DCMT070202 NS9530 ISO turning insert by Tungaloy — uncoated cermet, 0.2 mm nose radius

DCMT070202 NS9530 is an indexable insert for finishing operations in turning, optimised for continuous cuts and small depths of cut

• Precision finishing for steel with uncoated cermet
• Low cutting forces and superior surface finish
• ISO rhombic shape 07 with 0.2 mm corner radius
• Cylindrical hole with 40°–60° countersink design

Optimised finishing performance for steel turning

The NS9530 grade is an uncoated cermet developed for fine finishing of steel, delivering a sharp cutting edge with reduced cutting forces and an improved surface result. As a finishing variety, this insert is particularly suitable for continuous cut conditions and small depths of cut where stability and surface integrity are decisive. The combination of a cermet substrate and keen geometry reduces built-in vibration and supports repeatable part quality, making it a reliable choice when consistent surface finish and dimensional control matter.

Geometry and clamping designed for production reliability

The insert’s ISO rhombic 07 form with a 0.2 mm corner radius and 55° included angle provides predictable engagement and toolpath clearance in typical turning set-ups. The 7° relief angle and a plate thickness of 2.38 mm contribute to a stable cutting edge, while the cylindrical hole with a countersink (40°–60°) ensures secure seating and repeatable clamping. Holder compatibility is defined by form, relief angle, tolerance class, fastening method, size and thickness; these factors determine correct seating and accurate repeatability in production toolholders.

Practical application guidance and machining benefits

Intended for external and internal turning, the insert is best applied as a finishing tool where fine surface quality is required. The single-sided chipbreaker promotes controlled chip formation under continuous cutting, which assists in maintaining consistent surface integrity. For cost-effective machining, select the NS9530 grade and a chipbreaker matched to the workpiece material and process stability; when used in appropriate feeds and depths, the insert supports reduced hand-finishing and shorter downstream processing. Compatibility with industry-standard ISO holders allows straightforward integration into existing tool systems and quick replacement during planned tool changes.

FAQ

What kind of operations is this insert designed for?
The DCMT070202 NS9530 Tungaloy turning insert is intended for finishing operations in turning, especially continuous cuts and small depths of cut to achieve improved surface finish.

Is this insert suitable for internal as well as external turning?
Yes. The geometry and rhombic 07 form make the insert suitable for both external and internal turning when paired with compatible ISO holders.

Which workpiece materials does the NS9530 grade target most effectively?
NS9530 is a finishing grade optimised for steel; the uncoated cermet substrate provides a sharp edge and low cutting forces for high surface quality.

How does the hole and countersink design affect clamping?
The cylindrical hole with a 40°–60° countersink ensures consistent seating and secure clamping in standard toolholders, aiding repeatability during index changes.

Can the insert be integrated into existing toolholder systems?
Yes; the ISO designation and standardised dimensions allow integration into holders that match the form, relief angle, tolerance class, fastening and thickness.
