CNMG 090408 T9215 Turning — Tungaloy indexable insert for turning

CNMG090408 T9215 Tungaloy indexable insert for ISO‑standard turning applications, engineered for medium steel machining with a robust, CVD‑coated cemented carbide grade.

• CVD-coated carbide grade T9215
• Rhombic CNMG090408 form with hole
• 0.8 mm corner radius for edge strength
• Double-sided chipbreaker for productivity

Increased productivity with a wear‑resistant grade

The T9215 grade combines a CVD coating with a tough cemented carbide substrate, providing a measured balance between wear resistance and fracture toughness. For shops focused on sustained material removal rates, this means fewer indexings and less unplanned downtime. The coating reduces abrasive wear on the cutting edge while the substrate absorbs intermittent shock, making the insert particularly well suited to continuous and slightly interrupted turning cycles. The result is a predictable tool life and consistent component quality.

Secure seating and ISO compatibility for stable machining

Designed in the ISO CNMG family, the rhombic CNMG090408 form and the cylindrical‑hole fastening ensure compatibility with a wide range of ISO‑compliant holders. Correct fit is determined by form, clearance angle, tolerance class, fastening method, size and thickness; a compliant system reduces chatter and improves surface finish. The 0° clearance angle and 80° included angle contribute to a stable contact geometry, which supports repeatable set‑ups and straightforward tool management across production batches.

Optimised geometry for medium steel and robust cutting

The double‑sided chipbreaker geometry and the 0.8 mm corner radius offer a compromise between strength and profile accuracy: the radius provides enhanced edge strength for semi‑roughing, while the chipformer helps control swarf and maintain consistent cutting forces. In practice, this means improved cycle times on shaft turning and facing operations in medium‑hard steels, with fewer tool‑related rejections and better surface integrity on the finished part.

Practical handling and predictable tool life

With a plate thickness of 4.76 mm and a compact size 09 form factor, the insert is easy to store and rotate for full utilisation of both cutting faces. The CVD coating simplifies reconditioning timelines by delaying flank wear, and the double‑sided format doubles the available cutting edges per insert. For production planners this yields a straightforward stock rotation and predictable replacement intervals, supporting efficient inventory control and lower overall machining costs.

FAQ

What materials is this insert intended for?
The CNMG090408 T9215 Tungaloy indexable insert is primarily intended for medium steel machining; the T9215 grade combines wear resistance and toughness for productive steel turning.

How is the insert mounted and secured?
Mounting follows ISO standards for CNMG inserts: the rhombic plate with a cylindrical hole is secured in a compatible insert seat with the appropriate clamp or screw to ensure correct positioning and repeatability.

Can this insert handle interrupted cuts?
Yes, the CVD‑coated carbide substrate and the T9215 grade provide fracture resistance suited to continuous and lightly interrupted cutting conditions in steel turning.

How many cutting edges are available per insert?
The plate is double‑sided with a chipbreaker on both faces, allowing two indexed cutting edges per face depending on the seat and orientation, which increases usable edge count versus single‑sided designs.

Is this insert compatible with standard CNMG holders?
Compatibility with holders depends on form, clearance angle, tolerance class, fastening and size; the CNMG090408 form is an ISO standard and fits holders designed for CNMG inserts when dimensions and tolerances match.
