CNMG 120416 T5115 Turning Insert — Tungaloy (CVD-coated carbide, 80°)

A CNMG120416 T5115 indexable insert for external and internal turning, optimised for cast iron machining with a stable cutting edge and universal chip control.

• ISO CNMG 120416 rhombic 80°
• CVD-coated carbide grade T5115
• Double-sided chipbreaker, cylindrical hole
• 1.6 mm corner radius, 4.76 mm thickness

High-performance grade for consistent edge life

The CVD-coated T5115 carbide grade offers a well-balanced combination of wear resistance and edge stability, making it suitable for a wide range of cast iron turning tasks. The chemical vapour deposition (CVD) layer increases resistance to abrasive wear at elevated cutting temperatures, which extends the effective service life of the insert while maintaining dimensional accuracy. This results in fewer tool changes and more predictable cycle times on batch and single-piece production alike, supporting a more efficient machining process.

ISO compatibility simplifies toolholder selection

The insert follows the ISO CNMG profile and is supplied in the standard CNMG120416 format, which ensures compatibility with common external holders and boring bars when matched by form, clearance angle, tolerance class, fixing method, size and thickness. The rhombic 80° shape and 0° clearance angle demand the correct seating and clamping; the insert’s cylindrical locating hole and double-sided design allow economical use of both cutting faces. This standardisation reduces setup complexity and helps to maintain repeatable clamping accuracy in everyday shop-floor conditions.

Practical application advice for turning cast iron

Designed primarily for turning operations on cast iron, the insert performs well in both external and internal turning when paired with an appropriate chipbreaker and toolholder rigidity. The 1.6 mm corner radius supports robust edge strength for interrupted cuts and general-purpose profiling, while the 4.76 mm plate thickness contributes to stability under moderate cutting forces. Select the double-sided chipbreaker and the T5115 grade to match the workpiece condition and machine stability; a stable setup and correct feed/speed settings will deliver the best surface finish and tool life.
