CPMT 09T302 T9225 Turning insert — ISO CPMT indexable insert for turning by Tungaloy, CVD-coated carbide, 0.2 mm radius

CPMT09T302 T9225 is an ISO-standard indexable insert for turning applications, designed for medium to heavy steel machining where variable engagement or slightly interrupted cuts demand additional toughness.

• CVD-coated T9225 grade for increased toughness
• ISO CPMT geometry, compatible with standard holders
• 0.2 mm corner radius for fine edge control
• Designed for medium to heavy steel turning

Dependable performance for demanding steel turning

The CVD-coated T9225 grade provides a balance of wear resistance and toughness tailored to medium and heavy steel machining. By combining a carbide substrate with a multi-layer CVD finish, the cutting edge resists abrasive wear while retaining sufficient edge strength for variable cutting conditions. This results in consistent tool life under mixed engagement and intermittent cutting, reducing unplanned insert changes and improving process stability.

Easily integrates with ISO tooling systems for predictable setup

The insert features the ISO CPMT geometry with a rhombic form, a 11° relief and 80° main angle; these dimensions ensure compatibility with a wide range of standard holders when form, relief angle, tolerance class, clamping method, size and thickness match. The 3.97 mm thickness and the presence of a hole with a cylindrical bore plus a single-side countersink (40°–60°) simplify clamping reliability, while the standard size designation supports straightforward procurement and inventory management.

Precise edge control and optimised chip formation

A 0.2 mm corner radius combined with a one-sided chipbreaker gives controlled cutting edge geometry for fine to moderate finishing passes and predictable chip flow in steel turning. The single-sided chipbreaker promotes stable chips under heavier feeds, lowering the risk of edge damage during short interruptions. Choosing the right chipbreaker and grade aligns surface finish targets with productivity goals, enabling a clearer trade-off between material removal rate and final surface quality.

Application guidance and system considerations

As a universal, robust grade, T9225 suits a wide range of steel turning tasks where varying engagement or light interruptions occur; the insert is intended to be used together with a matching external holder or boring bar, a proper backing/locating pad and replacement clamping screws. For best results, select tooling parameters that reflect the insert’s strength—moderate cutting speeds with appropriate feed and coolant strategy deliver the best mix of tool life and productivity. For compatibility checks, Metav Werkzeuge can advise on holder fit and clamping sets to ensure correct seat and tolerance match.

FAQ

What materials is this insert suited to machine?
The CPMT09T302 Tungaloy indexable insert in T9225 is designed primarily for medium to heavy steel turning, offering toughness for variable engagement and slightly interrupted cuts.

How does the T9225 grade improve performance compared with standard grades?
The T9225 grade on the CPMT09T302 insert combines CVD surface hardness with a tougher substrate to provide better resistance to chipping under interrupted cuts and stable wear behaviour in heavier steel machining.

Which holder features are required for secure clamping?
Compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; the CPMT09T302 insert requires a matching CPMT holder or boring bar, a backing/locating pad and appropriate screws for secure clamping.

Can the insert handle interrupted cuts or roughing operations?
Yes, the CVD-coated T9225 variant of the CPMT09T302 is intended for robust universal use and can withstand interrupted cuts and roughing in medium to heavy steel applications thanks to its enhanced toughness.

What effect does the 0.2 mm corner radius have on surface finish and strength?
The 0.2 mm corner radius provides a good compromise between edge strength and surface finish: it improves edge robustness for heavier engagement while enabling acceptable surface quality on finishing passes.
