SNMG 120408 NS9530 — ISO turning insert (finishing) by Tungaloy

A SNMG120408 NS9530 turning insert designed for finishing steel with a sharp cutting edge, low cutting forces and excellent surface quality.

• SNMG120408 ISO turning insert for finishing
• Uncoated cermet grade NS9530 for steel
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker, 0.8 mm corner radius

Reliable finishing performance for steel turning

The insert is an ISO‑standard square turning plate manufactured from cemented carbide and specified as an uncoated cermet grade NS9530. This combination is tailored to finishing operations on steel, delivering a sharp cutting edge and reduced cutting forces that translate directly into improved surface quality and stable machining at small depths of cut. As a finishing grade, the material is optimised for continuous cuts; the double-sided chipbreaker supports controlled chip formation, which lowers the risk of re-cutting and maintains consistent part appearance.

Precise geometry and secure clamping for repeatable results

Compatibility with toolholders follows the ISO system: fit is determined by insert form, relief angle, tolerance class, fastening method, size and thickness. Important dimensions are 12 mm insert size, 4.76 mm thickness, 0.8 mm corner radius and a 0° clearance angle with an included angle of 90°; the insert features a cylindrical centre hole for positive seating. These geometric details support stable clamping and repeatable indexing, reducing set‑up time and variation between cycles. Clear dimensional data simplifies holder selection and ensures the insert mounts correctly in a wide range of ISO-compatible carriers.

Productivity advantages and application guidance

In practice, the uncoated cermet NS9530 excels where a fine surface finish and low cutting force are priorities. The sharp edge reduces cutting energy and can help extend tool life when feeds and speeds are adjusted for finishing cuts. Manufacturers aiming for consistent part appearance in serial production will value the insert’s ability to produce smooth surfaces on continuous cuts. For users requiring adaptation to specific turning strategies or unusual steel grades, technical guidance is available to match cutting data and chipbreaker variants to machining stability and stock removal requirements.

FAQ

Which materials is this insert suitable for? The SNMG120408 NS9530 Tungaloy turning insert is specified as a finishing grade for steel, providing the sharp edge and chip control required for high-quality surface finishes.

Can the insert be used for continuous cuts and small depths of cut? Yes; the NS9530 grade is optimised for continuous cutting and small depths of cut, making the SNMG120408 suitable for finishing passes where stability and surface quality are critical.

What is the corner radius and how does it affect the finish? The insert features a 0.8 mm corner radius, which balances edge strength and the ability to produce a fine surface finish; a larger radius would increase edge robustness but can alter profile definition.

Is the insert coated? No; this SNMG120408 is an uncoated cermet grade (NS9530), selected to provide a sharp cutting edge and low cutting forces in finishing applications on steel.

What determines whether the insert fits a particular holder? Compatibility is governed by the ISO form, clearance angle, tolerance class, fastening method, insert size and thickness; ensure the holder matches these dimensions to guarantee correct seating and clamping of the SNMG120408 NS9530 insert.
