CNMG 120416 T9215 Tungaloy turning insert — ISO turning insert, CVD-coated carbide

A CNMG120416 T9215 indexable insert designed for external and internal turning, optimised for medium steel and productive continuous to slightly interrupted cuts.

• CVD-coated carbide for high wear resistance
• Optimised for medium steel and productive turning
• Double-sided chipbreaker with rhombic 80° geometry
• Cylindrical hole for secure, repeatable clamping

Reliable performance for medium-steel turning operations

The CVD-coated T9215 grade combines carbide substrate strength with a robust coating to deliver extended tool life under continuous and lightly interrupted cutting conditions. This grade is presented as a balance between wear resistance and fracture toughness, making it a solid choice when consistent cycle times and predictable tool changes are priorities. With this performance profile, the insert supports higher productivity by reducing unscheduled tool interventions and maintaining stable cutting behaviour across batches.

Geometry and clamping that ensure repeatable stability

The rhombic 80° geometry and the 1.6 mm corner radius contribute to a predictable cutting edge engagement and dimensional control during turning. The insert is manufactured with a 0° clearance and a cylindrical hole, enabling straightforward fixation in standard ISO-compatible holders and boring bars. The plate thickness of 4.76 mm and the ISO designation ensure that holder compatibility is determined by form, clearance angle, tolerance class, fastening style, size and thickness—factors that together guarantee repeatable seating and reduced vibration when the system is set up correctly.

Shop-floor benefits: chip control and efficient tool economy

Equipped with a double-sided chipbreaker, the indexable insert offers improved chip formation and evacuation, which translates into consistent surface finishes and safer swarf handling. The double-sided nature of the plate delivers an economic advantage: two usable cutting edges per indexation, helping to lower tooling costs per part. Stable chip control also reduces the risk of rework and supports longer uninterrupted runs, which is particularly valuable in batch production or lights-out machining scenarios.

Integration guidance and system setup for reliable use

Successful implementation requires matching the chipbreaker and grade to the workpiece material and machining dynamics. The recommended system setup comprises the ISO-standard insert, a compatible external holder or boring bar, a support shim or clamp set, and appropriate fastening screws. Correct selection of holder geometry and stability class mitigates chatter and unlocks the T9215 grade’s potential for productive machining of medium steel. For machining strategies involving interrupted cuts or variable rigidity, choose the chipbreaker and holder that prioritise edge security over maximum cut depth.

FAQ

What materials is this grade best suited for?
The T9215 grade on the CNMG120416 insert is optimised for medium steel and combines wear resistance with fracture toughness for productive turning.

How is the insert secured in the holder?
The insert features a cylindrical hole for clamping and is designed for ISO-compatible holders; the CNMG120416 geometry ensures repeatable seating and secure fixation when used with the correct clamp set.

Can this insert be indexed for multiple edges?
Yes, the CNMG120416 is double-sided and indexable, offering multiple usable cutting edges to improve tool economy and reduce tooling costs per part.

What are the key dimensions to check for holder compatibility?
Important dimensions include the 12 mm insert size, 4.76 mm thickness and 1.6 mm corner radius; these must match the holder’s specifications for correct fit and seating.

Is this insert suitable for interrupted cuts?
The T9215 grade accommodates continuous to slightly interrupted cuts; for heavily interrupted machining, a different grade or reinforced clamping may be preferable.
