Cordless screwdrivers can be a great asset for crafters, do-it-yourselfers, woodworkers or handymen. A cordless screwdriver is a screwdriver that is powered by rechargeable batteries rather than an electrical cord. Unlike regular non-powered screwdrivers, a cordless screwdriver does not have to be manually twisted or turned. It also provides additional power far beyond what can be provided simply by the human hand.
Cordless screwdrivers have a powerful little motor that works both forward and in reverse. That means that not only can you screw in screws, but you can also remove them with ease. Most cordless screwdrivers can be used manually as well as with power, so if you want you can use them just like you would a standard screwdriver.
Cordless screwdrivers come with interchangeable bits so you can tackle a variety of jobs. The standard bits included with a cordless screwdriver usually include a flat bit, a Phillips head bit and various socket attachments. Because a cordless screwdriver has power, it creates more torque than standard screwdrivers. Torque is the term for a force that causes rotation, and having additional torque means that you can screw in screws more quickly and more easily than if you were doing them by hand.
The additional torque for a cordless screwdriver can also allow you to remove screws that are damaged or rusty. Often times these screws are impossible to remove with a standard screwdriver, but the additional power provided by the cordless screwdriver can help to remove them with ease.
Unlike drills, cordless screwdrivers are very compact and lightweight. Their smaller size allows you to fit them in tighter spaces than you could get into with a drill, thus making them more versatile for a wide variety of jobs or projects.
One great benefit of cordless screwdrivers is that because they don’t require the user to twist them they can help you to avoid repetitive motion injuries such as carpel tunnel syndrome or tendonitis. This is particular valuable for anyone who uses screwdrivers on a regular basis like crafters, woodworkers or anyone involved in the construction industry.
When buying a cordless screwdriver it is generally a good idea to buy a well known name brand rather than a generic screwdriver. The price difference is usually fairly minimal, but name brand screwdrivers usually have greater torque and are higher quality than generic screwdrivers. Additionally, cheap bits can easily break if put under too much stress so you may find that you are spending the money you saved by buying a generic screwdriver replacing its bits instead.
Look for a cordless screwdriver with a lithium-ion battery since these batteries provide longer running times and greater torque. To help the battery in your screwdriver last longer do not leave it plugged into the charger after it has been fully charged.
