SNGG 120408 NS9530 — Indexable turning insert (square, with hole) by Tungaloy

The SNGG120408-01 NS9530 is an ISO-standard square indexable insert designed for external and internal turning, offering a finishing cermet grade for low cutting forces and superior surface quality.

• ISO square insert, 12 mm size
• Uncoated cermet NS9530 finishing grade
• 0° rake angle and 0.8 mm corner radius
• Cylindrical hole for secure clamp mounting

Achieve consistently finer surfaces with a finishing cermet

The choice of an uncoated cermet grade such as NS9530 yields a sharp cutting edge and reduced built-up edge during continuous turning of steel, which translates into high surface finish and lower secondary operations. The material behaviour of cermet promotes small, regular chips and low cutting forces; this is especially valuable for small depths of cut and finishing passes where dimensional accuracy and surface integrity are decisive. Selecting a finishing grade aligned to the workpiece material reduces rework and contributes to predictable cycle times.

Compatibility and secure clamping reduce setup variability

The insert follows ISO-standard geometry, so compatibility with clamping systems is governed by form, clearance, tolerance class, fastening and thickness. The square shape with a cylindrical hole provides repeatable seating and stable location under radial loading, improving toolholder rigidity. With a nominal 12 mm size and a plate thickness of 4.76 mm, the insert suits standard external holders and boring bars designed for ISO SNGG types. The consistent interface and secure fixing reduce vibration and contribute to tool life stability across batches.

Practical benefits on the shopfloor: handling, indexing and process security

A 0.8 mm corner radius offers a compromise between edge strength and fine contouring capability, while the 0° rake angle supports low cutting forces during finishing actions on steel. The insert’s with hole configuration simplifies replacement and torque control at mounting, decreasing downtime during index changes. For process planners, this means fewer adjustments, steadier feeds and the potential to tighten tolerances without compromising productivity. Advice on matching the NS9530 grade to holder geometry and machining parameters is available to ensure optimal results.

FAQ

What materials is this insert optimised for?
The SNGG120408-01 NS9530 insert is a finishing cermet grade optimised for steel turning operations, providing low cutting forces and improved surface quality.

Can this ISO insert be used in standard SNGG holders?
Yes, the ISO-standard geometry of the SNGG series ensures compatibility with standard SNGG holders when form, clearance and fastening match the insert dimensions.

How does the 0.8 mm corner radius affect finish and tool life?
A 0.8 mm corner radius balances edge strength and surface finish: it supports fine surface quality while offering sufficient robustness for finishing passes.

Is the NS9530 grade coated or uncoated?
The NS9530 grade is specified as an uncoated cermet, chosen for its sharp cutting edge and consistent finishing performance on steel.

What is the benefit of the cylindrical hole design?
The cylindrical hole facilitates secure clamping and repeatable seating, reducing setup variability and improving process stability during indexing.
