Review on 📏 CMT 811-180-11 Straight 4" Inch Diameter by Jason Epstein

I was building a built in desk/bookcase and wanted to recess the shelves/table tops on the sides and back. The plywood I had was 18mm and it fitted well. This worked fine on a CNC router. After painting the parts I had to rub the edges with a bar of soap to fit them into the grooves I had made, but it worked.
