CNMG120404 T9225 Tungaloy turning insert — CVD-coated carbide, 0.4 mm nose radius

A CNMG120404 T9225 Tungaloy insert for ISO-standard turning, designed for robust medium to heavy steel machining where variable engagement and interrupted cuts demand increased toughness.

• CVD-coated carbide T9225 grade
• Suitable for medium to heavy steel turning
• ISO CNMG120404 rhombic geometry, 80° cutting angle
• 0.4 mm nose radius with cylindrical hole

Reliable metal removal under variable conditions

The CVD-coated carbide T9225 grade provides a balance of toughness and wear resistance that benefits shops facing changing engagement and mixed cutting conditions. Its formulation is optimised for medium to heavy steel machining, so tool life is extended when compared with less resilient grades under the same loads. This results in more consistent cycle times and fewer insert changes, supporting higher process uptime and predictable production planning.

Geometry and dimensional consistency for precise turning

The rhombic CNMG form with an 80° cutting angle and 0.4 mm nose radius delivers stable cutting behaviour and a favourable combination of strength and access to turned contours. The standardised ISO designation ensures compatibility with ISO holders insofar as form, clearance angle, tolerance class, fastening method, size and thickness match, which simplifies tooling procurement and replacement cycles. Clear dimensional data aids in setting reliable machining parameters and reducing trial runs.

Chip control and handling advantages for efficiency

Equipped with a double-sided chipbreaker and a reversible design, the insert offers two usable cutting edges per side, improving stock utilisation and lowering tooling costs per edge. The cylindrical hole mounting gives secure seating in compatible clamping systems, helping to maintain repeatable positioning and surface finish. These features together support efficient chip evacuation and consistent surface quality in turning operations.

Practical selection and shop-floor integration

The insert integrates into common ISO turning systems as part of a simple assembly: the insert, a matching external holder or boring bar, a backing pad or clamp set and replacement screws. Selection of the chipbreaker and grade should be matched to workpiece material, cutting mode and machine stability to obtain the best compromise between tool life and cycle time. For shops transitioning to tougher grades, a short validation run will confirm optimal cutting data without lengthy setup cycles.

FAQ

Is this insert suitable for interrupted cuts in steel?
The CNMG120404 T9225 Tungaloy insert is designed for robust use in variable engagement and can handle mildly interrupted cuts thanks to the tougher T9225 grade.

Which holders are compatible with this geometry?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; use holders specified for ISO CNMG120404 geometry to ensure correct seating for the Tungaloy insert.

What does the T9225 grade signify for machining behaviour?
T9225 denotes a CVD-coated carbide grade engineered for a balance of toughness and wear resistance, offering stable performance in medium to heavy steel machining scenarios.

How many cutting edges are usable per insert?
The double-sided chipbreaker and reversible CNMG form provide multiple usable edges; the exact count depends on indexing strategy, but the design maximises edge utilisation.

Can this insert improve cycle consistency in production runs?
Yes, the combination of ISO geometry, dimensional standardisation and the T9225 coating supports repeatable cutting conditions and more consistent cycle times.
