CPMT09T308 T9225 Tungaloy turning insert — ISO rhombic insert for turning

The CPMT09T308 T9225 is an ISO rhombic turning insert engineered for medium to heavy steel turning where interrupted cuts or variable engagement demand enhanced toughness and reliable chip formation

• CVD-coated carbide T9225 for high toughness
• ISO rhombic CPMT geometry, 80° cutting angle
• 0.8 mm nose radius for robust surface finish
• Cylindrical hole with 40°–60° countersink

High productivity through a tough CVD-coated grade

The CVD-coated T9225 grade offers a balance of wear resistance and toughness well suited to demanding steel machining. Chemical vapour deposition forms a thin, adherent coating that protects the substrate during high-temperature contact, which reduces flank wear and extends edge life. For operations where cutting conditions vary or the cut is lightly interrupted, this carbide grade maintains edge integrity longer than uncoated counterparts, enabling fewer tool changes and a more economical production flow. The improved resistance to crater wear translates directly into consistent part quality and predictable tool-change intervals.

Stable cutting behaviour and improved surface quality

The rhombic CPMT geometry and the 80° approach angle provide a secure cutting profile for external and internal turning. A 0.8 mm nose radius contributes to a robust cutting edge and a reliable surface finish, while the 11° relief ensures appropriate clearance during tangential engagement. The insert’s one-sided chipbreaker helps form manageable chips in steel machining, reducing re-cutting and improving process stability. These geometric choices reduce vibration sensitivity and support higher material removal rates when paired with a suitable holder and machining parameters, so throughput and component consistency both improve.

Practical system compatibility and safe clamping

Supplied as an ISO-standard insert, compatibility with the toolholder is determined by form, relief angle, tolerance class, fastening method, size and thickness. The insert is designed with a cylindrical hole plus a 40°–60° countersink, facilitating repeatable clamping and straightforward replacement. The system comprises the ISO insert, matching external holder or boring bar, a backing pad or clamp kit and replacement screws; this modular approach simplifies spare-part planning. Clear identification of size (09), thickness (3.97 mm) and hole style reduces setup time and supports consistent, safe fixation in production environments.

FAQ

What materials is this insert suitable for?
The CPMT09T308 T9225 insert is intended primarily for steel machining; the T9225 grade is formulated for medium to heavy steel turning where toughness is required.

Can the insert cope with interrupted cuts?
Yes. The CVD-coated T9225 grade and the robust rhombic geometry of the insert provide the toughness needed for lightly interrupted or variable engagement cutting conditions.

How is the insert fixed in the holder?
The insert uses a cylindrical hole with a 40°–60° countersink for secure clamping; compatibility depends on holder form, tolerance class and fastening method.

Which chip formation can be expected with this insert?
The one-sided chipbreaker is designed to promote stable chip control in steel turning, reducing the risk of long, stringy chips and supporting uninterrupted production.

Is this insert compatible with ISO holders?
Yes. The CPMT09T308 is an ISO-standard rhombic insert; compatibility is confirmed by matching shape, size, thickness and fastening arrangement with the holder.
