The Osborne Manufacturing

This from Fine Woodworking: "There are a number of products on the market that offer quick changes between drill and driver bits, but none are quite like the Jack Rabbit ... Overall, this is a small but valuable drill/driver accessory. Precise manufacturing and clever engineering add up to efficient and accurate performance." How it works: The reversible screw tip goes in the chuck. A round magnet slides over the screw tip which more than doubles the power of the magnetic screw tip. The drill bit/counter sink snaps on over the screw tip. 1. Drill and countersink the hole. 2. Pop off the drill to expose the screw tip. 3. Drive the screw.
