CNMG120408 T9215 — CNMG indexable turning insert, CVD-coated carbide (Tungaloy)

The CNMG120408 T9215 is an ISO-standard indexable insert designed for external and internal turning, combining durable CVD-coated carbide with a double-sided chipbreaker for productive, continuous and lightly interrupted cuts.

• CVD-coated cemented carbide for high wear resistance
• Suited to medium steel machining with reliable toughness
• Double-sided chipbreaker for continuous and interrupted cuts
• Rhombic CNMG form, 80° approach, 0.8 mm corner radius

Reliable performance for medium-steel turning

The CVD-coated cemented carbide grade T9215 is specified for demanding, mid-range steel machining where a balance of wear resistance and edge strength is required. The coating and substrate pairing reduce flank and crater wear under continuous cutting, which translates into fewer indexings and longer uninterrupted production runs. This performance-oriented combination supports higher material removal rates without sacrificing component quality or process stability.

Designed for holder compatibility and secure clamping

Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic CNMG geometry with an 80° approach and a 0° clearance angle fits ISO-compliant holders when matched for the 12 mm inscribed circle and 4.76 mm thickness. The insert is supplied with a cylindrical locating hole for precise seating; selection of a matching external holder, clamp set and replacement screws completes the system and ensures repeatable positioning and secure clamping under load.

Improved chip control and predictable cutting behaviour

The double-sided chipbreaker is engineered to manage chip formation across continuous and slightly interrupted cuts, supporting stable chip evacuation and heat distribution. The chipformer geometry reduces the risk of built-up edge and promotes consistent cutting forces, which helps maintain surface finish and dimensional accuracy during longer cycles. Predictable chip control also benefits tool life planning and reduces unplanned stoppages in serial production.

Practical geometry for durable edges and efficient handling

A corner radius of 0.8 mm provides a robust cutting edge that resists chipping on profile changes, while the 4.76 mm plate thickness contributes to edge support and stability. The rhombic form enables straightforward indexing and multiple usable cutting corners, increasing cost-efficiency per insert. For workshops pursuing steady throughput in steel turning, this insert offers a combination of mechanical strength, usable cutting life and straightforward integration into ISO tool systems.
