DNMG150408 AT9530 turning insert — rhombic 55° for turning (Tungaloy)

The DNMG150408 AT9530 is an ISO-standard rhombic turning insert designed for finish and light turning of steel, offering a coated cermet grade for improved surface quality and consistent wear behaviour

• Coated cermet AT9530 for fine surface finish
• Rhombic 55° geometry for versatile turning
• Double-sided chipbreaker for stable machining
• Cylindrical hole for secure mounting

Consistent finish and controlled wear for steel turning

The coated cermet AT9530 grade prioritises surface quality and even wear, making it particularly suitable for finish and light machining of steel components. The coating improves edge integrity and reduces built-up edge during low- to medium-depth cuts, which translates into fewer surface rework cycles and more predictable component quality. The combination of a fine-grain substrate and a tailored coating enables the insert to maintain a sharp cutting profile across longer tool life, supporting stable dimension and surface consistency in production runs.

Design that supports versatile turning operations

With a rhombic 55° geometry and an inscribed-circle size of 15 mm, this insert suits a wide range of external and internal turning tasks where access and approach angles matter. The 0° clearance/rake angle provides a neutral cutting action that helps maintain form and avoids excessive cutting forces in finish applications. The 0.8 mm corner radius offers a balance between edge strength and surface finish; the modest radius reduces the risk of chatter while preserving fine edge definition. Compatibility with ISO holders depends on form, clearance angle, tolerance class, fastening and plate thickness, ensuring safe and repeatable clamping when the correct holder is selected.

Practical chip control and secure clamping for productivity

The double-sided chipbreaker design promotes predictable chip formation in finish turning, reducing the incidence of long, stringy chips that can interrupt automated processes. The insert’s cylindrical hole enables positive mechanical location and reliable screw clamping, supporting repeatable seating and easier indexation when the cutting edges are rotated. These mechanical features reduce set-up variation and support higher machine uptime, which is critical in both job-shop and production environments that prioritise process reliability.

Selection guidance and application scenarios

Choose this insert when the priority is high surface quality on steel parts produced by finish or light turning, and when consistent wear behaviour is required across batches. The plate thickness of 4.76 mm and ISO designation 150408 indicate the insert’s structural rigidity and form factor; match the insert to a compatible external holder or boring bar that accommodates the rhombic form and the 4.76 mm thickness. For less stable set-ups or heavy interrupted cuts, consider larger corner radii or different grades optimised for roughing to protect the cutting edge.

FAQ

What material applications suit this insert best? The insert is optimised for finish and light turning of steel, with the AT9530 coated cermet designed to deliver good surface finish and uniform wear on such materials.

How is the insert fixed in the holder? The rhombic plate features a cylindrical hole and is secured by screw clamping to compatible ISO turning holders; correct holder selection ensures reliable clamping for the DNMG150408 AT9530 insert.

What does the designation DNMG150408 indicate? DNMG denotes the rhombic plate form, and the ISO code 150408 specifies the inscribed circle size, thickness and corner radius attributes that define the insert’s geometry.

Is this insert indexable on both sides? Yes, the insert is double-sided with a chipbreaker on both cutting edges, allowing indexation to use multiple edges and extend productivity between tool changes.
