DCMT070204 NS9530 ISO turning insert for finishing — Tungaloy

The DCMT070204 NS9530 is an ISO-standard rhombic turning insert designed for precision finishing operations in turning, offering a sharp cutting edge and low cutting forces for continuous cuts.

• ISO rhombic insert, 55° geometry
• Uncoated cermet grade NS9530 for finishing
• Cylindrical hole with single-sided countersink
• Precise 0.4 mm corner radius for fine finishes

Precision finishing and surface quality for Stahl components

The uncoated cermet NS9530 is engineered as a finishing grade with a sharp cutting edge that reduces cutting forces and improves surface integrity. The combination of a 0.4 mm corner radius and 55° geometry yields a controlled cut that minimises vibration and leaves a consistent surface finish, making it particularly suitable for continuous turning and small depths of cut. For manufacturers seeking reproducible part quality, the low-friction cutting action of this grade reduces the need for secondary finishing and supports higher first-pass yields.

Reliable fit and secure clamping for uninterrupted production

As an ISO-standard DCMT insert, compatibility with the toolholder is governed by form, 7° relief angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole with a single-sided countersink (40°–60°) to ensure stable clamping and repeatable seating in compatible holders or boring bars. The 2.38 mm plate thickness and standard 07 size provide predictable rigidity when paired with the correct shim or clamp set; the recommended system comprises the insert, a matching outer holder or boring bar, an underlay/clamp set and spare fixing screws to maintain uptime.

Efficiency, process stability and application guidance

Choosing the right chipbreaker and grade for the machining task is essential: the single-sided chipbreaker and uncoated cermet composition favour finishing of Stahl, delivering both dimensional control and excellent surface texture. The modest cutting forces associated with this combination reduce tool wear on the holder and machine spindle, which can translate into longer tool life and lower overall machining costs per part. For process planning, specify the chipbreaker geometry and stability level that match the component, machining parameters and machine condition. If application-specific recommendations are required, Metav Werkzeuge can advise on cutter selection and parameter windows to optimise throughput and quality.

FAQ

Which materials is the DCMT070204 NS9530 best suited for? The DCMT070204 NS9530 insert is a finishing grade primarily for machining Stahl, offering a sharp edge and low cutting forces suited to continuous cuts.

Is this insert suitable for internal as well as external turning? Yes, the ISO rhombic form and 55° geometry allow use in both external and internal turning operations when paired with a compatible holder or boring bar.

How is the insert secured in the holder? The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for stable clamping; correct seating depends on matching form, relief angle and tolerance class.

What are the benefits of the NS9530 uncoated cermet grade? NS9530 delivers a sharp cutting edge, low cutting forces and high surface quality in finishing, reducing rework and improving surface consistency.

Can the DCMT070204 NS9530 be used for roughing applications? This grade and chipbreaker are optimised for finishing; for roughing, a tougher grade or different chipbreaker suited to higher depths of cut is recommended.
