CNMG120412 T9215 Tungaloy turning insert — CVD-coated carbide, 80° rhombic

CNMG120412 T9215 is an ISO-format turning insert designed for external and internal turning in medium-steel applications, combining high wear resistance with robustness for continuous to slightly interrupted cuts.

• CVD-coated carbide for medium-steel machining
• 80° rhombic form with 1.2 mm corner radius
• Double-sided chipbreaker for versatile cutting
• Cylindrical hole for secure mounting

Greater productivity from a wear-resistant grade

The T9215 grade is a CVD-coated carbide developed for the demands of medium-steel turning, offering a balance of high wear resistance and fracture resistance that supports sustained cutting performance. In continuous and lightly interrupted cuts this grade enables higher material removal rates with consistent tool life, translating into improved productivity and fewer tool changes. For job shops and production lines seeking repeatable output the stable performance of this grade reduces process variability.

Secure seating and dimensional reliability for stable cuts

Compatibility with the clamping system is determined by form, relief angle, tolerance class, fastening, size and thickness; the insert’s 80° rhombic geometry and 1.2 mm radius deliver a favourable mix of edge strength and cutting versatility. The 0° relief angle and 4.76 mm thickness provide reliable support under load, while the cylindrical hole ensures secure, repeatable mounting. These dimensional features help maintain cutting stability and reduce vibration, which benefits surface finish and tool life in batch production.

Practical setup choices to match the workpiece and process

The double-sided chipbreaker offers two cutting edges per face and is suitable for a broad range of feeds; select the chipbreaker and grade according to the workpiece material, cutting mode and machine stability. The complete system typically comprises the ISO insert, an appropriate external holder or boring bar, a shim/clamp set and replacement screws for reliable assembly. Choosing a matched holder and correct clamping torque preserves edge integrity and enables consistent chip control.

Fewer interruptions, lower tooling costs and steadier results

Indexable geometry and dual usable faces reduce tooling expenditure and downtime compared with single-edge solutions, while optimised chip formation supports dependable process cycles. The combination of grade and geometry yields double-sided indexability and stable chip formation, promoting shorter setup times and enhanced process reliability for serial turning operations. The insert is therefore suited to users seeking cost-efficient, repeatable performance on medium steels.

FAQ

What materials is this insert suitable for?
The CNMG120412 T9215 insert from Tungaloy is optimised for medium steel machining and is specified for continuous to slightly interrupted cuts.

How is the insert secured in the holder?
The CNMG120412 T9215 is clamped via a cylindrical hole and must be paired with a matching external holder or boring bar; compatibility depends on form, relief angle, tolerance class, fastening, size and thickness.

Is the insert indexable and how many cutting edges are available?
Yes — the CNMG120412 T9215 is double-sided, providing multiple usable edges for indexable use and cost-effective edge changes.

What is the corner radius and how does it affect performance?
The insert has a 1.2 mm corner radius, which balances edge strength with a capable finish; this radius supports robust cutting and contributes to stable chip formation on medium-steel work.

Can this grade handle interrupted cuts?
The T9215 CVD-coated carbide grade is suitable for continuous to slightly interrupted cuts; for heavier interruptions assess machine stability and select appropriate cutting parameters.
