DNMA110412 T515 Tungaloy indexable insert for turning — CVD-coated cemented carbide, rhombic 55°

A DNMA110412 T515 indexable turning insert engineered for economical machining of cast iron, featuring a 55° rhombic form and a cylindrical hole for secure clamping.

• CVD-coated cemented carbide grade T515
• Optimised for economic cast iron machining
• Rhombic 55° geometry with cylindrical hole
• 1.2 mm corner radius and 4.76 mm thickness

Enhanced productivity through durable, coated carbide

The CVD-layered cemented carbide composition of this insert provides a significant increase in wear resistance and edge stability compared with uncoated grades. The T515 grade is formulated for efficient removal of cast iron, enabling longer periods between index changes and more consistent cycle times. For production environments where predictable tool life and low downtime are priorities, the coated substrate reduces flank wear and maintains surface finish quality across longer runs, translating into a lower cost per component and fewer machine interruptions.

Secure seating and geometry that stabilise cutting forces

The rhombic 55° plate form combined with a cylindrical hole and a plate thickness of 4.76 mm ensures reliable clamping and repeatable positioning in ISO-compliant holders. The insert’s 0° clearance angle contributes to a stable cutting edge engagement, particularly beneficial for straight turning and light roughing where lateral support matters. These dimensional attributes lower vibration risk and improve dimensional accuracy of the workpiece, which is especially relevant when working with brittle or variable cast iron materials where consistent chip formation and clamp stability are essential.

Practical sorting and economic advantages for workshop use

A 1.2 mm corner radius offers a resilient cutting edge that tolerates interrupted cuts and variable feed rates without premature chipping. The absence of an integrated chipbreaker means the cutting geometry should be paired with a suitable holder and process settings to manage chips effectively; the system typically comprises the insert, an appropriate external holder or boring bar, a backing shim or clamp set, and spare fixing screws. Selecting the right combination based on material, cut depth and machine rigidity delivers measurable savings: fewer index changes, improved throughput and predictable tool consumption, supporting lean production and controlled tooling budgets.

FAQ

What materials is this insert suited for?
The DNMA110412 T515 insert is optimised for machining cast iron; the T515 grade and CVD coating provide wear resistance and stable cutting for grey and ductile iron applications.

How does the rhombic 55° geometry affect performance?
A 55° rhombic form improves edge strength and accessibility on external and internal turning operations; combined with the insert’s thickness and hole it supports secure clamping and reduced vibration.

Is a chipbreaker included with this insert?
This insert is supplied without a chipbreaker; chip control is achieved via holder design and cutting parameters, so selection of the matching holder and process settings is important.

What does the 1.2 mm corner radius mean for machining?
The 1.2 mm corner radius increases edge robustness, making the insert suitable for interrupted cuts and higher feed scenarios while maintaining surface quality.

Which components are required for a complete tool system?
A complete system comprises the indexable insert, a compatible external holder or boring bar, a backing shim or clamp set, and the correct fixing screws; compatibility is determined by form, clearance, tolerance class, fixing method, size and thickness of the insert.
