TNMG 160408 NS9530 TNMG – Turning indexable insert by Tungaloy for precision finishing on steel, triangular ISO insert with 0.8 mm corner radius

The TNMG160408 NS9530 is a triangular ISO turning insert designed for finishing operations on steel, offering a sharp cutting edge and a double-sided chipbreaker suited to continuous cuts and small depths of cut.

• ISO triangular insert TNMG form
• Uncoated cermet grade NS9530 for fine finishing
• 0.8 mm corner radius for refined surface finish
• Double-sided design with central cylindrical hole

Delivering fine surface quality with an uncoated cermet grade

The NS9530 designation denotes an uncoated cermet optimised for finishing applications on steel; this material offers a sharper, more wear-resistant edge than many conventional carbides, which translates into lower cutting forces and an improved part finish. In practice, the finer microstructure of the cermet grade supports continuous cutting and small depths of cut, making the insert particularly suitable where surface integrity and consistent dimensional results are critical. The combination of the grade and geometry reduces the need for secondary finishing, supporting more efficient production cycles.

Stable clamping and ISO compatibility for predictable routines

Compatibility with holders is governed by the insert’s form, clearance angle, tolerance class, fastening method, size and thickness. The triangular ISO form and central cylindrical hole ensure secure seating in standard external holders or boring bars when used with the appropriate shim and clamping set. The double-sided chipbreaker extends usable edges between indexing operations, enhancing uptime. For process planning, consider the system as a whole: insert, external holder or boring bar, shim/clamp set and replacement screws — each element affects stability and repeatability.

Geometry tuned for finishing and controlled cutting forces

A 0.8 mm corner radius and a 60° included angle give a balance between edge strength and the ability to produce fine surfaces; smaller radii reduce cutting forces and allow smaller feed rates without sacrificing finish quality. The 0° clearance angle specified for this insert design reduces interference on finishing passes, while the 16 mm inscribed circle and 4.76 mm thickness provide the mechanical support needed for steady turning. The relatively compact geometry aids in reducing vibration in slender setups, supporting tighter tolerances and consistent surface roughness values.

Economic benefits through process reliability and simple setup

Selecting an insert with the right chipbreaker, grade and geometry reduces scrap rates and rework. The NS9530 finishing grade is engineered to maintain a sharp cutting edge under continuous conditions, which lowers machining variability and supports predictable tool-change intervals. For production environments that prioritise throughput and surface quality, the use of a purpose-matched insert contributes directly to lower overall machining costs and fewer process interruptions. Technical staff will appreciate the straightforward selection logic: match the chipbreaker and grade to the workpiece material and the required stability of the setup.

FAQ

What machining tasks is this insert best suited for? The TNMG160408 NS9530 Tungaloy insert is intended for finishing operations on steel where a sharp cutting edge and low cutting forces are required.

Is the cutting material coated? No, the NS9530 grade is an uncoated cermet, selected for its fine edge and surface-finish capability in continuous finishing cuts.

How does the 0.8 mm corner radius affect performance? A 0.8 mm corner radius improves surface finish while maintaining sufficient edge strength for fine turning, reducing vibration in stable setups.

Can this insert be used in standard ISO holders? Yes; compatibility is determined by plate form, clearance angle, tolerance class, fastening method, size and thickness and the insert should be mounted in a matching ISO external holder or boring bar.

What is included in the system when ordering? The primary article is the ISO insert; a complete working system typically includes the matching external holder or boring bar, shim/clamp set and replacement screws, which should be selected to suit the insert form and application.
