SNMG 120404 AT9530 Tungaloy turning insert — square, 0.4 mm corner radius

The SNMG120404 AT9530 Tungaloy indexable insert is an ISO‑standard square turning insert designed for fine and light finishing of steel components.

• SNMG geometry, ISO 120404 compatible
• AT9530 coated cermet for fine finishing
• Double-sided chipbreaker for reliable chips
• Square plate with 0.4 mm corner radius

Optimised finishing for consistent surface quality

The SNMG‑style indexable insert is engineered to deliver a superior surface finish in finishing applications. The AT9530 coated cermet grade prioritises even wear and low built‑up edge formation, which translates into fewer interruptions for tool changes and more consistent part quality. For operators transitioning from general‑purpose grades, the coating and substrate combination reduces edge degradation during low‑depth finishing cuts, meaning fewer rejects and less rework.

Predictable geometry and secure clamping for process reliability

With an ISO‑conforming square form and a 0.4 mm corner radius, this insert supports reliable toolpath programming and reproducible results across batches. The carbide substrate provides the rigidity required for steady cutting at fine feeds, while the cylindrical hole and matching clamping system ensure stable seating in standard external holders. These characteristics reduce vibration and promote dimensional stability, which benefits shops seeking to tighten tolerances without complex machine adjustments.

Practical chip control and efficient machining

Equipped with a double-sided chipbreaker, the insert manages chip formation effectively during light turning operations. Controlled chip formation improves operator safety and reduces the likelihood of workpiece surface damage from errant swarf. Because the geometry permits re‑indexing, the insert offers two usable cutting edges, supporting economical machining runs and lower tooling consumption in finishing cycles.

Application guidance and system compatibility

Designed for external and internal turning of steel, the insert integrates into standard ISO tool systems. Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; matching the insert to an appropriate external holder or boring bar is therefore essential for optimum performance. The system typically comprises the ISO indexable insert, a suitable external holder or boring bar, a seat/clamp set and replacement screws, enabling straightforward replacement and minimal downtime.

FAQ

What materials is this insert best suited for?
The SNMG120404 AT9530 Tungaloy indexable insert is optimised for finishing and light machining of steel, offering good surface quality and uniform wear with the AT9530 cermet grade.

Can the insert be re‑indexed to use multiple cutting edges?
Yes, the square SNMG geometry allows re‑indexing; the double‑sided chipbreaker provides two usable edges per index for economical machining.

Which holder types are compatible with this insert?
Compatibility depends on holder form, clearance angle and fastening method; the insert fits standard ISO external holders or boring bars that accept SNMG‑style plates.

Does the AT9530 grade require special cutting parameters?
The AT9530 coated cermet grade performs best in finishing and light cuts; using conservative feeds and optimised cutting speeds for cermet will prolong tool life and maintain surface quality.

What are the measurable dimensions to check before ordering?
Verify ISO designation (120404), plate size (12 mm), plate thickness (4.76 mm), corner radius (0.4 mm) and the presence of a cylindrical hole to ensure correct fit.
