• Sharp cutting edge for superior surface finish
• Double-sided chipbreaker for reliable chip control
• ISO SNMG120404 format, 90° square insert

Consistent finishing and reduced rework through low cutting forces

The NS9530 grade is an uncoated cermet developed for finishing steel with an emphasis on a sharp cutting edge and high surface finish. In practice this means lower cutting forces during continuous turning, which reduces vibration and the risk of workpiece distortion. The result is fewer re-machining cycles and a predictable component finish, making the insert particularly suited to applications where dimensional accuracy and surface integrity are critical. The combination of sharp geometry and cermet substrate promotes stable performance on small depths of cut.

Robust geometry and ISO compatibility for reliable tool setups

Built to the ISO SNMG120404 format, the insert features a 0.4 mm corner radius, 12 mm inscribed circle, and a plate thickness of 4.76 mm, with a 90° approach and 0° rake angle. The square form with a cylindrical hole ensures secure locating and straightforward clamping in standard holders. These dimensional standards facilitate rapid tool changes and reduce setup variation across machines. The double-sided chipbreaker extends usable edge life and maintains consistent chip control across repetitive production runs.

Practical guidance for maximised productivity and surface quality

For finishing tasks choose steady feeds and small depths of cut to exploit the cermet's edge stability; the built-in chipbreaker supports continuous machining and keeps swarf manageable. In a typical system the insert is used with a compatible external holder, a shim and clamping set, plus spare screws for maintenance. Selecting the correct chipbreaker and grade for the workpiece material will improve cycle times and reduce scrap. For repeatable results, match holder geometry and tolerance class to the insert form to ensure correct seat and clamping pressure for each cut; this delivers efficient, low-variation production.

FAQ

What operations is this insert intended for? The SNMG120404 NS9530 insert is designed primarily for finishing turning operations on steel, delivering a sharp edge and low cutting forces for high-quality surfaces.

Which holder types are compatible with the SNMG120404 format? Compatibility depends on holder form, radial relief, tolerance class, clamping method, size and thickness; use holders specified for ISO SNMG120404 inserts to ensure proper fit.

How does the NS9530 grade differ from coated carbide grades? NS9530 is an uncoated cermet grade optimised for sharp-edge finishing with low cutting forces, giving excellent surface quality in continuous cuts compared with typical coated carbide finishing grades.

Can the insert be used for roughing as well as finishing? The SNMG120404 NS9530 is optimised for finishing and small depth-of-cut applications; for roughing, a more robust grade and chipbreaker suited to higher feeds and interrupted cuts should be selected.

Are spare mounting components required for machine downtimes? A complete system includes an ISO insert, compatible external holder, shim/clamping set and spare screws; keeping spare consumables on hand reduces downtime and maintains productivity.
