SPGT 090308 NS9530 (SPGT) — Tungaloy turning insert for finishing

SPGT 090308 NS9530 is an ISO-format, indexable turning insert designed for finishing operations on steel where surface quality and low cutting forces are required

• SPGT 090308 ISO turning insert NS9530
• Uncoated cermet for finishing steel
• 11° clearance angle and 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Achieve superior surface finish with low cutting forces

The uncoated cermet grade NS9530 is engineered for finishing cuts: its sharp cutting edge reduces cutting forces and supports continuous cuts and small depths of cut. The result is improved surface quality and dimensional control with reduced vibration tendency. The combination of an 0.8 mm corner radius and an 11° clearance angle helps maintain a stable cutting geometry, which is especially beneficial when tight tolerances and repeatable finishes are required in production runs.

Confident holder compatibility saves setup time

The insert follows ISO norms, so compatibility with the chosen toolholder is defined by form, clearance, tolerance class, fixing method, size and thickness. The insert is supplied in a square 09 format with a 3.18 mm plate thickness and a cylindrical hole with a 40°–60° one-sided countersink, simplifying clamping in many standard external holders and boring bars. A complete system comprises the indexable insert, a matching holder, a shim/clamping pack and replacement screws, which ensures predictable integration into existing tooling systems.

Efficient finishing across external and internal turning

This grade is intended for finishing of steel in both external and internal turning. With a single-sided chipbreaker selected to match workpiece stability, the insert maintains process security and consistent results across batches. Lower cutting forces translate into reduced spindle load and often longer tool life under continuous machining conditions, delivering both productivity and quality benefits in finishing operations.

FAQ

Which materials is this insert suited for?
The SPGT 090308 NS9530 insert from Tungaloy is a finishing grade primarily intended for steel; it performs best in continuous cuts and small depths of cut where surface quality is the priority.

How is the insert fixed in a holder?
The insert uses a central cylindrical hole with a one-sided countersink (40°–60°) for standard clamping; ensure the holder matches the insert form, size, thickness and tolerance class to secure correct positioning.

What does the NS9530 grade mean in practice?
NS9530 denotes an uncoated cermet composition with a sharp cutting edge optimised for low cutting forces and high surface finish during finishing operations on steel.

Can this insert be used for both external and internal turning?
Yes, the SPGT 090308 NS9530 is suitable for both external and internal turning; select a compatible chipbreaker and holder based on workpiece stability and machining parameters.
