Cordless Screwdriver Review
Cordless screwdriver is an essential power tool for any home. It is a great power tool for working with wood, plastic, concrete, and metals. A cordless screwdriver is compact and convenient to use anywhere.
There are a lot of things to consider when buying power tools, particularly a good electric screwdriver.
Cordless screwdriver kit - accessories that come with your electric screwdriver. Determine what you will be using it for and what parts are included or absolutely necessary for your needs to avoid unnecessary shopping.
One note on screwdriver bits - when they finally break or get dull it is essential to replace them as fast and convenient as possible. This possibly requires switching to various sets from different brands so make sure your screwdriver can handle that.
Size and weight are essential to consider and depend on the amount and type of usage. However, what is more important to consider is the balance of the cordless screwdriver - how well it's chuck points straight ahead and doesn't tilt when you operate power tool.
Voltage and Intensity for the Current are important when choosing a cordless driver. The voltage for your future cordless power tool is directly related to the amount of usage. Choose low voltage power tool for rare usage and easy materials and higher voltage for professional, constant usage. The overall range is 3.6V(rare) to 12 - 14.4V(medium) to 24V(professional).
Adding to that, don't buy strictly by voltage. Not everyone needs maximum run time and power. Determine how much power and speed you need and what kinds of projects you'll be working on with your cordless screwdriver. In fact, some electric screwdrivers with lower voltage(14.4V) are faster and have more power than higher voltage(18V) models.
Battery consumption is another very important thing to consider. Battery life, same as voltage, depends on the type of job and the torque speed required to efficiently do the job. All but least expensive models come with two batteries and a charger so you can use one while charging another. Any battery system will do for simple short tasks. Select more substantial and reliable battery system and faster recharger(battery-charge indicator is a plus) for long jobs.
One thing to note - if you are choosing a cordless screwdriver with Li-Ion battery, be careful not to run it down to full discharge as it might die early, making an expensive mistake.
Grip of the cordless screwdriver can be made of reinforced plastic or rubber. While not completely protecting you from a possibility of an electrical shock, rubberized grip on cordless power tools is safer and more comfortable
Speed control gives options for having a slower speed for starting a hole easier with electrical screwdriver. Adjustable clutch for reducing torque is also available in some cordless tools.
Build-in LED light can be handy for dark places.
Brand. Well, this may be the most important thing to consider for an electric screwdriver. The quality of your power tool will certainly reflect in the quality of your work.
