Makes me think of my small Milwaukee driver. Has the QR chuck for the hex shank bits. I have a 3/8" chuck that fits when I want to use a standard drill bit, but it won't hold the smaller #50+ bits. For those I have a micro chuck with a 3/8"  shaft. Drill/chuck/cmaller chuck/bit. 

Kinda looks like a space weapon but all the nose heavy weight causes it to droop like a, well, that!
