I was looking for a router and router with upper and lower bearings to make simple patterns and to route and trim patterns. Having both an upper and lower bearing means a single bit can handle both jig and trimming tasks. The bit has a 1-1/2 cutting length, so it can handle fairly thick parts. With its 1/2" shank and about 2-1/2" overall length, it's probably best to use it on an under-table router rather than trying to use it in a hand-held router. 8" diameter may not be appropriate for veryโฆ
