Crank action screwdrivers pre-date cordless drivers, but they are still handy enough to be useful today. Trying to make their Rapi-Driv screwdrivers more functional, Klein now sells a version with interchangeable tips. They may not have been the first company to stick an interchangeable bit holder on their crank action screwdriver, but theirs is the only version I could find.
The Rapi-Driv screwdriver comes with a dual-ended bit. At one end is a 3/16″ slotted tip, at the other is a #2 Phillips, and in the middle of the shank is a spring loaded ball to lock it into the holder. It’s the same bit that’s used in their 10-in-1 and 11-in-1 drivers. So technically you should also be able to use any bit from either of those drivers.
If you want to carry one less screwdriver in your pocket, the new Rapi-Driv will cost you $10.
For extra credit, read what Harbor Freight says about their offset screwdrivers. Evidently the person that writes their copy doesn’t understand how these screwdrivers work, or basic geometry for that matter.
