SNMG120412 T9215 ISO Turning Insert by Tungaloy (CVD-coated carbide, 1.2 mm radius)

SNMG120412 T9215 is an indexable turning insert designed for external and internal turning of medium-range steels; square 90° geometry and a double-sided chipbreaker offer a balance of precision and durability.

• CVD-coated carbide grade T9215 for mid-range steel
• 1.2 mm nose radius for precision and roughing
• Square SNMG form, 90° for external and internal turning
• Double-sided chipbreaker with cylindrical hole for clamping

Greater productivity through wear-resistant coating and grade

The SNMG120412 T9215 insert combines a CVD-coated surface with a wear-resistant carbide substrate to deliver extended tool life under typical shop conditions. The T9215 grade is optimised for the machining of medium-strength steel, offering a compromise between high wear resistance and toughness; this translates into fewer indexings and longer production runs. By reducing unplanned tool changes, the insert contributes directly to higher throughput and lower per-part machining costs, which is particularly relevant for batch production and continuous turning operations.

Reliable geometry and chip control for consistent surfaces

The square SNMG form and 90° cutting geometry provide robust support and a predictable cutting edge, while the 1.2 mm nose radius allows a mix of finishing and light roughing without frequent tool swaps. The double-sided chipbreaker improves chip formation and evacuation, reducing the risk of built-up edge and surface damage. The presence of a cylindrical hole ensures secure clamping in compatible holders, so stability at the cutting zone is maintained and dimensional repeatability is improved for turned components.

Clear integration guidance and selection logic for holders

Compatibility with toolholders depends on form, clearance angle, tolerance class, fixing method, size and thickness; select a matching ISO external holder or boring bar and the appropriate underlay/clamping set. The insert is indexable, offering two usable faces and straightforward re-indexing to restore cutting performance. The ISO system approach simplifies inventory: a standard SNMG insert, the correct holder and spare screws make up the system build, enabling rapid replacement and predictable performance. For medium steels and mixed production, choosing the T9215 grade helps balance surface quality with tool life under continuous to slightly interrupted cutting conditions.

FAQ

Which materials are best machined with this insert?
The SNMG120412 T9215 insert is optimised for medium-strength steel; the CVD-coated carbide T9215 grade provides wear resistance suitable for continuous to slightly interrupted turning of steel.

Is this indexable insert suitable for both external and internal turning?
Yes, the square SNMG geometry and 90° cutting angle permit use in both external and internal turning applications when paired with the appropriate holder.

How does the chipbreaker affect machining?
The double-sided chipbreaker improves chip control and evacuation, leading to more consistent surface finish and reduced risk of built-up edge during typical turning operations.

What determines holder compatibility for this ISO insert?
Compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness; matching the insert to an ISO external holder or boring bar and correct clamping parts ensures stable performance.

Can the insert be re-indexed to extend life?
The SNMG form is double-sided and indexable, allowing the use of multiple cutting edges to extend service life and reduce tooling costs.
