The long style drill bushings are the same as those used in our "Dowl-it" doweling jigs. The threaded portion is 1/2 x 20 fine thread and the 1-3/4" length provides a long guide for very accurate drilling. The knurled head makes it easy to install and remove. Made of special tempered stell with rust-resistant finish.
