CCMT120408 AH8005 CCMT turning insert — PVD-coated carbide, 0.8 mm radius (Tungaloy)

CCMT120408 AH8005 is a precision turning insert for external and internal turning of heat‑resistant alloys and hard materials, designed for ISO‑standard toolholders.

• PVD-coated cemented carbide
• Single-sided chipbreaker for stable cutting
• 0.8 mm corner radius for smooth transitions
• Cylindrical hole with 40°–60° countersink

Precision turning with reliable wear resistance

The insert combines a PVD-coated cemented carbide substrate with a wear‑resistant grade, offering predictable tool life when machining demanding materials. The PVD layer improves abrasive and adhesive wear behaviour, which translates into longer intervals between indexing and fewer unscheduled tool changes. For production environments that demand repeatable performance, this results in a measurable improvement in process efficiency and reduced downtime.

Geometry and chip control for stable machining

An 80° geometry and a single-sided chipbreaker deliver controlled chip formation and favourable cutting directions for both external and internal turning. The defined 7° clearance and the 0.8 mm corner radius promote consistent surface finish and reduce the risk of edge chipping under stable cutting conditions. These geometric attributes help maintain dimensional accuracy while ensuring chips are broken and evacuated reliably.

Compatibility and easy clamping in ISO systems

Designed as an ISO turning insert, compatibility with holders is determined by shape, clearance angle, tolerance class, clamping method, size and thickness. The rhomboid plate form and standard dimensions make it straightforward to find a suitable external holder or boring bar. The insert’s configuration — including the cylindrical hole with a one-sided 40°–60° countersink — supports secure clamping and straightforward replacement without additional adjustments.

Application focus: hard materials and heat‑resistant alloys

The AH8005 grade is formulated for the demands of heat‑resistant alloys and harder workpiece materials, where edge stability and thermal resistance are priorities. When combined with the right cutting parameters and a rigid setup, the insert contributes to higher material removal rates and a more reliable surface quality, making it suitable for small‑batch runs and serial production alike.
