DNMG 150612 T505 turning insert – Tungaloy

The DNMG150612 T505 is an ISO-standard indexable turning insert engineered for economical and stable machining of cast iron in general turning applications.

• CVD-coated carbide grade T505 for cast iron
• 55° rhombic geometry for stable cutting
• 1.2 mm corner radius for robust edge strength
• Cylindrical hole, 6.35 mm thickness for secure clamping

Increase productivity with a grade built for cast iron

The combination of CVD-coated carbide and the T505 grade is optimised for the economical machining of cast iron, delivering a balance of wear resistance and edge toughness. The coating minimises built-up edge and adhesive wear during interrupted cuts, while the substrate offers fracture resistance—resulting in longer effective tool life and fewer tool changes. For production environments where cycle time and predictable tool behaviour matter, this insert supports consistent throughput and reduced process variation.

Reliable chip control and surface quality on the workpiece

Equipped with a double-sided chipbreaker, the insert promotes controlled chip formation across common cast-iron grades. Controlled chips reduce the risk of entanglement and improve surface finish, so finishing passes are more predictable and less reliant on manual rework. The 55° rhombic geometry helps maintain a low cutting force direction, which contributes to dimensional stability of the turned part and reduces the load on the machine spindle.

Designed for secure clamping and easy integration

The ISO DNMG form and the cylindrical central hole ensure compatibility with standard external toolholders and boring bars when the holder matches form, clearance angle and tolerance class. A plate thickness of 6.35 mm and the 1.2 mm corner radius give mechanical robustness in less rigid set-ups; this reduces the chance of edge chipping during light interruptions or unstable clamping conditions. The insert is reversible, allowing both sides to be used for economical indexable performance.

Practical advantages that lower overall tooling cost

Selecting the T505 grade for cast iron workpieces reduces the frequency of insert replacements and keeps machine uptime high. The insert’s construction supports higher feed rates where the process is stable, enabling faster material removal rates and better cost per part. For workshops aiming to streamline operations, the combination of geometric stability and an application-optimised grade translates into measurable savings over longer runs.

FAQ

What materials is this insert suitable for? This DNMG150612 T505 insert from Tungaloy is designed primarily for economical machining of cast iron and performs best when matched to the appropriate chipbreaker and cutting conditions.

How does the T505 grade influence performance? The T505 grade provides a CVD-coated carbide surface with a substrate tuned for wear resistance and edge strength, giving stable tool life during continuous and interrupted turning of cast iron.

Is the insert reversible and how many cutting edges are available? The rhombic DNMG plate is double-sided; each side can be indexed to present a fresh cutting edge, extending the usable life compared with single-edged designs.

What holder compatibility should be checked before ordering? Compatibility depends on the insert form, clearance angle (0°), tolerance class, fixing method and plate thickness; confirm the holder accepts DNMG 150612 geometry and a 6.35 mm thick plate.

Can this insert cope with interrupted cuts? Yes—the carbide substrate and the chosen chipbreaker make the insert suitable for interrupted cutting typical in cast iron work, provided cutting parameters and clamping stability are adequate.
