SNMG120412 T9215 turning insert by Tungaloy — ISO square insert for medium steel machining

The SNMG120412 T9215 provides an ISO‑standard, square indexable solution designed for external and internal turning in medium steel, combining wear resistance with fracture toughness.

• CVD-coated carbide grade T9215
• Double-sided insert with 1.2 mm radius
• Square 12 mm size, 4.76 mm thickness
• Cylindrical-hole, 90° turning profile

Consistent productivity through wear-resistant grade and geometry

The combination of CVD‑coated carbide and the T9215 grade offers a clear productivity advantage for medium steel applications. The coating enhances surface hardness and heat resistance, while the substrate ensures toughness; together they support longer tool life under continuous to light interrupted cuts. This results in fewer index changes and steady cycle times on production runs, making the insert an efficient choice where repeatable performance is essential.

Stable cutting behaviour and reliable edge security

A 1.2 mm corner radius and a 90° profile deliver stable cutting forces and predictable chip flow. The double-sided design effectively doubles the available cutting edges before reconditioning, and the geometry helps maintain surface finish under moderate feed rates. For machining operations that prioritise dimensional consistency, the combination of radius and edge preparation reduces the risk of edge chipping and contributes to repeatable component accuracy.

ISO compatibility and secure clamping for simple integration

Designed as an ISO‑standard turning insert, the plate fits holders that match form, relief angle, tolerance class, fastening and size. The cylindrical hole with a central bore facilitates secure clamping in standard chucks and cutter bodies, while the 4.76 mm thickness provides robust seat support. This standardisation minimises setup complexity and shortens changeover times when migrating between compatible tools in the same workstation.

Application suitability and selection guidance for medium steel

The insert is optimised for medium steel machining and performs well with continuous and slightly interrupted cuts; selecting an appropriate chipbreaker and adapting cutting parameters to workpiece rigidity will maximise results. For less familiar applications, technical consultation is recommended to align holder choice, feed and speed with the T9215 performance profile and to ensure the chosen chipbreaker matches the material and machining stability.

FAQ

Which materials is this insert intended for?
The SNMG120412 T9215 insert is intended primarily for medium steel machining; the T9215 grade and CVD coating balance wear resistance and toughness for this material class.

How is the insert secured in the toolholder?
Clamping is via the central cylindrical hole; the insert requires a compatible ISO‑type holder with matching form, clearance and fastening to ensure a secure seat.

What advantages does the T9215 grade provide?
Tungaloy’s T9215 grade combines high wear resistance with fracture toughness, supporting higher productivity and reliable edge life in continuous to light interrupted cuts.

Is the insert indexable and reversible?
Yes, the plate is double‑sided and indexable, providing multiple cutting edges before replacement or regrinding is needed.

Which chipbreaker style is fitted to this insert?
The plate features a double‑sided chipbreaker; selection of the most suitable breaker should correspond to the workpiece material and the machining stability required.
