Description
Overview:
The Mexco 1 1/4" Male to 1/2" Male Adaptor (A30ADA1) is a precision-machined steel connector used to join tools and accessories with different thread sizes. It presents a 1 1/4 inch (31.75 mm) male thread on one end and a 1/2 inch (12.7 mm) male thread on the other, allowing you to pair compatible diamond core drilling equipment and related accessories without changing your main setup. Built for site conditions, the adaptor provides a firm, accurate fit to help maintain alignment and transfer torque reliably. It is suitable for hand-held and rig-mounted diamond core drilling systems and for users who need to bridge between common thread formats on cores, arbors, and similar tooling. A straightforward screw-on design keeps installation quick and dependable.
