DCMT 070204 NS9530 — Turning insert for finishing (Tungaloy)

The DCMT070204 NS9530 is an ISO rhombic turning insert designed for finishing operations in turning, offering a sharp cutting edge, low cutting forces and a focus on high surface quality.

• Uncoated cermet NS9530 finishing grade
• Sharp cutting edge for superior surface finish
• Rhombic 55° geometry with 7° clearance
• Cylindrical hole with single-side countersink

Achieve fine surfaces with lower cutting forces

The uncoated cermet composition of this grade delivers a sharp cutting edge that reduces friction and promotes continuous chip flow, which directly translates into low cutting forces and improved machining stability. Reduced forces mean less vibration and a more consistent tool path, resulting in a high surface finish on turned components. The insert’s construction supports small depths of cut and finishing passes where dimensional accuracy and visual quality are priorities.

Secure locating and straightforward holder compatibility

ISO-standard geometry and the rhombic shape with a 55° approach angle ensure the insert seats reliably in common external and internal holders. The cylindrical hole with single-side countersink (40°–60°) provides secure clamping and repeatable seating, while the 7° clearance protects the flank face during entry and exit. These design choices simplify tool changeover and reduce setup time, supporting consistent cycle times and fewer rejects in production.

Optimised grade for continuous finishing and small depths of cut

The NS9530 finishing grade is formulated for continuous cutting of Stahl where sharpness and low cutting forces are required. The combination of fine edge geometry and the insert’s nominal corner radius 0.4 mm makes it particularly suited to light-duty finishing and producing tight surface tolerances. In practice, this grade helps to maintain dimension with minimal burr formation, making it a cost-effective option for high-volume finishing or precision one-off components.

Practical benefits for workshop efficiency

Using an indexable insert with ISO conformity streamlines inventory and holder compatibility across different machines. The insert’s 2.38 mm thickness and compact 07 size balance rigidity and accessibility in confined setups. The single-side chipbreaker supports predictable chip formation in continuous cuts, reducing the need for secondary finishing and lowering overall processing time. Technical advisors can recommend the optimal holder and cutting parameters for specific workpiece materials and machine rigidity.

FAQ

What materials is this insert suitable for?
The NS9530 finishing grade is designed primarily for Stahl and is optimised for continuous finishing cuts where a sharp edge and low cutting forces are required; the DCMT070204 Tungaloy insert performs well in these conditions.

How should the insert be clamped in the holder?
Use a compatible ISO rhombic insert holder that accepts DCMT 07-sized plates; the cylindrical hole with a single-side countersink on the DCMT070204 ensures secure seating and repeatable clamping.

What is the corner radius and how does it affect finish?
The insert has a 0.4 mm corner radius, which supports fine surface finishes and accurate profiles during light finishing passes.

Can this insert be used for interrupted cuts?
The NS9530 grade is formulated for continuous cutting and fine finishing; for heavily interrupted cuts a more robust grade is recommended.
