SNMG 120408 T9215 SNMG — Turning insert (Tungaloy)

SNMG120408 T9215 is an ISO-format, square indexable insert designed for external and internal turning applications, offering a robust CVD-coated carbide grade for continuous to slightly interrupted cuts.

• ISO SNMG120408 format, square geometry
• CVD-coated carbide grade T9215
• 0.8 mm corner radius for versatile machining
• Double-sided chipbreaker, with cylindrical hole

Consistent productivity for medium-steel turning

The CVD-coated carbide grade T9215 is engineered for high productivity in medium steel machining, combining elevated wear resistance with good fracture toughness. This balance enables longer tool life under continuous to slightly interrupted cutting conditions, reducing the frequency of index changes and machine downtime. Because the grade resists abrasive wear while maintaining edge stability, cycle times can be optimised without compromising surface quality or dimensional consistency.

Reliable edge control and surface quality

With a double-sided chipbreaker and a defined 0.8 mm corner radius, the insert supports predictable chip formation and stable cutting forces, which improves finishing passes and repeatability. The square form factor and 90° approach angle facilitate robust face and shoulder turning operations, while the cylindrical hole provides secure clamping and alignment in compatible holders. These design features translate into uniform surface finishes and fewer secondary operations.

System compatibility and handling efficiency

As an ISO-standardised insert, compatibility with holders is determined by shape, clearance angle, tolerance class, fastening method, size and thickness. The SNMG120408 format and 4.76 mm thickness work with a wide range of external holders and boring bars, simplifying tool inventory and changeover. Clear identification of the ISO designation 120408 and the manufacturer SKU supports procurement and reordering accuracy within production workflows.

Practical selection guidance and application scope

The T9215 grade is a dependable first choice for general-purpose turning of medium-strength steels where a blend of wear resistance and breakage control is required. For slightly interrupted cuts or applications with variable stability, the insert’s fracture-resistant properties help maintain production continuity. When selecting a chipbreaker or holder, match the insert’s geometry and clearance characteristics to the machining strategy and workpiece clamping to exploit the full benefit of the carbide grade and chip control features.
