DNMA 150408 T5105 Turning insert — CVD-coated carbide, 55° geometry (Tungaloy)

DNMA150408 T5105 is a rhombic ISO turning insert designed for high-speed machining of cast iron and for general external and internal turning applications.

• ISO 150408 form for standardised clamping
• CVD-coated carbide grade T5105 for cast iron
• Rhombic 55° geometry with 0° relief
• Cylindrical hole for secure fastening

High-speed machining with a wear-resistant grade

The CVD-coated carbide grade T5105 is formulated for high-speed machining of cast iron under stable conditions. Its wear-resistant composition enables consistent cutting-edge performance over extended runs, which reduces tool changes and minimises machine downtime. The combination of a robust coating and a precisely ground cutting edge supports predictable tool life and reliable part tolerances, translating directly into improved process efficiency for serial turning operations.

Clear compatibility and secure clamping for predictable setups

Being ISO-compliant, the insert follows industry-standard dimensions so compatibility with matched holders is straightforward. The rhombic shape, the 55° cutting angle and the 0° relief angle define the seating and engagement characteristics; the cylindrical hole ensures positive clamping with standard screws and seats. This clarity in interface parameters shortens setup time, simplifies tool inventory management and reduces the risk of incorrect mounting that can cause chatter or premature wear.

Process security and repeatable surface quality

In stable machining conditions the grade delivers stable chip formation and consistent edge retention, which supports reproducible surface finishes and dimensional accuracy. Selecting this insert for appropriate cutting data and a compatible holder helps to lower overall tooling cost per part through fewer interruptions and predictable wear patterns. For customers focused on output consistency, the combination of geometry and coating offers tangible improvements in productivity and part quality.

System considerations and recommended applications

The insert is intended for use as part of a system: ISO turning insert, matched external holder or boring bar, an appropriate shim/clamp set and replacement screws. Typical operations include external and internal turning on cast iron workpieces; no chipbreaker is fitted, so a chip-control solution should be chosen according to material and stability. For finishing cuts the fine edge and coating help achieve good surface results; for roughing choose conservative depth and feed and verify stability before stepping up to high-speed parameters.

FAQ

Is this insert compatible with standard ISO DNMA holders?
The DNMA150408 T5105 insert follows the ISO 150408 form and is compatible with holders specified for DNMA inserts, provided the holder matches the geometry, thickness and tolerance class.

For which materials is the T5105 grade recommended?
Tungaloy formulated the T5105 grade for wear-resistant performance in cast iron at elevated speeds; it is optimised for stable machining conditions where consistent edge life is required.

Can the insert be used for finishing operations?
Yes, the CVD-coated carbide surface and fine cutting edge suit finishing cuts on cast iron when machine and setup stability are ensured; adjust feeds and depths to achieve the desired surface quality.

How should chip control be handled given the absence of a chipbreaker?
Because this insert is supplied without a chipbreaker, select a suitable holder or external chip-control device and adapt cutting parameters to the workpiece and rigidity to manage chip formation effectively.

What is the correct reference for reordering?
Order using the article number 6850200 or the seller SKU 6850200-Tungaloy to ensure the correct DNMA150408 T5105 turning insert is supplied.
