SNGG 120404 NS9530 indexable turning insert for turning, Tungaloy

The SNGG120404-01 NS9530 is an ISO-designated square indexable insert designed for precision finishing in turning applications, optimised for continuous cuts and minimal cutting forces.

• ISO square insert 12 mm size
• Finish grade NS9530 for steel
• 0.4 mm corner radius for fine finishes
• 0° relief angle, cylindrical hole

Precision finishing with a cermet cutting edge

The insert’s NS9530 cermet grade is formulated for finishing operations on steel, delivering a sharp cutting edge and reduced cutting forces that translate directly into improved surface quality and longer steady-state performance. Cermet materials combine ceramic hardness with metal toughness, enabling a consistent edge geometry suited to continuous cuts and small depths of cut. For manufacturers aiming to reduce rework and meet tight surface tolerances, this finish grade offers measurable advantages in process stability and part appearance.

Designed for reliable clamping and ISO-assisted compatibility

Produced as an ISO 120404 format, the square geometry and specified dimensions ensure predictable compatibility with standard external holders and boring bars when the holder’s form, clearance angle, tolerance class, fastening method, size and thickness match the insert. The insert features a cylindrical hole for positive location and a plate thickness of 4.76 mm, supporting secure clamping and repeatable positioning. Clear identification of these parameters simplifies tool assembly and minimises downtime during index changes.

Lower forces, better surfaces, less vibration

A small 0.4 mm corner radius and the sharp cermet edge reduce engagement forces and the tendency to build up material on the cutting edge, which in turn lowers the risk of chatter and improves surface finish. Choosing the matching chipbreaker (01) for this grade and adapting feeds and depths for finishing cuts helps to exploit the material’s strengths: consistent dimension control, excellent surface texture and efficient cycle times. These characteristics are particularly relevant for high-volume production where repeatability directly affects throughput and quality.

Practical selection and handling advice for series use

When integrating this insert into a production line, select a holder and fastening system compatible with the ISO form and the plate thickness to ensure correct seat and clearance. As an uncoated cermet finishing grade, the insert performs best under stable cutting conditions with continuous material flow; intermittent or heavily interrupted cuts may require a different grade. If there is uncertainty about suitability for a specific steel grade or machine rigidity, our team can advise on the optimal chipbreaker and operational parameters to achieve the required surface quality and tool life.

FAQ

What materials is this insert suitable for?
The NS9530 grade is designed primarily for steel finishing; the insert’s composition supports continuous cuts with low cutting forces for high-quality surface finishes.

What does the ISO designation 120404 indicate?
ISO 120404 defines the insert’s geometric series and size family; it helps to match the plate to compatible external holders and ensures consistent seat and clearance when assembling toolholders.

How is the insert secured in the holder?
The insert uses a cylindrical hole for positive location and is clamped by a compatible holder; compatibility depends on matching form, relief angle, tolerance class, fastening type, size and thickness.

Is the NS9530 grade coated?
No, NS9530 is supplied as an uncoated cermet finishing grade chosen for its sharp edge and low cutting forces in continuous finishing operations.

What corner radius does the insert have and why does it matter?
This insert has a 0.4 mm radius, which supports fine surface finishes and reduced cutting forces; a smaller radius helps achieve tighter surface tolerances in finishing cuts.
