SNMG 120408 NS9530 turning insert (ISO) by Tungaloy — finishing cermet, 0° relief

SNMG120408 NS9530 is an ISO-design turning insert intended for precision external and internal turning, optimised for finishing steel with continuous cuts

• SNMG120408 geometry for ISO turning
• Uncoated cermet NS9530 for fine finishing
• 0.8 mm corner radius for smooth surface

Achieve high-quality finishes with a dedicated cermet grade

The uncoated cermet grade NS9530 is designed specifically for finishing steel, offering a sharp cutting edge that reduces cutting forces and improves surface integrity. As a finishing grade, the material composition favours low built-up edge formation and consistent micro-geometry retention, which leads to fewer passes and less rework. The combination of the SNMG insert shape and the sharp edge makes this solution particularly suitable for continuous cuts and small depths of cut, delivering reliably high surface quality in production and toolroom environments.

Consistent compatibility and reliable clamping for stable turning

Compatibility with toolholders is determined by the insert’s form, relief angle, tolerance class, clamping method, size and thickness. This ISO-format square insert features a 0° relief angle, a nominal approach angle of 90°, and a 4.76 mm plate thickness, ensuring predictable seating in standard external holders and boring bars. The insert’s cylindrical hole and tolerance-compliant dimensions support secure clamping and repeatable positioning, which contributes to reduced vibration and improved process stability. Selecting holders and clamping kits that match these specifications ensures safe, repeatable operation on CNC lathes and manual turning centres.

Practical shopfloor advantages and recommended applications

Designed for external and internal turning, the SNMG geometry with a double-sided chipbreaker provides two usable cutting edges per index, increasing economy and uptime. For finishing operations on steel, the uncoated cermet reduces the need for frequent edge preparation and helps maintain a fine surface finish across series production. Given its characteristics, the insert is best applied where continuous cutting and small feed or depth parameters are required; choosing the correct chipbreaker and grade in line with workpiece rigidity and cutting parameters will deliver the intended productivity and surface quality benefits. For unusual materials or intermittent cuts, assessment of suitability is recommended to ensure optimal tool life.

FAQ

Is this insert suitable for finishing steel? Yes. The SNMG120408 in NS9530 is a finishing cermet grade specifically developed for finishing steel with low cutting forces and a sharp edge.

How many cutting edges are available per insert? The insert is double-sided with a double-sided chipbreaker, allowing two indexed cutting edges to be used for economical turning.

What holder compatibility should be observed? Compatibility depends on the insert form, relief angle, tolerance class, clamping and thickness; matching these parameters to the toolholder ensures correct seating and stable operation with the SNMG120408 NS9530 insert.

Can this insert be used for internal boring as well as external turning? Yes. The geometry and 90° approach angle permit both external and internal turning applications when combined with a suitable boring bar or holder.

What distinguishes the NS9530 grade from coated alternatives? NS9530 is an uncoated cermet finishing grade that maintains a sharp edge and reduces built-up edge during continuous cuts, offering superior surface finish for small depths of cut.
