DNMG150404 T505 – Indexable turning insert for turning

The DNMG150404 T505 is a rhombic, ISO‑compliant indexable insert designed for external and internal turning, especially suited to economical machining of cast iron.

• ISO‑compliant rhombic insert
• CVD‑coated carbide for cast iron
• Double‑sided chipbreaker
• Cylindrical hole for secure clamping

Consistent results through stable cutting geometry

The rhombic geometry with a 55° lead angle and 0.4 mm nose radius delivers a balance between strength and accessibility, enabling reliable finishing and medium‑machining passes. The CVD‑coated carbide substrate provides wear resistance at elevated cutting temperatures, which supports longer tool life and reduced changeover frequency. For production environments where repeatability matters, this geometry reduces vibration and maintains a uniform surface quality on grey and nodular cast iron components.

Economical machining and process reliability

The T505 grade combines a wear‑resistant coating with a carbide base to keep running costs low while retaining cutting edge stability. The double‑sided chipbreaker promotes predictable chip formation and evacuation, decreasing interruption from built‑up edge and lowering the risk of workpiece damage. Together, these characteristics enhance machining productivity and help to secure process windows where both power and finish are critical.

Compatibility and secure clamping for shopfloor use

As an ISO‑compliant insert with a cylindrical hole, compatibility with a wide range of indexable holders is defined by form, clearance angle and tolerance class; this facilitates fast integration into existing tool sets. The 4.76 mm thickness offers a robust seating surface and the through‑hole permits firm clamping for higher stability in interrupted cuts. Selection of a suitable holder and clamping kit ensures the full benefits of the insert’s design, especially when machining cast iron with variable stability.

FAQ

What materials is this insert suitable for?
The DNMG150404 T505 Tungaloy insert is optimised for machining cast iron; the T505 grade and CVD‑coated carbide offer wear resistance and stable cutting behaviour on grey and nodular cast iron.

How does the chipbreaker affect performance?
The double‑sided chipbreaker on this indexable insert promotes controlled chip formation and evacuation, which improves surface finish and reduces interruptions during turning with the DNMG150404 T505 Tungaloy insert (SKU 6831258-Tungaloy).

Is the insert compatible with standard ISO holders?
Yes. As an ISO‑compliant insert with a cylindrical hole, the DNMG150404 fits holders and boring bars specified for this ISO designation; compatibility is determined by form, clearance angle and tolerance class.

What does the 0.4 mm nose radius mean for the finish?
A 0.4 mm nose radius balances edge strength and surface quality, enabling consistent finishes on cast‑iron components while maintaining robustness for common turning operations.

Which features help in interrupted cuts?
The combination of carbide material, CVD coating and the cylindrical hole for secure clamping increases stability in interrupted cuts; the insert’s thickness and rhombic geometry also contribute to repeatable, reliable performance.
