SNGG 090308 NS520 ISO turning insert for turning (square, 0.8 mm radius) – Tungaloy

A SNGG090308-01 NS520 ISO-indexed turning insert designed for finishing and light turning of steel, featuring a 0° clearance angle and a cylindrical hole for reliable clamping.

• NS520 cermet for excellent finish
• Square insert with 90° approach angle
• 0° clearance angle for stable cuts
• Cylindrical hole for secure clamping

Consistent surface quality for finishing operations

The NS520 grade is a cermet developed for finishing to light machining of steel, prioritising surface integrity and dimensional stability. With a controlled edge geometry and a 0.8 mm corner radius, the insert sustains even wear and reduces the tendency to produce chatter marks during finishes. The combination of the cermet grade and the insert geometry supports predictable workpiece results, making it suitable for high-value components where surface quality and tolerance adherence are decisive.

Predictable clamping and ISO compatibility

Compatibility with ISO-indexed toolholders is determined by form, clearance angle, tolerance class, mounting and plate dimensions; this insert follows ISO standards for easy integration. The cylindrical hole and the square plate form provide consistent seating in standard pockets, reducing set-up variation and enabling reproducible clamping forces. For production environments that require repeatability between tool changes, the standardised form factor simplifies inventory management and reduces machine downtime.

Chip control and machining stability explained

The insert is supplied with chipbreaker 01, which is matched to finishing and light turning conditions to guide chip flow and avoid entanglement at low cutting depths. A modest 0° clearance angle contributes to predictable contact mechanics between insert and workpiece, offering stable cutting forces that benefit small-depth finishing passes. These features combine to lower the risk of built-up edge and to maintain a steady cutting process during extended runs.

Grade composition, geometry and recommended use

The SNGG series insert uses the NS520 sort, a cermet or coated cermet grade intended for fine finishing of steel, delivering uniform wear and good dimensional control. The square plate (size 09) with a 3.18 mm thickness supports light to medium clamping loads while the 90° approach geometry enables versatile turning set-ups. For best results select a matching holder and cutting parameters tuned to finish passes; the insert is particularly effective where surface quality and repeatable tolerances are the priority.

FAQ

What materials is this insert best suited for?
The SNGG090308-01 NS520 insert is optimised for finishing and light machining of steel, delivering high surface quality and uniform wear when used under appropriate cutting conditions.

Which toolholders are compatible with this insert?
Compatibility depends on the ISO pocket geometry; the SNGG090308-01 fits ISO-indexed turning holders that accept a square insert of size 09 with a cylindrical hole and the specified thickness.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius balances edge strength and finish: it increases resistance to edge chipping compared with finer radii while still permitting fine surface results during finish passes.

What is the purpose of the cylindrical hole?
The cylindrical hole provides consistent positioning and stable clamping in compatible toolholders, minimising rotational movement and ensuring repeatable seating during tool changes.

Is this insert coated or uncoated?
The product is supplied in the NS520 sort, which is specified as a cermet or coated cermet grade, tailored for fine finishing of steel.
