SNMG 120404 T9215 SNMG turning insert by Tungaloy (CVD-coated carbide, 0.4 mm radius)

SNMG120404 T9215 is an ISO-compliant square turning insert for external and internal turning, designed for productive medium-steel machining

• CVD-coated carbide for long tool life
• Double-sided chipbreaker for reliable chip control
• 0.4 mm corner radius for versatile finishing
• ISO SNMG120404 square insert with cylindrical hole

Extended productivity for medium-steel turning

The CVD-coated carbide grade T9215 is engineered for high wear resistance while preserving fracture toughness, making it a reliable choice for continuous and light interrupted cutting. This combination reduces unplanned tool changes and helps maintain a steady production rhythm, which in turn supports higher throughput and lower per-part tooling costs. Practical benefits include longer intervals between regrinds and more consistent component tolerances, particularly when machining common construction and engineering steels.

Predictable chip control and surface quality

A double-sided chipbreaker integrated into the geometry ensures controlled fragmentation of chips across a range of cutting depths and feed rates, reducing rework and improving swarf evacuation. The 0.4 mm corner radius supports a balance between edge strength and surface finish; small radii reduce cutting forces during finishing passes while still providing sufficient edge support for light interruptions. Together, these features contribute to repeatable surface integrity and reduced downtime for cleaning and chip management.

ISO system compatibility for straightforward integration

The insert follows the ISO SNMG120404 form and is compatible with standard external holders and boring bars when matched by form, relief angle, tolerance class, clamping method, size and thickness. With a 12 mm size and 4.76 mm thickness plus a cylindrical hole for secure fastening, the component integrates into common turning tool systems without the need for bespoke adapters. This makes tool-room planning more predictable and simplifies stocking: the insert can be combined with existing holders, shims and clamping sets to create a robust tooling package.

Application guidance for reliable results

Designed primarily for turning on medium steel, the geometry and grade excel under steady cutting conditions; they are also suitable for light interruptions provided machine and setup rigidity are adequate. For best results, select a holder that minimises overhang and ensures stable clamping, and match feeds and depths to the stability of the setup rather than pushing extremities of the grade. When replacement is required, the double-sided design permits indexing for efficient use of the cutting edges, reducing total tooling consumption and improving cost-efficiency.

FAQ

What holder types are compatible with this SNMG insert?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; the SNMG120404 designation matches standard ISO SNMG holders and boring bars when these parameters align.

Is the T9215 grade suitable for interrupted cuts?
The T9215 CVD-coated grade is optimised for continuous to light interrupted cuts in medium steel, combining wear resistance with edge stability for predictable performance.

How does the double-sided chipbreaker benefit production?
A double-sided chipbreaker provides consistent chip control and allows indexing of unused edges, which extends tool life and reduces handling of sharp swarf during production.

Can this insert be used for internal turning as well as external turning?
Yes; the geometry and mounting hole enable use in both external and internal turning applications provided the corresponding holder and setup are appropriate.

What size and mounting details should be checked before ordering?
Confirm the insert size (12 mm), thickness (4.76 mm), corner radius (0.4 mm), relief angle (0°) and the presence of a cylindrical hole to ensure correct fit with the chosen holder.
