CNMA 160612 T5115 turning insert by Tungaloy — CVD-coated carbide, rhombic 80° design

CNMA 160612 T5115 is an ISO‑standard indexable insert for precision turning, designed primarily for external and internal turning of cast iron and similar components.

• ISO rhombic insert CNMA 160612
• CVD-coated carbide grade T5115
• 80° approach angle, 0° relief angle
• With cylindrical hole for secure clamping

Consistent cutting performance for cast-iron turning

The CVD‑coated carbide grade T5115 combines wear resistance with stable cutting-edge behaviour, making it suited to a wide range of cast‑iron turning tasks. The coating reduces abrasive wear under interrupted cuts, while the substrate carbide sustains the cutting edge under elevated temperatures. This results in fewer insert changes and improved process efficiency, translating to lower machine downtime and steadier cycle times for serial production.

Secure clamping and dimensional reliability for repeatable parts

The rhombic 16 mm insert with an 80° approach angle and with a cylindrical hole delivers a precise fit in compatible ISO turning holders. The plate thickness of 6.35 mm and the 1.2 mm corner radius ensure mechanical stability and repeatable part geometry, even under moderate cutting forces. Compatibility is determined by form, relief angle, tolerance class, fastening and plate dimensions, so the system approach—insert, holder and clamping kit—is essential for predictable outcomes.

Productivity through geometry and coating rather than aggressive parameters

Although the insert lacks an integrated chipbreaker, the balanced edge preparation and CVD coating make it effective for controlled chip formation when matched to suitable cutting parameters and fixture stiffness. Choosing the correct feed and depth of cut for the workpiece and rigidity of the setup will yield improved surface finish and prolonged tool life. The universal character of the grade supports a broad material coverage, simplifying tool selection across mixed cast‑iron work.

Practical support and selection guidance for process optimisation

Selection of chipbreakers and cutting grades should reflect workpiece material, machining strategy and machine stability. For customers requiring tailored advice, the technical description highlights the major dimensions and functional aspects to verify holder compatibility. Metav Werkzeuge’s team can help match holders, clamping sets and spare screws to ensure the insert’s benefits are realised in daily production — from single‑piece prototypes to high‑volume batches.

FAQ

What materials is this insert suited for? The CNMA160612 T5115 insert is formulated as a universal grade for cast iron machining, offering a balanced combination of wear resistance and edge stability for typical cast‑iron turning tasks.

Does the insert require a specific holder? Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the CNMA160612 geometry and cylindrical hole fit standard ISO turning holders designed for rhombic inserts.

What are the key dimensions to check before ordering? Verify insert size 16 mm, plate thickness 6.35 mm, corner radius 1.2 mm and the 80° approach angle to ensure correct fit and clamping in the selected turning system.

Is there a chipbreaker on this insert? This grade is supplied without an integrated chipbreaker; chip control should be achieved by selecting appropriate cutting parameters or by pairing the insert with a holder/chip control design suited to the operation.

How does the CVD coating benefit production? The CVD coating on the carbide substrate reduces abrasive wear and supports stable cutting edges during interrupted or elevated‑temperature cuts, improving tool life and process consistency for cast‑iron operations.
