SNGN120716 TZ120 — SNGN indexable turning insert for Turning, Tungaloy

The SNGN120716 TZ120 is an ISO-standard indexable turning insert designed for external and internal turning, combining a balanced carbide grade with a square geometry for stable cutting in general turning operations.

• ISO SNGN geometry, 90° cutting angle
• TZ120 Tungaloy grade for wear resistance
• 1.6 mm corner radius for robust cuts
• Square insert 12 mm, thickness 7.94 mm

Consistent production through a wear‑resistant grade

The insert uses the TZ120 Tungaloy grade in a hard carbide base, developed to balance wear resistance and toughness for extended tool life. As an ISO indexable insert, the geometry and tolerance align with standard SNGN seats, which simplifies toolholder selection and tool changeovers. This combination reduces unscheduled downtime and contributes to a predictable production rhythm, making the solution particularly suitable where repeatable machining quality and cycle-time stability are required.

Stable cutting and predictable edge behaviour

With a 1.6 mm corner radius and a square SNGN profile, the design delivers improved edge support and reduced vibration during engagement. The 0° clearance improves contact geometry for axial operations, while the insert thickness of 7.94 mm and a nominal size of 12 mm ensure a robust cutting edge that tolerates higher feed rates without premature chipping. These characteristics translate into fewer insert changes and a more consistent surface finish on turned components.

Seamless integration into ISO tool systems

Compatibility is determined by form, clearance angle, tolerance class, fastening style, size and thickness; the insert is intended to be used with a matching external holder or boring bar, a suitable shim/clamp set and replacement screws as required. As an indexable plate without a central hole and without a chipbreaker, the insert is best paired with holders designed for secure clamp fixation and with a chip control strategy adapted to the workpiece material and process stability. The modular nature of the system supports flexible tooling layouts and straightforward inventory management.

Economic machining through balanced properties

The carbide grade and geometry of this plate offer a pragmatic balance between cost-efficiency and performance: sufficient toughness to resist edge breakage while maintaining resistance to abrasive wear. For many turning operations, this yields lower overall tooling costs per component by extending edge life and preserving dimensional accuracy over longer cuts. The pedigree of the material and coating strategy contributes to process reliability, supporting steady productivity in series production and jobbing alike.

FAQ

What materials is this insert suitable for? The TZ120 grade insert is designed for general turning; selection of chipbreaker and grade should be matched to the specific workpiece material when using the SNGN120716 insert.

How is the insert fixed in the holder? The SNGN120716 insert is secured by the holder's clamping system and, where applicable, by the recommended shim/clamp set and replacement screws for a stable assembly.

Is there a chipbreaker on this insert? This insert is supplied without a chipbreaker; chip control must be achieved via appropriate holder geometry and process parameters.

What does the 1.6 mm radius mean for cutting? A 1.6 mm corner radius provides enhanced edge support for heavier cuts, improving stability and reducing the risk of corner chipping during interrupted or roughing passes.

Can the insert be used for internal turning? Yes, the insert is suitable for both external and internal turning when paired with the correct boring bar or internal-holder configuration.
