The Beall Wood Threader Kit is an effective and easy to set up thread cutting system that facilitates the cutting of both male and female threads on dowels, nuts and custom parts.
Used in conjunction with your own router or a laminate cutter (not supplied) that clamps directly onto the unit, the kit includes everything you need to start cutting and tapping threads, including a 1/4 inch shank, solid carbide, triple flute router bit.
This set is for 1 1/2 inch threads and includes a specialist combination tap for cutting female threads, as well as the jig and carbide cutter for creating male threads.
Full instructions are supplied, but also see the excellent video below which is reproduced by kind permission of Ken at A Cut Above Woodworkings in Canada, which frankly shows everything you need to know about Beall Wood Threader Kits.
