TNMG160416 T5125 triangular indexable insert for turning — Tungaloy CVD-coated carbide, 60°

The TNMG160416 T5125 is an ISO triangular indexable insert engineered for external and internal turning, particularly where interrupted cuts or less stable clamping demand a tougher grade.

• CVD-coated carbide grade T5125
• Designed for cast iron machining
• Double-sided chipbreaker for chip control
• 60° triangular geometry for versatile turning

Reduced downtime and stable cutting in interrupted turning

The TNMG160416 insert combines a CVD-coated surface with a tougher carbide substrate to resist wear under interrupted cutting, which results in fewer indexings and longer productive runs. This configuration is especially effective for the machining of cast iron, where fluctuation in cutting forces can lead to premature edge damage; by selecting the T5125 grade and the appropriate chipbreaker, the insert provides improved chip control and consistent cutting performance. The net effect is lower tooling change frequency and a steadier production flow.

Predictable edge life and controlled chip evacuation

A double-sided chipbreaker, applied to a triangular geometry, gives multiple usable cutting edges and predictable behaviour in varied conditions, which supports process reliability and cost-efficiency. The ISO format ensures that indexing and regrinding cycles are straightforward, while the CVD-coated surface reduces abrasive wear and helps maintain a stable cutting edge. These attributes make the insert suitable where repeatable surface quality and tool life are priorities, without complex parameter adjustments.

Simple integration: dimensions and mounting that matter

Compatibility with toolholders depends on form, relief, tolerance class, fastening, size and thickness; the key dimensions for this insert are a 1.6 mm corner radius, 4.76 mm plate thickness and a 16 mm inscribed circle, mounted via a cylindrical hole in a 60° triangular layout. These measurable features facilitate straightforward selection of a matching external holder or boring bar and reduce set-up uncertainty. The triangular shape, combined with the double-sided design, optimises the number of indexed edges per insert and contributes to economical machining cycles.

FAQ

Is this insert suitable for machining cast iron?
Yes. The TNMG160416 T5125 insert uses a tougher T5125 carbide grade and a CVD-coated surface, making it suitable for cast iron machining, particularly in interrupted-cut scenarios.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the TNMG160416 promotes consistent chip control and stable cutting behaviour, which aids process reliability and reduces the likelihood of edge damage.

What mounting features must be checked when selecting a holder?
Check form, relief (clearance) angle, tolerance class, fastening method, size (16 mm) and plate thickness (4.76 mm) to ensure the insert fits the chosen holder or boring bar.

How many cutting edges are available before disposal?
The triangular 60° geometry combined with a double-sided design provides multiple indexable edges per insert, extending usable service life and improving cost-efficiency.
