Great for smaller projects, thinner stock and repair applications. Drill pocket holes that are 25% smaller in diameter. Works with 1/2 in. stock and narrow stock, down to 1 in. wide. For use with ¾” and 1” screws (I'll throw in a bunch of each screw type). Note: Kreg says this jig is for use with the newer (more expensive) 7000-series jigs, but I’ve been using it with my K5 jig and my son uses his with the K4 jig.
