CNMG 090408 T9215 turning insert for ISO turning — Tungaloy

CNMG090408 T9215 Tungaloy-Wendeplatte is an ISO-standard indexable insert designed for turning applications in medium steel environments, offering a balance of wear resistance and fracture toughness.

• CVD-coated cemented carbide T9215
• For medium steel machining
• Double-sided chipbreaker for stability
• Rhombic CNMG 09 form, 80° lead angle

Consistent tool life through engineered cutting material

The T9215 grade is a CVD-coated cemented carbide developed to combine high wear resistance with excellent fracture toughness. For medium steel machining, this results in longer intervals between tool changes and more predictable component quality. The coating reduces flank wear at typical cutting speeds, while the substrate tolerates the mechanical loads of continuous to slightly interrupted cuts, improving overall productivity and process stability.

Geometry that improves stability and surface finish

The rhombic CNMG090408 geometry with an 80° lead angle and a 0.8 mm corner radius is optimised for robust cutting and consistent surface integrity. The double-sided chipbreaker controls chip formation to prevent entanglement and assists coolant penetration, which helps maintain low cutting forces and a steady surface finish. The 0° clearance ensures reliable seating in compatible toolholders and supports repeatable positioning for serial production.

ISO compatibility and secure clamping

As an ISO-standard indexable insert, compatibility with a holder depends on matching form, clearance angle, tolerance class, fastening method, size and plate thickness. The plate is supplied with a cylindrical hole, enabling positive clamping in many ISO holders and shanks. A system comprising the insert, a matched external holder or boring bar, a shim or clamp and the correct fixing screw ensures a secure assembly and consistent cutting geometry across tool changes.

Operational advantages for production environments

In serial and job-shop settings the insert delivers a pragmatic mix of economy and performance: longer tool life from the T9215 compound, stable machining from the plate geometry and reduced downtime from its indexable, double-sided design. These characteristics support higher machine utilisation and predictable process outcomes, giving a straightforward route to improved throughput and repeatable quality in turning operations.

FAQ

What materials is this insert best suited for?
The CNMG090408 T9215 Tungaloy insert is optimised for medium steel machining and performs well in continuous to slightly interrupted turning operations.

How is the insert mounted in a toolholder?
The plate is supplied with a cylindrical hole and must be clamped in an ISO-compatible holder; compatibility depends on matching form, clearance, tolerance class, fastening method, size and thickness.

What advantages does the T9215 grade provide?
T9215 is a CVD-coated cemented carbide offering a balance of wear resistance and fracture toughness, which supports higher productivity and more consistent tool life in medium steel turning.

Is the insert indexable on both sides?
Yes — the insert features a double-sided chipbreaker, allowing it to be indexed and reused on the reverse face for extended service life.

Which insert designation should be specified when ordering?
Specify the ISO designation and grade: CNMG090408 T9215 (Tungaloy) or use the article number 6797188 for exact identification.
