TNMG220404 NS9530 – Tungaloy ISO turning indexable insert, uncoated cermet finishing grade

TNMG220404 NS9530 is an ISO‑standard triangular indexable insert engineered for turning operations, particularly finishing steel with low cutting forces and excellent surface quality.

• Uncoated cermet finishing grade NS9530
• Sharp cutting edge for high surface quality
• 60° triangular ISO form, 0.4 mm radius
• Double-sided chipbreaker with central hole

Precision finishing for demanding steel turning

The uncoated cermet NS9530 is formulated for finishing applications where surface quality and low cutting forces are decisive. With a sharp cutting edge and a small 0.4 mm nose radius, this insert favours continuous cuts and small depths of cut, reducing built‑up edge and leaving an improved finish on turned components. The carbide substrate provides dimensional stability under typical finishing feeds, making the insert suitable for repeated production runs where part tolerances and surface integrity matter.

Reliable fit and simple integration into existing tool systems

As an ISO turning indexable insert, compatibility is determined by geometry, clearance angle, tolerance class, clamping method, size and thickness. The TNMG form and 60° triangle ensure straightforward replacement in standard triangular holders or compatible boring bars; thickness 4.76 mm and inscribed circle 22 mm match common holder specifications. The insert is supplied with a cylindrical central hole and a double‑sided chipbreaker, enabling indexing to fresh cutting edges and stable clamping. Where tool systems require a shim or clamping set and replacement screws, the insert becomes part of a predictable system assembly that supports repeatable production.

Productivity and machining advantages for short‑cycle finishing

Choosing an uncoated cermet finishing grade like NS9530 helps to lower cutting forces and reduce vibration during fine turning, which benefits both tool life and machine load. The small corner radius and keen edge geometry support superior surface results without aggressive feeds, while the double‑sided chipbreaker assists chip control in continuous turning. For manufacturers processing steel where minimal material removal per pass is required, this indexable insert offers a cost‑efficient route to consistent finishes and reduced secondary operations.

FAQ

What is the primary application for this insert? The TNMG220404 NS9530 insert is designed for turning operations, specifically finishing steel where low cutting forces and superior surface finish are required.

Can the insert be indexed to a fresh edge? Yes, the double‑sided design and central cylindrical hole permit indexing to additional cutting edges for extended usage cycles.

Which holders are compatible with this ISO form? Standard triangular ISO holders and boring bars that accept TNMG‑form inserts with an inscribed circle of 22 mm and a thickness of 4.76 mm are compatible.

Is the NS9530 grade coated or uncoated, and what does that mean for finishing? NS9530 is an uncoated cermet finishing grade; this provides a sharp cutting edge and low cutting forces, optimised for fine surface quality in continuous turning operations.

How does the 0.4 mm radius affect the machining result? A 0.4 mm nose radius balances edge strength and surface finish, improving dimensional control and enabling smooth part surfaces with modest feed rates.
