TPGT130302 NS9530 — TPGT indexable turning insert, 60° triangular, uncoated cermet by Tungaloy

The TPGT130302 NS9530 is an ISO triangular turning insert designed for finishing steel, offering a sharp cutting edge and low cutting forces for continuous cuts and fine surface finish.

• Uncoated NS9530 cermet finishing grade
• 60° triangular ISO 130302 form
• 0.2 mm nose radius for fine finish
• Central hole with single-side countersink

Precise finishing for steel components with low cutting forces

The uncoated cermet grade delivers a sharp cutting edge and stable cutting behaviour that is optimised for finishing passes on steel. The combination of NS9530 grade and the fine 0.2 mm nose radius reduces ploughing and minimises built-up edge, which results in consistently improved surface finish and dimensional conformity. This makes the insert particularly suitable where small depths of cut and continuous turning are required; the geometry reduces cutting forces, which benefits thin-walled parts and setups with lower rigidity. The insert’s substrate and edge form ensure predictable wear progression, supporting cycle-time stability on production runs.

Secure clamping and ISO compatibility for repeatable results

The triangular 60° geometry and ISO designation ensure compatibility with standard holders when the form, relief angle, tolerance class, fixing method, size and thickness are matched. The insert features a cylindrical hole with one‑side countersink (40°–60°) for secure location and repeatable seating, plus a plate thickness of 3.18 mm that contributes to rigidity in the clamping system. With a 11° relief angle and standard ISO dimensions, the plate integrates into typical external holders or boring bars together with the required shim/clip and replacement screws, delivering consistent cutting orientation and repeatable part outcomes across batches.

Geometry and chip control tuned for continuous cutting and fine surfaces

A single‑side chipbreaker combined with the sharp edge profile supports controlled chip formation during finishing operations, reducing the risk of surface marks and facilitating stable tool life. The plate’s triangular shape (ISO 130302) and precise corner radius positioning enable multiple indexed corners for economic usage while maintaining edge quality. For shops seeking process reliability, the uncoated grade reduces the variability associated with coatings in fine finishing, allowing predictable tool behaviour and easier re-sharpening or replacement strategies. Selection of matching holder style and correct feed parameters will exploit the insert’s benefits in repetitive production environments.

FAQ

What materials is this insert suitable for?
The TPGT130302 NS9530 insert is formulated as a finishing grade for steel; the uncoated NS9530 cermet delivers low cutting forces and high surface quality in continuous turning of steel components.

How does the hole and countersink affect clamping?
The cylindrical hole with a single‑side countersink (40°–60°) ensures positive location and reliable clamping in compatible ISO holders, contributing to the repeatability expected from the TPGT130302 NS9530 insert (SKU TUN6997993).

Which operations benefit most from this grade and geometry?
Finishing operations with small depths of cut and continuous feed benefit most: the sharp edge and 0.2 mm nose radius reduce surface roughness and cutting forces, supporting precision external and internal turning tasks.

Can the insert be indexed for multiple corners?
Yes, the triangular geometry and ISO 130302 designation allow multiple corner indexing for extended usable life while maintaining the finishing edge quality provided by the NS9530 grade.
