CNMG 090408 NS9530 indexable turning insert – Tungaloy, uncoated cermet, finishing for steel

CNMG090408 NS9530 Tungaloy insert suited for finishing and continuous turning operations on steel, designed as an ISO rhombic insert for compatible external holders and boring bars

• ISO rhombic insert CNMG 09 format
• Sharp uncoated cermet grade NS9530
• Corner radius 0.8 mm for fine finishes
• Double-sided with cylindrical hole
• 4.76 mm plate thickness for stability

Precision finishing with reduced cutting forces

The NS9530 uncoated cermet grade is engineered for finish turning of steel, providing a consistently sharp cutting edge that reduces cutting forces and improves surface integrity. The rhombic geometry with an 80° included angle and a 0° relief angle supports continuous cuts and small depths of cut, making the insert particularly suitable where low vibration and tight dimensional tolerances are required. This translates into fewer reworks and a steadier process, which benefits throughput and lowers unit cost over production runs.

Stable clamping and indexable economy

A double-sided configuration with a cylindrical hole and a plate thickness of 4.76 mm gives reliable mounting and even load distribution in the seat, so tool life can be maximised while maintaining process security. The 0.8 mm corner radius is geared towards superior surface finish on precision components; when paired with an appropriate holder and clamping set, the insert enables repeatable, efficient machining cycles with predictable tool change intervals.

Simple material matching and application guidance

This finishing grade is optimised for steels and continuous cutting regimes; select an appropriate chipbreaker and match the sort to workpiece stability and machining strategy. The ISO designation reflects universal compatibility standards: the insert’s form, relief angle, tolerance class, fastening method, size and thickness determine holder fit. For operations on cast iron, aluminium or exotic alloys, choose a grade and geometry tailored to those materials rather than this finishing cermet.

Productive surface quality and reproducible results

By combining a sharp edge geometry with cermet’s intrinsic resistance to built-up edge, the insert supports high-quality surface finishes and dimensional consistency across batches. The design reduces the need for finishing passes in many cases, improving cycle times. Where exceptional surface integrity is essential, this insert can form part of a standardised tooling setup that delivers constant results and reduces process variability.

FAQ

What materials is this insert best suited for?
The CNMG090408 NS9530 Tungaloy insert is formulated as a finishing grade for steel, offering low cutting forces and a sharp edge for continuous turning operations.

Can the insert be used in standard ISO holders?
Yes, the insert’s ISO rhombic form and specified thickness allow compatibility with ISO-compliant external holders and boring bars that match the size, thickness and clamping method.

How does the 0.8 mm corner radius affect surface finish?
A 0.8 mm corner radius on this cermet grade helps achieve a fine surface finish and reduces the need for secondary finishing passes when machining steel with stable cutting conditions.

Is the insert coated or uncoated, and what does that mean for wear?
The NS9530 grade is an uncoated cermet, which provides a very sharp cutting edge and excellent surface quality for finishing; it is optimised for continuous cuts rather than interrupted operations where coatings may offer additional protection.

How many usable edges are available per insert?
As a double-sided, indexable insert, the CNMG090408 offers multiple indexed cutting edges; exact count depends on the insert geometry and indexing practice for the toolholder system.
