CNGG 120404 NS9530 ISO turning insert for finishing — Tungaloy

The CNGG120404 NS9530 is an ISO rhombic turning insert engineered for finishing steel, offering a sharp cutting edge and optimised chip control in continuous light-depth passes.

• Uncoated cermet grade NS9530
• Sharp edge delivers fine surface finish
• 0.4 mm nose radius for precision turning
• ISO rhombic insert with 80° approach angle

Precise finishing with lower cutting forces

The combination of an uncoated cermet grade and a finely honed edge makes this insert particularly effective for finishing operations on steel. The NS9530 composition provides a balance between edge sharpness and wear resistance, resulting in low cutting forces and consistent surface quality during continuous cuts and small depth of cut conditions. For applications where surface integrity and dimensional tolerance matter, the fine nose radius and sharp cutting geometry reduce vibration and help achieve repeatable part quality.

Predictable compatibility for streamlined tool changes

Designed to the ISO turning insert standard, the indexable plate features a rhombic shape and an 80° geometry that align with common external holders and boring bars. Compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness, so using standardised holders ensures quick changeover and repeatable clamping performance. The standardised format supports lean toolroom practices by reducing setup time and simplifying inventory management for production environments.

Stable mounting and controlled chip formation

Mechanical stability is aided by a cylindrical hole for secure fastening and a plate thickness of 4.76 mm, which together provide reliable seating under cutting loads. The double-sided chipbreaker design offers two usable edges, extending the effective economy of the plate while maintaining consistent chip control and surface finish. The modest 0.4 mm nose radius suits fine finishing passes and delicate features, while the overall construction supports predictable tool life and safer machining cycles.

FAQ

What material is the insert best suited for? The CNGG120404 NS9530 insert is a finishing grade designed specifically for steel, providing a sharp edge and low cutting forces for continuous turning operations.

How many cutting edges does the plate offer? This indexable plate has a double-sided chipbreaker, giving two usable edges to extend tool economy before replacement.

What are the key dimensional specifications to check for holder compatibility? Check size (12 mm), thickness (4.76 mm), relief angle (0°), approach angle (80°) and the cylindrical hole; these determine proper fit in ISO-compatible holders.

Is the cutting material coated? The grade is an uncoated cermet (NS9530), optimised for finishing steel with a sharp cutting edge and good surface finish characteristics.

What finish quality can be expected with a 0.4 mm nose radius? A 0.4 mm nose radius supports precise finishing passes and helps achieve fine surface finishes while maintaining low cutting forces and reduced vibration.
