I need to create a 2 1/2 circular recess in a hunk of wood for a project my son is working on. My largest forstner bit is 2 1/8. My instinct is to g et one of those adjustable hole bits and work in from 2 1/2 to 2 1/8 and le t the forstner gobble up the remainder. Depth is only 1/2 inch or so. I'm sure there is a better way to do this ... so let's hear from you guys :-)
