SNMG 120408 NS9530 Turning Insert by Tungaloy — uncoated cermet finishing grade, 90° geometry

The SNMG120408 NS9530 Tungaloy turning insert is an ISO-standard indexable insert designed for precise external and internal turning, optimised for finishing cuts on steel with low cutting forces

• SNMG 120408 NS9530 - uncoated cermet finishing grade
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker, cylindrical hole
• 0.8 mm corner radius, 90° insert geometry

Consistent finishing quality with low cutting forces

The NS9530 grade is an uncoated cermet developed as a finishing grade for steel, providing a sharp cutting edge that reduces cutting forces and promotes excellent surface finish on continuous cuts and small depths of cut. This results in more consistent part geometry and reduced need for secondary finishing, supporting efficient production cycles. The modest 0.8 mm corner radius balances edge strength with the ability to achieve fine surface textures, while the neutral clearance geometry aids stable contact during finishing passes.

ISO compatibility and reliable clamping for safe operation

Manufactured to ISO dimensions, the SNMG120408 form ensures predictable fitment in ISO holders; compatibility depends on insert form, clearance angle, tolerance class, fixing method, size and thickness. The insert features a cylindrical hole for secure screw mounting and a double-sided chipbreaker, enabling indexed use and economical cutting-edge utilisation. System components typically comprise the insert, a matching external holder or boring bar, a shim/clamp set and replacement screws — selected in accordance with the holder design to preserve the intended cutting geometry and tool life.

Application guidance to enhance productivity

This indexable insert is primarily intended for external and internal turning where finishing quality is the priority. The double-sided chipbreaker supports controlled chip formation on light to moderate feeds; choose the chipbreaker and grade to match workpiece material, machining strategy and machine-tool stability. For continuous cuts and small depths of cut the uncoated cermet excels at delivering consistent dimensional accuracy. For interrupted or heavy-duty conditions, select a more robust geometry or grade to maintain tool life and process reliability.
