SNMG 120404 T9215 square turning insert, CVD‑coated – Tungaloy

The SNMG120404 T9215 is a square, double-sided indexable insert engineered for turning applications in medium steel, offering a robust balance of wear resistance and fracture toughness for continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215
• Double-sided square insert for cost efficiency
• 12 mm size with 0.4 mm corner radius
• Cylindrical hole and 0° relief angle

Delivering sustained productivity through material and coating

The combination of a CVD-coated surface and the T9215 cutting grade provides notable wear resistance while maintaining sufficient toughness to resist edge chipping. For medium-steel turning, this balance translates into longer tool life and predictable performance under sustained use. The coating reduces flank wear and improves thermal stability, which supports higher feed or slightly increased cutting speeds without sacrificing surface integrity. This results in fewer tool changes and more consistent cycle times on production batches.

Secure geometry for reliable clamping and repeatable results

A square 12 mm insert form with a cylindrical hole and defined 0° relief angle ensures stable clamping and precise seating in ISO‑compliant holders. The 4.76 mm thickness contributes to rigidity at the cutting edge, reducing vibration and improving dimensional repeatability. Compatibility with standard holder geometries is determined by form, relief angle, tolerance class, fastening method, size and thickness, which allows this insert to be indexed conveniently and keeps machine downtime to a minimum when re‑setting tools.

Controlled chip formation and improved surface finish

The double-sided chipbreaker geometry combined with a corner radius 0.4 mm supports consistent chip control and helps achieve high-quality surface finishes with reduced risk of built-up edge. A moderate corner radius provides a compromise between strength and fine finish: it increases edge robustness for interrupted cuts while still permitting finer feeds for superior surface results. As a consequence, secondary finishing operations can be reduced, saving time and costs in downstream processes.

Practical integration and economical use in production workflows

As a reversible, double-sided insert, this component offers two usable cutting edges per side, improving cost-efficiency per edge and simplifying inventory management. The insert forms part of an ISO‑based system comprising the insert, a matching external holder or boring bar, a shim/clamp set and spare screws; using standardised components eases procurement and replacement. In production, the combination of indexable insert design and the T9215 grade supports steady throughput with predictable tool-change intervals, making process planning more straightforward.

FAQ

Which holder types are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the SNMG120404 T9215 fits ISO-compatible external holders and boring bars designed for square SNMG inserts.

Is this insert suitable for interrupted cuts?
Yes, the T9215 grade offers a balance of wear resistance and fracture toughness suited to continuous and slightly interrupted cuts in medium steel applications.

How does the corner radius affect machining results?
A 0.4 mm corner radius increases edge strength and helps maintain surface quality; it is a compromise between robustness for interrupted cuts and the ability to achieve fine surface finishes.

How many cutting edges are available per insert?
The double-sided square design provides multiple indexing positions; the exact number of usable cutting edges depends on orientation and wear, enabling economical edge usage.

What materials is the insert best suited for?
This CVD-coated carbide grade is optimised for medium-steel machining and delivers consistent performance when paired with appropriate chipbreaker and cutting parameters.
