Precision fine adjustment control

Easily converts into circle guide for making arcs and circles up to 32" in diameter
Includes pivot plate, dust extraction hood, vacuum hose adapter & attachment hardware
very nice for the price/ fit's more than Bosch routers
This guide works with my Dewalt 625 router and would probably fit many other brands and models.The rods are 3/8 " in diameter and appear to be spaced a little less than 4 inch's apart( Probably 100mm). Easy to operate and adjust and the dust control shroud is a real plus, since routers seem to produce the most dust in my shop. This is also easily converted over to use as a circle cutting jig as well. I like how it's set up so you don't have to cut any pivot holes in your project when cutting circles. They provide a pivoting pin with a wide foot that you tape down.You could also maker bigger circles simply by purchasing longer rods . For the money this is a really good valued edge and circle guide.
Must have accessory for your Bosch router
I bought the Craftsman universal version of this edge/circle guide back when I had a craftsman router and hated it. The Bosch version is much easier to attach to a bosch router and much easier to adjust precisely. If you have a Bosch 1617 you need this jig.
