SNMG120404 NS9530 Tungaloy – ISO indexable turning insert, uncoated cermet for finishing

The SNMG120404 NS9530 Tungaloy is an ISO‑standard square turning insert intended for finishing operations on steel, offering a sharp cutting edge and optimised chip control for continuous cuts and small depths of cut.

• ISO SNMG 120404 geometry, 90° cutting angle
• Uncoated cermet NS9530 for fine finishing
• 0.4 mm corner radius for precise profiles
• Double-sided chipbreaker, cylindrical-holed insert

Achieve consistent fine finishes with a dedicated finishing grade

The NS9530 grade is an uncoated cermet developed as a finishing sort for steel, delivering a sharp cutting edge and low cutting forces. These properties reduce the tendency for built-up edge during continuous turning and help to achieve a superior surface finish with minimal secondary machining. By using a finishing‑oriented insert, process planners can expect more stable results at small depths of cut and reduced need for corrective passes, which supports predictable cycle times in series production.

Secure clamping and geometric compatibility for repeatable results

Compatibility with the toolholder is determined by the insert’s form, clearance angle, tolerance class, fastening method, size and thickness. The square ISO SNMG 120404 shape with a cylindrical hole provides reliable seating and repeatable positioning in appropriately matched external holders or boring bars. Specifying the correct holder geometry and tolerance class ensures that the 0° clearance and 4.76 mm plate thickness translate into consistent cutting engagement and predictable tool life over multiple insert changes.

Productivity gains via controlled chip formation and sharp edge life

The double‑sided chipbreaker design supports manageable chip control during continuous cutting, reducing the risk of entanglement and helping to maintain stable cutting forces. The combination of a cermet substrate and the insert’s geometry encourages fine, consistent chips and a clean exit at the cutting edge, which diminishes vibration and supports higher surface quality. For operations where repeatability and reduced rework are priorities, this indexable insert contributes directly to cycle‑time reliability and overall process efficiency.

Practical selection guidance for robust turning operations

When selecting an insert system for turning, choose the NS9530 finishing grade where fine surfaces and low cutting forces are required; pair the insert with a holder rated for the SNMG geometry and ensure correct clamping torque and seating. For small depths of cut and continuous feed conditions, the sharp edge and 0.4 mm corner radius are particularly advantageous for producing tight profiles without excessive feed marks. If uncertain about holder matches or cutting data, request a specification check to align insert geometry with machine rigidity and workpiece material.

FAQ

What workpiece materials is this grade best suited for?
The SNMG120404 NS9530 Tungaloy insert is a finishing sort for steel; the uncoated NS9530 cermet is optimised for continuous cuts and small depths of cut to produce high surface quality on steel components.

How does holder compatibility affect performance?
Compatibility is defined by insert form, clearance angle, tolerance class, fastening, size and thickness; using a correctly matched holder ensures the SNMG geometry seats properly and delivers repeatable cutting conditions.

Is the insert single‑use or indexable for multiple edges?
The insert is double‑sided with a double‑sided chipbreaker, allowing indexing of multiple cutting edges to extend productive life before replacement.

What edge geometry should be expected and when is it ideal?
The insert features a 0.4 mm corner radius, which is suitable for precise profiles and finishing operations where surface quality and dimensional control are priorities.

Does the SNMG120404 come with a coating?
This variant uses an uncoated cermet grade (NS9530), chosen for its sharp edge and low cutting forces in finishing applications on steel.
