CNMG160616 T5125 — ISO CNMG 80° rhombic indexable insert for turning by Tungaloy

The CNMG160616 T5125 is an ISO rhombic indexable insert for external and internal turning, optimised for machining cast iron where interrupted cuts or less stable setups are expected.

• CVD‑coated carbide grade T5125
• Suited for cast iron and interrupted cuts
• Rhombic CNMG 80° geometry
• Double‑sided chipbreaker, with cylindrical hole

Predictable chip control for repeatable part quality

The combination of a CVD‑coated carbide substrate and a double‑sided chipbreaker delivers consistent chip formation even in variable cutting conditions. The coated layer increases wear resistance while the chipbreaker geometry reduces the risk of long, tangled chips; this translates into fewer stoppages and a more predictable surface finish. For shops processing cast iron, the T5125 grade provides a tougher edge that tolerates vibration and shock, so cycle times remain stable and rework rates fall.

Robust edge stability when conditions are challenging

Designed for interrupted cuts and less rigid setups, the insert’s rhombic CNMG shape with an 80° cutting angle provides a secure cutting edge and good side‑cutting strength. The tougher carbide composition resists chipping at the corner, extending effective tool life under shock loads. Explaining the term: CVD‑coated means a chemical vapour deposition layer is applied to the cemented carbide to enhance surface hardness and oxidation protection, which benefits throughput by delaying flank wear and maintaining dimensional accuracy over longer bore or external turning runs.

Efficient handling and simple tool setup for production use

Compatibility with a suitable holder is determined by form, relief angle, tolerance class, fastening, size and thickness; the insert’s 6.35 mm thickness, 16 mm inscribed circle and 1.6 mm corner radius make it straightforward to match with standard CNMG toolholders. The profile — rhombic CNMG with a cylindrical hole — permits reliable clamping and repeatable indexing, reducing setup time during tool changeovers. Fewer handling steps and predictable indexing help maintain productive machine utilisation and reduce operator error.

FAQ

What materials is this insert designed for?
The CNMG160616 T5125 insert is optimised for machining cast iron; the T5125 CVD‑coated carbide grade offers a tougher edge for interrupted cuts and mixed stability conditions.

How does the coating benefit performance?
The CVD coating on this Tungaloy grade increases surface hardness and oxidation resistance, delaying flank wear and helping the insert maintain dimensional accuracy over extended runs.

Which holder geometry is required for the insert?
Compatibility depends on holder form, clearance (0° relief here), tolerance class, fastening and size; the CNMG 16 inscribed circle and 6.35 mm thickness match standard CNMG toolholders when the holder is specified for ISO CNMG inserts.

Can the insert be indexed to present a fresh edge?
Yes, the insert is double‑sided with multiple cutting edges; indexing to a new edge restores cutting performance without discarding the carbide body.

What does the 80° designation mean for cutting?
The 80° geometry indicates the major cutting angle of the rhombic insert, offering improved side strength and suitability for both external turning and light side‑cutting operations.
