DNMA150404 T515 indexable insert for turning — Tungaloy CVD‑coated carbide, 55° rhombic, 0.4 mm radius

The DNMA150404 T515 is an ISO‑standard rhombic indexable insert for turning, optimised for economical machining of cast iron through a CVD‑coated carbide grade and a robust geometry suitable for both external and internal operations

• ISO rhombic insert, 55° cutting angle
• CVD‑coated carbide grade T515 for cast iron
• 0.4 mm nose radius for versatile finishing
• Central cylindrical hole for secure clamping

Consistent productivity for cast‑iron turning

The combination of a CVD‑coated substrate and the T515 grade delivers a cost‑effective balance between tool life and cutting performance for cast iron workpieces. The stabilised coating reduces wear during continuous operations, which translates into fewer indexings and lower tooling costs over time. As an ISO‑compliant insert, it integrates into standard indexable insert tool systems, ensuring predictable behaviour when the holder form, clearance angle, tolerance class, clamping method, size and thickness match. This predictability supports steady cycle times and simplifies process planning in series production.

Stable cutting geometry for dimensional accuracy

A 55° rhombic shape with a 0.4 mm nose radius provides a reliable compromise between edge strength and surface finish, making this geometry suitable for light to medium finishing passes as well as general turning. The 0° clearance (relief) angle and the plate thickness of 4.76 mm contribute to rigidity at the cutting edge, reducing vibration and run‑out sensitivity in standard external and internal turning setups. The central cylindrical hole enables secure positive clamping, so the cutting conditions remain stable over longer tool life and part batches, supporting repeatable tolerances and improved first‑pass quality.

System compatibility and application guidance

Designed as an ISO turning insert, the DNMA150404 fits into a modular system consisting of an appropriate external holder or boring bar, shim/clamping set and replacement screws; correct selection of holder style and tolerance class is essential for optimal performance. The plain geometry is supplied without a chipbreaker, which is advantageous for stable, uninterrupted cuts and predictable chip flow in robust setups; when machining interrupted cuts or when enhanced chip control is required, alternative geometries or a dedicated chipbreaker grade should be selected. The manufacturer SKU (TUN6743710) and article number (6743710) identify the original Tungaloy product for procurement and traceability.

FAQ

What materials is this insert intended for?
The DNMA150404 T515 insert is designed primarily for the economical machining of cast iron, using the CVD‑coated T515 carbide grade to balance wear resistance and cost.

What are the geometric characteristics of this insert?
This turning insert features a 55° rhombic shape, a 0.4 mm nose radius, 15 mm size, 4.76 mm thickness and a central cylindrical hole for secure clamping; it is identified under SKU TUN6743710 and article number 6743710.

How is compatibility with a toolholder determined?
Compatibility is governed by the insert form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters to the holder ensures correct seating and cutting behaviour.

Does the insert have a chipbreaker?
No, this particular insert is supplied without a chipbreaker, which suits stable, continuous cuts; for interrupted cuts or finer chip control, a chipbreaker version should be chosen.

What coating and substrate does the insert use?
The insert uses a CVD‑coated carbide substrate in grade T515, selected for productive, economical machining of cast iron.
