TPMT 110208 AH120 — ISO turning insert, PVD-coated carbide, 60° triangular geometry (Tungaloy)

The TPMT110208-PS AH120 is an ISO-compliant triangular indexable insert designed for external and internal turning, offering a sharp cutting edge and process security for demanding lathe operations.

• PVD-coated carbide for wear resistance
• 11° clearance angle for stable cutting
• 60° triangular shape for versatile turning
• 0.8 mm nose radius for consistent finishes

Longer tool life through a wear-resistant grade

The TPMT110208-PS AH120 combines a PVD coating with a high-performance cemented carbide substrate to reduce flank wear and resist chipping during continuous turning cycles. This construction supports a more predictable tool life and fewer unplanned tool changes, which in turn improves machine uptime and reduces per-part tool costs. The result is a pragmatic balance between cutting-edge sharpness and enhanced process security, particularly where repeatability and productivity matter most.

Precision geometry for repeatable surface quality

The triangular geometry with a 60° cutting angle, paired with a 0.8 mm nose radius and an 11° clearance angle, has been developed to deliver stable cutting forces and consistent finishes on both external and internal turning passes. The combination of geometry and sharp edge condition helps to maintain dimensional accuracy and surface integrity, while the insert’s ISO format simplifies holder selection and replacement. The insert’s secure hole and countersink arrangement also contributes to a repeatable clamping position, minimising runout and vibration.

Versatile chip control and application matching

Equipped with the PS chipbreaker and the AH120 grade, this insert is suitable where a sharp edge and reliable chip formation are required. The chipbreaker style should be selected to match workpiece material, cutting mode and machine rigidity to achieve optimum performance. In practice, choosing the appropriate chip control and machining parameters enables efficient swarf evacuation and reduces the risk of built-up edge, improving both component quality and operator confidence.

Workshop integration and selection guidance

The insert forms part of an ISO insert system comprising the indexable plate, a compatible external holder or boring bar, a backing/wedge clamp and replacement screws. Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness, so checking these parameters against the holder is essential before purchase. For stock planning, using a standard ISO designation simplifies inventory and replacement. For further selection support, technical consultation is available to match holder geometry and cutting data to the machining task.
