TNMG 160404 T5125 – ISO turning insert, 60° triangular by Tungaloy

A durable ISO-standard TNMG160404 T5125 indexable insert engineered for turning, optimised for interrupted cuts in cast iron and less stable machining conditions.

• CVD-coated carbide grade T5125
• Optimised for interrupted cuts in cast iron
• Triangular 60° form with 0.4 mm radius
• Double-sided chipbreaker, cylindrical hole for clamping

Robust grade for demanding cast-iron turning

The combination of a CVD-coated surface and a tough carbide substrate gives a balanced performance when machining cast iron under interrupted cutting conditions. The T5125 grade is formulated to resist chipping and maintain cutting-edge integrity where stability is limited, which reduces unplanned tool changes and contributes to a steadier production flow. This section explains why the coating and substrate matter and how they translate into longer effective life for the insert.

Geometry and clamping that support consistent results

A 60° triangular shape and a 0.4 mm corner radius deliver a compromise between edge strength and form-holding for turning. The plate thickness of 4.76 mm and a standard 16 mm size provide structural rigidity, while the cylindrical hole ensures secure clamping in compatible holders. The double-sided chipbreaker improves chip control and allows economical re‑indexing; together, these features reduce vibration and help achieve repeatable dimensional accuracy during external and internal turning.

Practical selection and system compatibility for reliable productivity

Compatibility with the holder is governed by form, clearance, tolerance class, fastening, size and thickness, so the insert must be matched to the toolholder and clamping system for optimum performance. The ISO standard designation simplifies selection inside a modular system: choose the appropriate chipbreaker and holder stiffness to suit the workpiece and cutting conditions. For set-ups that alternate between heavy interruptions and more stable cuts, this indexable insert provides a pragmatic compromise between robustness and surface quality.

FAQ

Which materials is this insert best suited for?

The TNMG160404 T5125 insert (Tungaloy, SKU TUN6853015) is optimised for cast iron, particularly where interrupted cuts or reduced rigidity demand a tougher grade.

How does the 60° triangular geometry affect cutting performance?

A 60° triangular form concentrates strength at the corner, and the 0.4 mm radius on the TNMG160404 balances edge robustness with the ability to produce acceptable surface quality under varying conditions.

Is the insert reversible and how does the chipbreaker help?

The double-sided chipbreaker allows re-indexing of the cutting edge to extend tool life; the design also improves chip control for safer evacuation and reduced risk of built-up edge.

What determines whether this insert fits a specific holder?

Compatibility is defined by form, clearance (free) angle, tolerance class, fastening method, size and thickness; confirm these parameters to ensure correct seating and clamping of the TNMG160404 insert.

Is this grade suitable for finishing operations?

T5125 is a tougher, CVD-coated grade tailored for interrupted cuts and less stable conditions; for high-precision finishing on stable set-ups, a finer-grain or different-coated grade may be preferable.
