CNMG 120416 T515 CNMG turning insert for cast‑iron — Tungaloy

A CNMG120416 T515 indexable insert designed for efficient external and internal turning of cast iron, compatible with ISO CNMG holders.

• CVD-coated carbide grade T515
• Optimised for cast iron machining
• Rhombic CNMG shape, 80° lead angle
• Double-sided chipbreaker, 1.6 mm radius

High productivity through tailored coating and substrate

The combination of a CVD-coated surface and a carbide substrate delivers reproducible performance when machining cast materials. The T515 grade is formulated for economical processing of cast iron, offering secure cut control under interrupted cuts and varying rigidity conditions. This results in longer effective tool life and fewer indexings, reducing non‑cutting time and improving overall throughput. The technical design supports consistent chip formation and wear behaviour, making it a reliable choice for production environments.

Geometry engineered for rigidity and precision

The rhombic CNMG format with an 80° lead angle and a 0° clearance provides a stiff cutting geometry that helps maintain dimensional accuracy on external and internal turning operations. A corner radius of 1.6 mm increases edge strength where interrupted cuts or variable stability are encountered, while the 4.76 mm thickness ensures secure seating in the pocket. The presence of a cylindrical hole facilitates positive clamping and repeatable positioning in ISO‑standard holders, which supports stable cutting conditions and consistent surface finish.

Economic advantage from insert design and chip control

A double‑sided chipbreaker reduces the need for frequent tool changes and contributes to cost efficiency over multiple indexings. The insert’s T515 coating promotes controllable chip evacuation when paired with the correct holder and cutting parameters, minimising built‑up edge and protecting the cutting edge from premature wear. For shops seeking predictable costs per component, this insert offers a balance of tool life and cutting speed that often translates into lower machining costs per part compared with uncoated grades.

Integration into ISO tool systems and recommended usage

The product is an ISO‑standard turning indexable insert intended for use with appropriate CNMG external holders or boring bars, together with the matching shim and clamp set. Typical system components include the insert, a compatible holder, underlay or clamp set and replacement screws. Selection of the correct chipbreaker and grade should be aligned to workpiece stability, the presence of interrupted cuts and the desired cutting speed to fully exploit the T515 advantages in cast‑iron turning.

FAQ

What materials is this insert optimised for? The CNMG120416 T515 is optimised for machining cast iron, with the T515 CVD coating and carbide substrate designed to control chips and wear during cast‑iron turning.

Which holder form is required for proper seating? The insert conforms to the ISO CNMG form and requires a matching CNMG external holder or boring bar that accepts the rhombic indexable insert with a cylindrical hole.

How does the 1.6 mm corner radius affect machining? A 1.6 mm corner radius increases edge strength and helps resist notch wear and chipping during interrupted cuts, improving process stability and dimensional consistency.

Is the insert suitable for interrupted cuts? Yes; the T515 grade and the reinforced geometry make the insert well suited to interrupted cutting conditions commonly encountered in cast‑iron operations.

What should be checked when selecting this insert for an application? Confirm the holder compatibility with the ISO CNMG form, evaluate workpiece stability, and choose the chipbreaker and cutting parameters that match the desired surface finish and productivity; the CNMG120416 T515 is especially effective where reliable chip control and cost efficiency are priorities.
