DCMT070204 NS9530 Tungaloy indexable insert — uncoated cermet finishing grade

A DCMT070204 NS9530 Tungaloy indexable insert designed for finishing turning on steel, offering a rhombic 55° geometry and a 0.4 mm nose radius for superior surface finish

• Uncoated cermet NS9530 for finishing
• Sharp cutting edge, low cutting forces
• Rhombic 55° geometry, 0.4 mm nose radius
• ISO-series insert, cylindrical hole with countersink

Precision finishing with an uncoated cermet for steel components

The uncoated cermet NS9530 is engineered as a finishing grade for turning steel, combining a finely honed cutting edge with material properties that reduce edge deformation. This results in lower cutting forces and consistently improved surface finish on continuous cuts and small depths of cut. Cermet comprises a mix of ceramic and metallic phases that offers high wear resistance and thermal stability; in an uncoated form it promotes excellent initial sharpness, which is particularly beneficial for delicate finishing passes where surface integrity is critical.

Predictable clamping and easy integration into ISO turning systems

Designed to the ISO DCMT070204 form, the insert features a rhombic 55° profile and a 0.4 mm nose radius, with a plate thickness of 2.38 mm and a cylindrical hole plus single-sided countersink (40°–60°). Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening and plate dimensions; the ISO conformity ensures reliable seating and repeatable indexing in suitable external holders or boring bars. The one-sided chipbreaker and standard hole format simplify toolroom stocking and reduce setup deviations, supporting steady cycle times and predictable tool performance.

Process stability and application advantages in turning

When employed for external and internal turning, the insert’s sharp edge geometry and cermet substrate produce a fine surface texture while keeping cutting forces low, which in turn reduces vibration and improves dimensional stability of the workpiece. The single-sided chipbreaker promotes controlled chip formation for finishing feeds, and the insert’s design suits stable turning conditions with small depths of cut. For applications requiring consistent surface quality and tight tolerances, this insert provides an economical route to improved part finish without additional machining steps.

FAQ

What materials is this insert intended for? The DCMT070204 NS9530 insert is specified as a finishing grade for steel, using an uncoated cermet structure to achieve high surface quality.

Is the insert compatible with ISO turning holders? Yes, the DCMT070204 form is ISO-standardised; compatibility depends on matching form, clearance angle (7°), tolerance class, fastening and thickness in the chosen holder.

Which machining conditions suit the NS9530 grade best? The NS9530 grade is optimised for continuous cutting and small depths of cut, where a sharp edge and low cutting forces deliver superior surface finishes.

How does the 0.4 mm radius affect part quality? A 0.4 mm nose radius balances edge strength with fine surface generation, helping to produce accurate profiles and improved roughness values on finishing passes.

Does the insert offer controlled chip formation? The single-sided chipbreaker on this insert promotes controlled chip flow for finishing feeds, improving surface consistency during turning operations.
