Wise Buys: Shelf-Pin Drilling Jigs
Why buy? A shelf-pin drilling jig ensures wobble-free adjustable shelves by helping you drill precisely positioned pin holes.
Shelf-Pin Drilling Jigs
We found two jig styles: a plastic or phenolic template with a single fence, and parallel aluminum guides. The template style comes with a self-centering 1/4"-diameter brad-point bit, but you also can get a 5mm bit for smaller pins or slightly larger bits for brass sleeves (shown at right). The parallel-rail type are built for heavy use and cost four to five times as much. (You supply your own drill bits for these.) We tested five template jigs and two rail jigs, and recommend the three on the following pages.
