CPMT 080204 T9225 — Indexable Turning Insert for Turning, Tungaloy

CPMT080204 T9225 is a rhombic ISO insert designed for external and internal turning in steel, offering a robust universal grade for changing cutting conditions

• CVD-coated carbide for stable wear resistance
• 80° rhombic geometry for versatile turning
• 11° clearance angle for secure cutting engagement
• 0.4 mm corner radius for fine profile control

Consistent performance under variable cutting conditions

The T9225 grade is a CVD-coated carbide formulation developed for robust, universal performance in medium to heavy steel machining. Its chemical vapour deposition coating increases surface hardness while preserving substrate toughness, which helps resist built-up edge and extends tool life under interrupted cuts. This results in steadier cycle times and fewer index changes, making the insert suitable where moderate to demanding engagement conditions appear. The described grade supports productive material removal while offering predictable wear behaviour, so setup adjustments can focus on process optimisation rather than compensating for rapid tool degradation.

Secure clamping and ISO compatibility for repeatable results

Compatibility with toolholders depends on geometry, clearance, tolerance and fastening. The insert features an 80° rhombic geometry, a 0.4 mm corner radius and a 2.38 mm thickness, with a cylindrical hole and one-sided countersink (40°–60°) that help ensure positive locating and clamping stability in a matched holder. The 11° clearance angle reduces rubbing on the flank and supports reliable surface finish when the assembly is correctly matched. These defined dimensions follow ISO norms for indexable turning inserts, so integrating the component into an existing holder system is straightforward provided the form, size and tolerances correspond.

Productive machining and practical system design

The system build for indexable turning relies on the insert, appropriate external holder or boring bar, and a secure clamping kit with spare screws. The CPMT080204 insert is intended to be used with a compatible chipbreaker and grade selection according to material, cutting mode and machine stability. A one-sided chipbreaker assists in chip control during external and internal turning, reducing the risk of entanglement and improving surface consistency. Choosing this universal carbide grade minimises tool inventory complexity while enabling a wide application range; fewer insert types can cover variable jobs without compromising productivity.

FAQ

What holder features are required for correct mounting of the insert? For correct mounting the CPMT080204 Tungaloy indexable turning insert (SKU 6781316-Tungaloy) requires a holder matching the plate form, diameter, thickness 2.38 mm, clearance 11° and the screw/locating design for the cylindrical hole with countersink.

Which materials is this grade best suited for? The T9225 grade on the CPMT080204 insert is formulated for robust performance in steel, especially for medium to heavy operations and situations with slightly interrupted cuts where enhanced toughness is beneficial.

How does the chipbreaker affect machining performance? The one-sided chipbreaker reduces long swarf and improves chip control during both external and internal turning; using the recommended chipbreaker for the workpiece stability leads to a more consistent surface finish with fewer manual interventions.

Is the insert usable for interrupted cuts and mixed engagement conditions? Yes, the CVD-coated carbide composition and T9225 grade are chosen for stable chip formation and increased toughness, making the insert suitable for interrupted cuts and variable engagement during production.

What dimensional features influence surface finish and profile accuracy? Key dimensions such as the 0.4 mm corner radius, 80° rhombic geometry and 11° clearance angle determine contact behaviour and flank support, which together influence surface finish and profile fidelity during turning operations.
