DCMT070204 NS9530 Turning insert by Tungaloy — uncoated cermet finishing grade

DCMT070204 NS9530 is a rhombic ISO turning insert optimised for fine finishing of steel components in both external and internal turning applications.

• ISO rhombic DCMT form for universal turning
• Uncoated cermet NS9530 for fine finishing
• Low cutting forces for vibration control
• Cylindrical hole with 40°–60° countersink

Achieve superior surface quality with a finishing-grade cutting edge

The NS9530 specification denotes an uncoated cermet designed specifically as a finishing grade for steel, offering a sharp cutting edge and reduced cutting forces. This composition produces a finer microgeometry on the insert edge than standard carbide grades, which directly improves the surface finish on the workpiece and lowers the energy required per cut. For continuous cutting and small depths of cut the result is a noticeable reduction in chatter and a more consistent part-to-part surface quality, making this insert suitable where tight finish tolerances are required.

Predictable setup and secure clamping for repeatable turning

Shaped to the ISO rhombic geometry, the insert’s form and dimensions ensure compatibility with standard holders when the seat, tolerance class and fastening match the plate size and thickness. The ISO-standard geometry simplifies tool selection and reduces setup time on the machine. Key geometric values such as the 7° relief, 0.4 mm corner radius and 2.38 mm thickness influence cutting behaviour: the relief angle controls flank contact, the corner radius defines profile rounding and the thickness adds rigidity in the clamped state, all contributing to stable clamping and repeatable tool life under comparable cutting conditions.

Practical application guidance and process benefits

Designed for turning of steel, this insert features a single-sided chipbreaker that is best suited to continuous cuts and small feeds where a fine, regular chip is desirable. The rhombic plate with a cylindrical hole and one-sided countersink (40°–60°) provides reliable location and positive clamping in compatible toolholders. Choosing this grade and chipbreaker combination helps to reduce secondary operations by delivering acceptable finish right off the lathe and to extend the intervals between index changes, improving overall process throughput without compromising component quality.

FAQ

What materials is this insert intended for?
The DCMT070204 NS9530 insert is specified as a finishing-grade for steel; the NS9530 composition targets improved surface finish and low cutting forces when turning steel components.

Can this insert be used in standard ISO holders?
Yes, the insert follows ISO rhombic geometry; compatibility with a holder depends on matching form, relief angle, tolerance class, fastening method, size and thickness.

Which cutting conditions suit the NS9530 grade best?
NS9530 performs best in continuous cutting operations with small depths of cut and moderate feeds, where a sharp edge and low cutting force deliver the desired surface quality.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert produces regular, controllable chips in finishing cuts, aiding chip evacuation and reducing the risk of workpiece surface damage.

Is the insert suitable for internal turning as well as external turning?
Yes, the geometry and thin profile of the rhombic DCMT insert make it appropriate for both external and internal turning tasks when used with a compatible holder.
