8. Pocket-Screw Jig
The Kreg Jig is popular with woodworkers who want to use pocket screws for their joinery, since it hides the fasteners. The tool is easy to use, even for first-timers. Besides its use for joining pieces of wood, it also works well for furniture repairs. A basic mini jig set that is used for drilling one hole at a time starts at $20, while four pocket-hole jigs cost about $100.
