TPGT16T304 NS9530 Tungaloy indexable insert for Turning (triangular, 16)

TPGT16T304 NS9530 is an ISO-standard indexable insert designed for finishing turns on steel, offering a sharp cutting edge and one-sided chip control in a triangular 16-size format

• Sharp cutting edge for fine finishing
• Uncoated cermet grade NS9530
• 11° clearance for stable cutting action
• Triangular 16 format with 0.4 mm corner radius

Consistent fine finishing for steel components

The uncoated cermet NS9530 is engineered as a finishing grade for steel, delivering a combination of a sharp cutting edge and low cutting forces that reduces the tendency for material smearing and improves surface integrity. For operations with small depths of cut or continuous cuts, this chemistry and edge geometry produce a superior surface finish and dimensional consistency, making the insert especially suitable for precision external or internal turning where visual and tactile quality matter.

Stable geometry and reduced vibration for repeatable results

The triangular form with a 0.4 mm corner radius and an 11° clearance angle supports stable chip formation and predictable load distribution at the cutting edge. The compact geometry helps to minimise chatter in less rigid setups and to maintain repeatable part tolerances across batches. Selecting the matching external holder or boring bar with the correct tolerance class and fastening method is essential to exploit the insert’s geometry for reliable, repeatable machining.

Practical chip control and mounting features for production use

The insert is supplied with a one-sided chipbreaker and a central hole with a cylindrical hole plus single-sided countersink (40°–60°) to ensure secure clamping and consistent chip flow during finishing cuts. The standard ISO design enables integration into common tool systems; the overall system includes the ISO insert, a suitable external holder or boring bar, shims/locking sets and replacement screws to maintain uptime and straightforward replacement routines on the shop floor.

Application guidance and system considerations

Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness—check that the chosen clamping seat matches the insert’s dimensions (16-size, 3.97 mm thickness) and the intended cutting forces. The NS9530 finishing grade performs best in continuous cutting on steels and small depths of cut; pairing the insert with a rigid setup and appropriate cutting parameters yields the best balance between surface quality and tool life.

FAQ

What materials is this insert suitable for?
The TPGT16T304 NS9530 is optimised as a finishing grade for steel and achieves best results on continuous cuts and small depths of cut.

Does the insert require a special holder?
A standard ISO-compatible external holder or boring bar is required; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness.

What is the advantage of the NS9530 grade?
NS9530 is an uncoated cermet grade that provides a sharp cutting edge, low cutting forces and improved surface finish in finishing applications.

How does the 0.4 mm corner radius affect performance?
The 0.4 mm corner radius balances edge strength with the ability to produce a fine surface finish; it reduces stress concentration compared with smaller radii while preserving detail.

Is the insert supplied with mounting hardware?
The typical system comprises the ISO insert plus a matching holder, shim/locking set and replacement screws; check the parts list for specific delivery contents.
