DCMT070202 NS9530 — Tungaloy indexable turning insert for precision finishing, uncoated cermet, 0.2 mm radius

A DCMT070202 NS9530 indexable insert designed for precision turning and finishing operations on steel, offering a sharp cutting edge and stable performance in continuous cuts.

• Finishing-grade uncoated cermet NS9530
• Sharp cutting edge for low cutting forces
• Corner radius 0.2 mm for fine surface finish
• Cylindrical hole with single-sided countersink

Delivering consistent finishing performance for steel components

The insert was developed as a finishing grade for steel, combining an uncoated cermet substrate with a razor-sharp edge geometry to reduce cutting forces and improve surface quality. This results in stable cutting behaviour during continuous turning and small depths of cut, reducing the need for secondary operations. The controlled geometry and low built-up edge tendency help maintain dimensional accuracy and repeatable part quality across production batches.

Stable chip control and process reliability

Process stability is supported by the single-sided chipbreaker, which was selected to match finishing conditions and the typical feed range for small passes. The one-sided chip control promotes predictable chip formation and evacuation, minimising chatter and interruptions. For demanding finishing processes, the insert’s balanced design contributes to longer effective tool life and fewer adjustments during a production shift, which translates into higher productivity and lower overall machining costs.

Clear compatibility and simple system setup

Compatibility with holders is determined by the insert’s form, clearance angle, tolerance class, attachment method, size and thickness. The insert is an ISO-style component in size 07, with a thickness of 2.38 mm and a clearance/freey angle of 7°, combined with an approach/lead angle of 55°; these dimensions ensure correct seating and clamping in standard turning holders. The complete system comprises the insert, a matching external holder or boring bar, a backing/clip set and replacement screws for secure mounting and repeatable clamping.

Cermet advantages and operational benefits

The NS9530 cermet grade provides a hard, wear-resistant cutting edge that is optimised for low cutting forces and high surface finish in finishing operations. The combination of cemented carbide body and sharp-edge geometry reduces vibration sensitivity and supports continuous cuts with small depths of cut. For shops aiming to enhance surface quality and reduce downstream polishing or grinding, this insert offers a practical and economical route to improved part finish and consistent production results. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to suit common clamping systems.
