DNMG150412 T5125 ISO turning insert for turning applications — Tungaloy, CVD-coated cemented carbide

A DNMG150412 T5125 indexable insert engineered for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade for enhanced toughness
• Rhombic ISO shape with 55° effective cutting angle
• Double-sided chipbreaker design for stable chips
• Compatible with cylindrical-hole clamping systems

Increase machining uptime with a tougher cutting grade

The CVD-coated cemented carbide composition of this insert delivers improved toughness compared with uncoated grades, making it particularly suitable for interrupted cuts and variable clamping conditions. The harder coating layer resists flank wear while the substrate absorbs impact; together they reduce the frequency of tool changes and support a more consistent production flow. This results in measurable gains in productivity and less unscheduled downtime.

Reliable chip control for improved surface finish

Equipped with a double-sided chipbreaker, the insert promotes controlled chip formation even when machining cast iron under unstable conditions. Stable chip flow reduces the risk of re-cutting and burr formation, which helps achieve a better surface finish and lowers downstream finishing effort. The combination of chip geometry and the 1.2 mm corner radius balances edge strength with the ability to maintain dimensional tolerances over longer running periods.

Geometry and mounting designed for predictable compatibility

Designed to the ISO series, the rhombic geometry with a 55° cutting angle and 0° clearance angle ensures predictable behaviour across standard holders. Compatibility with the toolholder depends on form, clearance angle, tolerance class, clamping method, size and thickness — the insert’s 4.76 mm thickness and cylindrical hole make it suitable for many external holders and boring bars. Clear specification reduces setup time and simplifies integration into existing tool systems.

Application-led economy and process stability

The T5125 grade is a tougher, CVD-coated option selected for machining cast iron where interruptions or less rigid setups occur. Its double-sided design doubles indexable life per insert, offering cost-efficiency across medium to long production runs. Specifying this insert supports stable cutting performance, lowers per-part tooling cost and contributes to repeatable results in batch production.
