TPGT16T304 GT9530 Tungaloy triangle ISO turning insert — coated cermet, 0.4 mm corner radius

The TPGT16T304 GT9530 Tungaloy indexable insert is an ISO-standard triangular turning insert designed for finishing to light universal turning applications in steel.

• GT9530 coated cermet for extended tool life
• Triangle ISO insert, 16 mm size, 60° geometry
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with single-sided countersink 40°–60°

Engineered for consistent finishing and longer tool life

The GT9530 grade is a coated cermet formulated for wear resistance and consistent surface quality during finishing operations on steel. With a cemented carbide substrate and protective coating, the grade reduces flank and crater wear under stable cutting conditions, which translates into fewer insert changes and improved productivity. The selection targets applications where a fine surface finish and dimensional repeatability are priorities, delivering a balance between tool life and machining quality that is particularly valuable in serial production.

Precision geometry that stabilises the cutting process

A triangular 60° cutting geometry combined with a 0.4 mm corner radius and an 11° relief angle provides a controllable cutting edge for external and internal turning. The 3.97 mm plate thickness adds rigidity, while the 16 mm inscribed circle ensures compatibility with common ISO external holders. The central cylindrical hole with a single-sided countersink (40°–60°) supports secure clamping and repeatable positioning, which helps to maintain constant cutting conditions and reduces vibration-related defects during operation.

ISO compatibility and practical application guidance

These inserts follow ISO specifications for shape, relief, tolerance class, fastening and size, so compatibility with a matching external holder or boring bar depends on those parameters. The single-sided chipbreaker is optimised for finishing to light turning; selecting the correct chipbreaker and grade according to workpiece material and machine stability is essential. In practice, the insert suits external finishing passes and light-turning duties where good surface finish and predictable wear behaviour are required, contributing to reduced rework and higher first-pass yields.

FAQ

What materials is this insert primarily intended for?
The TPGT16T304 GT9530 Tungaloy insert is optimised for machining steel, offering wear-resistant performance for finishing and light universal turning tasks.

How does the GT9530 grade affect tool life and surface finish?
GT9530 is a coated cermet grade designed to improve wear resistance and maintain a consistent cutting edge, resulting in longer tool life and improved surface quality with stable cutting conditions.

Which holder features must match to ensure compatibility with this insert?
Compatibility requires a holder with matching shape, relief angle, tolerance class, fastening method, size (16 mm) and thickness (3.97 mm) to ensure secure clamping and repeatable positioning.

Is this insert suitable for internal turning operations?
Yes, the triangular geometry and controlled corner radius make the insert suitable for certain internal turning tasks, provided the holder and machine setup offer adequate rigidity and access.
