Stable cutting with a tough, universal grade

The T9225 grade is a CVD‑coated carbide developed for robustness in medium to heavy steel machining. Its formulation favours increased toughness, which translates into fewer fractured edges when engagement conditions change or cuts are slightly interrupted. The double‑sided chipbreaker supports consistent chip formation, reducing the need for unscheduled tool changes and helping to secure a more predictable tool life. In practical terms, this means longer uninterrupted production runs and improved process reliability when turning demanding components.

ISO geometry for predictable holder compatibility and accuracy

An ISO‑conforming CNMG geometry ensures straightforward matching to suitable external holders or boring bars; compatibility is governed by form, clearance angle, tolerance class, fastening, size and thickness. The insert’s 0° free angle and an included angle of 80° deliver stable cutting forces and accessible cutting edges for a broad range of external and internal turning tasks. The 0.8 mm corner radius balances edge strength and surface finish, while the rhombic shape and cylindrical hole facilitate secure clamping and simple indexation. Standardised geometry reduces setup time and simplifies spare‑part management across production lines.

System benefits that increase workshop productivity

Supplied as part of an insert system — insert, compatible holder or bar, clamping pad and fastening screws — this solution supports quick replacement and inventory control. The CVD coating adds oxidation and abrasion resistance at elevated cutting speeds, improving surface quality on turned parts and reducing rework. Because the grade is optimised for varying cutting conditions, it is particularly suitable where operators require a single, dependable insert to cover a range of turning operations. For customers seeking process stability and fewer interruptions, this grade offers a pragmatic balance between performance and economy.

FAQ

What machining tasks is this insert most suited for?
The CNMG120408 T9225 insert from Tungaloy is intended for external and internal turning, especially medium to heavy steel machining where interrupted cuts or variable engagement demand a tougher grade.

How does the T9225 grade affect tool life?
Tungaloy’s T9225 CVD‑coated carbide provides enhanced toughness and wear resistance, which supports predictable tool life and reduces edge chipping under fluctuating cutting conditions.

Can this insert be used with standard CNMG holders?
Yes. The CNMG120408 follows ISO geometry, so compatibility with CNMG holders and boring bars is determined by form, clearance, tolerance class, fastening, size and thickness.

What surface finish can be expected with this insert?
With the CVD coating and appropriate cutting parameters, the insert achieves good surface quality on steel components while maintaining robust edge performance for longer cycles.

Is the insert indexable and easy to replace during production?
The insert is double‑sided and indexable; its rhombic shape and cylindrical hole enable secure clamping and straightforward indexing, facilitating quick replacements within an insert system.
