CNMG120416 T515 Turning Insert (ISO CNMG 120416) — CVD-coated carbide, 1.6 mm radius | Tungaloy

The CNMG120416 T515 is an ISO rhombic turning insert engineered for economical and reliable machining of cast iron in both external and internal turning operations

• CVD-coated carbide grade T515
• ISO CNMG 120416 rhombic insert
• 80° approach angle, 1.6 mm nose radius
• Double-sided chipbreaker, cylindrical mounting hole

Productive machining with optimised chip control

The combination of a CVD-coated carbide substrate and the T515 grade results in consistently stable cutting performance when machining cast iron. The coating enhances wear resistance and reduces built-up edge, which extends tool life and maintains a predictable cutting-to-wear ratio. As a consequence, cycle times are minimised and tool-change intervals are spaced further apart, delivering measurable improvements in manufacturing efficiency and component consistency.

Clear mounting and holder compatibility for reliable assembly

The insert's rhombic form, cylindrical hole and defined geometrical parameters determine compatibility with indexable toolholders. Matching the insert to an appropriate holder requires checking the insert form, clearance angle (0°), tolerance class, clamping design, nominal size and plate thickness. The presence of a double-sided chipbreaker allows reversed indexing for economical use of cutting edges, while the cylindrical hole ensures secure seating and repeatable positioning during assembly and re-indexing.

Practical application guidance and system context

Designed within the ISO indexable turning insert system, the plate works best with a matched external holder or boring bar, shim/clamp set and the correct clamping screws. For interrupted cuts or less stable set-ups, selecting the appropriate chipbreaker variant and ensuring robust clamping will preserve edge integrity and surface finish. The insert supports both roughing and finishing passes when used with correct speeds and feeds for cast iron and is suitable where predictable process behaviour and ease of indexability are priorities.

FAQ

What materials is the insert suited for?
The CNMG120416 T515 insert is optimised for cast iron machining; the T515 grade and CVD-coated carbide composition provide stable chip control when turning cast iron.

How many cutting edges are available on this insert?
Thanks to the double-sided geometry, the insert offers multiple usable cutting edges through indexing, improving economy per insert.

Which holders are compatible with this insert?
Compatibility is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness; holders designed for ISO CNMG 120416 inserts are appropriate.

How does the 1.6 mm nose radius affect the process?
The 1.6 mm radius balances edge strength and surface finish capability, making it suitable for medium-duty finishing and semi-finishing operations.

Is this insert field-replaceable and easy to index?
Yes. The rhombic form with a cylindrical hole and standard ISO dimensions enables straightforward indexing and replacement in compatible toolholders.
