DNMG150408 NS9530 Tungaloy — ISO turning indexable insert for finishing, rhombic 55° geometry

The DNMG150408 NS9530 is an ISO rhombic indexable insert for turning, developed as a finishing grade for steel with a sharp cutting edge and low cutting forces.

• Sharp cermet cutting edge for high finish
• Rhombic 55° geometry for stable cuts
• Double-sided with cylindrical hole for economy
• Low cutting forces for continuous turning

Consistent surface finish for finishing operations

The uncoated NS9530 grade delivers a cermet composition that is engineered for low cutting forces and a fine surface finish on steel workpieces. By combining a sharp edge geometry with a modest corner radius of 0.8 mm, the design reduces vibration and promotes continuous cutting regimes, which benefits repeatability and reduces the need for rework. The focus on finishing means fewer passes are required to reach final dimensions, increasing throughput without sacrificing quality.

Geometry and clamping compatibility that reduce setup time

A rhombic insert form with a 55° approach angle and 0° relief provides a predictable cutting orientation that suits common ISO holders. The insert’s rhombic shape and cylindrical hole permit secure clamping and easy indexing, while the 4.76 mm thickness and 15 mm size ensure mechanical stability during external and internal turning. Clear specifications on shape, size, thickness and hole style simplify holder selection and minimise downtime during tool changes.

NS9530 uncoated cermet: lower forces and improved surface integrity

As an uncoated cermet finishing grade, NS9530 offers a balance between hardness and edge stability that is beneficial for continuous finishing cuts on steel. The material choice promotes a clean, sharp edge that resists chipping under low feed/high speed conditions and supports improved surface integrity. For shops seeking predictable tool life and excellent part appearance, this finishing insert is optimised for applications where consistent dimensional and visual quality matters.

Integration into production for efficient tool use and economy

The double-sided construction with a double-sided chipbreaker and a central cylindrical hole extends usable life and reduces per-part tooling cost by allowing indexing. As an ISO-standard insert, it fits standard holders when form, clearance angle, tolerance class, fastening and thickness match, which streamlines inventory management. Where stable chip control and low cutting forces are required, this insert supports reliable, productive turning operations with fewer interruptions.

FAQ

What materials is this insert suited for?
The DNMG150408 NS9530 Tungaloy insert is specified as a finishing grade primarily for steel, where its uncoated cermet composition provides low cutting forces and a high-quality surface.

Can the insert be used in standard ISO holders?
Yes. The ISO designation DNMG150408 and the defined thickness, size and hole style allow use in compatible ISO holders when form, clearance and fastening match.

How does the NS9530 grade affect machining strategy?
NS9530 is an uncoated finishing grade that favours continuous cuts with small depths of cut and moderate speeds to achieve superior surface finish and repeatable dimensional results.

Is the insert indexable and economical for production?
The double-sided design with a cylindrical hole permits indexing and reuse of both cutting edges, extending tool life and lowering per-part tooling costs.

What edge geometry does this insert provide for turning?
The insert features a rhombic shape with a 55° approach angle and a 0° relief, supporting stable cutting orientation and easy tool set-up for both external and internal turning.
