Query: STUPID CHUCK - DO NOT BUY!!!

SHAME on you Black & Decker.The chuck on this drill/driver make the unit totally worthless. It comes with a bit for driving or removing phillips and slotted screws, but the chuck opens when trying to remove a screw.The chuck does not tighten enough to hold a drill either. The drill bit slips easily.It has no torque adjustment.It does not have a low speed switch for driving screws.I have only used this unit about five times.It went to the landfill today, no recycle, no garage sale, just straight to the LANDFILL.Black & Decker has been added to my "NEVER BUY" list.STOP MAKING THIS UNIT Black and Decker!!!!
