SPMT090304 NS9530 – ISO turning insert, uncoated cermet (Tungaloy)

The SPMT090304 NS9530 is an ISO-format turning insert designed for external and internal finishing on steel, offering a sharp cutting edge and low cutting forces for continuous cuts.

Finishing-grade uncoated cermet NS9530
Low cutting forces for continuous cuts
0.4 mm corner radius for fine detail
Square ISO plate with cylindrical hole and countersink

Improved finishing with lower machining forces

The finishing-grade NS9530 uncoated cermet is optimised for low cutting forces and a sharp cutting edge, which together produce a consistently high surface finish on steel components. The combination of a small 0.4 mm corner radius and a precise cutting geometry reduces the need for secondary grinding or polishing, lowering cycle times and overall manufacturing costs. This makes the insert particularly suitable where continuous cuts and small depths of cut are routine.

Designed for secure clamping and straightforward integration

As an ISO-format plate, the insert fits standard holders when form, relief angle, tolerance class, fastening method, size and thickness are matched. The plate is square (size 09) with a 3.18 mm plate thickness, a 11° relief angle and a central hole with a cylindrical bore plus a one-sided countersink (40°–60°), enabling stable seating and repeatable clamping. The 90° cutting angle and standardised dimensions simplify tool inventory and reduce setup time when changing tools within a production line.

Material range and reliable process performance

The insert combines a carbide body and an uncoated cermet cutting material, giving a balance of wear resistance and edge acuity for finishing operations on steel. The single-sided chipbreaker is tailored for chip control in stable turning conditions, improving surface integrity and process repeatability. Typical uses include external and internal turning where a fine finish and gentle cutting action are required, delivering predictable results and reduced scrap rates.
