DCMT11T304 NS9530 Tungaloy turning insert (finishing grade, 0.4 mm radius)

DCMT11T304 NS9530 is an indexable turning insert for precision finishing operations in steel, designed for ISO-compatible holders and small depths of cut.

• ISO rhombic insert DCMT11T304 for turning
• Uncoated cermet NS9530 for fine finishing
• 0.4 mm corner radius, 7° clearance angle
• Central hole with cyl. recess and 40°–60° countersink

Precision finishing for demanding steel turning

The uncoated cermet NS9530 finishing grade provides a sharp, wear-resistant cutting edge tailored to steel finishing. With a 0.4 mm corner radius and 7° clearance, the geometry reduces cutting forces and supports continuous cuts, producing a finer surface finish with less burr and reduced secondary operations. Cermet grades are valued for edge stability and abrasion resistance at finishing speeds; this results in predictable tool life and consistent component quality in repeated runs.

ISO compatibility and secure clamping for fast setup

Designed to the ISO plate form, the rhombic geometry ensures broad compatibility with standard turning holders; fit is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The insert features a central hole with a cylindrical recess and a one-sided countersink (40°–60°), giving stable clamping and repeatable seating in the pocket. With a 3.97 mm thickness, the plate offers rigidity that helps suppress vibration, improving dimensional control and repeatable surface quality in both external and internal turning.

Reduced process costs through consistent results

Choosing a finishing-grade insert reduces rework and downstream polishing thanks to its chipbreaker geometry and sharp cutting edge that control chip flow and minimise heat build-up. The single-sided chipbreaker is matched to the grade for steel applications and is best used with small feed and depth settings to exploit the low cutting forces. Backed by Tungaloy’s production standards, this solution supports a stable, predictable process that lowers overall unit cost by reducing scrap and increasing first-pass quality.

FAQ

What materials is this insert suited for?
The DCMT11T304 NS9530 is specified as a finishing grade for steel; the cermet composition is optimised to deliver a fine surface when turning steel components.

Which clamping configuration does the insert require?
The insert has a central hole with a cylindrical recess and a one-sided countersink (40°–60°), suitable for standard ISO clamping screws and pockets that match the DCMT form.

What cutting conditions are recommended for best results?
Use the insert for finishing with small depths of cut and steady, continuous cuts; the NS9530 grade is engineered for low cutting forces and high surface quality in these conditions.

How does the NS9530 cermet improve component finish?
Cermet combines a hard, wear-resistant matrix with a sharp edge that resists deformation; NS9530 maintains edge integrity at finishing speeds, producing a smoother surface and extended time between interventions.

Is this insert suitable for internal turning as well as external turning?
Yes, the indexable geometry and secure central clamping make the insert appropriate for both external and internal turning operations when paired with a compatible ISO holder.
