This dowelling jig automatically centers itself on any board from 3/8″ to 2 3/8″ wide.
It comes with two sets of removable bushings for hole sizes 1/4″, 5/16″ and 3/8″, allowing you to drill two holes of the same size at one setting. An extra bushing set of these three sizes (one of each) is available separately.
Hole sizes 7/16″ and 1/2″ do not require bushings.
Made in USA.
