you sure can
It is a merchandising piece only (meant to illustrate the effectiveness of the magnetic screw holder) and can be discarded after purchase.
I was told it would fit any Dewalt drill
Yes it works with all standard drills.

It is a magnet that holds the screw head tight to the bit. I like them for drywall screws to create a little dimple to be filled with drywall mud. But it tends to get in the way for other applications like when the screw needs to be countersunk or in tight spots. The included bit holder can be used with or without the magnetic attachment.
It’s for doing drywall. Sets the screw at the perfect depth for mudding
yes for 1/8 is standard
I didn't notice until I read your question, but mine came with a plastic sleeve instead of a metal one too.
