This will be not news to the woodworkers and cabinet makers out there. You can use Forstner Bits when you want to drill a really clean hole in wood. The pic on the left below shows the BACK side of plywood that I drilled holes through. At least with me when drilling plywood I often end up with breakout on the back side; splinters of wood sticking out. Not so using these bits. The bit in the left pic is 1/4″. The other pic has a much larger bit for the purposes of illustration. The bits are available at Menard’s and Home Depot.
