DNMG 150604 NS520 — Turning indexable insert DNMG150604 by Tungaloy

DNMG150604 NS520 is an ISO-format indexable insert for turning, designed for fine finishing and light machining of steel with a focus on surface integrity and repeatable dimensional accuracy.

• DNMG150604 format, 55° lead angle
• NS520 cermet for fine finishing
• Double-sided chipbreaker, cylindrical hole

Precision finishing and consistent wear for turning

The NS520 grade is a cermet or coated cermet designed specifically for finishing to light machining of steel, delivering an improved surface finish and uniform flank wear. Cermet combines ceramic hardness with metallic toughness, which reduces built-up edge and stabilises cutting performance; this makes the insert particularly suitable where surface integrity and dimensional control are priorities. The rhombic geometry with a 55° lead angle supports stable external and internal turning processes while the 0.4 mm corner radius helps to achieve consistent edge strength without sacrificing fine finish.

Compatibility and system requirements explained

Compatibility with toolholders is determined by the insert’s form, clearance angle (0°), tolerance class, mounting feature, size and thickness. The DNMG-format insert requires a matching external holder or boring bar together with a shim/clamp set and replacement screws for a correct clamping system. Inserts are ISO-standard, which simplifies selection when holders are specified by form and size; however, the chosen holder must accept an insert with a 6.35 mm thickness, an inscribed circle of 15 mm, and a cylindrical hole for secure fixing and repeatable positioning.

Practical advantages of the chipbreaker and geometry

The double-sided chipbreaker on this insert promotes reliable chip control in finishing feeds, directing chips away from the workpiece and supporting stable cutting conditions. As the grade is intended for fine turning, predictable chip formation contributes to longer tool life and reduced surface rework. The rhombic plate form allows economical use of both sides of the insert, halving index costs per cutting edge under suitable process parameters.

Selecting cutting data and expected outcomes

When matched with appropriate speeds, feeds and stable clamping, the cermet composition of the NS520 grade enables improved surface roughness and repetitive dimensional results. For customers less familiar with the material, cermet inserts typically favour moderate cutting speeds and light depths of cut for finishing passes; this approach exploits the material’s wear resistance while preserving edge integrity. The result is a balance of productivity and finish quality that is especially advantageous in batch production and precision components.

FAQ

What holders are compatible with this DNMG insert?
Compatibility is based on the insert form, clearance angle, tolerance class, mounting type, size and thickness; the DNMG150604 NS520 insert fits holders specified for DNMG standard inserts and requires a matching shim/clamp arrangement.

Is NS520 suitable for roughing operations?
The NS520 grade is optimised for finishing to light machining on steel; for heavy roughing a more robust grade or alternative geometry would typically be recommended instead of the DNMG150604 NS520 insert.

How many usable cutting edges are available per insert?
The DNMG150604 format is double-sided; each side provides usable cutting edges according to the insert indexing practice, allowing economical use of the plate for finishing applications.

What are the main benefits of the cermet grade on this insert?
Cermet, as used in the NS520 grade, offers enhanced wear resistance and stable edge behaviour that contribute to improved surface finish and repeatable dimensional control when the DNMG150604 insert is applied under suitable finishing parameters.
