SNMG 120404 T9215 Tungaloy turning insert — CVD-coated carbide, 0.4 mm corner radius

The SNMG 120404 T9215 is an ISO-standard square turning insert engineered for external and internal turning of medium steels, offering a robust CVD-coated cemented carbide grade for continuous to lightly interrupted cutting.

• ISO standard SNMG geometry
• CVD-coated carbide T9215 for wear resistance
• 0.4 mm corner radius for fine surface finish
• Double-sided with cylindrical hole for secure clamping

Consistent productivity for medium-steel turning

The SNMG insert capitalises on the T9215 grade — a CVD-coated carbide developed for mid-range steel applications — to combine elevated wear resistance with reliable fracture toughness. This balance reduces unplanned downtime and supports stable cycle times during continuous or lightly interrupted cutting. The square insert geometry and the 0.4 mm corner radius contribute to consistent surface quality, making the component suitable for both finishing passes and light semi-finishing where tool life and reproducibility matter.

Secure clamping and easy compatibility with ISO holders

Compatibility with a clamping system depends on insert form, clearance angle, tolerance class, fixing method, size and thickness; the SNMG120404 features a cylindrical hole and standard dimensions to match ISO-designated holders and boring bars. Choosing a correctly rated external holder or boring bar with the matching seat and clamping parts ensures the insert’s performance is realised in practice. The indexable design with a central hole and square form enables straightforward indexing, while the insert thickness and tolerance ensure repeatable geometry across replacements.

Improved chip control and process stability

Equipped with a double-sided breaker and the wear-resistant coating of the T9215 grade, the insert supports effective chip formation and evacuation for a broad range of steels. The CVD coating enhances surface hardness and thermal stability, which helps maintain edge integrity under elevated cutting temperatures and higher feed rates. For workshops seeking higher throughput, this tool grade promotes longer periods between tool changes while maintaining dimensional accuracy and surface quality.

Application guidance for reliable results

Select the matching chipbreaker and grade variant based on workpiece material, type of turning (external or internal) and machine/tooling rigidity. The SNMG geometry performs best in stable setups; for interrupted cuts or less rigid operations, opt for increased clamping stiffness and check the suitability of the chipformer. System components typically include the ISO indexable insert, a compatible external holder or boring bar, an underlay/shim or clamp set and matching replacement screws — ensuring a complete, serviceable tooling solution for production environments.
