Hello,

I would like to attempt a tube setting for the first time. All the guidance I read says that the setting burr needs to be as close as possible to the size of the stone. The stones I would like to set vary from 3.8mm to 4.2mm. I couldn't find anywhere setting burrs with such a range of sizes. Would it be OK to use a 4mm burr for all of the stones?

Thanks in advance for your help.
