DNMA 150612 T5105 indexable turning insert — ISO DNMA rhombic, 55° cutting angle (Tungaloy)

The DNMA150612 T5105 is an ISO rhombic indexable insert engineered for turning applications, especially high-speed, stable machining of cast iron components.

• CVD-coated carbide grade T5105 for wear resistance
• ISO DNMA 150612 rhombic insert, 55° cutting angle
• 1.2 mm corner radius for predictable profile control
• Cylindrical hole, 6.35 mm thickness for ISO holders

Enhanced productivity through wear-resistant cutting grade

The CVD-coated carbide T5105 delivers a balance of high wear resistance and cutting-edge durability for demanding turning operations. In practice, the coating reduces flank and crater wear during sustained high-speed work, which translates into longer tool life and fewer indexings. For production environments processing cast iron, the combination of the CVD coating and a robust carbide substrate reduces unplanned tool changes and supports a more economical cost per component. The emphasis on measurable longevity and consistent surface finishes prioritises process reliability and predictable planning for batch production.

Geometry tuned for dimensional control and chip behaviour

The ISO DNMA rhombic geometry with a 55° cutting angle provides favourable entry conditions for both external and internal turning cycles, improving access and minimising tool deflection in typical setups. A 1.2 mm corner radius gives stable edge strength for profile retention while limiting burr formation; this aids repeatable tolerances on turned diameters and shoulders. The insert’s cylindrical hole and 6.35 mm plate thickness ensure secure clamping and compatibility with standard ISO external holders and boring bars, enabling accurate seat positioning and reduced vibration. These geometric features support steady cutting forces and contribute directly to improved workpiece quality.

System integration and process advantages for workshop efficiency

The insert is designed as part of an ISO-compliant system: indexable insert, matching external holder or boring bar, and the required shim/clamp set with replacement screws. Absence of an integrated chipbreaker means chip control should be selected according to workpiece material, cutting parameters and stability of the setup; the T5105 grade excels when stable clamping and moderate depths of cut are used. For production lines seeking consistent throughput, this approach allows optimisation of cutting data and minimises variability. The result is smoother tool management, fewer interruptions and a more predictable manufacturing rhythm — especially valuable in series turning.

FAQ

What materials is this insert designed for?
The DNMA150612 T5105 indexable turning insert is optimised for machining cast iron and performs best under stable clamping and cutting conditions.

Is the insert supplied with a chipbreaker?
No; the DNMA150612 insert is delivered without a chipbreaker so that chip control can be matched to the workpiece, cutting data and machine setup.

Which holders are compatible with this DNMA insert?
Compatibility is determined by ISO DNMA form, relief angle, tolerance class, fixing method, size and thickness; the insert fits standard ISO DNMA holders and boring bars when dimensions match.

How does the T5105 grade affect tool life?
The CVD-coated T5105 grade enhances wear resistance and provides stable edge retention during high-speed turning, which generally extends tool life in production runs.

Can this insert be used for internal turning as well as external turning?
Yes; the rhombic DNMA geometry and 55° cutting angle allow use in external and certain internal turning operations where access and holder geometry permit.
