SNGG 090304 NS9530 — ISO turning insert (90°, square) by Tungaloy

The SNGG090304-01 NS9530 Tungaloy insert is an ISO-format square turning insert designed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and superior surface quality

• ISO SNGG 090304 geometry for reliable clamping
• Uncoated cermet grade NS9530 for fine finishing
• 0° clearance and 90° approach for versatile turning
• Cylindrical hole for robust screw mounting

High-quality finishing for steel components

The uncoated cermet grade NS9530 is engineered as a finishing grade for steel, delivering a sharp cutting edge and low cutting forces that together produce an improved surface finish and reduced tendency for built-up edge. For continuous turning and small depths of cut the material composition of the grade helps to maintain stable cutting conditions and predictable wear behaviour. This makes the insert particularly suited to precision components where surface integrity and dimensional consistency are crucial. The result is fewer rework cycles and a more reliable production flow.

Secure mounting and broad ISO compatibility

The insert follows ISO indexing conventions and its compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness. The SNGG geometry with a 90° approach angle and a cylindrical hole ensures secure screw clamping in a matched external holder or boring bar. Key dimensions such as the 3.18 mm thickness and corner radius 0.4 mm support stable engagement in the pocket while allowing repeatable indexing. The supplied system normally comprises the ISO insert, a matched outer holder or boring bar, an underlayer/clamp set and replacement screws for straightforward assembly.

Improved process reliability and productivity

By combining a dedicated finishing grade with a square, indexable geometry, the insert reduces the need for multiple tool changes during finishing passes and contributes to shorter overall cycle times where fine tolerances are required. The continuous cut recommendation for this grade and the small depth-of-cut focus mean operators can expect consistent part-to-part results and fewer surface defects. Where surface quality is a primary KPI, using a specialised grade like NS9530 as part of a stable machine setup will deliver measurable quality gains while simplifying tool management.

Selection guidance and practical recommendations

Select the matching chipbreaker 01 and the finishing grade NS9530 for best results when turning steels in a continuous, low-feed regime. Verify holder compatibility by checking the pocket form, 0° clearance, tolerance class, fastening method and the insert thickness of 3.18 mm before use. The insert is uncoated, so it performs best in steady cutting conditions; for interrupted cuts or heavy roughing a different grade or geometry is recommended. Complement the insert with the correct shim/clamp set and torque the clamping screw to the holder manufacturer’s specification to secure repeatable performance.

FAQ

What is this insert best used for?
The SNGG090304-01 NS9530 insert is optimised for finishing steel in continuous turning operations, delivering low cutting forces and a high surface finish.

Which holders are compatible with this ISO insert?
Compatibility requires a holder that matches the SNGG geometry, 0° clearance, tolerance class, fastening type, size 09 and 3.18 mm thickness; use a matched external holder or boring bar with the appropriate shim/clamp set.

How is the insert secured in the pocket?
The insert uses a cylindrical hole for screw clamping; the combination of the hole and correct clamp/shim ensures stable, repeatable mounting when fastened to the specified torque.

Is the grade coated and what does that imply?
This is an uncoated cermet grade (NS9530), which provides a very sharp edge and is tailored to finishing; coated grades are typically preferred for roughing or when higher temperature resistance is required.

What are the key dimensions to check before ordering?
Check the geometry code 090304, approach angle 90°, thickness 3.18 mm, corner radius 0.4 mm, size 09, and the fact that it is an ISO-format square insert.
