CNMG120408 NS9530 Tungaloy insert — ISO indexable turning insert, 0.8 mm radius, 0° rake

CNMG120408 NS9530 Tungaloy insert designed for finish turning of steel components, offering a sharp cutting edge and stable performance in continuous cuts

ISO CNMG120408 form for standard holders Uncoated cermet grade NS9530 for fine finishes 0.8 mm corner radius for precise profiling Double-sided insert with cylindrical hole

Consistent surface finish for finish turning

The uncoated cermet grade NS9530 is specified for finish operations on steel where a sharp cutting edge and low cutting forces are required. In practical terms, this means more consistent part geometry and an improved surface quality after each pass. The combination of a small 0.8 mm corner radius and the CNMG geometry supports continuous cutting at small depths, which reduces vibration and helps achieve the targeted Ra values without aggressive machine settings.

Predictable fit and system compatibility

The insert conforms to ISO indexing standards, so compatibility with holders depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic shape and the presence of a cylindrical hole enable secure clamping in standard CNMG external holders or boring bars designed for ISO indexable inserts. This predictability in clamping reduces setup time and enhances process repeatability on production lines.

Grade and cutting-edge behaviour explained

The NS9530 designation denotes an uncoated cermet cutting material optimised for finishing steel. Cermet compositions combine ceramic hardness with metallic toughness, giving a sharp, wear-resistant edge that performs well under continuous cuts and small feed rates. As a result, the insert supports low cutting forces and produces a fine surface finish with minimal built-up edge, especially when machining medium-to-high-quality steel grades.

Operational benefits and typical use cases

With a 0° rake and a plate thickness of 4.76 mm, this insert provides a stable cutting geometry suited to external and internal turning when fine chip control is required. The double-sided chipbreaker extends usable life by allowing indexing to a fresh cutting edge. Typical applications include finish turning of shafts, journals and precision components where surface integrity and dimensional stability are priorities. Selecting matching chipbreaker and grade ensures efficient material removal with consistent outcomes.

FAQ

What applications suit this insert best?
The CNMG120408 NS9530 Tungaloy insert is intended for finish turning of steel components, especially where a sharp edge and low cutting forces are required for a fine surface finish.

Is the insert compatible with standard CNMG holders?
Compatibility follows ISO form and depends on clearance angle, tolerance class, fastening, size and thickness; the CNMG120408 form fits holders designed for CNMG inserts when those parameters match.

What is special about NS9530 cermet?
NS9530 is an uncoated cermet grade optimised for finishing: it offers a sharp edge, reduced cutting forces and good surface quality in continuous cuts.

How many useable cutting edges does the insert provide?
The insert is double-sided with indexing capability; each side provides fresh cutting edges according to CNMG geometry and positioning.
