CNMG160612 T5115 CNMG indexable turning insert — ISO turning insert, rhombic 80°, Tungaloy

The CNMG160612 T5115 is an ISO-standard rhombic indexable insert for external and internal turning, engineered for productive machining of cast iron with a balance of abrasion resistance and cutting-edge stability.

• CVD-coated cemented carbide grade T5115
• Optimised for cast iron machining
• Rhombic CNMG shape with 80° cutting geometry
• Double-sided chipbreaker, cylindrical hole design
• Corner radius 1.2 mm for robust cutting

Consistent cutting performance through CVD-coated grade technology

The use of a CVD-coated cemented carbide substrate, specified as T5115, provides a combination of wear resistance and maintained edge integrity that supports longer intervals between indexings. This universal grade is tailored for cast iron applications and is intended to reduce flank wear under interrupted and steady cutting conditions. For production environments, the result is fewer insert changes and improved process stability, which translates into higher machine uptime and lower unit production costs without compromising surface quality.

ISO compatibility and secure clamping for repeatable results

Designed to the ISO specification, the insert’s compatibility with clamping systems depends on shape, relief, tolerance class, fastening method, size and thickness. The rhombic CNMG form with an included angle of 80° and a 0° relief presents predictable engagement with holders; the cylindrical hole ensures positive seating and simplified replacement. As an ISO-standard component, the insert is intended for use with matching external holders or boring bars, together with shims, clamp sets and replacement screws, enabling a modular system build‑up that supports repeatable set-up and reduced fixturing errors.

Application guidance: machining benefits and practical selection tips

For external and internal turning, select the double-sided insert and a matching chipbreaker according to workpiece material, machining strategy and fixture stability; the integrated chip control design supports swarf removal and consistent cutting forces. The corner radius 1.2 mm provides a compromise between edge strength and surface finish, while the 6.35 mm thickness contributes to rigidity under heavy cuts. Properly matched, this insert reduces vibration, enhances dimensional repeatability and helps maintain a consistent tool life across batches. If uncertainty remains about the optimal grade or chipbreaker for a specific setup, technical advice is available to define parameters that preserve tool life and part quality.

FAQ

What materials is this insert optimised for?
The CNMG160612 T5115 insert is optimised for cast iron machining; the T5115 grade balances abrasion resistance and edge stability for such materials.

Can the insert be used for both external and internal turning?
Yes—the ISO-format CNMG shape and cylindrical hole allow use in suitable external holders and boring bars for both external and internal turning operations.

How is the insert mounted and secured in the holder?
Compatibility is determined by form, relief, tolerance class, fastening, size and thickness; the CNMG160612 uses a cylindrical hole for secure seating and indexing in ISO-standard clamping systems.

What benefits does the 1.2 mm corner radius provide?
A corner radius of 1.2 mm increases edge robustness and helps absorb cutting forces, resulting in improved tool life and consistent surface finish under typical turning conditions.

Is the insert reversible or single-use per side?
The insert features a double-sided chipbreaker design, allowing both faces to be indexed for economical use and extended effective life of each insert.
