SNMG 120408 NS9530 Tungaloy turning insert — finishing grade for turning

A SNMG120408 NS9530 Tungaloy turning insert engineered for precision finishing of Stahl components in continuous cut conditions

• SNMG 120408 geometry for precision finishing
• Uncoated Cermet NS9530 with sharp cutting edge
• Double-sided chipbreaker for continuous cuts
• Square insert with r0.8 corner radius

High-precision finishing thanks to a cermet finish grade

The SNMG120408 is an ISO-standard turning insert designed as a finish grade for machining Stahl. Its uncoated cermet composition (NS9530) provides a consistently sharp cutting edge and low cutting forces, which together reduce vibration and promote excellent surface integrity. For operations with small depths of cut and continuous feeds, this combination translates into fewer secondary operations and reliable part tolerances. The form-fit and tolerance class align with conventional ISO holders, so integration into existing turning setups is straightforward.

Predictable chip control and edge behaviour for productive cycles

Equipped with a double-sided chipbreaker, the insert supports stable chip formation in steady cutting conditions, improving process repeatability and reducing risk of built-up edge. The uncoated cermet substrate retains a keen geometry that is particularly effective in producing mirror-like finishes on turned parts. This yields practical advantages in production: shorter cycle times due to less finishing, lower scrap rates, and a more consistent surface quality across batches. Where finishing standards are critical, the material combination and geometry work together to deliver measurable process reliability.

Compatibility and handling for workshop use

The insert is a square format with a corner radius of r0.8, a plate thickness of 4.76 mm and an included angle of 90°, paired with a cylindrical hole for secure clamping. The specified 0° relief ensures the intended cutting geometry when matched with the correct holder; compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness. The double-sided design allows a second indexing position, extending usable life per insert and simplifying inventory management. For best results, select the chipbreaker and grade according to the machine rigidity and workpiece stability.

FAQ

What applications suit this insert best?
The SNMG120408 NS9530 Tungaloy turning insert (SKU 6998195-Tungaloy) is intended for finishing operations in turning, especially continuous cuts and small depths of cut on Stahl where a sharp edge and low cutting forces are required.

Is the insert indexable and how many cutting edges are available?
Yes, the square geometry with a double-sided chipbreaker provides multiple usable edges; the design allows a second indexing position to extend service life before disposal.

Which holder features must be checked for compatibility?
Ensure the holder matches the ISO form, relief angle (0° specified), tolerance class, fastening method, plate size and thickness; these factors determine correct seating and cutting geometry.

Can the insert be used for interrupted cuts or roughing?
The NS9530 uncoated cermet is a finishing grade optimised for continuous cuts; for interrupted cuts or heavy roughing, choose a grade and chipbreaker tailored to higher impact and stability demands.

How does the uncoated cermet affect surface finish compared with coated grades?
Uncoated cermet grades like NS9530 preserve an exceptionally sharp cutting edge, which improves surface integrity during finish turning; coatings can benefit wear resistance but may blunt the initial edge for certain finish applications.
