SNMG 120404 T9215 Turning insert by Tungaloy — CVD-coated carbide, 90° geometry

SNMG120404 T9215 is an ISO-standard turning insert engineered for productive medium-steel machining with a focus on wear resistance and fracture safety

• CVD-coated carbide for wear resistance
• Optimised for medium steel turning
• Double-sided chipbreaker for secure control
• Square form with 90° cutting geometry

Consistent productivity for medium-steel turning

The CVD-coated carbide grade T9215 combines high wear resistance with good toughness, making it particularly suited to continuous and lightly interrupted cuts in medium steel. That combination reduces flank and crater wear, extending tool life and enabling longer uninterrupted runs—this translates into fewer tool changes and improved machine uptime. The insert’s 90° geometry yields predictable engagement and is well suited to standard external and internal turning operations, supporting reproducible process parameters and stable surface quality.

Seamless system fit and secure clamping for straight-forward integration

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening method, size and thickness; the square SNMG120404 form and 4.76 mm thickness match common ISO holders and clamping systems. Using a matching shim and replacement screw as part of the system—insert, compatible holder, shim/clamping set and spare screws—ensures correct seating and repeatable positioning. Defined dimensional data such as the 12 mm inscribed circle and 0.4 mm corner radius support accurate set-up and make it easier to select the appropriate holder for minimal runout and reliable tool life.

Durability and chip control explained for dependable results

The double-sided chipbreaker provides controlled chip formation across typical turning feeds for medium steels, reducing the risk of long, stringy chips and improving surface finish. The CVD coating forms a hard, wear-resistant barrier while retaining a tough substrate beneath, which helps avoid brittle fracture under varying cutting loads. For operations requiring specific chip shapes or interrupted cuts, choosing the correct chipbreaker variant and cutting data will optimise heat distribution and process stability, resulting in consistent part quality and lower overall machining costs.

FAQ

What machining tasks is this insert best suited to?
This insert is designed for turning operations and the T9215 grade is the first choice for medium steel machining, offering a balance of wear resistance and toughness.

How does the CVD coating benefit tool life?
The CVD-coated carbide grade reduces abrasive wear while maintaining a durable substrate, so the SNMG120404 T9215 insert sustains longer cutting intervals and steadier performance under continuous cuts.

Which holders are compatible with this insert?
Compatibility requires matching the insert’s square form, relief angle, tolerance class, fastening method, size and thickness; selecting an ISO-compatible external holder or boring bar that accepts SNMG 12×12 inserts is recommended.

Can the same insert be used for internal and external turning?
Yes, the square geometry and 90° cutting face make the insert suitable for both external and internal turning when paired with the correct holder and clamping components.

What chip control can be expected with the double-sided chipbreaker?
The double-sided chipbreaker is developed to produce short, manageable chips at typical turning feeds for medium steel, improving surface finish and reducing chip entanglement.
