OK, I'm in the process of making a set of adjustable height stands for the shop and I need to cut a 3/4" wide slot 1/4" deep. I have too many bits that could do that job but which is the best choice? I have several up spiral bits up to 1/2", I have a 3/4" straight cutter for a single pass, I have smaller straight cutters as well all being 1/2" shank. The 3/4" cutter is a two blade straight cutter whereas the 1/2" up cut spiral is 2 cutters but in a spiral which in my mind would make a cleaner cut. All would leave a flat bottom. The 3/4" bit is part of the MCLS 66 bit collection and what I would consider not as high a quality as my other Whiteside bits. The material being slotted is maple and this will be cut on the router table. The overall size of the boards is 1-1/2" x 2" x 28-/34" with a 3/4" centered slot cut 1/4" deep. What would you use, smaller cutter w/multiple passes, single pass 3/4" bit, or multiple passes with a spiral upcut bit?
