The problem is we have a 1/4" shank on a router bit that has over a 1" diameter cutting edge leaving limited suport at the base of the bit. With the 1/2" collet on the router and the 1/4" sleeve we still have not supported the bit properly. I would say no to using the 1/4" shank rail and stile bit.
Porter Cable have produced a new router bit called Posi-stop that shows how to support the 1/4" shank bits with large diameters.
Hope this was helpful, |
