WORX WX106 8V Cordless Rotary Tool - WORX UK 

I'm new to Dremels, but this thing has been great. ru-vid.comUgkxfPgcZ5_Cl0HDUKkMJAKde11YKQZVgMoR The variable speed is awesome and the cordless aspect makes it so easy to work with. I am constantly finding uses for it that make tasks easier. Recently I put in a new deadbolt on one of our doors. I knew I had to enlarge the hold where the deadbolt goes into the door frame. At first I thought I would have to get a big router and figure out how to use it for that, but then I rermembered we have the dremel. I was able to enlarge the hole almost as easy as if I was drawing with a pen. It's also great for grinding our dog's nails done and so many other household tasks.
