SNMG 120404 T9215 indexable turning insert — CVD‑coated carbide, 0.4 mm radius, by Tungaloy

SNMG 120404 T9215 is an ISO‑standard indexable insert for turning; designed for external and internal operations in medium steel where high productivity and reliable tool life are required

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• Double-sided chipbreaker for consistent chips
• ISO SNMG geometry with cylindrical hole

Productivity optimised for medium steel turning

The CVD‑coated T9215 grade combines high wear resistance with robust fracture behaviour to extend tool life under continuous to slightly interrupted cuts. As a CVD-coated carbide solution, this insert improves process stability at elevated cutting speeds, which reduces tool change frequency and lowers the cost per component. The balanced performance profile is particularly advantageous for medium steel applications, where productivity and consistent surface quality must be maintained across batch runs.

Consistent geometry for secure clamping and repeatable results

Built to the ISO SNMG form, the square plate with a 0.4 mm corner radius and 90° approach angle ensures predictable engagement and repeatable positioning in compatible holders. The plate’s 4.76 mm thickness and 12 mm size contribute to rigidity, while the cylindrical hole permits secure fastening with common clamping systems. Compatibility depends on form, relief angle, tolerance class, fastening type, size and thickness; this standardised geometry reduces setup time and simplifies tool management across different machines.

Controlled chip formation and straightforward application choice

The double-sided chipbreaker is engineered to produce manageable chips when machining medium steel, improving surface finish and reducing the risk of recutting. Selection of the chipbreaker and the cutting grade should be matched to the workpiece material and the cutting conditions — stability of the setup and the nature of the cut (continuous vs interrupted) determine the optimum combination. The insert is intended for use with a complete system comprising an indexable insert, a matching external holder or boring bar, a shim/clamping kit and replacement screws to secure reliable performance in production environments.

FAQ

Which materials is this grade best suited to?
The SNMG120404 T9215 indexable insert is optimised for medium steel machining; the CVD‑coated carbide grade T9215 combines wear resistance and toughness for productive turning of steel materials.

Can the insert be used for interrupted cuts?
Yes; the T9215 grade is suitable for continuous to slightly interrupted cuts, though the degree of interruption and the rigidity of the setup should guide the final application choice.

What clamping components are required for use?
Use an ISO‑compatible SNMG external holder or boring bar together with a suitable shim/clamping kit and replacement screws to secure the SNMG120404 insert reliably.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius improves edge strength and contributes to stable cutting forces, promoting better surface finish and longer tool life in standard turning operations.

What are the main advantages of the T9215 coating?
The CVD coating of the T9215 grade increases wear resistance while maintaining fracture safety, enabling higher productivity and consistent results on medium steel workpieces.
