CNMG 090408 T9215 ISO turning insert — CVD‑coated carbide by Tungaloy

A CNMG090408 T9215 ISO‑format turning insert engineered for medium‑steel machining, optimised for continuous to lightly interrupted cuts.

• CVD‑coated carbide for high wear resistance
• 0.8 mm corner radius for consistent edge strength
• Double‑sided chipbreaker for multiple indexable edges
• ISO‑compliant rhombic insert with cylindrical hole

Consistent productivity through wear‑resistant carbide

The CVD‑coated carbide grade T9215 combines elevated wear resistance with maintained fracture toughness, making it a dependable choice for sustained turning operations in medium‑strength steels. The coating reduces flank and crater wear under continuous cutting conditions, which translates into longer tool life and fewer tool changes. This reliability supports higher machine utilisation and predictable process planning, directly contributing to lower cycle time variation and improved throughput.

Geometry and chip control that reduce rework

The rhombic plate form with an 80° included angle and the integrated double‑sided chipbreaker deliver stable chip formation and evacuation. The 0.8 mm corner radius is optimised to resist edge chipping while producing acceptable surface finish in typical finishing and semi‑finishing passes. The 0° relief angle provides a neutral clearance geometry that helps maintain dimensional accuracy on external and internal turning, reducing the need for secondary finishing and thus lowering rework rates.

System compatibility that simplifies setup

As an ISO‑standard insert, compatibility with holders is determined by form, relief, tolerance class, fastening, size and thickness; the insert thickness of 4.76 mm and the cylindrical hole allow secure clamping in a wide range of ISO holders and boring bars. The double‑sided construction increases indexable edge count per insert, improving cost efficiency per cutting edge. Selecting the matching holder and clamping set ensures repeatable seating and stable cutting conditions, which is essential for consistent part quality in series production.

Application guidance for effective use

Designed primarily for turning, the grade is recommended for medium steel where a balance of tool life and toughness is required; it performs best in continuous to lightly interrupted cuts. For interrupted or heavy roughing, consider adapting feed and depth of cut or selecting a different grade optimised for higher impact resistance. The insert is supplied in the ISO‑turning system and is compatible with the usual replacement screws and clamping sets; correct torque and clean seating surfaces ensure the maximum life from each indexable edge.

FAQ

What materials is this insert suitable for?
The CNMG090408 T9215 insert is formulated for medium steel machining, delivering an effective balance between wear resistance and toughness for continuous to slightly interrupted turning.

How does the double‑sided chipbreaker affect tool economy?
The double‑sided chipbreaker on the Tungaloy insert provides multiple indexable edges, increasing the usable life per insert and improving cost per cutting edge.

Which holder features are required for correct compatibility?
Compatibility depends on holder form, relief, tolerance class, fastening, size and thickness; secure seating with the correct clamping set and replacement screw is essential for the CNMG090408 T9215 to perform reliably.

Is this insert suitable for interrupted cuts?
The T9215 grade is optimised for continuous to lightly interrupted cutting; for frequent heavy interruptions, a tougher grade should be considered.

What are the benefits of the CVD coating on this insert?
The CVD coating on the CNMG090408 T9215 enhances wear resistance and assists in maintaining edge stability, which supports longer tool life and more stable machining results.
