VNMG 120402 NS9530 — Turning insert, rhombic ISO geometry (Tungaloy)

VNMG 120402 NS9530 is a precision finishing turning insert designed for steel turning applications, offering a sharp cutting edge and stable performance in continuous cuts.

• Uncoated cermet for fine finishing
• Low cutting forces for continuous cuts
• Rhombic ISO geometry, 35° lead angle
• 0.2 mm corner radius for precision

Achieve consistent, high-quality finishes on steel

The uncoated cermet grade NS9530 is engineered for finishing operations on steel. Its sharp cutting edge and material composition reduce built-up edge and minimise friction, which leads to improved surface quality and fewer passes to reach tolerance. For applications with small depths of cut and continuous cuts, this grade keeps forces low and chip formation steady. The insert VNMG120402E-PS is particularly suitable where a high-quality finish is the primary objective and where minimised cutting forces reduce spindle loads and tool vibration.

Predictable chip control and process stability

Equipped with a PS chipbreaker, the insert promotes consistent chip formation under finishing conditions. The combination of chip geometry and the 0.2 mm corner radius provides a controlled shear zone, which reduces the risk of irregular chips and improves machining stability. This predictability supports longer uninterrupted cycles and contributes to fewer part reworks. For production environments that favour repeatability and stable tool life, the construction and geometry of this insert provide a clear advantage.

Straightforward integration into ISO holders for efficient changeover

The insert follows ISO rhombic geometry and is compatible with standard clamping systems, where compatibility is determined by form, clearance, tolerance class, fastening and thickness. With a 12 mm inscribed circle and 4.76 mm thickness, the insert fits a wide range of VNMG-capable holders. The 0° relief angle and the 35° lead angle are optimised for turning applications that demand minimal radial engagement and precise contact. The cylindrical hole simplifies secure clamping via standard clamp sets and replacement screws, enabling quick tool changes and consistent seating in production tooling.

Application guidance and practical benefits

For finishing steel, select the NS9530 grade and the PS chipbreaker to exploit the insert’s low cutting forces and surface-finish advantages. The design supports continuous turning where vibration is low; in less stable set-ups, pairing the insert with a robust holder and optimised cutting parameters ensures best results. The insert’s geometry also eases programming choices on CNC lathes: a fine feed and modest depth of cut deliver the intended surface finish while preserving the sharp edge. If guidance on feeds, speeds or holder pairing is required, technical consultation is recommended to match machine capability, workpiece stability and desired outcomes.

FAQ

Which materials is this insert best suited for?
The VNMG120402E-PS NS9530 is optimised for finishing steel, offering a sharp edge and controlled cutting action suited to continuous turning where surface quality matters.

Does the insert fit standard ISO VNMG holders?
Yes. The rhombic ISO geometry and the 12 mm inscribed circle allow compatibility with standard VNMG holders, subject to matching the holder’s form, tolerance class and clamping style.

What is the role of the PS chipbreaker?
The PS chipbreaker promotes regular chip formation under finishing conditions, improving machining stability and reducing the likelihood of chip-related interruptions.

How does the 0.2 mm corner radius affect performance?
A 0.2 mm corner radius balances edge strength and fineness of finish: it supports high surface quality while maintaining adequate edge durability for finishing passes.
