EPGT040102 NS9530 Tungaloy turning insert – rhombic 04, 11° relief

The EPGT040102 NS9530 is an ISO-format rhombic turning insert designed for finishing steel with a sharp cutting edge and optimised low cutting forces for continuous, light-turning operations

• NS9530 uncoated cermet for finishing
• Sharp edge for superior surface finish
• Rhombic 04 form with 11° relief
• Suitable for continuous light cuts

Higher-quality finishing with reduced cutting forces

The uncoated NS9530 cermet grade is formulated for finishing of steel, providing a sharp cutting edge that lowers cutting forces and helps secure a consistently fine surface texture. As a finishing grade, it is intended for continuous cuts and small depths of cut, which reduces vibration and contributes to predictable results. The result is improved part consistency and fewer rework cycles, translating into greater process efficiency and time savings on high-volume finishing tasks.

Stable insert geometry for repeatable tool performance

The rhombic 04 geometry, combined with an 11° relief and a 0.2 mm corner radius, supports controlled chip formation and fine surface outcomes. The insert presents an included angle of 75°, a plate thickness of 1.59 mm and a secure mounting option with a cylindrical hole and single-side countersink (40°–60°), ensuring repeatable clamping and alignment. Compatibility with the toolholder is determined by form, relief angle, tolerance class, fastening method, size and thickness, so matching the insert to a compatible holder preserves cutting stability and repeatability.

Application guidance and system-level benefits

Designed as part of an ISO turning system, the insert is used together with an appropriate outer holder or boring bar, a suitable shim or clamp set and replacement screws. For practical use, select the single-sided chipbreaker and the grade NS9530 for finishing operations on steel where low cutting forces and superior surface finish are priorities. The combination of uncoated cermet and optimised geometry reduces built-up edge tendency during low-depth continuous turning, supporting longer effective tool life and steady component quality.

FAQ

What materials is this insert suited for?
The NS9530 grade is formulated for finishing on steel; the EPGT040102 insert delivers low cutting forces and a fine surface when used for light continuous turning of steel components.

Which operations are appropriate for this insert?
This insert is designed for external and internal turning where finishing passes and small depths of cut are required, especially continuous, vibration-free machining.

How is holder compatibility determined?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; the EPGT040102 must match the holder's specifications for correct clamping and alignment.

What effect does the 0.2 mm corner radius have?
A 0.2 mm radius supports a fine surface finish while keeping cutting forces low, making it suitable for precise finishing passes with minimal tool-induced distortion.

Is the insert coated?
The NS9530 variant is an uncoated cermet finishing grade, optimised for sharp edge performance and high surface quality on steel
