CNMG160616 T515 indexable turning insert by Tungaloy — ISO turning grade for cast iron machining

CNMG160616 T515 is an ISO-standard, rhombic indexable insert designed for external and internal turning in cast iron applications. Its geometry and grade are matched to holders that comply with ISO form, relief angle, tolerance and fastening dimensions.

• ISO rhombic insert, 80° geometry
• CVD-coated carbide grade T515
• 1.6 mm corner radius for robust cuts
• Double-sided chipbreaker, cylindrical hole

Reliable performance with a CVD-coated carbide grade

The CVD-coated carbide composition of this grade offers a balanced combination of wear resistance and toughness that is particularly suited to economical machining of cast iron. The coating helps to reduce flank wear and improves heat resistance during sustained cutting, which results in a longer tool life and more predictable performance in series production. For operations where machining economy and consistent cycling are priorities, this grade provides measurable advantages in process stability.

Geometry and mounting that ensure secure seating and repeatability

Built to the ISO profile CNMG form, the insert features an 80° rhombic geometry and a 1.6 mm corner radius that contribute to robust edge strength and versatile turning capability. The plate thickness of 6.35 mm and the cylindrical hole with a matching seating design ensure precise clamping and repeatable positioning in compatible holders. Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness, so pairing the insert with the correct holder and shim is essential for stable machining.

Chip control engineered for cleaner cuts and surface quality

The double-sided chipbreaker integrated into the cutting face supports controlled chip formation across a range of cutting conditions, helping to avoid long, stringy chips and to maintain a consistent surface finish. Optimised chip control reduces the risk of re-cutting and supports higher feed rates where machine and workpiece rigidity allow. For interrupted cuts or unstable setups, selecting the appropriate chipformer and adapting cutting parameters will contribute directly to process reliability.

System-level compatibility for efficient tool management

As part of an ISO indexable system, the insert is intended to be used with a matching holder, suitable underlay/shim and the correct clamping screw set. This system approach simplifies inventory and reduces set-up times because inserts and holders designed to ISO specifications are interchangeable across many tool platforms. Checking the holder form and tolerance ensures accurate seat contact and consistent cutting edge orientation in repetitive production tasks.

Economic benefits through targeted application and selection

This grade is developed for the economical machining of cast iron where production throughput and stable chip formation are priorities. Selecting the T515 grade and the CNMG geometry allows for competitive cutting speeds while maintaining predictable wear characteristics. When stability, interrupted cuts or higher cutting speeds are factors, choosing the right combination of grade and chipbreaker will often result in lower per-part tool costs and more efficient cycle times.

Practical selection tips and recommended checks before use

Choose the specific chipbreaker and grade variant based on the workpiece material, the presence of interruptions and the rigidity of the machine set-up. Verify holder compatibility against the ISO form, the 0° relief angle and the plate dimensions before installation. The insert designation CNMG160616 indicates the form and size; confirm this against the holder specifications and ensure proper clamping to gain the expected repeatability and cutting performance.
