I needed to enlarge a previously drilled hole. Since I couldn’t use my hole saw’s pilot bit to center the hole, and I didn't have my drill press with me, I had to come up with a solution. What worked for me was to connect two hole saws together. One was the size of the existing hole. This saw "guided" the other hole saw that was the size of the hole I needed to drill.

Use dowel and pot magnet to pick up screws, use the bag so you don't have to pull all the screws off the dowel

Pick up loose screws nails in seconds, minus the dust. Screw a pot magnet (at most home centers) on the end of a wood dowel to create your “picker-upper.”Place an inside-out sandwich bag over the magnet and start sweeping the area.
