TPGT 130302 NS9530 Tungaloy turning insert – triangular 13 mm, 60°

TPGT130302 NS9530 Tungaloy-Wendeplatte is an ISO-format triangular turning insert designed for finishing operations on steel, offering a sharp cutting edge and low cutting forces for continuous cuts and small depths of cut.

• ISO triangular insert TPGT 130302 format
• Uncoated cermet grade NS9530 for finishing
• 13 mm inscribed circle, 3.18 mm thickness
• Cylindrical hole with 40°–60° single-side countersink

Exceptional surface quality through a finishing-grade cermet

The TPGT130302 NS9530 is a purpose-built finishing insert made from an uncoated cermet grade optimised for steel. Cermet combines ceramic hardness with metallic toughness, which produces a sharp cutting edge that reduces built-up edge and lowers cutting forces. This characteristic directly benefits surface integrity: parts require less downstream polishing and meet tighter surface-roughness targets with fewer passes. For shops seeking consistent finishing performance, the material choice yields shorter cycle times on continuous-feed turning operations while preserving dimensional accuracy.

Secure clamping and geometry that reduces vibration

The triangular ISO geometry with a 60° included angle provides three usable corners per indexable insert and a compact seating footprint that contributes to rigidity in the toolholder. The insert’s dimensions — 13 mm inscribed circle and 3.18 mm thickness — combined with an 11° relief angle ensure compatibility with a broad range of ISO external and internal turning holders. Stable seating and correct tolerance matching reduce micro‑movement at the cutting edge, which in turn extends edge life and improves repeatability across multiple workpieces. Choosing the appropriate holder, underlay and clamp is essential to unlock these benefits.

Designed for continuous cuts and precise small-depth finishing

A single-sided chipbreaker and a 0.2 mm corner radius make the insert particularly well suited to continuous cutting and small depth-of-cut finishing operations where low cutting forces and fine surface finish are priorities. The through-hole design with a cylindrical hole and single-side countersink (40°–60°) provides reliable mechanical clamping and fast index changes. Use of this insert in finishing passes lowers vibration sensitivity and allows stable feeds at modest depths, giving a predictable trade-off between surface finish and tool life. The insert is intended for turning applications, both external and internal, where surface quality is decisive.

FAQ

Is this insert suitable for finishing steel components?
Yes. The NS9530 uncoated cermet grade is a finishing sort designed for steel, providing a sharp cutting edge, low cutting forces and improved surface finish for continuous cutting and small depths of cut.

What geometry features affect machining performance?
The triangular form with a 60° included angle, 0.2 mm corner radius and 11° relief angle combine to reduce cutting forces and vibration, supporting high-quality surface finishes in finishing passes.

Which toolholders are compatible with this insert?
Compatibility depends on the holder’s seat form, relief angle, tolerance class, attachment and size; choose an ISO-compatible external or internal turning holder that matches the insert’s 13 mm inscribed circle and 3.18 mm thickness.

Can the insert be used for internal turning operations?
Yes. The insert is suitable for both external and internal turning applications when mounted in an appropriate holder and clamping system.

How is the insert fixed in the holder?
The insert features a through hole and a cylindrical hole with a single-side countersink (40°–60°) to enable secure mechanical clamping and straightforward indexing; reference SKU TUN6997961 for exact fitment details.
