CPMT 09T304 T9215 — ISO turning insert for turning (Tungaloy)

The CPMT09T304 is an ISO rhombic turning insert engineered for external and internal turning, combining a CVD-coated carbide grade with an 80° geometry for stable, productive machining of medium steel.

• CVD-coated carbide T9215
• ISO rhombic insert CPMT09T304
• 11° relief angle for secure cutting
• 0.4 mm corner radius for profile control

High wear resistance and consistent productivity for medium steel

The T9215 grade is a CVD-coated carbide designed as a first choice for medium steel machining, combining elevated wear resistance with good fracture toughness. This balance enables sustained performance during continuous to slightly interrupted cuts, reducing the frequency of tool changes and improving overall process efficiency. The coating supports consistent surface quality and predictable tool life, which in turn contributes to lower unit costs and steadier production output.

Stable clamping and geometrical precision for repeatable results

The rhombic plate shape with an 80° included angle and 11° relief provides mechanical strength and favourable cutting engagement when used in the correct clamping system. The insert’s 0.4 mm corner radius and a plate thickness of 3.97 mm deliver positive support at the cutting edge, while the cylindrical hole with one-sided countersink (40°–60°) ensures repeatable seating and secure fixation. Compatibility with a toolholder requires matching form, relief angle, tolerance class, fixation method, size and thickness; correct pairing results in improved dimensional stability and reduced vibration.

Application guidance and process advantages for workshop use

Designed for general turning, the insert performs well in both external and internal operations when paired with the appropriate chipbreaker and holder. The single-sided chipbreaker enhances chip control for typical turning feeds used on medium steels, helping to avoid chip entanglement and to maintain consistent surface finish. Selecting the right holder geometry and clamping torque capitalises on the insert’s CVD-coated surface and carbide substrate, delivering predictable wear behaviour and enabling productive, repeatable machining cycles with low setup effort.

FAQ

What workpiece materials is this insert suitable for?
The CPMT09T304 T9215 Tungaloy insert is optimised for medium steel machining; its CVD coating and carbide substrate make it particularly suitable for continuous to slightly interrupted cuts in these materials.

Which toolholder types are compatible with this insert?
Compatibility depends on matching the insert form, 11° relief angle, tolerance class, fixation and size; use holders specified for ISO rhombic CPMT inserts to ensure secure clamping.

What does the 0.4 mm corner radius affect in practice?
A 0.4 mm corner radius provides a balance between edge strength and profile definition, improving edge life while preserving the ability to machine small radii and shoulder transitions.

Can this insert handle interrupted cuts?
Yes, the T9215 grade combines wear resistance with fracture toughness, making it suitable for continuous and slightly interrupted cutting conditions; heavily interrupted cuts may require alternative grades.

How does the single-sided chipbreaker benefit turning operations?
The single-sided chipbreaker is designed to control chip formation under typical turning feeds for medium steel, reducing chip flow issues and supporting consistent surface finish.
