CNMG090408 T9215 CNMG turning insert, CVD-coated carbide – Tungaloy

A CNMG090408 T9215 ISO rhombic turning insert designed for external and internal turning in medium-steel applications, offering high wear resistance and consistent chip control.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• Rhombic CNMG 09 geometry
• Double-sided chipbreaker design
• Cylindrical hole for secure clamping

Consistent productivity through a wear-resistant grade

The CVD-coated T9215 grade combines a wear-resistant coating with a robust carbide substrate to extend tool life in continuous and slightly interrupted cuts. This results in fewer indexings and longer intervals between insert changes, which supports a smoother production flow and predictable process windows. The proven balance of wear resistance and fracture toughness enables more aggressive feeds or extended cycles without sacrificing component quality.

Precision and surface finish from the CNMG geometry

The rhombic CNMG geometry with an 80° angle and a 0.8 mm corner radius promotes stable contact conditions and reduced cutting forces during external and internal turning. This geometry is particularly effective when a reliable workpiece surface is required after roughing or semi-finishing passes. The modest corner radius helps to maintain dimensional accuracy while the insert form contributes to improved tool life and repeatable surface quality in series production.

Efficient chip control and secure clamping for process stability

Equipped with a double-sided chipbreaker, the insert supports controlled chip formation across a range of cutting data, reducing interruptions and the risk of built-up edge. The insert’s cylindrical hole and ISO-compliant dimensions ensure positive clamping in compatible holders, increasing assembly reliability and minimising runout. Together, these features reduce downtime and contribute to higher effective machine utilisation.

Integration guidance for easy adoption in turning cells

As an ISO-standardised insert, the part integrates into common tool systems where holder form, clearance angle, tolerance class, fastening and thickness match the insert specification. Selection of the correct chipbreaker and grade for the workpiece material and machining stability is essential; the CVD-coated grade here is the first choice for medium steel machining and supports productive cutting strategies. If process optimisation is needed, choosing appropriate holder rigidity and cutting data will unlock the full benefit of the insert’s design.

FAQ

What materials is this insert best suited for?
The Tungaloy CNMG090408 T9215 insert is optimised for medium steel machining; the CVD-coated T9215 grade provides high wear resistance combined with good fracture toughness for continuous to lightly interrupted cuts.

How does the chipbreaker affect productivity?
The double-sided chipbreaker on this CNMG insert promotes controlled chip formation and evacuation, which reduces process interruptions and supports longer uninterrupted production runs when matched with correct cutting data.

Can this insert be used in standard ISO holders?
Yes, the CNMG090408 follows ISO dimensions for rhombic inserts; compatibility depends on matching holder form, clearance angle, tolerance and fastening—secure clamping is achieved via the cylindrical hole.

What surface quality can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius offers a balance between tool strength and surface finish, giving improved dimensional stability and a finer surface compared with larger radii while maintaining robust performance in production.
