I recently had to create a circular hole in a brass plate that was 1.325"
diameter. Since this isn't an even inch or metric size, I used my 30+ year
old General adjustable circle cutter (which, according to the latest Enco
catalog I have is still sold in pretty much exactly the same form as the one
I have).

But I found this tool very difficult to adjust to an "exact" size and
wondered if there was anything out there that would be easier, perhaps
something with a screw-adjustment?

TIA
