Electric screwdrivers decrease the amount of work involved when driving multiple screws for a home improvement project. Most electric screwdrivers are cordless and use rechargeable batteries to power the tool. They use interchangeable bits so that you can choose the bit that's appropriate for the type of screw you need to loosen or tighten. Many manufacturers make cordless electric screwdrivers; changing the bit is similar for each brand of screwdriver.
Step 1
Push the directional switch on the screwdriver to the center, using your finger. The directional switch is usually located toward the front of the trigger.

Step 2
Remove the battery from the electric screwdriver to avoid accidentally turning on the tool while changing the bit. Some brands have two tabs on the side of the battery that you press in to pull the battery out; with other brands, the battery slides off the rear of the tool.
Step 3
Place your hand over the front of the screwdriver. Grab the collar -- the portion surrounding the bit -- with your thumb and fingers.
Step 4
Pull the collar toward the body of the screwdriver with your fingers. Hold it against the front of the screwdriver. This releases the bit. Pull the bit out of the screwdriver.
Step 5
Insert the appropriate bit for your project into the screwdriver. Push the bit into the chuck (the mechanism that holds the bit) until it seats in the back of the chuck.
Step 6
Release the collar to secure the bit to the screwdriver. Insert the battery.
Tip
Refer to your owner’s manual for specifics on your brand of screwdriver.
Warning
Use only the bits that come with your electric screwdriver. Screwdriver bits from different manufacturers are different lengths, and may not work properly when used with a different screwdriver brand.
