Ive worn out two battery operated screw drivers on my bikes and gun reloading duties. The ones I use are NOT the drill looking devices, rather the lower power single battery in the handle type. I use the 1/4" drive adapter to hook on the 1/4" sockets. These things are perfect for taking the body pieces, case bolts, around the house screws, etc. They really help in putting on a silencer or seat for instance where the bolt doesnt quite line up, you spin the bolt while jiggling the silencer and it threads right in. This is WAAYYY faster and easier than using a screw driver or ratchet. They have lower power so you dont strip or break the bolt or alum cases. Any one else using one of these things? Brand doesnt really matter as long as its one of the better quality units.
