DNMA 150404 T5105 – Indexable turning insert, CVD-coated carbide, 55° rhombic by Tungaloy

The DNMA150404 T5105 is an ISO-format indexable turning insert designed for high-speed external and internal turning of cast iron under stable machining conditions.

• CVD-coated carbide T5105
• Optimised for high-speed cast iron turning
• ISO DNMA 150404 rhombic 55° form
• Cylindrical hole for secure clamping

Consistent high-speed performance for cast iron components

The DNMA150404 T5105 indexable insert combines a CVD-coated surface with a robust carbide substrate to withstand the demands of high-speed turning on cast iron. The T5105 grade is formulated for wear resistance under continuous cutting, which reduces flank wear and extends tool life in stable setups. For workshops focused on throughput, this means fewer insert changes and more time on productive machining, while the rhombic geometry contributes to predictable cutting forces and process stability.

Reliable mounting and ISO compatibility reduce setup time

The insert’s ISO format and defined form ensure compatibility with a wide range of holders when matching is done by form, relief angle, tolerance class, fastening and thickness. The cylindrical hole and precise 0° relief angle provide a secure attachment and repeatable positioning, supporting accurate index changes and consistent cutting performance. Clear compatibility reduces setup errors and shortens fixture time, improving overall shop efficiency.

Coating and substrate explained for practical decisions

A CVD-coated layer on a carbide base offers a balance of adhesion and thermal resistance suited to abrasive materials such as cast iron. The coating minimises abrasive wear and protects the cutting edge at elevated temperatures, while the carbide core supplies the necessary toughness. This combination is particularly suitable where a smooth rake and controlled edge preparation are required to avoid premature chipping and to maintain surface finish quality.

Productivity gains and workshop benefits

Using an insert engineered for cast iron turning delivers measurable benefits: stable chip formation, predictable tool life and reduced downtime for tool changes. The rhombic 55° form with a 0.4 mm corner radius helps to distribute cutting loads and supports smooth engagement in both external and internal turning. When paired with a suitable holder and clamping set, this insert contributes to repeatable processes, consistent component quality and efficient material removal rates.

FAQ

What materials is this insert suitable for?
The DNMA150404 T5105 insert from Tungaloy is designed primarily for high-speed turning of cast iron; its CVD-coated carbide construction provides abrasion resistance suited to that material class.

How does the 55° rhombic form affect machining?
The 55° rhombic geometry balances cutting stiffness and accessibility, enabling effective external and internal turning operations with the DNMA150404 indexable insert.

Is a chipbreaker included with this insert?
This particular insert is supplied without a chipbreaker; the open configuration of the DNMA150404 T5105 supports stable chip flow under the recommended cutting conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the DNMA150404 format is compatible with standard ISO DNMA holders that accept a 15 mm rhombic insert with a cylindrical hole.

Can the coating extend tool life in high-speed cutting?
Yes, the CVD coating on the T5105 grade enhances wear resistance at elevated temperatures, contributing to longer life during high-speed cast iron turning.
