I recently bought this McGill three hole paper drill - I have to say, it was the best $60 that I ever spent! This drill powers through up to 250 sheets of paper effortlessly. I recently had to make a stack of post bound albums, and this little beauty made them in half the time it would have normally taken using my old manual punch. I would recommend it to anyone who needs to punch holes in a lot of paper. It changed my life!
