Automatic Screwdrivers.
 

I bought a box of 25 DeWalt Pz 2 driver bits the other day for =A38.
That's 32 pence each. Also for sale were a selection of long shaft bits
which may have been useful for those converted drills that are used as
screw guns.

They were =A34.50 each.

Someone somewhere is getting ripped off.

Where can I get an adapter that will allow me to use my battery drills
as a belt feeder for those black screws that come in plastic strips?

Or a screw gun that uses small cheap bits?
