DCMT070208 AH120 indexable insert for turning (Tungaloy, PVD-coated carbide, 7° clearance)

A Tungaloy DCMT070208 AH120 indexable insert engineered for external and internal turning operations, providing a wear- and breakage-resistant grade for process-stable machining.

• PVD-coated carbide grade AH120
• 7° clearance angle for stable cutting
• 0.8 mm corner radius for defined profile
• Cylindrical hole with single-sided countersink

Stable edge life for continuous production

The PVD-coated AH120 grade combines a hard coating with a tough carbide substrate to deliver process security and resistance to chipping during turning. This results in a longer effective edge life under routine operating conditions, reducing unplanned tool changes and improving machine utilisation. The controlled coating ensures uniform wear, while the substrate preserves edge integrity where interruptions and intermittent cutting occur, supporting predictable production cycles.

Precise geometry for reliable chip control

The rhomboid plate geometry with a 0.8 mm radius and single-sided chipbreaker offers a defined cut profile that supports consistent chip formation and evacuation. The small corner radius enables accurate profile reproduction and reduces cutting forces in finishing passes, whereas the chipbreaker design assists in breaking and guiding chips away from the cutting zone. Together these features improve surface finish and lower the risk of built-up edge in medium to stable conditions.

Easy integration into ISO tool systems

Designed as an ISO-standard indexable insert, compatibility with appropriate holders is determined by form, clearance, tolerance class, fastening method, size and thickness. The 7° clearance and the plate thickness of 2.38 mm allow straightforward mounting in standard external holders or boring bars, while the cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable seating. This simplifies inventory planning and insertion into established tool systems.

Grade and application — when to choose this insert

This grade is specified for turning tasks where a sharp cutting edge and dependable performance are required. The combination of the AH120 coating and carbide base is suited to situations that demand wear resistance and fracture control rather than extreme thermal resistance. Use this insert for general external and internal turning where consistent dimensional results and reduced edge failure are priorities; selecting the correct chipbreaker and grade remains essential for the workpiece material and operating stability.
