DNMA150604 T515 — DNMA rhombic indexable insert for Turning, Tungaloy

The DNMA150604 T515 is an ISO-standard rhombic indexable insert designed for external and internal turning, optimised for economical cast iron machining.

• CVD-coated carbide for economical cast iron machining
• Rhombic 55° geometry for versatile turning operations
• 0° clearance angle for stable support in interrupted cuts
• Cylindrical hole with screw fixing for secure clamping

Proven geometry and coating for efficient cast iron turning

The insert combines a CVD-coated carbide grade with a rhombic geometry that yields consistent cutting behaviour in cast iron. The 55° lead angle provides a compromise between strength and accessibility, making this configuration suitable for both external facing and internal turning. The T515 coating increases wear resistance and helps maintain edge stability at raised cutting speeds, which translates into improved tool life and lower overall machining costs. For users seeking economical productivity on cast iron components, this geometry and coating pairing is a practical choice.

System readiness and secure clamping for repeatable results

Compatibility with the toolholder depends on form, relief angle, tolerance class, fastening method, size and thickness; the insert is designed for straightforward integration into ISO indexable systems. The 0° relief angle and cylindrical hole ensure a secure interface with a matching screw and clamping set, reducing micro-movement under load and supporting repeatable part quality. Because the insert sits on a standard backing and uses common fastening hardware, maintenance and index changes are rapid, supporting high uptime in production environments.

Practical setup and machining recommendations for stable productivity

When using the DNMA150604 for turning, select a holder and machine parameters that match the workpiece stability and the intended cutting regime. For interrupted cuts or unstable setups, the combination of the rhombic form and the CVD-coated carbide grade helps preserve the cutting edge, but prioritising a rigid clamping arrangement is essential. The insert is supplied without a chipbreaker, so choosing cutting data and feed that promote reliable chip evacuation will aid surface finish and protect the edge. With correct setup the insert supports efficient, repeatable machining cycles and good dimensional control.

FAQ

Which materials is this insert optimised for? The DNMA150604 T515 insert is optimised for the economical machining of cast iron; the T515 grade and rhombic geometry favour wear resistance and stable cutting in such materials.

What holder features are required for correct fit? Correct fit requires a holder matching the rhombic DNMA form, the specified thickness (6.35 mm), the 0° relief angle and a compatible screw/clamp interface for the cylindrical hole.

How does the T515 coating influence performance? The T515 CVD coating improves edge life and wear resistance, allowing higher cutting speeds and more consistent surface quality compared with uncoated grades.

Is a chipbreaker integrated in this geometry? No; the insert is supplied without a chipbreaker. Chip control must be achieved through cutting data, tool approach and holder selection.

Can this insert be used for interrupted cuts? Yes, provided the setup and clamping are sufficiently rigid; the 0° relief angle and secure screw fixing support stability during interrupted turning.
