TPGT16T304 NS9530 Tungaloy turning insert — triangular insert for fine finishing with 11° clearance

TPGT16T304 NS9530 is an ISO‑standard triangular turning insert designed for precision finishing of steel; it is intended for continuous cuts and small depths of cut in turning applications.

• ISO triangular insert TPGT16T304
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge, low cutting forces
• 0.4 mm corner radius for superior finish
• Cylindrical hole with 40°–60° countersink

Consistent fine finishing and measurable productivity gains

The insert is engineered for finishing operations where surface quality and dimensional control are decisive. The uncoated cermet grade NS9530 delivers a sharp, wear‑resistant cutting edge that keeps cutting forces low, which in turn reduces vibration and tool‑holder deflection. For production environments this means fewer rework cycles and tighter tolerances under continuous cutting conditions. Performance metrics such as improved surface roughness and longer intervals between indexings are an immediate, verifiable benefit.

Geometry that simplifies set‑up and ensures repeatability

A deliberately chosen geometry — triangular shape, 11° clearance and an included angle of 60° — makes the insert suitable for a broad range of external and internal turning tasks while maintaining a compact mounted profile. The cylindrical hole with one‑sided countersink (40°–60°) ensures secure clamping and reproducible seating, so assembly tolerances are respected across tool changes. Because the insert conforms to ISO form and size standards, compatibility with common holders and boring bars is straightforward and predictable.

Material and edge technology explained for dependable results

The cutting material is uncoated cermet NS9530, selected for low cutting forces and superior surface finish when machining steels. Cermet grades combine ceramic hardness with metal toughness to sustain a sharp edge at the surface, which is advantageous for continuous cuts and small depth passes. Users benefit from reduced burr formation and a finish that often minimises or eliminates secondary dressing operations, thereby shortening overall process time while maintaining component quality.

Process integration: predictable performance and easier planning

Incorporating this insert into a turning cell supports stable process windows thanks to the combination of edge sharpness and modest corner radius. The 0.4 mm corner radius balances cutting strength with surface generation, offering reliability on long runs without sacrificing finish. The insert’s specifications permit straightforward calculation of cutting data and tool life expectations, making it easier to plan procurement, tool change intervals and to compare cost‑per‑part against alternative grades or geometries.
