DNMG150404 NS9530 Tungaloy insert — ISO turning insert for fine finishing

DNMG150404 NS9530 Tungaloy insert is an ISO‑normed rhombic turning insert designed for fine finishing of steel components in continuous cutting operations.

• ISO DNMG shape, 55° cutting angle
• NS9530 uncoated cermet for fine finishing
• 0.4 mm nose radius for high surface quality
• Double-sided insert with cylindrical central hole

Optimised finishing for steel turning with predictable results

The NS9530 grade is an uncoated cermet developed for finishing operations on steel, offering a sharp cutting edge that reduces cutting forces and improves surface integrity. The small 0.4 mm nose radius combined with the 55° rhombic geometry produces high‑quality surface finishes on continuous cuts and small depth‑of‑cut conditions. For engineers seeking repeatable part quality, the material and geometry together minimise vibration sensitivity and support stable chip formation, which in turn reduces the need for secondary finishing.

Compatibility and secure clamping for production reliability

Manufactured to ISO dimensions, the DNMG150404 indexable insert fits common ISO holders when form, relief angle, tolerance class, fastening method, size and thickness are matched. The central cylindrical hole and the double‑sided design allow straightforward indexing and economical use of the cutting edges. Clear system understanding — insert, matching outside holder or boring bar, shim/clamp set and replacement screw — ensures rapid changeover and consistent seating, helping to maintain cycle times and reduce downtime in production environments.

Efficient machining thanks to targeted grade properties

The uncoated cermet chemistry of NS9530 is optimised for low cutting forces and excellent surface finish at finishing feeds and speeds. In practice this means reduced tool‑related rework and higher first‑pass yield for precision components. Where continuous cutting predominates, the sharp edge geometry and stable chip control yield a predictable tool life; the result is better process economics through lower variability and fewer unplanned interventions.

Practical handling and application advice for setup and use

The insert’s rhombic plate form (15 mm size) and 4.76 mm thickness provide mechanical stability while keeping the cutting edge accessible for fine turn finishing. Because holder compatibility depends on geometric match, selecting an ISO‑compliant holder with the correct relief and clamping geometry is essential; matching these elements preserves edge life and secures repeatable performance. For tailored recommendations regarding holder selection or cutting data for a particular steel grade, Metav Werkzeuge can advise on feed, speed and depth‑of‑cut settings to get optimal results from this finishing insert.

FAQ

What steels is this insert best suited for?
This DNMG150404 NS9530 Tungaloy insert is a finishing grade optimised for steel, offering low cutting forces and a sharp edge suitable for continuous cutting and small depths of cut.

Can the insert be indexed, and how many usable edges are there?
The insert is double‑sided with a central cylindrical hole, enabling indexing to multiple usable cutting edges; exact edge count depends on the holder and mounting orientation.

Which holder type is compatible with this ISO insert?
Compatibility requires a holder matching the DNMG form, relief angle, tolerance class, fastening method, size and thickness; Metav Werkzeuge can recommend appropriate ISO holders for stable clamping.

Is the NS9530 grade coated?
No — NS9530 is an uncoated cermet grade designed to provide a sharp edge for finishing applications on steel.
