CNMG120416 T505 ISO turning insert for cast‑iron machining by Tungaloy

CNMG120416 T505 is an ISO‑standard rhombic indexable insert engineered for external and internal turning of cast iron, supplied in a CVD‑coated cemented carbide grade.

• CVD-coated cemented carbide grade T505
• For efficient cast iron turning
• Rhombic CNMG 80° geometry, 1.6 mm radius
• Double-sided chipbreaker, with central hole

Precision and economy in cast‑iron turning

The combination of a CVD‑coated surface and a cemented carbide substrate delivers a balance between wear resistance and cost efficiency for short to medium run operations. The applied coating reduces flank wear and sustains cutting edge integrity, which translates into longer tool life and fewer index changes; this is especially relevant when machining grey and nodular cast iron where thermal and abrasive stresses are common. The design therefore supports more predictable cycle times and lower process interruptions.

Compatibility, mounting and secure clamping

Compatibility with toolholders depends on insert form, clearance angle, tolerance class, clamping arrangement and plate thickness. The rhombic CNMG form with an 80° approach angle and a 0° clearance makes the insert suitable for standard CNMG turning holders; the central cylindrical hole supports positive clamping and repeatable locating. For systematic replacement and inventory control, the ISO designation clarifies fitment across matched holders and underlay/clamping sets.

Chip control, geometry and application benefits

A double‑sided chipbreaker matched to the T505 grade helps to control chip formation during interrupted and continuous cuts, reducing the risk of built‑up edge and improving surface finish. The 1.6 mm corner radius provides a compromise between edge strength and finishing capability, offering improved robustness on stability‑challenging setups while maintaining achievable surface quality. Where stable clamping and correct machining parameters are applied, the insert supports efficient material removal while keeping rework to a minimum.

FAQ

What materials is this insert best suited for?
The CNMG120416 T505 insert is intended primarily for cast‑iron machining; the T505 grade and CVD coating are optimised for efficient, economical turning of grey and nodular cast iron.

Is the insert compatible with standard CNMG toolholders?
Yes, the ISO CNMG120416 designation, 80° geometry and central cylindrical hole make it compatible with standard CNMG turning holders that accept ISO‑standard rhombic inserts.

How does the 1.6 mm corner radius affect cutting performance?
A 1.6 mm radius increases edge strength and reduces the risk of chipping in less rigid set‑ups while still allowing acceptable surface finishes when correct cutting parameters are chosen for the Tungaloy grade.

Can this insert be used for interrupted cuts?
The CVD‑coated cemented carbide grade T505 combined with a robust chipbreaker provides improved resistance during interrupted cuts, though cutting parameters should be adapted to the specific workpiece and setup.

What identifies the exact product for reordering?
Reorder using the ISO designation CNMG120416, grade T505 and manufacturer article number 6831204 (SKU 6831204‑Tungaloy) to ensure the correct Tungaloy indexable insert is supplied.
