DNMG150404 T5125 – Tungaloy turning insert, CVD-coated carbide, rhombic 55° for turning

The DNMG150404 T5125 is a CVD-coated cemented carbide turning insert designed for external and internal turning, especially where interrupted cuts and less stable conditions occur.

• CVD-coated carbide grade T5125
• Optimised for cast iron in interrupted cuts
• Rhombic insert, 55° lead angle, 0.4 mm radius
• Double-sided with cylindrical hole, thickness 4.76 mm

Stable cutting in interrupted turning with a tough coating

The CVD-coated T5125 grade combines enhanced toughness with wear resistance, which is particularly beneficial when machining cast iron under interrupted cutting conditions. The coating reduces flank wear while the substrate supports the cutting edge against mechanical shock, resulting in longer tool life and fewer indexings. This balance between hardness and toughness helps maintain consistent cutting forces, which in turn supports stable spindle loads and predictable cycle times.

Reliable fit and fast indexability for ISO systems

Thanks to the ISO-conforming rhombic geometry and standardized form, the insert ensures straightforward compatibility with a wide range of holders when the form, clearance angle, tolerance class, fixing method, size and thickness are matched. The cylindrical hole and double-sided design offer fast and repeatable indexing, reducing machine downtime and simplifying inventory management. For production environments, these factors translate into smoother tool changes and improved process uptime.

Controlled chip formation and repeatable surface quality

The small 0.4 mm nose radius delivers a compromise between cutting-edge strength and surface finish, enabling reliable dimensional control during turning operations. The double-sided chipbreaker configuration supports better chip control in interrupted cuts, reducing the risk of tangling or secondary operations to clear chips. Together with the coating’s wear resistance, this delivers a predictable surface quality and fewer unexpected tool interventions, which benefits both batch production and mixed-series machining.

FAQ

What materials is this insert suitable for? The DNMG150404 T5125 insert is optimised for machining cast iron, especially under interrupted cutting conditions, owing to its tougher CVD-coated cemented carbide grade.

Is the insert indexable and reversible? Yes, the insert is double-sided with a cylindrical hole, allowing indexable reversals to present a fresh cutting edge and extend usable life.

How does the 0.4 mm nose radius affect machining? A 0.4 mm nose radius provides a balance between edge strength and surface finish, offering dimensional stability while maintaining acceptable surface quality during turning.

Which holders are compatible with this ISO insert? Compatibility follows ISO standards for DNMG inserts; the matching holder must correspond in form, clearance angle, tolerance class, fixing method, size and thickness to ensure secure clamping and correct geometry.

Is this grade suitable for finishing passes? The T5125 grade is designed for robust performance in interrupted cuts and less stable conditions; for fine finishing passes, a grade optimised for smooth continuous cuts may provide superior surface finish.
