CNMG 120404 T9215 indexable insert for Turning — Tungaloy

CNMG120404 T9215 indexable insert for ISO‑standard turning, designed for medium‑steel machining with high productivity in continuous to slightly interrupted cuts.

• CNMG120404 geometry, 80° rhombic shape
• CVD-coated carbide grade T9215
• Double-sided chipbreaker for consistent chips
• Suited to continuous and light interrupted cuts

Reliable cutting performance for productive turning

The CNMG120404 T9215 indexable insert combines a robust CVD-coated carbide substrate with an 80° rhombic geometry to deliver steady metal removal rates in turning operations. The chosen grade balances wear resistance with fracture safety, which translates into longer tool life and fewer unexpected interruptions on the shop floor. For manufacturing environments prioritising throughput, this insert supports sustained productivity and predictable replacement intervals.

Secure seating and compatibility with ISO holders

Compatibility with the toolholder is determined by form, clearance angle, tolerance class, fastening, size and thickness; this ISO‑standard insert features a rhombic form with a cylindrical centre hole to ensure consistent clamping in matched holders. The 0° clearance angle and 80° main cutting edge provide geometric stability during engagement, reducing vibration and improving repeatability. Clear guidance on holder matching reduces setup time and supports reproducible machining results.

Optimised chip control and material focus

Equipped with a double-sided chipbreaker, the insert produces controllable chips that aid evacuation and surface finish when machining medium steel. The chipformer design is matched to the T9215 grade to work effectively across continuous to lightly interrupted cuts, lowering the risk of built-up edge and helping maintain consistent component quality. The result is smoother cycles and fewer downstream processes required for finishing.

Handling, tool economy and operational benefits

The insert’s reversible, double-sided construction allows index changes instead of immediate replacement, increasing effective life per item and reducing tooling costs per component. Combined with the grade’s wear characteristics and the rhombic 80° geometry, users gain a stable cutting edge that supports higher cutting speeds and longer intervals between inspections. For production planning, this means improved machine uptime and a better return on tooling investment.

FAQ

What materials is this insert optimised for?
The CNMG120404 T9215 insert is optimised for machining medium steels; the T9215 grade provides a balance of wear resistance and fracture safety suited to continuous to lightly interrupted turning.

How is chip control achieved with this insert?
Chip control is achieved via the built‑in double‑sided chipbreaker, which, in combination with the CVD coating and grade geometry, promotes consistent chips and improved surface finish during steady cuts.

Can this insert be used with interrupted cuts?
Yes, the insert grade and geometry are suitable for continuous and light interrupted cuts; for heavy interruptions, review holder rigidity and cutting parameters before application.

How many cutting edges are available per insert?
The rhombic, double‑sided design provides multiple effective cutting edges per indexable insert, enabling reindexing to extend usable life before replacement.

What must be checked for holder compatibility?
Compatibility requires matching the insert form, clearance angle, tolerance class, fastening method, size and thickness to the holder; ensure the holder is ISO‑compatible for the CNMG120404 form.
