TNMG160404 T5125 turning insert by Tungaloy — triangular 60° insert for turning

The TNMG160404 T5125 is an ISO‑standard triangular turning insert designed for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• ISO‑standard TNMG160404 geometry
• CVD‑coated carbide grade T5125
• Double‑sided chipbreaker for stability
• Suited to cast iron and interrupted cuts

Consistent cutting performance under interrupted conditions

The combination of a CVD‑coated carbide substrate and the T5125 grade provides a balance between toughness and wear resistance that is especially valuable for interrupted turning operations. The coating reduces abrasive wear while the tougher substrate contributes to edge stability when cuts are discontinuous, so lengthier tool life and fewer indexing cycles can be expected. This yields improved process efficiency and reduced tooling-related downtime in series and jobbing work.

Straightforward holder compatibility reduces setup time

As an ISO‑standard insert, compatibility with suitable holders is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The insert’s 60° triangular shape, 16 mm size and 4.76 mm thickness mean straightforward selection of compatible external holders or boring bars, and the 0° clearance specification clarifies seating and relief requirements. Clear dimensional standards simplify inventory and lower setup times during tool changeovers.

Material and chip control that protect the cutting edge

The grade is formulated as a tough carbide variant with a CVD coating, making it particularly resistant to the chipping and flank wear often encountered with cast iron and unstable clamping. The double‑sided chipbreaker design promotes predictable chip formation and evacuation, which reduces heat concentration at the cutting edge and supports consistent surface finish. As a result, component quality remains stable across batches and tool costs are better amortised.

System approach and recommended use for reliable results

The insert works as part of a complete system comprising the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. Select the doppelseitig chipbreaker variant and the T5125 grade when machining cast iron or when interrupted cuts are likely; for higher stability and continuous finishing cuts consider alternative chipbreakers or grades. Simple system planning and correct selection of holder and clamp lead to fewer stoppages and reproducible machining outcomes.

FAQ

What materials is this insert suited for? The TNMG160404 T5125 insert is intended primarily for machining cast iron, and its tough carbide formulation and CVD coating make it suitable where interrupted cuts and less stable conditions occur.

How does the T5125 grade affect performance? T5125 denotes a tough, CVD‑coated carbide grade designed to resist chipping and provide stable cutting in interrupted operations; it balances wear resistance and edge strength for reliable production.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, tolerance class, fixing method, size and thickness; the ISO‑standard TNMG160404 geometry allows selection of matching external holders or boring bars that accept 16 mm triangular inserts.

Is the insert designed for external and internal turning? Yes — the insert is suitable for both external and internal turning applications when paired with the appropriate holder and clamping components.

What chip control can be expected during interrupted cuts? The double‑sided chipbreaker promotes stable chip formation and evacuation, which reduces heat at the cutting edge and helps maintain consistent surface quality during interrupted machining.
