SNMG120408 NS9530 SNMG turning indexable insert for finishing — Tungaloy

The SNMG120408 NS9530 indexable insert is designed for precision finishing of steel in external and internal turning, offering a sharp uncoated cermet grade for continuous cuts and fine surface results.

• SNMG form ISO 120408
• Uncoated cermet NS9530 for finishing
• 0.8 mm corner radius for fine surface
• Double-sided chipbreaker and cylindrical hole

High-precision finishing for steel with low cutting forces

The uncoated cermet grade NS9530 is engineered for finishing applications on steel, delivering a sharp cutting edge and reduced cutting forces that translate into consistent surface quality. Due to its composition, this grade is particularly suitable for continuous turning and small depths of cut where a superior finish and dimensional accuracy are required. The combination of a finely honed edge and cermet wear behaviour reduces the tendency for built-up edge, so machining cycles generate fewer rework operations and more predictable part quality.

ISO conformity and secure clamping to ensure process stability

As an ISO SNMG insert in the 120408 designation, compatibility with external holders and boring bars depends on form, clearance angle, tolerance class, fastening method, size and thickness. The square 12 mm form and the cylindrical hole provide reliable seat and positive clamping with common SNMG-capable holders. The 90° main geometry and a 0° clearance angle suit a wide range of turning set-ups; selecting a holder with appropriate rigidity and the specified clamping parts (shim and screw) minimises vibration and improves repeatability in batch production.

Optimised cycle times and consistent surface results through appropriate selection

The modest 0.8 mm corner radius balances edge strength and surface finish, making the insert well suited to fine finishing passes where tolerance and appearance matter. The double-sided chipbreaker allows economical indexing of two effective cutting edges, supporting higher productivity and lower tooling costs per part. For best results, match the chipbreaker and grade to the workpiece material, machining type and machine stability: this approach preserves edge life while maintaining the desired surface integrity and dimensional control.

FAQ

What materials is this insert intended for?
The SNMG120408 NS9530 insert is specified as a finishing grade for steel, offering an edge geometry and cermet behaviour optimised for continuous turning and fine surface finish.

How many cutting edges are available per insert?
With a double-sided chipbreaker and the square form, the insert allows indexing of multiple cutting edges to extend usable life before replacement.

Which holders are compatible with this ISO designation?
Holders and boring bars that accept ISO SNMG 120408 geometry and accommodate a 12 mm square plate, 4.76 mm thickness and cylindrical hole will be compatible; ensure holder rigidity and correct clamping components for stability.

Is the insert coated?
This grade is an uncoated cermet (NS9530), chosen for its sharp edge and finishing performance on steel in continuous-cut conditions.

What benefit does the 0.8 mm corner radius provide?
A 0.8 mm corner radius offers a balance between edge strength and the ability to produce fine surface finishes with controlled cutting forces in finishing passes.
