Adapter F1-1/4″-7 Female to 5/8″-11 Male

Precision-machined thread adapter designed to run smaller diamond core bits on wet core drilling machines. This adapter converts a 1-1/4″-7 female spindle connection down to a 5/8″-11 male output, allowing compatibility with smaller core bits.

Most diamond core bits under 1-7/8″ diameter use a 5/8″-11 female thread, including the majority of dry-use diamond core bits. This adapter makes it possible to use those bits on equipment equipped with a 1-1/4″-7 female arbor.

Built for reliable alignment, secure engagement, and smooth operation in core drilling applications.
