CNMG120404 NS9530 CNMG turning insert for finishing by Tungaloy

A CNMG120404 NS9530 indexable turning insert designed for finishing operations in steel turning, compliant with ISO dimensions and suitable for use in standard rhombic holders

• ISO rhombic insert, 80° included angle
• Uncoated cermet for fine finishing
• Double-sided chipbreaker for uninterrupted cuts
• Cylindrical hole mounting, ISO holder compatible

Superior surface quality for finishing in steel

The NS9530 grade is an uncoated cermet developed for finishing applications in steel, delivering a sharp cutting edge with reduced cutting forces and improved surface quality. As a finishing insert, it performs best with small depths of cut and continuous machining, where the material's hardness and edge stability translate directly into measurable reductions in rework and polishing. The combination of the cermet substrate and the geometry produces a fine, predictable chip formation that helps maintain a consistent surface finish across batches.

Straightforward integration into ISO turning systems

Designed to the ISO series dimensions, the rhombic CNMG120404 geometry and the cylindrical mounting hole ensure compatibility with a wide range of external holders. The 80° included angle and 0° clearance support stable tool engagement while the 4.76 mm plate thickness and 0.4 mm nose radius provide a balance between stiffness and fine detail. Because holder compatibility depends on form, relief angle, tolerance class, fixing method, size and thickness, fitting this insert into existing tool systems is primarily a matter of matching those parameters, which simplifies setup and reduces downtime.

Reliable cutting behaviour and practical application advice

The insert features a double-sided chipbreaker, giving two useful cutting edges per index, and it is intended for continuous cutting where low cutting forces and reproducible chips are required. For optimal results, pair the insert with a holder and clamping set suited to the workpiece stability; select a chipbreaker and grade aligning with the work material and intended cut depth. The system concept comprises the ISO turning insert, a compatible external holder or boring bar, a backing/clamping set and replacement screws—keeping spare hardware on hand supports uninterrupted production.

FAQ

What materials is this insert suitable for? The CNMG120404 NS9530 Tungaloy turning insert is a finishing grade optimised for steel; its cermet composition and edge geometry make it particularly effective for achieving high surface quality on continuous cuts in steel.

Is the NS9530 grade coated? No, NS9530 is supplied as an uncoated cermet grade; the lack of coating contributes to the sharp cutting edge and low cutting forces expected in finishing operations.

How is the insert mounted in the toolholder? The insert uses a cylindrical hole for mounting and follows ISO dimensions; compatibility with holders is achieved by matching form, relief angle, tolerance class, fixing method, size and thickness.

Which cutting conditions suit this insert best? This insert is intended for finishing: small depths of cut, continuous machining and stable workholding deliver the best surface results while keeping cutting forces low.

Can the insert be indexed to use multiple edges? Yes, the double-sided chipbreaker provides multiple usable edges; the insert can be indexed according to the ISO geometry to exploit spare cutting corners.
