DNMA 150404 T505 Turning Insert — ISO turning insert for turning, rhombic 55° (Tungaloy)

The DNMA 150404 T505 is an ISO-standard rhombic turning insert designed for external and internal turning operations, offering a CVD-coated carbide grade engineered for productive machining of cast iron.

• ISO DNMA 150404 geometry, 55° rhombic
• CVD-coated carbide grade T505 for cast iron
• 0.4 mm corner radius for fine finishing
• Cylindrical hole, 4.76 mm plate thickness

Increased process efficiency for cast iron turning

The combination of a CVD-coated surface and the T505 carbide grade ensures balanced wear resistance and economical tool life when machining cast iron. The coating minimises built-up edge and improves thermal stability, which translates into fewer insert changes and more productive cutting cycles. With the rhombic geometry and a 55° approach angle, the insert supports stable engagement and consistent chip flow, enabling higher effective machining time and reduced downtime for set-up adjustments.

Reliable mounting and dimensional compatibility

Designed to ISO standards, this indexable insert offers predictable fitment in holders that match form, clearance, tolerance class, fastening and thickness. The part’s cylindrical hole and standard dimensions mean secure clamping and repeatable positioning in a wide range of external holders and boring bars. Specified thickness and the 0° clearance angle permit accurate axial and radial placement, helping to maintain part tolerances and reduce rework in serial production.

Fine finishing and stable cutting behaviour

With a 0.4 mm corner radius and an absence of a dedicated chipbreaker, this insert is well suited to finishing passes and steady turning conditions where smooth surface integrity is required. The geometry supports controlled chip formation when matched to suitable cutting parameters and a stable machine set-up. System components typically include the ISO insert, a compatible external holder or boring bar, and the required clamping set and screws to maintain consistent performance in batch or single-piece production.
