I bought a Whiteside 1/4" diameter spiral flush trim upcut bit RFT2100 to do some template routing at the router table. I also need to do some template routing with a 1/4" offset; this could be done by replacing the 1/4" diameter pilot bearing with a 3/4" diameter pilot bearing. I mistakenly thought that I could replace the 1/4" pilot bearing on the RFT2100 with a 3/4" pilot bearing. Unfortunately, the pilot bearing on the RFT2100 is not removable. Any suggestions on an alternative to the Whiteside RFT2100 that has a removable pilot bearing? I have made a test cut with a guide bushing/bit diameter that gives an offset of 1/4" but on the router table this means the template is hidden from view. I could also do it with a hand held router but prefer to stick to the router table. Any thoughts would be appreciated.
