Seco 00039789 Anvil Pin Indexable Turning Seco-capto

Product Description

The SECO 00039789 is an anvil pin designed for indexable turning tools in the Seco-Capto toolholder system. This small but critical component seats beneath the cutting insert, providing a stable support surface that protects the pocket and maintains consistent insert positioning during turning operations. Compatible with 1/2 inch and 5/8 inch inscribed circle inserts, it is engineered to work within C4, C5, and C6 Seco-Capto toolholder styles. This part is installed by CNC machinists and toolroom technicians performing insert changes or toolholder maintenance.

This anvil pin is used in precision turning applications on CNC lathes and turning centers equipped with Seco-Capto modular tooling. It supports a broad range of CNGP and CNMA style inserts across multiple geometry suffixes. It is suited for both roughing and finishing turning operations where proper insert support is required to prevent pocket damage and ensure repeatable tool performance. Industry standard reference number RP6757 applies to this pin.

Installation Notes

Anvil pins are replaced by machinists or toolroom technicians during routine insert changes or when pocket wear is observed. Power down and lock out the machine spindle before accessing the toolholder. Use the appropriate torx or hex key as specified by the toolholder manufacturer when removing the insert clamp. Inspect the anvil seat and surrounding pocket for damage before installing the replacement pin.
