SNMG120408 T9215 indexable insert for turning by Tungaloy — CVD-coated carbide, 0.8 mm radius

The SNMG120408 T9215 is an ISO-standard quadrilateral indexable insert designed for external and internal turning, offering a balance of high wear resistance and robustness for medium-steel machining.

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• Double-sided chipbreaker for versatility
• ISO-standard SNMG120408 geometry

Consistent productivity through a wear-resistant grade

The CVD-coated T9215 grade combines a wear-focused coating with a tough substrate to deliver sustained wear resistance and fracture resistance during continuous or lightly interrupted cuts. This means longer intervals between indexings and predictable tool life, which in turn supports higher gross material removal rates and lower machining costs per component. Explaining the technical benefit: a CVD coating deposits hard ceramic layers that protect the substrate at the cutting edge, while the carbide core maintains edge strength under load — a combination that increases productivity without compromising process stability.

Fast set-ups and interchangeability with ISO geometry

Designed to the ISO SNMG120408 form, the insert guarantees dimensional interchangeability with compatible external holders and boring bars; compatibility is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness. The quadrilateral outline and central mounting enable straightforward indexing and secure clamping, reducing downtime during tool changes. The ISO-standard design also simplifies inventory management: one geometry supports multiple applications when paired with the correct holder and chipbreaker.

Practical guidance for application and surface quality

With a 0.8 mm corner radius the insert offers a compromise between edge strength and surface finish: larger radii increase edge robustness and are preferable for heavier cuts, while the given radius still permits good surface finish in finishing passes. The double-sided chipbreaker provides two cutting edges per side, extending usable life and offering versatility across roughing and semi-finishing. Typical use is turning of medium steels; select the chipbreaker and cutting data to match workpiece stability and the intended surface requirement. Note the insert is supplied with cylindrical hole for standard clamping systems.

FAQ

Which holders are compatible with this insert?
Compatibility is determined by the SNMG120408 form; the SNMG120408 T9215 insert fits holders and boring bars designed for SNMG inserts with the corresponding size, thickness and clamping style.

Is this insert suitable for heavy interrupted cuts?
The T9215 grade is designed for medium-steel machining and offers good fracture resistance; it is best for continuous to lightly interrupted cuts rather than heavy interrupted interruptions.

How does the CVD coating affect performance?
The CVD coating on the SNMG120408 T9215 provides a hard protective layer that improves wear resistance and helps maintain edge geometry over longer operating periods.

How many usable edges does the insert offer?
The double-sided design of the SNMG120408 insert provides multiple cutting edges; consult the holder and mounting practice to ensure correct indexing and full use of available edges.

What finish can be expected on medium steel?
When used with appropriate cutting parameters and a suitable chipbreaker, the SNMG120408 T9215 delivers consistent surface quality compatible with semi-finish and finish turning operations.
