CCMT120404 T9225 ISO turning insert — CVD‑coated carbide for turning (Tungaloy)

The CCMT120404 T9225 is an ISO‑standard turning insert designed for external and internal turning of steel, offering a robust universal grade for interrupted and varying engagement conditions.

• CVD-coated carbide grade T9225
• Robust universal for medium–heavy steel
• Rhombic CCMT 80° geometry
• Single-sided chipbreaker, cylindrical hole

Reliable cutting performance for demanding steel turning

The insert is engineered to deliver consistent cutting under variable conditions. The CVD-coated carbide matrix provides a hard, wear‑resistant surface while maintaining a core toughness that reduces edge chipping during intermittent cuts. This combination leads to improved tool life and more predictable dressing cycles in medium to heavy machining operations. The technical choice of coating and substrate yields lower flank wear rates at typical turning speeds, which translates into fewer insert changes and better overall shop throughput.

Controlled chip formation reduces rework and downtime

A single-sided chipbreaker tailored to the insert geometry ensures reliable chip control across a range of feeds and depths of cut. The chip former promotes short, manageable chips in continuous cuts while offering the resilience needed for stops and starts, minimising the risk of tangling or surface damage. For shops handling mixed batches or unstable clamping, this feature supports safer operation, less manual cleaning, and consistent part quality without extensive parameter fine‑tuning.

ISO compatibility and secure mounting for production environments

Designed as an ISO-standard CCMT insert, the component fits into conventional holders when form, relief angle, tolerance class, fastening method, size and thickness match. The rhombic shape with 80° geometry, 0.4 mm radius, and 4.76 mm thickness is suitable for a wide range of external and internal turning setups. A cylindrical hole with a single‑side countersink (40°–60°) ensures positive seating and repeatable clamp force, reducing micro‑movement during heavy cuts and enabling consistent surface finish across production runs.

Practical benefits for workshop productivity and process security

Using a robust universal grade such as T9225 simplifies tooling decisions for mixed steel workloads: fewer grade changes, predictable wear behaviour and good resistance to shock. The insert’s balance of hardness and toughness supports reliable chip control and dimensional stability, making it a cost‑efficient option when labour time and machine uptime are priorities. The result is a more productive process with less interruption, helping to meet delivery windows and maintain part quality in serial production.
