TPGT 16T302 NS9530 Tungaloy insert – ISO turning insert for finishing steel

The TPGT16T302 NS9530 is an ISO triangular turning insert engineered for finishing operations on steel, offering a fine corner radius and an uncoated cermet cutting edge for superior surface results

• NS9530 cermet finishing grade
• 0.2 mm corner radius for fine finishes
• ISO triangular 16 format, 60° included angle
• Cylindrical hole with single-sided countersink

Superior finishing and reduced cutting forces

The combination of the NS9530 uncoated cermet grade with a sharp cutting edge delivers low cutting forces and a high surface finish, making this insert particularly effective for continuous finishing passes and small depths of cut. The resulting reduction in process load improves dimensional consistency and often reduces rework, so finishing cycles become more predictable and economical. The design targets applications where surface quality and minimal cutting disturbance are priorities.

Reliable fit into ISO turning systems

Compatibility is determined by the insert’s form, relief angle, tolerance class, fastening, size and thickness, so the ISO designation guarantees straightforward matching with standard holders and boring bars. The triangular geometry with a 60° included angle and the cylindrical hole plus single-sided countersink (40°–60°) ensure secure clamping and repeatable seating. The 11° relief angle supports positive rake conditions for finishing, helping to maintain edge integrity and reduce vibration during operation.

Material build-up for consistent tool life

The insert is built on a robust hardmetal substrate with an uncoated cermet cutting composition (NS9530) tailored for steel finishing. This material pairing promotes stable edge formation and predictable wear behaviour under continuous cutting conditions. The practical consequence is less frequent index changes and steadier process windows, which contributes to higher uptime and consistent part quality in series turning operations.

Practical machining guidance and system requirements

For external and internal turning operations select the matching holder or boring bar, plus the required shim or clamping set and replacement screws to complete the system. The 0.2 mm corner radius is ideal for fine-profile work and minimal surface scallop; the plate thickness 3.97 mm and size 16 give the mechanical stability needed for finishing tasks. The one-sided chipbreaker suits stable cutting scenarios; select the chipbreaker and grade according to component material and machine/tooling rigidity to achieve the best trade-off between finish and productivity.

FAQ

Is this insert suitable for finishing steel components?
Yes. The TPGT16T302 NS9530 is a finishing-grade, uncoated cermet insert from Tungaloy designed specifically for steel finishing, delivering low cutting forces and an excellent surface finish in continuous cuts.

Which holders are compatible with this ISO triangular insert?
Compatibility follows ISO standards: the triangular 16 format, 11° relief angle and 3.97 mm thickness require holders or boring bars sized for 16 mm triangular inserts with matching clamping provisions and the corresponding shim or clamp set.

How does the 0.2 mm corner radius affect the machining result?
A 0.2 mm corner radius produces a finer surface finish and reduced scallop height on profiles, but it offers less blunt-edge strength for interrupted or heavily rough cuts; it is therefore recommended for finishing passes and stable cutting conditions.

Can this insert be used for internal turning as well as external turning?
Yes. The insert is intended for both external and internal turning; ensure adequate rigidity of the boring bar and machine setup and select the appropriate chipbreaker and cutting parameters for internal applications.

Is the NS9530 insert coated?
No. The NS9530 grade is supplied as an uncoated cermet on a hardmetal substrate, optimised for finishing steel with a sharp cutting edge and predictable wear behaviour.
