TNGG 160404 SH725 triangular turning insert (60°, coated carbide) — Tungaloy

TNGG 160404 SH725 is an ISO-standard triangular insert for external and internal turning, designed for variable engagement conditions and small-tool applications.

• ISO-standard triangular insert, 60° geometry
• Coated carbide grade SH725 for stable edges
• 0.4 mm corner radius for fine turning
• Double-sided, cylindrical hole for secure clamping

Consistent performance through geometry and grade

The combination of an ISO-standard triangular form and a defined 60° cutting angle gives reliable chip formation and predictable toolpath behaviour. The coated carbide composition, specified as SH725, is formulated for edge stability and toughness, which is particularly valuable in changing engagement conditions or when using smaller toolholders. This results in longer effective cutting intervals and fewer index changes, supporting continuous production and reduced downtime.

Improved surface finish with a compact corner radius

A 0.4 mm corner radius balances strength and finish: it provides sufficient edge support to resist chipping while enabling close tolerances and fine surface quality in light to moderate turning passes. In combination with the insert’s double-sided design and the integrated chipbreaker, this geometry helps maintain consistent cutting forces, so the workpiece surface texture benefits from reduced vibration and better repeatability.

Secure clamping and system compatibility

The insert features a cylindrical hole for positive seating and stable fixation; its 4.76 mm plate thickness ensures robust support in standard ISO clamping arrangements. Compatibility with a holder is determined by form, relief angle, tolerance class, clamping method, size and thickness, so matching the insert to an appropriate ISO external holder or boring bar is essential for optimal results. The design supports straightforward indexing and reliable seating under repetitive operations.

Application scope and process rationale

Intended primarily for turning, this insert is suitable for both external and internal operations when paired with the correct chipbreaker and holder. The SH725 grade and the insert’s geometry promote productive machining with a focus on process security and repeatable surface quality. Selecting the appropriate chipbreaker and grade in line with workpiece material and operational stability will maximise tool life and reduce overall machining costs.
