Good points ,thxIt depends. If you are going to use the T bolts that would work but if you are going to use 1/4 inch bolts it may not. I use a number of bolts in T-track and tracks I have routed out myself and they are thicker than the specific bolts shown in the picture.
Also, some of the bits will rout the vertical shaft as well as the track. Some, including mine, do not. That requires a 3/8 inch slot cut first, then run the t-track bit through that slot. Two steps but not a hassle.
I like this bit it has a heavy throat and cuts a larger slot.Rick,
I posted this thread showing a bit that will cut a slot that works perfectly with a common 1/4 20 bolt with a 7/16" hex head. It will also work with most 'toilet bolts'. Any bit that cuts a slot width over 1/2" will allow the hex head to turn, and less than 7/16" will not fit the cheaper 1/4 20 bolts. This bit was also pretty cheap at $13 through Amazon Prime. Good luck with whatever you choose.
