TPMT16T304 GT9530 Turning Insert — ISO triangular insert, coated cermet (Tungaloy)

A TPMT16T304-PS GT9530 ISO triangular turning insert engineered for finishing and light universal turning of steel where improved surface quality and extended tool life are required

• ISO triangular insert, 16 mm size
• Coated cermet grade GT9530
• PS chipbreaker for fine finishing
• 0.4 mm corner radius for smooth surfaces

Superior finishing courtesy of a coated cermet grade

The insert’s coated cermet substrate, designated GT9530, combines ceramic hardness with metal toughness to deliver improved wear resistance and consistent surface finish on steel. Cermet grades offer a fine-grain cutting edge that reduces built-up edge formation, making them especially suited to interrupted cuts or operations with stable machine and workpiece set-up. The result is fewer regrinds and predictable part quality over longer tool life.

Consistent geometry and chip control for predictable results

The ISO triangular form and the PS chipbreaker provide controlled chip formation and stable cutting forces, which support repeatable finishing passes. With an included angle of 60° and a relief or clearance angle of 11°, the geometry is compatible with standard ISO holders when the form, clearance, tolerance class, clamping and thickness match. Specifying the correct holder and ensuring rigid clamping are decisive for achieving the grade’s potential and avoiding vibration-induced wear.

Easy set-up and clear mounting features for production use

Mounting is straightforward: the insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for secure fastening in compatible holders. The thickness of 3.97 mm and the corner radius of 0.4 mm influence feed selection and surface finish — a smaller radius favours finer finishes at moderate feeds, while the plate thickness supports stable clamping under light to medium cutting forces. Include a suitable shim or clamping kit and spare screws in the system build for uninterrupted production.

FAQ

What materials is this insert suited for?
The TPMT16T304-PS GT9530 is formulated as a wear-resistant cermet grade optimised for machining steel in finishing to light universal turning applications.

How does the PS chipbreaker affect the cut?
The PS chipbreaker on this ISO triangular insert promotes fine chip control and a smoother cutting action, which helps to achieve a better surface finish and consistent chip evacuation during finishing passes.

Which holder characteristics must be checked before mounting?
Ensure holder compatibility by matching the insert form, clearance or relief angle (11°), tolerance class, clamping method, size and thickness (3.97 mm). The insert’s cylindrical hole with a 40°–60° countersink must also match the holder’s screw/counterbore arrangement.

Can the insert be used for internal turning?
Yes, the insert is suitable for both external and internal turning operations when mounted in an appropriate boring bar or internal holder that provides adequate rigidity.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius supports fine surface finishes at moderate feeds; it reduces the risk of edge chipping while maintaining a good balance between strength and finish quality.
