DNMG 150404 AT9530 Tungaloy – Indexable turning insert for Turning, 55°

DNMG150404 AT9530 indexable insert for precision external and internal turning applications, designed for fine finishing of steel components

• ISO-standard rhombic insert geometry
• AT9530 grade for fine finishing
• Double-sided chipbreaker for stability
• Cylindrical hole for secure mounting

Precision finishing that reduces rework and process variability

The DNMG150404 AT9530 Tungaloy insert is engineered for fine and light machining of steel, where surface integrity and even wear behaviour are key. Its AT9530 coated cermet composition combines hardness and thermal stability to deliver improved surface finish while reducing burr formation. The ISO‑compliant rhombic shape and 55° approach angle provide a predictable cutting direction that helps to lower cutting forces and minimise tool deflection, which in turn reduces the need for rework and extends cycle‑time consistency.

Geometry and clamping that ensure reliable repeatability

A 0.4 mm corner radius, 4.76 mm plate thickness and a cylindrical mounting hole contribute to mechanical stability in a wide range of ISO turning holders. The double‑sided chipbreaker design allows the insert to be indexed, doubling effective tool life in appropriate applications and improving cost efficiency per edge. Compatibility with holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness — this ensures secure clamping and repeatable positioning for series production.

Material behaviour and process benefits explained

The coated cermet grade is optimised for finishing operations on steel, emphasising uniform wear and high quality surface results rather than aggressive metal removal. Reduced built‑up edge formation and better wear distribution are notable advantages when machining alloys where surface tolerance and appearance matter. The combination of material selection and chip control translates into fewer interruptions for tool changes and more predictable tool life in finely tuned machining strategies.

Practical selection guidance for shops and production lines

Select the chipbreaker and grade based on material, machining type and machine stability: the double‑sided chipbreaker suits stable set‑ups and finishing passes, while the 55° geometry is favourable for maintaining dimensional control on external profiles and internal bores. For integration into an existing workflow, match the insert to the holder form and tolerance class; consult tooling tables for feed and speed recommendations to exploit the AT9530 behaviour fully. If uncertainty remains regarding process parameters or compatibility, technical advice is available to support the decision.

FAQ

What applications are best suited to this insert?
The DNMG150404 AT9530 Tungaloy insert is intended primarily for fine and light finishing of steel in external and internal turning operations, where surface quality and uniform wear are priorities.

Can the insert be indexed to use both cutting edges?
Yes, the double‑sided chipbreaker and rhombic geometry permit indexing to a fresh edge, effectively extending usable life under suitable cutting conditions.

Which material grade is used and what advantage does it offer?
The insert uses the AT9530 cermet grade, which delivers improved surface finish and steady wear behaviour in finishing passes on steel.

How does the 55° approach angle affect machining?
A 55° approach angle reduces radial cutting forces compared with steeper angles, aiding dimensional control and reducing deflection during profiling and internal turning.

Is holder compatibility standardised?
Compatibility follows ISO norms: form, clearance angle, tolerance class, fastening, size and thickness determine whether an insert seats and clamps correctly in a given holder.
