	~~'''[[Screwdrivers#Powered_Screwdrivers\|Portable Electric Screwdriver]]'''~~

	Cordless power drills with speed and [https://en.wikipedia.org/wiki/Torque '''Torque Control'''] can be very effective also as powered screwdrivers but, more conveniently, a separate powered screwdriver can speed up working by avoiding the need constantly to change bits when drilling
	~~a series holes to receive screws. Such '''Drill Drivers''' are excellent when a constant [https://en.wikipedia.org/wiki/Torque '''Torque'''] for precision work is required.~~


	The effectiveness of '''[[Screwdrivers\|Powered Screwdrivers]]''' is enhanced if a hammer-type action is applied as the screw is turned. This is the case with an [https://en.wikipedia.org/wiki/Impact_driver '''Impact Screwdriver'''] but note that the ''hammer-action'' acts in the direction of rotation to increase torque and not along the axis of the chuck as is the case with a Hammer Drill. '''Impact Screwdrivers''' are popular with [https://en.wikipedia.org/wiki/Joiner '''Joiners'''] working on construction sites with long, modern wax-coated and self-countersinking screws which cut their own way through softwood building timbers avoiding the need for clearance or pilot holes. Instead of a keyless chuck, '''Impact Drivers''' have a collet which accepts drill bits with hexagonal shanks.
