As well as inserting screws, many cordless screwdrivers have additional features which are designed to make certain DIY tasks much easier. These include:
LED work light
For working in poorly-lit spaces.
Drill mode
Using your cordless screwdriver to drill holes.
Spindle lock
Enables you to lock the chuck so you can use the cordless screwdriver like a manual one and change between bits without having to worry about the chuck turning unexpectedly.
Hinged handle
Allows you to change the position of the cordless screwdriver and can be helpful when working in confined or hard to reach areas.
