SNGG 090302 NS520 Wendeplatten - Tungaloy

Take advantage of the combination of a cermet NS520 grade for superior surface finish, a fine 0.2 mm nose radius for precise finishing, and ISO conformity for straightforward toolholder compatibility. Order or request technical advice via Metav Werkzeuge to ensure the insert matches the machining stability and chipbreaker required.

SNGG 090302 NS520 — ISO turning insert for finishing (Tungaloy)

SNGG090302-01 NS520 is an ISO-standard square turning insert designed for finish to light machining of steel components

• Cermet grade NS520 for superb surface finish
• 0.2 mm nose radius for fine finishing
• ISO square insert 09, 90° cutting geometry
• Cylindrical hole, 3.18 mm plate thickness

Consistent finishing and improved surface quality

The combination of the NS520 cermet grade and the fine 0.2 mm nose radius delivers measurable improvements in surface integrity and dimensional accuracy for finishing operations. Cermet materials excel in adhesion and maintain a stable cutting edge, which produces a uniform wear pattern and reduces the need for rework. For components where surface specification and repeatability matter, this insert supports shorter downstream processing and more predictable results.

Productivity through predictable wear and process stability

Designed as a finish-oriented solution, the insert provides repeatable performance across batch runs thanks to the wear-resistant cermet and the square 09 geometry at a 90° approach angle. The small nose radius balances contact area and edge strength to maintain good surface finish without compromising edge life. In practical terms, the result is less scrap and fewer tool changes during long production runs, improving throughput and machine availability.

ISO compatibility and practical selection guidance

The insert adheres to ISO norms, so compatibility is determined by form, clearance angle, tolerance class, fixation method, size and thickness. The cylindrical hole ensures secure clamping; a plate thickness of 3.18 mm supports stable seating in standard holders. Select the chipbreaker and the exact grade based on workpiece material, machining stability and desired surface finish—NS520 is optimised for steel finishing. For mixed or unstable setups, choose a chipbreaker that aids controlled chip formation and reduces vibration.

FAQ

Which materials is this insert suited for?
The SNGG090302-01 NS520 insert from Tungaloy is optimised for finishing and light machining of steel, offering improved surface quality and consistent wear.

Which operations are recommended for this insert?
This indexable insert is intended primarily for external and internal turning operations with an emphasis on finishing passes and dimensionally critical work.

How does the 0.2 mm nose radius affect performance?
A 0.2 mm nose radius balances a fine surface finish with sufficient edge strength; the SNGG090302-01 NS520 produces smooth surfaces while maintaining acceptable tool life for finishing cuts.

What should be considered when selecting a chipbreaker?
Choose a chipbreaker that matches the workpiece material, cutting parameters and machine stability—this ensures controlled chip formation and protects the cutting edge of the Tungaloy insert.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO sizing; compatibility depends on form, clearance angle, tolerance class, fixation and plate thickness—verify holder specifications against the ISO code 090302.
