SNMG 120402 T9215 indexable turning insert — ISO SNMG geometry for turning

SNMG120402 T9215 is an indexable turning insert designed for medium-steel machining, offering a balance of wear resistance and fracture toughness for continuous to lightly interrupted cuts

• ISO SNMG 120402 geometry
• CVD-coated carbide grade T9215
• Double-sided chipbreaker for reliable chips
• Square 12 mm insert, 4.76 mm thickness

Boost throughput with consistent edge life

The CVD-coated carbide grade T9215 combines high wear resistance with fracture resistance, which supports longer tool life under typical production turning conditions. For shops needing steady productivity, this composition reduces downtime for insert changes and maintains cutting performance during continuous and slightly interrupted cuts. The result is fewer interventions at the machine and a more predictable production rhythm, making the grade particularly suited to medium-carbon and alloyed steels where balance between tool life and edge stability is crucial.

Secure fit and predictable geometry for repeatable accuracy

ISO compatibility ensures the insert matches standard clamping systems: form, relief angle, tolerance class, fastening method, size and thickness determine compatibility with the chosen holder. The insert has a 0° clearance angle and a square 12 mm format with 4.76 mm thickness, and is supplied with a cylindrical hole for positive locating and secure fastening. These geometric details translate into reproducible seating and consistent cutting angles across batches, improving dimensional repeatability and reducing set-up variation on external and internal turning operations.

Effective chip control and straightforward application guidance

The double-sided chipbreaker is engineered to control swarf during turning and to be effective across a range of feeds and depths typical for medium-steel work. A corner radius of 0.2 mm provides a good compromise between surface finish and edge strength for semi-finishing and medium turning passes. Selection of the correct chipbreaker and grade for the workpiece and machining stability remains important; when paired with the right holder and cutting parameters, the insert delivers stable cutting, reliable swarf control and consistent surface quality. Metav Werkzeuge can advise on matching insert, holder and cutting data for specific parts and machines.

FAQ

What materials is this insert suited for?
The SNMG120402 T9215 insert is optimised for medium-steel machining, offering a combination of wear resistance and toughness suitable for alloyed and medium-carbon steels.

Is the insert reversible or single-use per edge?
This is a double-sided insert, so both faces can be indexed for a fresh cutting edge, effectively providing multiple usable edges before disposal.

Which holders are compatible with the SNMG120402 geometry?
Compatibility follows ISO SNMG standards; holders that match the SNMG form, relief angle, tolerance class, fastening method, size and thickness will accept the insert reliably.

What surface finish and cutting purpose does a 0.2 mm radius support?
A 0.2 mm corner radius is suitable for semi-finishing and general turning where a compromise between edge strength and surface quality is required, giving stable cutting with good surface results.

Can the insert handle light interruptions in the cut?
Yes. The T9215 grade combines fracture resistance with wear resistance, making it appropriate for continuous to lightly interrupted cutting conditions.
