CCMT 120412 T9215 turning insert by Tungaloy — ISO rhombic insert for turning

The CCMT120412 T9215 is an ISO‑indexable rhombic turning insert designed for external and internal turning, offering a CVD‑coated carbide grade optimised for mid‑range steel machining.

• CVD‑coated grade T9215 for mid‑range steel
• ISO rhombic form CCMT 80° included angle
• 1.2 mm corner radius for robust edge strength
• Cylindrical hole with single‑side countersink 40°–60°

Increased tool life and consistent wear resistance for production shifts

The CVD‑coated carbide in grade T9215 is formulated to combine high wear resistance with good fracture toughness, translating into longer tool life and fewer insert changes during production. The CVD coating provides a hard, wear‑resistant outer layer while the carbide substrate maintains toughness; this balance is particularly beneficial when machining medium‑hard steels under continuous and light interrupted cuts. For operations seeking stable cycle times and predictable consumable behaviour, the combination of coating and substrate reduces flank wear and helps maintain component tolerances over longer intervals.

Secure geometry and straightforward holder compatibility reduce downtime

As an ISO‑indexable turning insert, the component uses standard geometric parameters to ensure predictable seating and clamping. The rhombic 80° included angle and the 1.2 mm corner radius provide a compromise between edge strength and dimensional control, suitable for finishing and general turning tasks. Compatibility with a toolholder depends on form, clearance angle (7°), tolerance class, fixing method, size (12) and thickness (4.76 mm); these parameters ensure correct seating and minimise vibration. The insert’s cylindrical hole with a 40°–60° single‑side countersink enables standard screw clamping with a shim or clamping set, simplifying replacement and reducing fixture‑related downtime.

Application guidance: select chipbreaker and holder for best results

This grade and geometry perform best when the chipbreaker and holder stability match the workpiece material and cutting conditions. The single‑sided chipbreaker supplied is intended for predictable chip formation in steel; for heavily interrupted cuts or unstable set‑ups, a different chip control geometry or a more robust clamping arrangement should be chosen. The system is built around the indexable plate, a compatible external holder or boring bar, a shim/clamping set and the appropriate screw; keeping spare screws and shims on hand supports quick changeovers. Practical selection — matching grade T9215, the chipbreaker style and the holder rigidity — delivers improved surface finish, reduced rework and higher overall productivity.

FAQ

What materials is the CCMT 120412 T9215 best suited for?
The Tungaloy CCMT 120412 T9215 is optimised for mid‑range steel machining and performs well in continuous to light interrupted cuts; select the chipbreaker and holder according to workpiece stability.

How is compatibility with a toolholder determined?
Compatibility is defined by form, clearance angle (7°), tolerance class, fixing method, size (12) and thickness (4.76 mm); verify these parameters on the holder drawing before fitting the insert CCMT120412.

What advantages does the T9215 coating provide?
Grade T9215 is a CVD‑coated carbide developed for a balance of wear resistance and fracture toughness, resulting in extended tool life and reliable performance during production runs.

Can this insert be used for internal turning?
Yes, the CCMT120412 insert is suitable for both external and internal turning when combined with an appropriate boring bar and the correct chipbreaker for the application.

What is the hole and clamping style of the insert?
The insert features a cylindrical hole with a single‑side countersink (40°–60°) for standard screw clamping together with a shim or clamping set.
