Enlarge holes by using an existing hole as a guide. Attach the original hole saw to this pilot and use it to center a larger hole saw. Pilot fits all brands of threaded hole saws.
Thread adapter is required for use on 1 1/8" diameter and larger hole saws to adapt 1/2"-20 threads to 5/8"-18 threads.
