The self-aligning design ensures that both ends of the dovetail joint match up evenly every time, and new table router control knobs promise comfortable and accurate use. The 861 EZ Pro Dovetailer II Dovetail Jig is fully portable, includes a 1/2" dovetail router bit and features sturdy machined aluminum construction along with integrated clamps for precise attachment to the work piece. It is perfect for furniture building, cabinet making and other carpentry.
