I have been using this trusty pin vise for several decades to drill tiny holes by hand in tight spots where my cordless drill won’t fit into. I use it quite a bit to drill pilot holes for eye screws when installing hanging wire on my art pieces. I have a few bits that are the width of straight pins and smaller.
Here I am drilling holes in a base to which a small chair will be attached. I added a piece of green Frog Tape to the bit to serve as a depth gauge so the holes will be the same depth. Crude but effective and simple.
