Our new #7 Drill 'n Drive makes pre-drilling, countersinking and driving screws easy - all without having to re-chuck your drill - just drill, release, flip, lock and drive. The tool features a built-in hex key for replacing or changing driver and drill bits as well as adjusting pilot hole depth. A 1/8" replacement drill bit and our new T-15 and #1 square driver bits are included. Made in the U.S.A., with a limited lifetime warranty.
