SNMG120402 NS9530 ISO turning insert — uncoated cermet, 90° square by Tungaloy

A SNMG120402 NS9530 ISO-standard turning insert designed for precision finishing of steel components with a sharp cutting edge and stable chip control

• Precision finishing for steel
• Uncoated cermet for superior surface finish
• ISO‑standard SNMG 120402 geometry
• Double‑sided chipbreaker for stability
• Cylindrical hole for secure clamping

Consistent finishing with low cutting forces

The grade is an uncoated cermet developed for finishing passes on steel where low cutting forces and excellent surface quality are required. Cermet combines ceramic and metallic phases to provide a hard, wear-resistant cutting edge that maintains sharpness during continuous cuts. For turning operations where small depths of cut and fine feeds are common, this insert minimises edge deformation, reduces vibration and helps achieve repeatable micro‑roughness values. The result is improved process stability and less downstream polishing or reworking.

ISO geometry for secure clamping and repeatable set‑ups

The SNMG form follows ISO‑standard geometry for a square, 90° insert, giving a robust seating and straightforward indexability. The cylindrical hole and specified tolerances ensure secure fastening in compatible holders; compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness. With a 4.76 mm plate thickness and 12 mm inscribed size, the insert fits common external holders and boring bars, enabling rapid index changes and consistent tool offsets for productive shopfloor workflows.

Improved chip control and surface integrity for continuous passes

A double‑sided chipbreaker tailored to finishing promotes stable chip formation during uninterrupted cuts, which is particularly advantageous when producing long turned lengths or high-volume batches. The selected grade, optimised for fine feeds, supports a 0.2 mm corner radius that balances edge strength with the ability to produce tight dimensional tolerances and high-quality finishes. This combination reduces built-up edge tendencies and helps maintain cycle times by lowering the need for secondary operations.

Practical system considerations and shop benefits

Use this insert as part of a standard ISO insert system comprising the insert itself, a matching external or boring holder, a shim/clamp set and the correct fastening screw. Selecting the appropriate chipbreaker and grade according to the workpiece material and cutting conditions ensures favourable tool life and consistent results. For CNC turning shops focused on finishing operations, this solution contributes to predictable set‑up times, reduced scrap and a better rate of first‑pass acceptance, supporting both efficiency and quality objectives.
