CCMT09T308 AH8015 ISO turning insert — PVD-coated carbide, 0.8 mm radius (Tungaloy)

The CCMT09T308 AH8015 is an ISO-format turning insert designed for both external and internal turning, optimised for heat-resistant alloys and general-purpose machining where a balance of wear resistance and edge stability is required.

• PVD-coated carbide grade AH8015
• ISO CCMT shape for standard holders
• 0.8 mm corner radius for robust edges
• Cylindrical hole with 40°–60° countersink

Durable performance for heat-resistant alloys

The insert combines a PVD-coated surface with a wear-resistant carbide substrate, making it a solid choice for machining temperature-stable alloys where sustained edge life is essential. The AH8015 grade is specified for a balanced combination of wear resistance and cutting-edge stability, which reduces frequency of index changes and supports consistent component finish. The one-sided chipbreaker aids predictable chip formation in typical turning operations, improving process reliability and reducing interruptions in production.

ISO compatibility and secure clamping for consistent accuracy

Supplied in the universal CCMT geometry, the insert aligns with ISO norms; compatibility with a holder depends on matching the insert form, 7° clearance, tolerance class, fastening style, size and thickness. The rhombic form with an 80° principal cutting-edge angle provides a favourable approach for many turning tasks, while the cylindrical hole with a unilateral countersink (40°–60°) ensures secure clamping and repeatable seating. With a plate thickness of 3.97 mm and an insert size of 09, mechanical fit and stability are straightforward to verify during tool selection and setup.

Practical guidance for turning applications

Intended for external and internal turning, the insert performs best when the chipbreaker and grade are chosen to match the workpiece material and the rigidity of the setup. The recommended system consists of the ISO insert together with a compatible external holder or boring bar, plus shim/clamp and replacement screws for safe assembly. The 0.8 mm corner radius offers a compromise between edge robustness and dimensional control, suitable for general finishing and light to medium roughing passes when stability is sufficient.

Productivity benefits and lifecycle considerations

By combining a PVD surface and a robust carbide substrate, the insert offers improved process security and predictable tool life, helping to lower overall machining costs through fewer tool changes and steadier surface quality. The balanced design supports stable chip formation and consistent cutting-edge behaviour, contributing to higher productivity in batch production or single-part runs where repeatability matters. Selection of the correct chipbreaker and machining parameters will further extend service intervals and reduce scrap risk.

FAQ

What materials can this insert machine effectively? The CCMT09T308 AH8015 insert is intended primarily for heat-resistant alloys; the AH8015 grade provides a balanced wear resistance and cutting-edge stability suitable for such materials.

Is the insert compatible with standard ISO holders? Yes—compatibility with a given holder requires matching the CCMT form, the 7° clearance angle, tolerance class, fastening type, insert size and thickness.

What does the chipbreaker specification mean for performance? A one-sided chipbreaker on the insert promotes predictable chip control in typical turning operations, improving process reliability and surface finish when matched to the workpiece and machining conditions.

How is the insert clamped in the toolholder? The insert features a cylindrical hole with a single-side countersink (40°–60°) to ensure secure seating and consistent clamping when used with the correct clamp or screw system.

Which system components are usually supplied with the insert? The system comprises the ISO insert itself, a matching external holder or boring bar, a shim or clamping set and replacement screws as required for assembly.
