SNMG 120404 NS9530 – indexable insert for turning (Tungaloy)

SNMG120404 NS9530 is an ISO‑form indexable insert designed for precision finishing in turning operations on steel.

• Uncoated cermet for fine finishing
• Sharp cutting edge; low cutting forces
• ISO SNMG form with 0.4 mm corner radius
• Double-sided chipbreaker, with cylindrical hole

High-quality finishing with low cutting forces

The uncoated cermet grade NS9530 delivers a consistently fine surface on steel components by combining a keen cutting edge with thermal stability during continuous cuts. Its formulation reduces built-up edge and maintains a sharp profile, which results in lower cutting forces and improved surface integrity. For finishing passes and small depths of cut, this insert offers measurable gains in productivity and part quality compared with conventional grades, while permitting higher feed stability in long runs.

Precise geometry and secure clamping for repeatable results

The ISO SNMG geometry with a 0.4 mm corner radius and a square plate form provides predictable chip flow and dimensional control. The insert is double‑sided and features a cylindrical hole for accurate locating and secure clamping in compatible holders; compatibility is determined by form, relief angle, tolerance class, attachment and thickness. These attributes reduce vibration and tool movement, which lowers rework rates and extends effective tool life through consistent edge engagement.

Application guidance and selection advantages

Designed primarily for turning, the grade is particularly suited to continuous cuts and small uncut chip thicknesses where surface finish is critical. The combination of a sharp cutting edge and cermet chemistry supports finishing on a wide range of steels when using the appropriate holder and cutting parameters. When selecting the holder and cutting data, consider rigidity and feed rate to exploit the insert’s capacity for good surface quality and low cutting forces; matching the chipbreaker and grade to the workpiece material and machining method yields the best economy and process stability.

FAQ

What holder types are compatible with this SNMG insert?
Compatibility depends on holder form, relief angle, tolerance class, attachment method, size and thickness; the SNMG120404 insert fits standard SNMG external turning toolholders used for ISO SNMG inserts.

Is the NS9530 grade suitable for finishing steel?
Yes, the NS9530 uncoated cermet is formulated for finishing steel with a sharp cutting edge and low cutting forces, delivering high surface quality in continuous cutting conditions.

Can the insert be used on interrupted cuts?
The grade is optimised for continuous cuts and small depths of cut; for heavy interruption or unstable setups, a more robust grade or different chipbreaker may be preferable.

How does the 0.4 mm corner radius affect part quality?
A 0.4 mm corner radius improves edge strength while maintaining the capacity for fine surface finishes; it balances durability and precision for finishing passes.
