CNGG120408 NS9530 indexable insert for Turning — Tungaloy (80° rhombic, 0.8 mm radius)

CNGG120408 NS9530 is an ISO-format rhombic turning insert designed for external and internal finishing cuts where low cutting forces and high surface quality are required.

*ISO-format rhombic insert, 80° angle *Uncoated cermet NS9530 for fine finishing *Double-sided geometry, cylindrical hole *Compatible with standard ISO toolholders

Delivering consistent fine finishing with lower cutting forces

The uncoated cermet NS9530 grade is formulated for finishing operations on steel, providing a sharp cutting edge and reduced built-up edge tendency. This results in lower cutting forces and improved dimensional control during continuous cuts and small depths of cut, making the insert suitable for high-quality surface requirements. The combination of the grade and edge geometry is intended to produce a high surface finish with predictable tool life under stable machining conditions.

Secure mounting and broad holder compatibility for process reliability

The insert is manufactured to ISO dimensions, with compatibility to a toolholder determined by form, relief angle, tolerance class, fastening, size and thickness. The rhombic 80° shape and cylindrical hole ensure repeatable indexation and clamping stability when used with standard clamping sets and screws. This standardised system design enables straightforward integration into existing turning setups and helps to reduce changeover times while maintaining machining accuracy.

Geometry and dimensions optimised for finishing applications

Key dimensions — size 12, thickness 4.76 mm and corner radius 0.8 mm — are chosen to balance edge strength and the fine-profile capability required for finishing. The 0° relief angle and double-sided configuration increase economical use by providing two cutting edges per index. Material selection and chipbreaker form are matched to continuous turning tasks, and the insert is supplied in the ISO CNGG format to simplify tool selection and ensure predictable behaviour in serial production.

FAQ

What materials is this insert intended for?
The CNGG120408 NS9530 insert is specified for finishing on steel; the uncoated cermet NS9530 is optimised for continuous cuts and small depths of cut to achieve superior surface quality.

How does the insert mount to a toolholder?
Mounting is achieved via the cylindrical hole and standard ISO clamping arrangements; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness, ensuring a secure fit in compatible holders.

How many cutting edges are available per insert?
The geometry is double-sided, providing two usable cutting edges per indexation, which improves cost-efficiency for finishing applications.

What are the key dimensions to check when selecting a holder?
Important dimensions to match are the size 12, thickness 4.76 mm, corner radius 0.8 mm and the 80° included angle to ensure correct seating and clearance.

Is this insert suitable for roughing operations?
This grade and geometry are optimised for finishing; for heavy roughing a grade and geometry designed for higher robustness would be preferable over the NS9530 finishing sort.
