TPGT 130304 GT9530 Turning insert by Tungaloy — ISO triangular insert for turning, coated cermet

TPGT130304 GT9530 is a compact ISO triangular turning insert designed for external and internal turning, optimised for finishing and light universal steel applications.

• Coated cermet GT9530 for extended life
• 60° triangular geometry for versatile turning
• 0.4 mm corner radius for fine surface finishes
• Compatible with ISO turning holders

Reliable finishes and longer tool life from GT9530

The coated cermet grade GT9530 is formulated for wear resistance and a stable cutting edge, making it suited to finishing and light universal turning in steel where surface quality and run time matter. The combination of a specific chipbreaker and a hard-wearing cermet coating produces consistent chip control and reduces flank wear, which in turn supports longer intervals between insert changes. In practice, this means fewer interruptions to production and a predictable part finish when machining under steady, well-supported conditions.

Secure seating and predictable clamping for consistent results

Compatibility with the toolholder is determined by geometry, clearance angle, tolerance class, attachment method, size and thickness. The insert’s triangular shape with a 60° included angle and a 0.4 mm corner radius provides predictable engagement with standard ISO holders. The central cylindrical hole with one-sided countersink (40°–60°) ensures secure clamping and repeatable seating, lowering the risk of movement under load and helping to maintain part tolerances across batches.

Practical selection and machining guidance

The substrate of cemented carbide and the GT9530 coating make this insert a choice for users aiming for improved surface finish and longer tool life in stable setups. For rougher or interrupted cutting, a more robust grade may be preferable; for finishing, the single-sided chipbreaker and 11° clearance angle support smooth shearing and low built-up edge. When selecting parameters, consider stable workholding and appropriate feeds to exploit the insert’s strengths: modest feedrates and correct depth of cut will enhance surface integrity and tool longevity.

FAQ

What applications suit this insert best?
The GT9530-coated triangular insert is intended for finishing and light universal turning of steel, delivering good surface quality and extended life under stable machining conditions.

How does the insert secure to the holder?
The insert features a cylindrical hole with a one-sided countersink (40°–60°) to ensure secure clamping; compatibility depends on holder form, clearance angle, tolerance class, attachment and size.

Which materials can be machined with this grade?
This insert’s coated cermet grade is optimised for steel machining where a fine surface finish and wear resistance are required.

What are the key dimensional values to check before fitting?
Verify the 0.4 mm corner radius, 11° clearance angle, plate thickness of 3.18 mm and the 13 mm plate size against the holder specifications for correct fit and repeatability.

Can the insert be used for internal turning?
Yes, the geometry and chip control make it suitable for both external and internal turning, provided appropriate holder selection and stable setup.
