SNMG 120412 T9215 Wendeplatten - Tungaloy

High wear resistance from the CVD-coated T9215 grade and a 1.2 mm corner radius deliver sustained productivity in medium steel turning, while the double-sided ISO SNMG120412 form reduces cost per cutting edge; order the insert directly via Metav Werkzeuge or consult their technical team for assistance.

SNMG120412 T9215 ISO indexable turning insert for medium steel turning, CVD-coated, double-sided (Tungaloy)

The SNMG120412 T9215 is an ISO-standard indexable turning insert designed for medium steel applications, combining CVD-coated carbide toughness with a secure cylindrical-hole mounting for reliable clamping.

• CVD-coated carbide for enhanced wear resistance
• Optimised for medium steel turning operations
• Double-sided insert with cylindrical hole
• ISO SNMG120412 form, 1.2 mm corner radius

Greater throughput through durable cutting material

The CVD-coated carbide grade T9215 is engineered to balance wear resistance and fracture toughness, which translates into longer intervals between edge changes and fewer unscheduled tool swaps. In continuous or light interrupted turning of medium steel the coating reduces flank wear, so process stability is increased and cycle times remain consistent. The robust material combination supports higher cutting speeds and steady surface finish, enabling a measurable uplift in productivity and predictable component quality.

Consistent clamping and geometry for repeatable results

Thanks to the ISO-standard SNMG120412 form and the cylindrical hole arrangement, secure fixation and repeatable positioning on compatible toolholders are ensured. The 0° relief angle and the *90° form geometry provide a reliable cutting orientation for external and internal turning operations, while the double-sided design extends the available edge life before indexing. Compatibility with the holder depends on form, clearance angle, tolerance class, attachment, size and thickness, which allows integration into standard turning systems without bespoke tooling changes.

Simplified process planning and chip control for stable production

The insert is supplied with a doublesided chipbreaker and a 1.2 mm corner radius that help to moderate cutting forces and improve chip control during medium steel machining. For practical set-ups the system comprises the insert, an appropriate external holder or boring bar, a backing pad/clamp kit and replacement screws; this modular approach makes tool change straightforward and reduces downtime. Selecting the correct chipbreaker and grade for the workpiece and cutting conditions supports process stability and repeatable surface quality across production runs.

FAQ

Which materials is this insert suited for? The Tungaloy SNMG120412 T9215 insert is optimised for medium steel machining and performs well in continuous to slightly interrupted cuts thanks to the CVD-coated T9215 grade.

Is the insert reversible and how does that affect cost-efficiency? The double-sided geometry of the SNMG120412 reduces cost per cutting edge by extending usable edge life before indexing, contributing to lower tooling costs over production cycles.

Which holders are compatible with this ISO insert? Compatibility with the SNMG120412 form is determined by holder form, clearance angle, tolerance class, attachment, size and thickness; standard ISO SNMG external holders and boring bars designed for SNMG inserts are appropriate.

Can this insert handle interrupted cuts or roughing operations? This grade and geometry are suitable for continuous and light interrupted cuts in medium steel; for heavy interruptions, a different grade or tool layout should be considered.

How is the insert secured in the holder? The SNMG120412 insert uses a cylindrical hole and is clamped with the appropriate backing pad/clamp set and screw; the complete system includes the insert, a matching holder or boring bar, and replacement screws.
