DNMG 150408 T5105 DNMG — Indexable insert for turning, Tungaloy

A DNMG150408 T5105 indexable insert for demanding external and internal turning operations, designed for high-speed machining of cast iron under stable cutting conditions.

• CVD-coated carbide for high-speed cutting
• 55° rhombic geometry for versatile turning
• 0.8 mm corner radius for robust edge strength
• Double-sided insert with cylindrical hole

Consistent high-speed performance through advanced grade design

The T5105 grade is a CVD-coated carbide developed for high-speed machining of cast iron, offering superior wear resistance and long tool life under stable cutting conditions. The coating reduces flank wear and improves resistance to abrasive cast-iron constituents, which translates into longer uninterrupted cutting cycles and fewer tool changes. This results in a measurable increase in productivity on series production and maintenance of surface finish quality even at elevated cutting speeds.

Geometry and form that enhance process stability

A 55° rhombic geometry combined with a 0° clearance angle gives the insert versatility for both profiling and light shoulder turning while maintaining access in confined features. The 0.8 mm corner radius strengthens the cutting edge against edge chipping and improves load distribution in interrupted cuts. The double-sided design and cylindrical hole enable secure mounting and economical indexation, while compatibility with ISO-compliant external holders supports straightforward integration into existing tool systems.

System-level benefits for reliable machining and predictable results

Use of these inserts within a complete system — insert, matching external holder or boring bar, underlay/clamp set and replacement screws — ensures stable clamping and repeatable positioning, which are crucial for dimensional consistency and reproducible surface finish. The double-sided chipbreaker arrangement permits controlled chip formation when paired with an appropriate grade and cutting geometry, reducing the risk of chip entanglement and facilitating safe evacuation in automated setups. Specification-driven selection of holder and operating parameters makes this insert a practical choice for production environments seeking predictable cycle times and lower tool-change frequency.

FAQ

Which materials is this insert optimised for?
The DNMG150408 T5105 insert is optimised for high-speed machining of cast iron, with a CVD-coated carbide grade that improves wear resistance and surface quality.

Is the DNMG150408 compatible with standard holders?
Yes, the insert follows ISO dimensions and is compatible with ISO-compliant external holders when the holder matches the plate form, size, thickness and tolerance class.

What is the purpose of the 0.8 mm corner radius?
The 0.8 mm corner radius increases edge strength and distributes cutting forces more evenly, reducing the likelihood of chipping in interrupted or heavy cuts.

How does the T5105 coating benefit production runs?
The T5105 CVD coating enhances abrasion resistance and flank wear performance, extending tool life and reducing downtime for tool changes during series production.

Can the insert be indexed to use both sides?
Yes, the insert is double-sided and can be indexed to present a fresh cutting edge, improving cost-efficiency per insert.
