I recently purchased the Sears "Professional" Lithium batteried driver
drills. I purchased two because I was in the process of erecting a metal
building. The batteries and charger worked good but the keyless chuck on
both drills exhibit what I call "Auto Loosen". I have several other keyless
chucks in my shop and none of these exhibit the same characteristics. I
called Sears Customer Service to complain and they told me to visit my local
Sears dealer. The local Sears dealer told me to call Customer Service.
Whoa!! I've been a victim of that before. I will now look for my tool
requirements somewhere else.

I've been replacing all those hand tighten chucks with the old keyed
type. I just can't get the hand tighten type tight enough, and the
chuck will slip, spinning around with the drill bit not moving. A new
chuck is pretty cheap, but getting the original one off can be a bitch
on some drills.
