common external holders and boring bars. A cylindrical hole secures the insert reliably in the pocket and simplifies indexation. The net effect for production: faster changeovers, predictable clamping accuracy and lower risk of incorrect mounting.

Robust choice where interrupted cuts or instability occur

The tougher CVD-coated grade is specified for machining cast iron under interrupted cutting or less stable conditions; this means the insert resists chipping and maintains a usable edge longer than standard grades. With a 1.6 mm corner radius, the cutting edge offers enhanced strength, which reduces the likelihood of edge fracture and supports higher feed rates when permissible. The lack of a chipbreaker on this plate calls for compatible cutting strategies or dedicated chip management, but it also leaves flexibility for customised chip control via cutting parameters or holder-integrated features.

FAQ

What materials is this insert suitable for?
The CNMA190616 T5125 Tungaloy turning insert (SKU TUN6850180) is formulated for machining cast iron and similar materials where interrupted cuts or unstable conditions occur; its CVD-coated carbide grade increases resistance to chipping.

Which holder characteristics ensure compatibility?
Compatibility requires a holder matching the CNMA form, the 19 mm size and 6.35 mm thickness, the rhombic profile and the 0° clearance; correct fastening, tolerance class and pocket geometry ensure secure clamping of the insert.

What does the T5125 designation indicate?
T5125 denotes a CVD-coated carbide grade optimised for toughness; the coating improves wear resistance while the substrate supports impact strength, making it suitable for interrupted machining.

Is there a chipbreaker on this insert?
This plate is supplied without a chipbreaker; machining strategies should account for chip control via cutting parameters or use of toolholders that assist chip evacuation.

How does the 1.6 mm corner radius affect performance?
A 1.6 mm corner radius increases edge robustness, reduces risk of fracture under interrupted loads and can permit higher feed rates, while slightly influencing achievable fine-profile machining radius.
