EPGT 040102 NS9530 turning insert (finishing) — Tungaloy

The EPGT 040102 NS9530 is an ISO rhombic turning insert intended for finishing cuts on steel components, offering a sharp cutting edge and low cutting forces for continuous turning operations.

• ISO rhombic insert size 04
• NS9530 uncoated cermet finishing grade
• Sharp edge for low cutting forces
• Cylindrical hole with 40°–60° countersink

Precision finishing for steel components

The insert is a finishing grade based on NS9530 and an uncoated cermet substrate, designed to deliver a high surface finish with reduced cutting forces. The sharp edge geometry minimises deformation at the cut, which supports consistent dimensional accuracy on turned shafts and collars. For continuous cuts and small depths of cut, this configuration reduces rework and enhances throughput.

Stable cutting performance and predictable chips

A single-sided chipbreaker and optimised edge form promote controlled chip formation during standard turning operations. The chip control reduces material buildup on the cutting edge and lowers vibration potential, which in turn preserves tool life and workpiece integrity. These effects yield a measurable improvement in process stability and repeatability for production environments.

Easy integration into ISO tool systems

Conforming to ISO insert standards, the rhombic size 04 geometry and the cylindrical hole with single-side countersink (40°–60°) ensure compatibility with common external holders and boring bars. The insert’s 11° relief angle and 75° included angle are key parameters for selecting a suitable seat and clamp; compatibility depends on form, tolerance class, fastening method, size and thickness of the toolholder.

Practical handling and recommended use

With a corner radius of 0.2 mm and a plate thickness of 1.59 mm, this insert is optimised for fine finishing passes and small stepovers. It is primarily intended for turning steel where smooth surfaces and low cutting resistance are priorities. For interrupted cuts or heavy roughing, choose a grade and geometry designed for shock resistance; for continuous finishing, this insert offers a cost-effective balance of quality and productivity.

FAQ

What is the primary application for this insert?
The EPGT 040102 NS9530 insert is intended for turning applications, specifically finishing steel components where a fine surface and low cutting forces are required.

Which materials does this grade suit best?
The NS9530 uncoated cermet grade is optimised for steel finishing; it performs well in continuous cut conditions and with small depths of cut.

How does the chip control work with this geometry?
The single-sided chipbreaker on the EPGT 040102 promotes consistent chip formation, reducing edge build-up and improving process stability.

Is this insert compatible with standard ISO holders?
Yes — the ISO-compliant rhombic form, size 04, and the hole with countersink are designed for compatibility; selection of the correct holder depends on form, relief, tolerance class and fastening method.
