CNMG120408 T515 — Indexable turning insert for turning, CVD‑coated carbide (Tungaloy)

The CNMG120408 T515 is an ISO‑standard indexable turning insert optimised for economical machining of cast iron in external and internal turning operations

• CVD‑coated carbide for cast iron machining
• 80° rhombic geometry for stable cutting
• 0.8 mm corner radius for enhanced edge strength
• Double‑sided chipbreaker with cylindrical hole for secure clamping

Improved productivity for cast‑iron turning

The T515 grade combines a CVD‑coated surface with a wear‑resistant carbide substrate to deliver economical machining of cast iron. The coating reduces flank wear at common cutting speeds, while the substrate maintains edge integrity during interrupted cuts. For workshops seeking predictable cycle times, this grade offers a balance of tool life and cutting performance that reduces rework and keeps parts within tolerance. The insert conforms to ISO dimensions, making it straightforward to source compatible toolholders and replacement plates.

Stable cutting geometry and secure clamping

Featuring an 80° rhombic geometry and a 0.8 mm radius, the insert provides secure engagement and good edge strength for heavier cuts and less rigid set‑ups. The specified 0° clearance denotes the flank relief characteristic; matching holder geometry ensures correct seating and clearance during turning. A double‑sided chipbreaker supports repeatable chip control, while the cylindrical hole facilitates stable clamping and easy indexing. These attributes together create process security, minimising vibration and promoting consistent surface finish.

Practical integration into production workflows

The ISO‑format design allows simple integration with standard external holders or boring bars, accompanied by the required shim/clamp sets and replacement screws. Selection of chipbreaker style and cutting parameters should follow the component material, stability of the set‑up and whether the cut is continuous or interrupted. Using this insert as part of a matched system reduces downtime for tool changes and inventory complexity, supporting higher overall productivity and a predictable maintenance cycle for the toolroom.

FAQ

Which materials is this insert optimised for?
The CNMG120408 T515 insert from Tungaloy is optimised for economical machining of cast iron; the T515 grade and CVD‑coating are selected to improve wear resistance with grey and nodular cast irons.

How is compatibility with a toolholder verified?
Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; check that the holder accepts CNMG‑format ISO inserts and matches the 12 mm size and 4.76 mm thickness.

Can the insert be indexed or rotated for multiple uses?
Yes — the double‑sided chipbreaker and cylindrical hole allow secure indexing; the insert can be rotated to present a fresh cutting edge, extending usable life before disposal.

What advantages does the T515 grade offer in production?
T515 provides an economical balance between wear resistance and edge stability for cast iron turning, offering consistent performance under varying cutting conditions and reducing tool change frequency.

Which operations are typical for this insert?
Typical uses include external and internal turning operations where cast iron workpieces are machined; select chipbreaker and cutting data based on workpiece stability and whether cuts are continuous or interrupted.
