Improve cycle efficiency with a finishing-grade cermet

This insert is designed as a finishing grade for turning operations where dimensional control and surface integrity matter. The uncoated cermet NS9530 provides a sharp, wear-resistant cutting edge that reduces cutting forces and heat generation, which in turn helps maintain machining stability during continuous cuts. The result is a measurable reduction in rework and improved throughput when finishing steel components. Because the geometry yields lower cutting resistance, tool life tends to be more predictable under stable process parameters.

Achieve consistent surface quality and dimensional fidelity

With a 0.2 mm corner radius and a 55° rhombic geometry, the cutting edge promotes a superior surface finish and repeatable part tolerances in fine-turning applications. The 7° clearance angle assists chip flow and minimises rubbing, so cutting action remains clean even at small depths of cut. For users with limited metrology expertise, the combination of these features means fewer trial-and-error adjustments and faster achievement of target Ra values on turned surfaces.

Clear compatibility rules and holder considerations

The insert conforms to ISO dimensions and mounts in standard DCGT-compatible holders; compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness. The plate thickness of 3.97 mm and the 11 mm inscribed circle must match the chosen clamp or screw system. The cylindrical hole with a single-sided countersink (40°–60°) ensures secure fastening and repeatable seating, which is essential for maintaining positional accuracy in production fixtures.

Recommended applications and material guidance

This grade is tailored for turning operations on steel where low cutting forces and high surface quality are priorities—especially continuous cutting with small depths of cut. The single-sided chipbreaker design supports controlled chip formation for uninterrupted runs. For best results select cutting parameters that favour finishing regimes: moderate feedrates, reduced depths of cut and stable speeds. Where multiple passes are required, the insert’s geometry and grade help preserve edge integrity across successive operations.

FAQ

What materials is this insert best suited for? This insert is optimised for turning steel in finishing operations; the NS9530 cermet grade promotes low cutting forces and fine surface finish when machining steel components.

Can the DCGT11T302 NS9530 be used for roughing operations? The DCGT11T302 NS9530 is a finishing-grade insert and is intended for continuous light cuts and small depths of cut; for heavy roughing, a tougher, coated grade would be more appropriate.

How does the 0.2 mm corner radius affect machining results? The 0.2 mm corner radius balances edge strength and surface finish, helping to produce smooth profiles while maintaining adequate edge life in finishing passes.

Is a specific holder required for ISO DCGT inserts? Compatibility requires a DCGT-compatible holder that matches the insert’s geometry, 7° clearance, thickness and fixing arrangement; the cylindrical hole with countersink ensures reliable seating in standard clamping systems.

Does the uncoated cermet require special cutting parameters? Uncoated cermet grades like NS9530 perform best with finishing parameters: moderate spindle speeds, reduced feed and shallow depths of cut to exploit the sharp edge and achieve optimal surface quality.
