CPMT 09T312 T5115 — ISO turning insert for turning applications, CVD-coated carbide, Tungaloy

The CPMT09T312-CM T5115 is an ISO-indexed turning insert engineered for external and internal turning of cast iron components, offering a balance of wear resistance and cutting-edge stability.

• ISO rhombic insert CPMT 09 size
• CVD-coated carbide grade T5115
• Balanced wear resistance and edge stability
• Cylindrical hole with 40°–60° countersink

Consistent performance for cast iron turning

The insert is manufactured from carbide with a CVD coating, delivering a combination of abrasion resistance and thermal stability that suits continuous production. The T5115 grade is a universal choice for cast iron, offering an effective compromise between hardness and edge robustness; this results in longer usable life and reduced tool changes. Because the coating reduces adhesion and improves heat resistance, operators can maintain steady cutting parameters and benefit from reliable component quality even in repetitive turning tasks.

Geometry and chip control that reduce downtime

Designed in a rhombic form with an 80° approach and a 1.2 mm corner radius, the insert promotes stable contact conditions and predictable tool forces. The CM chipbreaker is optimised for chip formation in grey and nodular cast iron, producing controlled, short chips that clear the cutting zone reliably. A cylindrical hole with a 40°–60° one-sided countersink enables secure clamping and repeatable seat positioning, which helps maintain consistent surface finish and reduces the risk of insert slippage — a direct contribution to higher machine uptime and process security.

System compatibility and practical advantages

As an ISO-standardised indexable insert, compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the insert is intended for use with suitable external holders or boring bars together with an appropriate shim/clamping set and replacement screws. The geometry and 3.97 mm plate thickness provide a robust contact area for moderate to heavy cuts, while the universal grade supports both roughing and finishing passes in many cast-iron machining applications. The product is supplied with a clear article identity for traceability and easy stock management in production environments.

FAQ

What materials is this insert suitable for?
The CPMT09T312-CM T5115 insert is optimised for cast iron machining; the T5115 grade and CVD coating balance wear resistance and edge stability for consistent results.

How does the CM chipbreaker affect chip control?
The CM chipbreaker on the Tungaloy turning insert produces short, controllable chips in cast iron, aiding evacuation and reducing the likelihood of chip entanglement in turning operations.

What does the cylindrical hole with countersink provide?
The cylindrical hole with a 40°–60° one-sided countersink ensures secure seating and repeatable clamping for the CPMT09T312-CM insert, improving positional stability during heavy cuts.

Is the insert compatible with standard ISO holders?
The CPMT09T312-CM is ISO-standardised; compatibility requires matching holder form, clearance angle, tolerance class, fastening method, size and thickness to ensure correct seating and performance.
