Drill Warehouse 2 Pack 1/4 inch Hex Shank Drill Bits Screwdriver Bit Holder Screw Magnetic Drill Pack of 2

Absolutely the best magnet on a driver. I order 3 different drivers and this one by far had the best magnet. 3-4 times better than any of the other ones. Don't need to worry about the tip falling out. The magnet will definatly hold it in place.

Nothing special. Not sure what the outside collar and o-ring are for. I don't see a "spring loaded ball bearing on head". Also, what is the "Exclusive hex shank locking system."?

very cheaply made. They both ripped apart within a few weeks. Cheap metal. Don't waste you money.

Not quick change, just magnetic.

Exerllent

they work good but you half to keep gusting them.

Very handy to have around, Holds the longer bits nicely, the magnet is strong. It doesn't hold the small screwdriver bits as it is too deep but is perfect for the longer ones. Came in nice case too. THe blue makes it easy to spot in my tool bag also.
