One Way Screw Driver Bit
The Klein 32558 Heavy Duty Ratcheting Screwdriver/Nut Driver with Cushion Grip includes an interchangeable shaft that holds six 6 universal tips.
Drills and impact drivers are similar in that they re both rotating power tools and they have some overlap in usage, but they work differently and have different strengths.
Drills apply a constant torque and tend to have good control across a range of speeds and clutch settings. They re good for work that requires care or precision, like drilling a hole or driving a a smaller screw.
Impact drivers provide much higher torque but in rapid bursts–very much like a hammer provides bursts of linear force. This makes them good for heavy-duty jobs like driving long lag bolts you can even take the lug nuts off your car wheels with most impact drivers, but the banging action makes them a little bit difficult to control. They re also not good for driving into something very soft–between the hammer strikes there s no torque applied and the bit can actually rotate backwards. You can see this by holding the chuck with your hands while the driver is on; you ll feel the pulsing of the strikes but chuck won t actually rotate. Finally, some impact drivers don t have a clutch, which means you need to be very careful if you re driving something that could be over-tightened or broken by the high torque.
Besides the higher torque, impact drivers have another huge advantage in that you don t have to hold them tightly to provide the torque. The momentum of the rotating striker inside is what provides the rotation force, so even when you re driving something very tough it s quite easy to hold the tool. Drills on the other hand provide a constant torque and require the user to provide the reaction and prevent the tool from spinning.
If you have to pick a single all-purpose tool for general DIY use, a drill is much easier to control and is useful in a wider range of situations.

I started using a DeWalt compact impact driver a couple of years ago, and will never go back to a regular drill/driver again, with a few exceptions.
When would one use an impact driver versus a regular drill?
Machines. Machines are all around us. Here is some of their very interesting lore.
Another great review, Bjorn. Unfortunately, every time I think I m achieving a nice rig, then you come and introduce new objects of desire, like the Skreddy.
