SNMG120408 NS9530 indexable turning insert — uncoated cermet, 0.8 mm radius — Tungaloy

The SNMG120408 NS9530 is an ISO‑standard indexable insert designed for fine finishing in external and internal turning, offering a sharp cutting edge and predictable chip control for steel machining

• SNMG 120408 geometry for standard ISO holders
• NS9530 cermet for superior surface finish
• Double‑sided chipbreaker for extended life

Achieve superior surface finish with low cutting forces

The uncoated cermet grade NS9530 is formulated for finishing applications where a sharp cutting edge and minimal cutting forces produce smoother component surfaces. Cermet combines ceramic hardness with metallic toughness, which reduces built‑up edge and improves consistency on continuous cuts and small depths of cut. For machining steel, this results in reduced vibration and improved dimensional control, so machined parts meet tight surface‑quality demands without excessive tool pressure.

Secure fit and ISO compatibility for predictable performance

The ISO SNMG120408 geometry and square plate form deliver broad compatibility with standard indexable turning holders. Key mechanical dimensions such as the 12 mm plate size, 4.76 mm thickness and a 90° included angle ensure predictable seating and clamping. Compatibility is determined by form, relief angle, tolerance class, fastening and plate thickness; selecting a matching holder and correct clamping torque reduces runout and preserves the insert’s sharp cutting edge, supporting repeatable production cycles.

Stable chip control and process reliability

A double‑sided chipbreaker provides effective chip formation for finishing cuts, creating short, controllable chips that improve machine safety and surface quality. The uncoated nature of the grade makes it especially suited to continuous cutting at light depths of cut, where thermal stability and a sharp edge matter most. Choosing the appropriate chipbreaker and grade according to workpiece stability and machining strategy enhances tool life and lowers the risk of interrupted cuts, contributing to steady production throughput.
