EPGT 040104 NS9530 Turning Insert (ISO 040104) — Rhombic, 11° Clearance — Tungaloy

The EPGT040104 NS9530 is an ISO‑standard rhombic turning insert for external and internal turning, designed as a finishing grade for steels and optimised for continuous cuts and small depths of cut.

• Cermet finishing grade NS9530
• Rhombic ISO 04 format, 11° clearance
• 0.4 mm corner radius for fine finishes
• Cylindrical hole with single‑side countersink

Precision finishing with low cutting forces

The uncoated cermet grade NS9530 is engineered for finishing operations where surface quality and repeatable geometry matter. As a ceramic‑metal composite, cermet offers a sharp cutting edge and reduced adhesion to workpiece material, which results in lower cutting forces and diminished burr formation. For manufacturers performing continuous turning with small depths of cut, this grade helps to minimise rework and achieve consistent dimensional accuracy. The fine 0.4 mm corner radius supports delicate profiles and smooth transitions without compromising edge stability.

Seamless integration into ISO tool systems

Compatibility depends on several geometric and mechanical parameters; the insert conforms to the ISO 040104 designation and a rhombic plate shape, ensuring interchangeability with suitably rated holders. Key features such as 11° clearance, a thickness of 1.59 mm and the cylindrical hole with single‑side countersink (40°–60°) permit secure clamping and correct seating in both external holders and boring bars. When combined with the correct shim and clamping set, the system achieves reliable repeatability and avoids chatter that would otherwise degrade surface finish.

Productivity benefits and practical considerations

Selecting a finishing grade such as NS9530 reduces cutting forces and heat generation, which in turn prolongs tool life under light cutting conditions and reduces spindle load. The single‑side chipbreaker is tailored for continuous chips and helps to control evacuation at modest feeds; this supports safer, more predictable machining sequences. Practical assembly comprises the insert, a matched external holder or boring bar, the appropriate underlay/clamp set and replacement screws — a modular approach that simplifies maintenance and reduces downtime.

FAQ

What materials is this insert designed for?
The NS9530 finishing grade is specifically developed for machining steel; the EPGT 040104 insert from Tungaloy gives excellent surface quality when used in continuous turning of steel components.

Can the insert be used for both external and internal turning?
Yes, the rhombic ISO 040104 format and the 11° clearance make the insert suitable for both external turning and internal boring when paired with the appropriate holder.

How does the uncoated cermet grade affect tool life?
The uncoated cermet composition of the NS9530 insert promotes a sharp cutting edge and reduced adhesion, which helps maintain a stable edge for finishing tasks and can extend useful life under light cutting conditions.

What should be considered when selecting the holder?
Compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness; ensure the holder matches the ISO 040104 geometry and secures the insert with the correct shim and clamp set.

Is the insert suitable for interrupted cuts?
The NS9530 finishing grade is optimised for continuous cuts and small depths of cut; for heavily interrupted machining, a different grade or edge preparation is recommended.
