When you look at the picture for this item, it shows four different shafts with small ends that could be put in a cordless drill and used. I got one shaft with a large end that cannot be used in a cordless drill. It also shows multiple cutting heads with the description saying from 30-160mm size cutters. I got one cutting head. The picture and description are both very misleading. I could understand a misunderstanding, but this is way over the top. I believe this is very dishonest.
