SPGT090302 NS9530 SPGT — Turning insert for finishing by Tungaloy

The SPGT090302L-W15 NS9530 is an ISO-standard turning insert designed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and consistent surface quality.

• SPGT090302L-W15 for precision finishing
• NS9530 uncoated cermet grade
• 11° relief angle for stable cutting
• 0.2 mm corner radius for fine finishes

Precision finishing with cermet technology

The uncoated cermet grade NS9530 provides a consistently sharp cutting edge that reduces cutting forces and improves surface finish in finishing applications. Cermet combines ceramic hardness with a metallic binder to maintain edge integrity under continuous cutting; this results in lower friction, reduced burr formation and improved dimensional consistency. The main benefit is a higher-quality workpiece surface with fewer secondary operations, which supports efficient production workflows and predictable part quality.

Stable chip control for continuous finishing passes

Equipped with the W15 chipbreaker, the insert promotes short, controllable chips during continuous cuts and small depths of cut, which helps avoid entanglement and tool marks. Controlled chip formation reduces the risk of workpiece damage and tool interference, contributing directly to cycle-time stability and operator safety. The chipbreaker geometry is particularly suited to applications where uninterrupted cutting and repeatable surface integrity are priorities.

ISO compatibility and straightforward toolholder matching

The insert is ISO-standardised, so holder compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The standard designation ensures interchangeability within ISO turning systems and simplifies inventory management. The plate features a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping, and the square format delivers four usable cutting edges. These attributes make the insert easy to integrate into existing tooling setups and minimise set-up time.

Practical handling and selection guidance

Key dimensions such as the 0.2 mm corner radius, 11° relief angle and 3.18 mm plate thickness balance edge strength and fineness of finish. The square plate format (size 09) gives multiple indexable edges, improving economy per insert in precision turning tasks. For finishing steel with small depths of cut and continuous feeds, the grade NS9530 is optimised to deliver low cutting forces and high surface quality. The insert SPGT090302L-W15 is therefore a practical choice where surface finish and process stability are decisive.

FAQ

What materials is this insert suited for?
The SPGT090302L-W15 NS9530 insert is optimised for finishing steel, offering low cutting forces and superior surface quality in continuous cutting conditions.

Can this insert be used for both external and internal turning?
Yes, the insert is designed for both external and internal turning; selection of holder and geometry should follow the ISO specification to ensure correct mounting.

How does the W15 chipbreaker affect performance?
The W15 chipbreaker ensures short, controlled chips in finishing operations, which improves surface finish and reduces the likelihood of chip-related interruptions.

What should be checked for holder compatibility?
Holder compatibility depends on the insert form, relief angle, tolerance class, fastening type, size and plate thickness; the ISO designation aids correct matching.

How many usable edges does the square insert provide?
The square format normally provides four indexable cutting edges, improving economy per insert when rotating edges.
