EPGT040104 040104 NS9530 Tungaloy indexable turning insert — rhombic 75°

The EPGT040104 NS9530 is an ISO‑standard rhombic indexable insert designed for precision turning and finishing of steel components.

• ISO‑standard rhombic insert, 75° geometry
• Uncoated cermet NS9530 for high surface finish
• Single‑sided chipbreaker for continuous cuts
• 0.4 mm corner radius for precise profiling

Precision finishing enabled by cermet technology

The uncoated cermet NS9530 grade delivers a sharp cutting edge with low cutting forces, making it particularly effective for finishing passes on steel where surface quality is critical. Cermet combines ceramic hardness with metallic toughness, which means improved wear resistance and consistent surface finish during continuous cuts and small depth‑of‑cut operations. The ISO conformity ensures predictable seating and repeatable results across standard holders, reducing setup time and the need for trial adjustments.

Geometry that secures consistent profiles and accuracy

The rhombic 75° geometry and 0.4 mm corner radius provide controlled engagement and accurate profile transfer, especially for fine contour work and small radii features. The insert’s 11° clearance angle supports stable cutting conditions and limits rubbing on the flank, while the modest thickness contributes to reliable clamping in the seat. These geometric choices translate into fewer reworks and a steady part finish when used as a finishing grade in turning operations.

Easy integration into existing turning systems

The insert is supplied as an ISO‑standard indexable plate and fits into a system comprising a matching external holder or boring bar, an underlay/clamping set and replacement screws. The component is designed with a cylindrical hole plus a one‑sided countersink (40°–60°) for secure fastening. Selection of the chipbreaker and grade should match the workpiece material, machining style and machine stability; this grade is optimised for continuous cuts and small feeds. For application or compatibility checks, Metav Werkzeuge provides technical advice and detailed data to ensure the insert integrates smoothly with the chosen tooling system.

FAQ

Which materials is this insert suitable for?
The EPGT040104 NS9530 insert is specified as a finishing grade for steel and performs best on continuous cuts and small depth‑of‑cut finishing operations.

Can this insert be used for internal turning operations?
Yes — the insert is suitable for both external and internal turning when mounted in an appropriate boring bar or holder that accepts ISO‑standard rhombic plates.

How is holder compatibility ensured?
Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and plate thickness; the EPGT040104 conforms to ISO dimensions to simplify matching with standard external holders and boring bars.

Is the cutting material coated?
No — this grade is an uncoated cermet (NS9530) designed to offer a sharp edge and superior surface finish for finishing passes.

What benefits does the 0.4 mm corner radius provide?
A 0.4 mm corner radius improves profile control and helps achieve repeatable part geometry while limiting cutting forces during fine finishing.
