CNMG 120404 T515 ISO turning indexable insert, 80° rhombic – Tungaloy

A CNMG120404 T515 indexable insert engineered for economical external and internal turning, optimised for cast iron applications within ISO-standard tool systems.

• CVD-coated cemented carbide grade T515
• Optimised for economical cast iron machining
• Rhombic 80° insert, corner radius 0.4 mm
• Double-sided chipbreaker, cylindrical hole

Robust grade and coating for longer tool life

The combination of CVD-coated cemented carbide and the T515 grade is designed to extend tool life under typical cast iron cutting conditions. The coating reduces abrasive wear and provides thermal protection, which allows for higher cutting speeds in many operations. This results in lower tool consumption and fewer insert changes, contributing to improved machine uptime and predictable operating costs without compromising component quality.

Improved chip control and consistent surface finish

A tailored double-sided chipbreaker ensures controlled chip formation during both continuous and interrupted cuts, reducing the risk of built-up edge and surface irregularities. Better chip control leads to fewer secondary operations and less downtime for cleaning and chip management. The optimised chip flow also supports consistent surface quality, reducing process variability on serial production runs.

Secure clamping and compatibility with ISO tool systems

The insert’s 80° rhombic geometry delivers a versatile cutting edge for general turning tasks while the cylindrical hole provides positive seating and repeatable orientation in compatible holders. Compatibility is determined by form, clearance angle, tolerance class, mounting, size and thickness; this insert’s 0° clearance angle, 12 mm size and 4.76 mm thickness suit many ISO-standard external holders and boring bars. Secure clamping reduces vibration and contributes to reliable dimensional accuracy.

Application guidance for reliable machining performance

Selecting the correct chipbreaker and the T515 grade should be based on part stability, cut interruption, and desired cutting speed. For heavy interrupted cuts, prefer more robust holder arrangements and lower uncut chip thickness; for high-productivity finishes, the coating allows increased cutting speeds with maintained edge stability. The insert is particularly suited for cast iron turning where economic performance and stable chip formation are priorities.

FAQ

What workpiece materials is this insert best suited for? The CNMG120404 T515 insert is optimised for cast iron machining; the T515 grade and CVD coating provide wear resistance and stable chip formation for such materials.

How does the chipbreaker affect machining? The double-sided chipbreaker on this insert promotes controlled chip flow and reduces the risk of built-up edge, improving surface quality and process stability in turning operations.

Is the insert compatible with standard ISO holders? Compatibility depends on form, clearance angle, tolerance class, mounting and size; the CNMG120404 format with its cylindrical hole and 80° geometry fits common ISO-standard external holders and boring bars when matched correctly.

Can the insert be used for interrupted cuts? Yes; the T515 grade and robust geometry are suitable for interrupted cuts, although clamping rigidity and correct chipbreaker selection should be ensured to maintain tool life.

What are the key dimensional values to check when replacing an insert? Check the plate size (12 mm), thickness (4.76 mm), corner radius (0.4 mm) and the 80° geometry to ensure correct seating and cutting behaviour.
