CNMG090408 T515 – ISO turning insert, CVD-coated carbide (Tungaloy)

A CNMG090408 T515 indexable rhombic insert designed for economic external and internal turning of cast iron materials.

• ISO-compliant CNMG insert
• CVD-coated carbide T515
• Double-sided chipbreaker
• Cylindrical-hole, rhombic form

Consistent performance for cast iron machining

The CVD-coated carbide grade T515 delivers a balance of wear resistance and cost-effectiveness that is well suited to machining cast iron. The coating provides a wear-resistant surface layer which contributes to longer tool life and consistent cutting conditions over production runs. As a result, cycle times can be stabilised and tool change frequency reduced, supporting predictable production planning and lower total machining costs.

Stable seating and accurate repeatability in the toolholder

The CNMG rhombic geometry combined with the cylindrical hole and standard ISO form ensures secure seating in compatible holders. The insert’s 0° clearance angle and 80° cutting edge orientation give stable contact and reduced vibration when clamped correctly; this leads to improved surface finish and repeatable component tolerance. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so matching the insert to the correct external holder is essential for best results.

Practical setup and process advantages

Being double-sided, the insert offers two cutting edges per index, which increases economical usage and reduces tooling cost per edge. The nominal thickness of 4.76 mm and corner radius 0.8 mm are defined to support a range of cutting parameters, including interrupted cuts when paired with the appropriate chipbreaker. The supply concept comprises the ISO insert plus a matching external holder, shim/underlay, clamping set and replacement screws, enabling quick replacement and minimal setup downtime.

Application guidance and selection rationale

This grade and geometry are recommended where efficient chip formation and stable machining of cast iron are priorities. Selection of the chipbreaker and grade should follow the expected component stability, the degree of cut interruption and the required cutting speed. When correctly specified, the insert contributes to improved process security and an overall reduction in machining cost per part, particularly for batch production and series turning.
