DNMG150404 NS9530 — Tungaloy indexable turning insert (uncoated cermet, finishing for steel)

The DNMG150404 NS9530 Tungaloy insert is designed for precision external and internal turning, offering a finishing-grade solution for continuous cuts and small depth-of-cut operations.

• ISO DNMG geometry for standard toolholders
• Uncoated cermet grade NS9530 for finishing
• Double-sided chipbreaker for reliable chip control
• Sharp cutting edge for low cutting forces

Consistent finishing and low cutting forces for superior surface quality

The NS9530 grade is an uncoated cermet engineered for finishing cuts on steel, combining a sharp cutting edge with reduced cutting forces to improve surface appearance and dimensional consistency. Cermet substrates provide fine-grain hardness and thermal stability that help maintain a clean cut during continuous operations and small depth passes. For production environments requiring repeatable part finish, this grade supports improved machining stability and easier attainment of target tolerances without the need for heavy machining parameters.

Plug-and-play compatibility for ISO tool systems

The insert follows the ISO DNMG150404 geometry and is compatible with matching DNMG toolholders when the form, relief angle, tolerance class, clamping method, size and thickness correspond. Key dimensional characteristics include a 15 mm inscribed circle, 4.76 mm thickness, rhombic shape, a 0.4 mm corner radius and a 55° approach angle with a 0° relief angle; the piece features a cylindrical hole for secure indexing. Understanding these parameters simplifies holder selection and reduces trial-and-error during tool changeover, enabling quicker setup and consistent cutting performance.

Reliable chip control and productive indexing

Equipped with a double-sided chipbreaker, the insert supports efficient chip formation and evacuation during turning, which reduces cycle interruptions and improves process reliability. Being double-sided also increases usable edge count, which contributes to lower tool change frequency and better economics in batch production. For machining centres and lathes focused on throughput and surface finish, the chip control design helps prevent built-up edge and maintains steady cutting behaviour under continuous feed conditions.

Practical system advice and recommended use

The system comprises the insert, a compatible external holder or boring bar, a shim/clamping set and replacement screws. Select the NS9530 finishing grade and the appropriate chipbreaker based on workpiece material, machining method and machine/tool stability. The insert performs best in finishing applications on steel under steady-cut regimes and small depths of cut; choose stable fixturing and the correct holder geometry to exploit the grade’s low cutting-force advantage and to achieve the desired surface finish.

FAQ

What machining operations suit this insert best?
The DNMG150404 NS9530 insert is optimised for finishing in external and internal turning on steel, delivering high surface quality in continuous-cut and small-depth operations.

How does the NS9530 grade affect cutting forces?
The NS9530 uncoated cermet grade features a sharp cutting edge that produces low cutting forces, which assists in achieving improved surface finish and reduces stress on the workpiece.

Can the insert be indexed to use multiple cutting edges?
Yes; the insert is double-sided with a cylindrical hole and can be indexed to access fresh edges, improving edge utilisation and uptime.

Which holder characteristics are required for compatibility?
Compatibility depends on matching the DNMG form, relief angle, tolerance class, clamping style, size (15 mm) and thickness (4.76 mm) of the insert; select a corresponding ISO DNMG toolholder.

Is the DNMG150404 NS9530 suitable for interrupted cuts?
The grade is optimised for continuous cutting and small cuts; for heavy interrupted cuts, consider a grade designed for higher toughness rather than this finishing cermet.
