CCMT 120408 AH725 Tungaloy indexable insert for turning — PVD-coated carbide, 0.8 mm corner radius

A bold, ISO‑standard CCMT120408 AH725 indexable turning insert designed for external and internal turning with a single-sided chipbreaker and PVD-coated carbide for stable cutting performance.

• ISO CCMT 120408 rhombic insert
• PVD-coated carbide grade AH725
• Single-sided chipbreaker for reliable chips
• 0.8 mm corner radius, 7° relief angle

Stable performance across mixed steels and stainless steels

The combination of the AH725 carbide grade and PVD coating delivers a balance between wear resistance and toughness, making this insert well suited to varying workpiece materials such as carbon and stainless steels. The universal, break-resistant grade is optimised for applications where material mix and process reliability matter; it reduces unplanned tool changes and supports steady cycle times. With the rhombic CCMT form and an included angle of 80°, the geometry contributes to predictable engagement forces and consistent surface finish, translating technical performance into measurable shop-floor productivity.

Secure seating and precise fit for consistent clamping

Designed to the ISO series, the insert’s dimensions and features ensure compatibility with standard external holders or boring bars when matching form, clearance, tolerance class, fastening and thickness. The plate thickness of 4.76 mm, the cylindrical hole with one-sided countersink (40°–60°) and the ISO designation guarantee repeatable mounting and torque distribution for stable turning. The single-sided chipbreaker and 0.8 mm corner radius provide controlled chip formation while the 7° relief angle helps to prevent rubbing on the flank face. These attributes simplify set-up and reduce the risk of seating errors that commonly affect process stability.

Robust grade and economical tool life for demanding production

The PVD-coated carbide construction provides good edge stability and extended tool life under interrupted cuts and shorter tool overhangs, which is particularly beneficial for smaller tools or operations with high demands on process security. The AH725 grade is engineered to resist chipping while maintaining cutting-edge integrity, offering an economical compromise between wear resistance and fracture toughness. In practice, this means fewer insert changes, lower tooling consumption and a steadier output—practical advantages for jobbing workshops and production environments seeking consistent component quality.
