• Optimised for medium steel machining
• Double-sided chipbreaker for versatile use
• ISO SNMG 12×12 mm, 0.4 mm radius

Improved throughput through wear-resistant CVD coating

The CVD-coated carbide in this insert delivers a balance of wear resistance and breakage resistance, making it a reliable choice for serial turning work. Grade T9215 is optimised for medium steel, allowing higher cutting speeds and extended tool life in continuous to slightly interrupted cuts. By reducing flank wear and maintaining edge geometry, the insert supports stable dimensions and consistent surface finish, which contributes directly to improved process efficiency and lower per-part tooling cost.

Proven compatibility and system advantages for quick changeovers

Designed as part of an ISO system, the insert fits into established toolholders when form, relief angle, tolerance class, fastening, size and thickness are matched. The system comprises the ISO indexable insert, a suitable external holder or boring bar, a shim/clamp set and replacement screws. This structured approach ensures repeatable seating, straightforward indexing and reduced setup times, which is particularly advantageous in batch production and mixed-series machining where tool changes must be predictable and fast.

Geometry that enhances stability and cutting predictability

Square plate geometry with a 12 mm inscribed size and 4.76 mm thickness provides a sturdy cutting edge and good support in the seat. The 0.4 mm corner radius gives a balance between edge strength and finish quality, while the 0° relief angle provides a neutral seating position for many turning tasks. A cylindrical hole secures the insert reliably in the clamp; the double-sided chipbreaker design allows two usable cutting positions per side, extending service life before indexing. These features together ensure predictable chip control and repeatable results on medium steel components.

Practical selection advice and lifecycle considerations

Select the chipbreaker and grade to match workpiece material, cutting conditions and machine stability — for the present grade that means prioritising medium steel programmes and steady feeds. Regular inspection for flank wear and micro-chipping preserves component quality; the insert’s double-sided design and CVD coating support multiple indexings to maximise service life.

FAQ

Which materials is this insert best suited for?
The SNMG120404 T9215 indexable turning insert from Tungaloy (SKU 6796042-Tungaloy) is optimised for medium steel and performs well in continuous to slightly interrupted turning operations thanks to its CVD-coated carbide composition.

How does the T9215 coating improve cutting performance?
The CVD-coated T9215 grade on the SNMG120404 improves wear resistance and edge stability, enabling longer tool life and more consistent surface finishes under demanding production conditions.

Is the insert compatible with standard ISO SNMG holders?
Yes — the SNMG120404 follows ISO plate geometry; compatibility requires matching the holder by form, relief angle, tolerance class, fastening method, size and thickness to ensure correct seating and clamping.

What are the key geometric specifications of the insert?
The SNMG120404 insert is square with a 12 mm inscribed size, 4.76 mm thickness, a 0.4 mm corner radius, a 0° relief angle and a 90° included angle; it features a cylindrical hole for secure clamping.

When should the insert be indexed or replaced?
Indexing or replacement of the SNMG120404 is recommended when measurable flank wear or chipping affects dimensional accuracy or surface quality; the double-sided chipbreaker and CVD coating allow multiple indexings before replacement.
