CNMG 190616 T5125 — indexable turning insert, CVD‑coated carbide, 80° — Tungaloy

The CNMG 190616 T5125 is an ISO‑standard indexable insert for external and internal turning, optimised for cast iron applications and engineered to perform under interrupted cuts and less stable workholding conditions.

• ISO‑standard CNMG 190616 geometry
• CVD‑coated carbide grade T5125
• 80° rhombic shape with 1.6 mm radius
• Double‑sided insert with cylindrical hole

Consistent edge life for interrupted turning

The combination of a CVD‑coated surface and a wear‑resistant carbide substrate provides reliable performance where cutting conditions fluctuate. The T5125 grade is formulated as a tougher compound, which helps absorb mechanical shock during interrupted cuts in cast iron and similar materials. This resilience reduces edge chipping and extends usable life, translating into fewer insert changes and steadier production cycles. The constructive benefit is clear: improved uptime and predictable tool change intervals for medium‑ to heavy‑duty turning.

Secure clamping and proven geometry for versatility

The insert’s 80° rhombic profile and 0° relief angle deliver a robust cutting edge that balances strength and accessibility for external and internal operations. With a 1.6 mm corner radius and 6.35 mm thickness, the geometry supports stable engagement and repeatable positioning in standard ISO holders; the central cylindrical hole ensures positive clamping. Being double‑sided, the insert offers multiple effective cutting edges, improving cost efficiency per edge and simplifying inventory management for series production.

Practical selection and process advice for optimal results

Selecting the correct chipbreaker and grade is decisive: the supplied double‑sided chip control suits interrupted machining, but matching the chipformer to workpiece material and machine rigidity enhances surface finish and thermal control. The insert integrates into a system comprising a matching external holder, backing plate and securing screw; compatibility depends on form, relief, tolerance class, clamping and thickness. For mixed‑material shops, a graded approach — tougher grades for unstable conditions, harder grades for continuous high‑speed finishing — yields the best overall economy.

FAQ

What materials is this insert suited for?
The T5125 grade and its tougher carbide substrate are particularly suited to cast iron and related interrupted turning operations, providing improved resistance to chipping.

How does the CNMG 190616 geometry affect holder compatibility?
Compatibility is determined by form, relief, tolerance class, clamping method, size and thickness; the CNMG 190616 conforms to ISO dimensions for straightforward integration with standard holders.

Can the insert be indexed to use multiple edges?
Yes, the double‑sided construction allows indexing to use several cutting edges, improving cost efficiency and reducing tooling change frequency.

What benefit does the CVD coating provide?
The CVD coating increases wear resistance and improves thermal stability at the cutting edge, contributing to longer edge life under the intermittent loads typical of interrupted cuts.

Is this insert suitable for internal as well as external turning?
The rhombic 80° form and 0° relief angle make it suitable for both external and internal turning operations when paired with an appropriate holder and stable setup.
