Kreg says its new 300-series pocket-hole jigs make project building faster and easier. The jigs boast a simplified setup process that requires only a few simple steps according to the company, and features an anti-slip base to hold the jig in position. The Jig 320 works with materials of any thickness between one-half and one and a half inches and features two drill guides, a removable spacer, a material thickness gauge/hex wrench, and an easy-set drill bit and stop collar. The Jig 310 shares the same design in a smaller package.
