SNMG 120404 NS9530 indexable insert for turning – Tungaloy

The SNMG120404 NS9530 is an ISO-indexed turning insert intended for finishing of steel, offering a sharp edge geometry and a chip control solution suited to continuous cutting and small depths of cut.

• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker for consistent chips
• ISO SNMG 120404, square 12 mm, cylindrical hole

Precise finishing performance for steel turning

The insert delivers a finishing-oriented performance thanks to the uncoated cermet composition of the NS9530 grade, which combines a very sharp cutting edge with wear resistance. This results in lower cutting forces and an improved surface quality on steel components when machining under continuous-cut conditions and with small radial depths of cut. The design is optimised for predictable tool life in finishing cycles, allowing process planners to rely on consistent part quality and reduced rework.

Designed for straightforward mounting and ISO compatibility

As an ISO‑standard indexable insert, the geometry and dimensions follow common holder requirements: SNMG 120404 denotes the form, while the insert is supplied with a cylindrical hole for secure clamping. The square 12 mm size and a plate thickness of 4.76 mm ensure mechanical stability in most external and internal turning holders that accept SNMG‑type plates. The corner radius 0.4 mm supports fine edge definition and contributes to the superior surface integrity achievable with this insert.

Operational advantages and recommended cutting conditions

The NS9530 grade is a finishing sort crafted for steels, showing its strengths at modest cutting depths and in uninterrupted cuts. The double-sided chipbreaker helps produce manageable chips and stable evacuation, reducing the risk of re-cutting or edge damage. Because the clearance angle is 0°, correct holder selection and set‑up are essential to achieve the intended shear conditions; once set up, the insert enables reliable, repeatable finishing with reduced force and demonstrable efficiency gains.

Productivity, process security and application scope

In production environments prioritising surface quality and cycle-time predictability, the insert supports high process stability and good surface finishes on a wide range of steels. The ISO conformity simplifies tool inventory and replacement procedures, making integration into existing tool systems straightforward. For tailored recommendations on feeds, speeds and holder compatibility, technical consultation is available to ensure the insert meets specific machining goals and machine constraints.

FAQ

What materials is this insert best suited for?
The SNMG120404 NS9530 insert is specified as a finishing grade for steels and performs particularly well in continuous cutting when low cutting forces and a high surface finish are required.

Is the insert reversible or indexable?
Yes, the SNMG 120404 is an indexable insert with multiple cutting edges; the double-sided chipbreaker allows reversal to a fresh edge to extend tool life.

Which holder type is required to use this insert?
An ISO-compatible turning holder designed for SNMG geometry with a cylindrical hole clamp and the correct seat for a square 12 mm insert is required for secure mounting and the intended cutting geometry.

What corner radius and thickness should be expected?
The insert has a corner radius of 0.4 mm and a plate thickness of 4.76 mm, dimensions that support fine finishing and stable cutting in turning operations.

Can the NS9530 grade be used for interrupted cuts?
The grade is optimised for continuous cutting and small depths of cut; interrupted cuts may reduce edge life and are not the primary intended application for NS9530.
