• Coated cermet for fine finishing
• 60° cutting angle, 0.4 mm corner radius
• Cylindrical hole with single-sided countersink

Optimised performance for finishing and light universal turning

This indexable cutting insert delivers predictable performance in turning thanks to its coated cermet grade and rigid geometry. The Cermet coating balances wear resistance with a polished cutting edge, which improves surface finish while reducing the need for rework. For applications requiring consistent dimensional accuracy and a fine part appearance, the combination of a 60° cutting angle and a 0.4 mm corner radius supports stable chip formation and controlled cutting forces, resulting in reduced vibration and fewer surface defects.

Compatibility and secure clamping for predictable production

Mounted inserts depend on exact fit and tolerance; the ISO designation and form of this insert ensure compatibility with standard holders that match the insert shape, thickness and fastening method. The triangular form and the specified hole style — a cylindrical hole with a single‑sided countersink (70°–90°) — allow secure clamping in the appropriate external holder or boring bar, which increases process reliability and repeatability during batch production. Choosing the correct holder and tightening torque prevents slippage and preserves tool life.

Material suitability and operational benefits

The GT9530 grade was developed as a wear‑resistant coated cermet for finishing to light universal machining of steel, offering longer life under stable machining conditions. The insert’s carbide backing provides the necessary rigidity for interrupting cutting loads, while the cermet coating enhances thermal stability at the cutting edge. As a result, the insert lowers overall tooling costs by extending intervals between indexings and enabling improved first‑pass quality — a clear rational advantage in precision turning workflows.

Selecting the right insert and process tips

When specifying this ISO insert for turning, pick a single‑sided chipbreaker and match feed and speed to the recommended range for cermets: moderate cutting speeds with stable setup typically yield the best compromise between surface finish and tool life. For roughing‑to‑finishing transitions, the geometry and grade support a move to lighter cuts for superior part appearance without tool change. For further guidance on holder match and cutting data, consult technical datasheets or request application advice to secure optimal results.

FAQ

What materials is this insert suited for? This insert is designed for machining steel and is supplied in the GT9530 coated cermet grade to provide wear resistance and improved surface finish for finishing to light universal operations.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the insert’s ISO designation TPGH080204 helps to select a matching external holder or boring bar.

How does the 0.4 mm corner radius affect part quality? A 0.4 mm corner radius produces a stronger cutting edge and smoother workpiece surfaces at finishing feeds, while reducing the risk of edge chipping under stable conditions.

Is this insert suitable for interrupted cuts or unstable setups? The cemented carbide substrate offers rigidity, but the GT9530 cermet coating is optimised for stable conditions; for heavily interrupted cuts or unstable setups, evaluate alternative grades with higher toughness.
