SPMR090304 NS9530 Tungaloy indexable insert for turning (finishing, 0.4 mm radius)

SPMR090304 NS9530 Tungaloy indexable insert is an ISO-standard square insert intended for precision finishing in turning applications

• ISO-standard square insert SPMR
• NS9530 uncoated cermet finishing grade
• 0.4 mm corner radius for fine surfaces
• 11° relief angle with single-sided chipbreaker

Precision finishing for turning operations that demand superior surfaces

The NS9530 grade is formulated as an uncoated cermet to provide a sharp cutting edge and reduced cutting forces, which together help achieve consistently fine surface finishes when performing continuous turning passes and small depths of cut. For operations where profile accuracy and finish are priorities, the combination of a 0.4 mm corner radius and the finishing geometry reduces burr formation and the need for secondary finishing, increasing process efficiency while maintaining component integrity.

Reliable ISO compatibility reduces setup time and integration risk

Being an ISO-standard insert, its compatibility with toolholders is determined by form, relief angle, tolerance class, clamping method, size and thickness. The square 09 format and the specified 11° relief angle mean straightforward selection of corresponding external holders or boring bars and standard clamping sets. The insert’s system concept—insert, holder, backing/clamp set and replacement screws—simplifies procurement and minimises downtime during tool changes, supporting a steady production flow and predictable tool change intervals.

Material and chip control designed for efficient finishing of Stahl

The cutting material is specified as an uncoated cermet grade (NS9530), delivering a balance between edge sharpness and wear resistance suited to finishing cuts in Stahl. The single-sided chipbreaker assists in producing controllable chips in continuous cut conditions, reducing chatter risk and improving surface consistency. Handling and storage are straightforward thanks to the robust geometry and defined mounting features; replacement inserts maintain repeatable results when clamped to the correct holder and torqued to specification.

FAQ

What cutting tasks is this insert best suited for?
The SPMR090304 NS9530 insert by Tungaloy is optimised for finishing turning operations, delivering low cutting forces and a high-quality surface on Stahl in continuous-cut conditions.

Which holders are compatible with this ISO insert?
Compatibility follows ISO form, relief and size standards; a matching square external holder or boring bar sized for 09 inserts with appropriate clamp and screw will accept the SPMR090304 insert.

Does the NS9530 grade require a coated insert for longer life?
The NS9530 uncoated cermet is designed for finishing and offers a sharp edge and good surface finish; in applications requiring increased wear resistance at higher temperatures, a coated grade may be considered instead.
