CNMG 120412 T9225 indexable turning insert by Tungaloy — CVD-coated carbide, rhombic 80° geometry

CNMG 120412 T9225 is a rhombic indexable insert designed for general turning applications, offering a sturdy CVD-coated carbide grade for demanding steel machining.

• CVD-coated carbide class T9225
• Universal grade for medium to heavy steel
• Rhombic CNMG 80° geometry
• Double-sided chipbreaker with hole

Consistent performance from a universal CVD-coated grade

The T9225 grade combines a CVD coating with a tough cemented carbide substrate to balance wear resistance and toughness. This makes the insert particularly suitable for medium to heavy steel machining where variable engagement and slight interruptions occur. The result is reliable edge life under changing cutting conditions, reduced downtime and fewer insert changes, which supports smoother production runs and predictable tooling costs.

Geometry and handling that support efficient turning

The rhombic CNMG form with an 80° approach angle and a 1.2 mm corner radius provides stable cutting behaviour and favourable chip flow for external and internal turning. The insert is double-sided, offering two usable edges per side, and features a cylindrical locating hole for secure clamping in compatible holders. The plate thickness 4.76 mm contributes to rigidity, reducing vibration and improving surface finish when paired with the correct toolholder and clamping set.

Practical system considerations and compatibility

These ISO-standard turning inserts fit into systems composed of the insert, a matching outer holder or boring bar, a support/clamp set and replacement screws. Compatibility depends on insert form, relief angle (0°), tolerance class, fastening style, size and thickness. Selecting the appropriate chipbreaker and grade for the workpiece material ensures optimal chip control and process stability, especially in production environments with varying cut conditions.

FAQ

What materials is this insert suitable for?
The CNMG 120412 T9225 insert is intended primarily for steel machining, optimised for medium to heavy cuts where toughness is required.

How does the T9225 grade affect tool life?
The T9225 CVD-coated grade offers a balance of wear resistance and toughness, which extends edge life under variable engagement compared with purely hard grades.

What holder features are required for correct fitment?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the insert requires a holder or boring bar designed for CNMG 120412 geometry and a suitable clamping set.

Is the insert suitable for interrupted cuts?
Yes, the universal nature of the T9225 grade provides increased toughness, making the insert resilient under slightly interrupted cuts and changing engagement conditions.
