DNMG150408 AT9530 Tungaloy indexable insert 150408 for turning

DNMG150408 AT9530 is an indexable turning insert optimised for finishing and light machining of steel, designed to deliver consistent surface quality and predictable wear in ISO insert systems

• Coated cermet grade AT9530
• Rhombic DNMG 150408 geometry
• 0.8 mm corner radius for fine finishes
• Double-sided chipbreaker with cylindrical hole

High-quality finishing with coated cermet performance

The AT9530 coated cermet grade is engineered for finishing and light machining of steel, emphasising a fine surface result and steady flank wear. The microstructure of the cermet substrate, combined with a wear-resistant coating, reduces adhesion and built-up edge tendencies during low-to-moderate cutting forces, which translates into longer intervals between edge changes and a more consistent workpiece finish. As a consequence, production runs that prioritise dimensional accuracy and surface integrity can operate with fewer interruptions and more predictable results.

System compatibility and secure clamping for stable turning

This insert belongs to the ISO indexable turning insert family and requires a matching holder defined by geometry, relief angle, tolerance class, fastening method, size and thickness. The data sheet specifies a 15 mm size and a 4.76 mm plate thickness, with a cylindrical hole that supports precise locating and repeatable clamping. Correctly pairing the insert with the appropriate external holder or boring bar, plus the correct backing and clamping set, ensures stable cutting conditions and reduces vibration, which is essential for achieving the surface finish benefits offered by the grade.

Geometry and chip control that support consistent results

The rhombic plate form combined with a nominal approach angle of 55° and a 0° relief produces a cutting geometry that is well suited to both external and internal turning tasks where surface quality is paramount. The double-sided chipbreaker design promotes manageable chip formation during finishing passes, reducing the risk of tangling or workpiece damage. The 0.8 mm corner radius balances edge strength with the ability to achieve fine radii on the component, offering a compromise between durability and the aesthetic/functional demands of machined faces.

Practical application notes and process optimisation

For best results in finishing applications, select the chipbreaker and grade combination that matches workpiece material, machining strategy and machine-tool rigidity. The insert is intended primarily for steel, and its cermet composition supports low cutting forces in fine-turning regimes. The recommended system configuration comprises the ISO insert, a compatible external holder or boring bar, the correct backing/clamping kit and replacement screws. Regular inspection of seat surfaces and torque control on the clamping screws contributes to repeatability and tool life, helping to exploit the AT9530 advantages in everyday production.

FAQ

What distinguishes the AT9530 grade from other inserts?
The AT9530 grade is a coated cermet developed for finishing and light machining of steel; the DNMG150408 AT9530 Tungaloy indexable insert (SKU 6773692-Tungaloy) provides enhanced surface quality and uniform wear compared with conventional carbide grades in comparable finishing tasks.

Is this insert suitable for both external and internal turning?
Yes, the rhombic geometry and double-sided chipbreaker make the DNMG150408 AT9530 suitable for both external and internal turning operations when paired with the correct holder and clamping components.

Can the insert be indexed to use both cutting edges?
The insert is double-sided and designed for indexing; the DNMG150408 AT9530 Tungaloy indexable insert (manufacturer item no. 6773692) allows cost-effective reuse of multiple cutting edges subject to correct handling and seating.

How does one ensure holder compatibility for this ISO insert?
Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness — check that the chosen holder matches the DNMG150408 dimensions (15 mm size, 4.76 mm thickness) and mounting features before assembly.

What are the key dimensions and geometry to note for setup?
Key values are: plate size 15 mm, thickness 4.76 mm, corner radius 0.8 mm, approach angle 55° and a relief angle of 0°; the insert also features a cylindrical locating hole for secure clamping.
