Take advantage of the CVD-coated carbide grade T5105 and the 0.8 mm corner radius to secure high-speed, stable machining of cast iron; order the insert directly via Metav Werkzeuge or ask our consultants for cutting parameters and holder compatibility.

DNMG 150408 T5105 indexable turning insert by Tungaloy — rhombic ISO insert for turning

The DNMG150408 T5105 is an ISO-standard rhombic indexable insert designed for external and internal turning, optimised for high-speed machining of cast iron under stable conditions.

• DNMG150408 ISO rhombic geometry, 55° included angle
• CVD-coated carbide grade T5105 for high-speed cast iron
• 0.8 mm corner radius for robust edge strength
• Cylindrical-hole, double-sided insert for stable clamping

Consistent high-speed performance for cast iron

The CVD-coated carbide substrate in grade T5105 delivers wear resistance tailored to high cutting speeds when machining cast iron. This combination reduces flank wear and helps retain a sharp cutting edge over longer tool life, leading to fewer insert changes and higher component throughput. The coating process creates a hard, heat-resistant layer; for users less familiar with coatings, this means better protection against abrasion and thermal degradation during continuous spindle operation.

Reliable edge strength and chip control

With a 0.8 mm corner radius and a double-sided chipbreaker, the insert provides a balance between edge robustness and controlled chip formation. The moderate radius increases edge life in interrupted cuts while the chipbreaker geometry supports predictable chip flow, lowering the risk of built-up edge and improving surface finish of turned components. These characteristics are particularly beneficial for medium to heavy cross-sections where stability is required.

Simple integration with ISO toolholders and secure clamping

The rhombic ISO-standard form, cylindrical hole, and 55° geometry make the insert compatible with a wide range of external holders and boring bars when the holder's form, clearance, tolerance class, fastening and thickness are matched. The double-sided design doubles the available cutting edges per insert, offering economical edge utilisation. For practical setup, confirm the holder accepts the 15 mm inscribed circle and 4.76 mm thickness to ensure correct seating and clamping.

Process security and economical productivity

Selecting this CVD-coated grade for stable turning operations supports reproducible results and reduced downtime. The wear-resistant material and robust geometry translate into predictable interchange intervals and consistent surface quality, which is essential for production lines aiming at repeatability and high uptime. For shops focused on efficiency, the insert’s design helps to maintain cycle times while reducing per-part tooling cost.

FAQ

What materials is this insert best suited for?
The DNMG150408 T5105 insert is engineered for cast iron machining, with the T5105 CVD-coated carbide grade providing high-speed wear resistance suitable for stable turning operations.

Can the insert be used on internal bores as well as external turning?
Yes. The rhombic form and double-sided design allow use in both external holders and compatible boring bars, provided the holder matches the insert’s dimensions and clamping style.

How many cutting edges are available per insert?
As a double-sided insert, the DNMG150408 T5105 offers multiple effective edges; rotating or indexing the insert extends total usable life compared with single-sided solutions.

What does the 0° clearance angle mean in practice?
A 0° clearance angle indicates a neutral relief suited to a variety of turning tasks; it promotes stable contact with the workpiece and, together with the 0.8 mm corner radius, supports robustness in interrupted cuts.

Which holder details must be checked for compatibility?
Verify holder form, clearance angle, tolerance class, fastening method, inscribed circle (15 mm) and plate thickness (4.76 mm) to ensure proper seating and clamping of the insert.
