TPGT 080204 GT9530 Tungaloy turning insert — coated cermet, 11° clearance

The TPGT080204L-W08 GT9530 is an ISO triangular turning insert for turning operations, optimised for finishing and light general turning of steel with a wear-resistant cermet coating.

• TPGT ISO triangular insert 080204
• Coated cermet grade GT9530 for steel
• 11° clearance and 0.4 mm corner radius
• ISO compatible with cylindrical hole and countersink

Improved surface quality and longer tool life for finishing operations

The coated cermet composition of this insert promotes a superior surface finish while maintaining wear resistance during steady cutting. The GT9530 grade combines a ceramic-rich cutting edge with a metal binder to resist flank wear and generate a fine machined surface on steel components. For precision-oriented production, this means fewer passes and reduced finishing stages while preserving dimensional stability and repeatability.

Predictable mounting and compatibility with ISO toolholders

As an ISO-standard triangular insert, compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert features an included angle of 60°, a 0.4 mm corner radius, an 11° clearance, and a plate thickness of 2.38 mm, together ensuring consistent seating in suitable indexable toolholders. The centre cylindrical hole with one-sided countersink (40°–60°) allows secure clamping and straightforward replacement, supporting tight process control in turning centres.

Process stability and practical benefits in production

Selecting the W08 chipbreaker with this coated cermet grade supports stable chip formation during finishing cuts, reducing the risk of built-up edge and rework. The carbide substrate provides the necessary toughness for interrupted cuts, while the coating enhances resistance to adhesive wear. For shops focused on productivity and consistent quality, this insert delivers predictable tool life and surface characteristics under stable cutting conditions.

FAQ

Is this insert suitable for finishing steel components?
The GT9530-coated cermet insert is optimised for finishing and light universal turning of steel, providing improved surface finish and extended wear resistance under stable conditions.

Can the insert be used for internal turning as well as external turning?
Yes, the triangular geometry and secure clamping via the cylindrical hole and countersink make it suitable for both external and internal turning applications when the holder supports the ISO 080204 format.

What does the W08 chipbreaker mean in practice?
The W08 chipbreaker is designed for finishing to light cuts; combined with the GT9530 grade it encourages controlled chip formation and a consistent surface quality in stable machining conditions.

How important is the 11° clearance angle for performance?
The 11° clearance ensures adequate relief behind the cutting edge, reducing rubbing and promoting consistent cutting forces, which helps the coated cermet edge maintain its finish and tool life.

Which toolholders are compatible with this ISO insert?
Compatibility depends on the holder's form, free clearance, tolerance class, fastening method, size and thickness; holders specified for ISO triangular inserts in size 08 and the 080204 footprint are appropriate.
