Great precise make. You get 1/4'' or 6.35mm rod to center your router to the jig. So beware, if you don't have 1/4'' i.e. 6.35mm collet cone, you'll need to get one. Of course, you can try and center your router without this rod. I bought it for makita drt50 - it fits very nicely.
Better than I expected. Excellent !!!!
