|Blow moulded box|
I had about 400 pozidrive #2 head screws to put into a project I was building and didn't relish the task. Either I had to buy another drill or get a quick change head. I opted for the latter.
The device comprises:
- A main drive holder with a hex drive shank that fits into the drill chuck. It has a socket which takes the drill/driver holder
- A drill/driver holder
- 3 drills giving tapping size for #1 to #3 pozidrive/philips drive
- 3 countersink bits with clearance hole for the drills
- 5 drivers (3 #2 pozidrive, 2 #2 philips drive)
- 1 all key/wrench
- 1 blow molded box
In use you put the main drive holder into the drill and secure.

Next lock off the two grub screws securing the drill into the body of the drill/driver holder.
All that remains is to insert the driver into the other end of the magnetised holder and secure with a single grub screw.
Then it is a simple matter of inserting the drill/driver holder into the main drive body. It locks into place with a spring loaded latch.

You soon develop a skill of holding the electric drill and changing the bit with one hand.
