CNMG120408 T9215 CNMG Turning Insert – CVD-coated carbide, rhombic 80° | Tungaloy

CNMG120408 T9215 — a precision ISO turning insert for external and internal turning of medium steels, designed for productive machining with a double-sided chipbreaker and a 0.8 mm corner radius

• CVD-coated carbide grade T9215
• ISO CNMG120408 rhombic insert
• Double-sided chipbreaker for stable chips
• 0.8 mm corner radius, cylindrical hole

Increased productivity for medium-steel turning

The CVD-coated carbide grade T9215 delivers a balance of high wear resistance and fracture toughness, making it particularly suited to productive turning of medium steels under continuous to lightly interrupted cuts. The coating reduces flank and crater wear, which extends tool life and supports consistent surface quality during longer runs. This performance translates into fewer tool changes and higher uptime on the lathe, improving overall process efficiency.

Reliable fit and simple integration into ISO tool systems

This ISO rhombic insert follows the CNMG120408 geometry, so compatibility with holders depends on the insert’s form, relief angle, tolerance class, mounting, size and thickness. The plate’s rhombic shape, 0° clearance angle, 4.76 mm thickness and cylindrical hole ensure secure clamping in standard CNMG toolholders. When paired with the appropriate external holder, anti-rotation support and clamp set, the system provides repeatable positioning and cutting stability, reducing set-up time and variance between operations.

Consistent chip control and application advice

The double-sided chipbreaker and 0.8 mm corner radius provide controlled chip formation and a useful compromise between edge strength and finishing capability. This geometry is effective for both external and inner contours where medium-depth cuts and uninterrupted feeds are common. For applications with light interruptions or when increased edge strength is required, selecting the correct chipbreaker style and the T9215 grade will deliver reliable performance and predictable tool life, supporting cost-effective machining cycles.

FAQ

What materials is this insert best suited for?
The CNMG120408 T9215 insert from Tungaloy is optimised for medium steels, offering a good balance of wear resistance and fracture toughness for continuous and lightly interrupted turning.

Can the insert be used for both external and internal turning?
Yes. The rhombic CNMG geometry and the double-sided chipbreaker make the insert suitable for both external and internal turning operations.

How should a compatible toolholder be selected?
Select a holder that matches the CNMG120408 geometry in form, relief angle, tolerance class, mounting method, size and thickness to ensure correct seating and secure clamping of the insert.

What chip control can be expected from this grade?
The double-sided chipbreaker on the T9215 insert promotes stable chip formation in medium-steel turning, improving process consistency and surface finish.

Is the coating type important for productivity?
Yes. The CVD coating on the T9215 grade enhances wear resistance and helps maintain cutting-edge integrity under productive cutting conditions.
