TNGG 160402 SH725 Tungaloy indexable turning insert — triangular 60° geometry

A TNGG160402 SH725 indexable turning insert for ISO‑standard turning, designed for external and internal turning where reliable edge life and quick indexing are required

• TNGG ISO triangular insert, 60° geometry
• SH725 coated carbide for edge stability
• Double-sided chipbreaker for versatility
• Central cylindrical hole for secure clamping

Delivering consistent productivity for turning operations

The 60° triangular geometry combined with a corner radius 0.2 mm provides a balance between cutting strength and fine surface finish, making the insert suitable for both finishing and light to medium roughing tasks. As an indexable insert, the component offers four cutting edges per insert in a compact footprint, which reduces tool changes and keeps cycle times low. The design of the geometry and the standard ISO dimensions also support predictable rigidity and straightforward toolpath programming, resulting in measurable throughput gains on production lathes and CNC turning centres.

Stable cutting edge and reliable chip control for varied conditions

The SH725 grade denotes a coated carbide composition engineered for toughness and stable cutting edges under fluctuating engagement conditions. The double-sided chipbreaker improves chip formation and evacuation, which lowers the risk of built-up edge and helps maintain consistent surface quality. In practice this means longer intervals between indexing, fewer interruptions for clearance, and a steadier process window when machining short runs or mixed batches. The coating enhances wear resistance and contributes to repeatable tool life on small‑scale holders and in operations with variable cut depths.

Secure mounting and compatibility guidance for holder selection

A central cylindrical hole enables positive clamping and simple orientation in compatible ISO turn holders or boring bars. Compatibility with a given toolholder is determined by insert shape, relief angle, tolerance class, fastening method, size and thickness — the insert ships in the ISO series intended for matched holders, underplates and clamping sets. The insert thickness of 4.76 mm and the 16 mm inscribed circle are standard dimensions that ease holder selection. For system integrity, use the specified underlay/klemmsatz and replacement screws that correspond to the holder manufacturer’s clamping specification.
