TPGT 130302 NS9530 Tungaloy turning insert — triangular ISO finishing geometry

The TPGT130302 NS9530 is a triangular ISO turning insert optimised for finishing steel in continuous-cut turning, offering a sharp edge and low cutting forces for superior surface quality.

• ISO TPGT130302 geometry for standard holders
• Uncoated NS9530 cermet for fine finishing
• Sharp cutting edge with 0.2 mm nose radius
• Cylindrical hole with single-side countersink

Consistent finishing performance with low cutting forces

The combination of an uncoated cermet grade and a finely honed cutting edge gives a measurable advantage when producing high-quality external or internal turned surfaces. With a nominal 0.2 mm nose radius and a 60° triangular form, the insert supports small depths of cut typical for finishing passes while maintaining low cutting forces. The result is a reliable reduction in vibration and micro-chatter, which translates directly into improved surface finish and fewer rejected parts. For operations that demand continuous cutting at stable conditions, the fine-grained cermet substrate minimises built-up edge and holds a sharper profile over longer runs.

Robust chip control and predictable tool life

A single-sided chipbreaker geometry in this grade is designed to evacuate chips cleanly under typical finishing feeds and speeds. The NS9530 chemistry is tuned for finishing on steel: it preserves a sharp cutting edge and reduces the incidence of edge flaking in stable setups. Predictable chip formation contributes to safer cycle times and easier process parameter tuning, which supports higher first-pass yield and lower downstream rework. Combining the insert with the appropriate clamping set and holder ensures consistent seat contact and repeatable results across tool changes.

Practical compatibility and system considerations

Compatibility with a given toolholder is determined by form, clearance angle, tolerance class, fixation, size and thickness; the insert features a cylindrical hole with a single-side countersink (40°–60°) to match common clamping systems. The 11° clearance angle and 3.18 mm plate thickness provide a stable seating and allow the use of both external holders and boring bars where the ISO TPGT form is supported. For assembly, the usual system comprises the ISO insert, a matching external holder or boring bar, a backing/locking kit and replacement clamp screws. Clarifying holder style and seating dimensions before ordering avoids surprises at installation.

Practical benefits for workshop productivity

Using a finishing-grade cermet insert reduces downstream processing and polishing time by delivering near‑final surface integrity directly from the lathe. The sharp edge geometry and the NS9530 grade promote lower cutting forces and a reduced tendency to form built-up edge during continuous cuts; this means fewer interruptions and more predictable tool-change intervals. Where tight tolerances and consistent surface quality are priorities, the combination of ISO standardisation and a dedicated finishing grade supports straightforward process transfer between machines and operators.

FAQ

What machining tasks is this insert optimised for? The TPGT130302 NS9530 insert is optimised for finishing operations in turning, particularly continuous cuts on steel where a sharp edge and low cutting forces are required.

Can the insert be used in internal as well as external turning? Yes, the triangular ISO form and the 13 mm inscribed size make the insert suitable for both external and internal turning when paired with an appropriate holder or boring bar.

What does the NS9530 grade mean for surface finish? NS9530 is an uncoated cermet finishing grade that preserves a sharp cutting edge and reduces built-up edge, resulting in improved surface integrity and fewer polishing steps after turning.

How does the cylindrical hole and countersink affect clamping? The cylindrical hole with a single-side countersink (40°–60°) matches common clamping arrangements and ensures secure seating and repeatable clamping forces when used with compatible holders.

Is the TPGT130302 compatible with standard ISO holders? The insert follows ISO geometry for TPGT-form turning inserts; compatibility is determined by holder form, clearance angle, tolerance class, fixation, size and thickness, so verify these dimensions before selecting a holder.
