CPMT09T308 T9215 Tungaloy indexable turning insert — CVD-coated carbide, 0.8 mm corner radius

The CPMT09T308 indexable insert is a rhombic ISO turning insert designed for productive external and internal turning of medium steels; compatible with ISO holders when matched for form, relief angle, tolerance class, clamping and thickness.

• CVD-coated carbide grade T9215
• Suited for medium steel and light interruption cuts
• Rhombic shape with 80° edge and 0.8 mm radius
• Cylindrical hole with single-sided countersink (40°–60°)

Productive medium-steel turning with a wear-resistant grade

This insert uses the T9215 CVD-coated carbide formulation to combine enhanced wear resistance with fracture toughness, making it a reliable choice for sustained production runs. The coating reduces flank and crater wear under typical turning parameters, extending tool life and reducing tool-change frequency. For operations that demand consistent throughput, the grade supports continuous to lightly interrupted cutting, translating coating and substrate performance directly into lower manufacturing cost per part.

Stable edge geometry for consistent surface finish and tool life

The rhombic insert geometry and the 0.8 mm corner radius deliver a balance between edge strength and achievable surface finish. A larger corner radius increases edge support for higher feeds, while the 11° relief angle reduces rubbing and stabilises cutting forces. The single-sided chipbreaker controls chip form for medium steels, which simplifies chip evacuation and helps maintain a repeatable surface quality when paired with appropriate cutting data.

Mounting, compatibility and practical system setup

ISO conformity means the insert integrates into standard ISO holders when the form, relief angle, tolerance class, fastening method, size and thickness are matched. The CPMT09T308 features a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping and simple replacement. The plate thickness of 3.97 mm and the standard 09 size classify it within widely available holder systems, enabling straightforward retrofitting into existing toolrooms without complex adaptations.

Operational benefits and selection guidance for production

Selecting this grade reduces downtime through longer tool life and stable cutting behaviour; its CVD coating is particularly effective when machining a broad range of steels under stable cutting conditions. When planning inserts, choose a chipbreaker and grade that match the workpiece material and the expected stability of the setup. For mixed-production environments, the combination of toughness and wear resistance in this insert supports predictable performance and repeatable results across batches.

FAQ

What materials is this insert intended for?
The CPMT09T308 Tungaloy insert with grade T9215 is primarily intended for medium steel machining and performs well in continuous to lightly interrupted cuts.

How does the CVD coating affect performance?
The CVD-coated carbide surface of the insert improves wear resistance and helps maintain edge integrity, resulting in longer tool life for the CPMT09T308 during standard turning operations.

What holders are compatible with this insert?
Compatibility depends on matching form, relief angle (11°), tolerance class, clamping method, size (09) and thickness (3.97 mm); the insert fits ISO-indexed turning holders designed for rhombic CPMT plates.

Can this insert be used for interrupted cuts?
Yes—grade T9215 is suitable for continuous cutting and light interruptions; for heavy interruption, consider a grade or geometry optimised specifically for interrupted cuts.

What is the purpose of the cylindrical hole and countersink?
The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and precise seating in the toolholder, facilitating repeatable positioning and quick index changes.
