CNMG 120412 T9215 — Tungaloy indexable insert for turning (ISO CNMG120412)

CNMG120412 T9215 is an ISO-standard indexable insert designed for turning applications on medium steel, offering a balance of wear resistance and fracture toughness in continuous to slightly interrupted cuts

• ISO CNMG 120412 geometry, 80° rhombic
• CVD-coated carbide grade T9215 for medium steel
• 1.2 mm corner radius for consistent surface finish
• Double-sided chipbreaker with cylindrical hole

Consistent productivity through engineered carbide and coating

The insert combines a CVD-coated finish with a specialised carbide substrate to deliver extended tool life under industrial cutting conditions. The T9215 grade is formulated as a first-choice solution for medium steel machining, pairing high wear resistance with controlled toughness so that the insert performs reliably in continuous and slightly interrupted cuts. This translates into fewer tool changes and a more predictable production rhythm, improving cycle time without sacrificing surface quality.

Geometry that supports accuracy and surface quality

The 80° rhombic geometry and a 1.2 mm corner radius provide a balance between strength and finish. The rhombic shape enables effective clearance and positional stability in standard CNMG toolholders, while the corner radius helps to distribute cutting forces and reduce vibration. A plate thickness of 4.76 mm and the centred cylindrical hole ensure secure clamping and repeatable seating in the tool assembly, which together assist in maintaining dimensional consistency across runs.

Clear system compatibility and straightforward integration

As an ISO-standard indexable insert, compatibility with the toolholder is defined by shape, relief angle, tolerance class, fastening method, size and thickness. The insert’s 0° relief angle and standard sizing make it compatible with a wide range of CNMG-capable holders and boring bars; using the correct underlay shim, clamp set and replacement screws completes the assembly. Specifying holders and clamping components that match the insert’s form and tolerance class reduces set-up time and avoids alignment issues.

Select the right chipbreaker and operating window

The double-sided chipbreaker design supports flexible cutting strategies: select the chipbreaker and grade to match workpiece stability and feeding conditions. For medium steel in a stable set-up, the T9215 grade permits higher metal removal rates with controlled wear. Where interruptions occur or rigidity is limited, reduce feed or select alternative chip control to avoid edge chipping. For best results, pair the insert with a holder that offers sufficient rigidity and consider coolant strategies appropriate for the workpiece and machine.

FAQ

What materials is this insert intended for? The CNMG120412 T9215 insert is intended primarily for medium steel machining and is formulated to combine wear resistance with fracture toughness for continuous to slightly interrupted cuts.

How does the T9215 coating affect performance? The CVD coating of the T9215 grade improves wear resistance and supports higher productivity under stable cutting conditions when used with the correct chipbreaker and holder.

Is the insert interchangeable with other CNMG holders? Yes. The ISO CNMG 120412 geometry, the 0° relief angle and standard plate dimensions mean the insert is compatible with holders designed for CNMG inserts, provided form and tolerance class match.

What benefits does the 1.2 mm corner radius provide? A 1.2 mm corner radius balances edge strength and surface finish, helping to reduce vibration and distribute cutting forces for more consistent part geometry.

Can the insert be used for interrupted cuts? The CNMG120412 T9215 performs best in continuous to slightly interrupted cuts; for heavily interrupted conditions, consider reducing feed or choosing a grade and chipbreaker optimised for greater impact resistance.
