I cut 25mm discs from 5/32” material and used them to fill 25mm bored surface hole to cover the embedded square nuts for bed bolts. As this work was on the inside of the bed rails, I did not bother to match grain, but the fit was still perfect, so with grain matching a near invisible repair would be possible. I also cut a 2” long dowel with the 15mm Plug cutter. In all cases the tools cut clean. Run drill press at low speed. This is a nice set that I am sure will come in handy for more special situations.
