Does any one out there have a Porter Cable 7539 plunge router? I need to know the maximum radius bit it will take. I called their wonderful technical support phone number and after a few minutes of playing pass the caller I was disconnected. If you could measure the inside diameter of the plunge base not the sub base it would be greatly apprechiated

If you are mounting it in a table (the only really safe way to use large bits) you could probably take the bottom plate off and make the hole in your mounting plate whatever size you need.

I will not be using the sub base but the plunge base of the router does not have that large of a diameter opening. I am really scared that a 3 1/2” diameter raised panel bit may not fit. I was hoping that someone on here would have one and could measure for me.

Have your say...
