One of them the most important things to keep in mind when looking for one of these drills is to first know what you intend to use it for. There are a few important factors to keep in mind what you are selecting a cordless drill.
Voltage
Voltage is very important and can be used to indicate how power a cordless drill is. The higher the voltage rating, the stronger the drill will be. Basically, it can bore into harder surfaces and deeper too. Keep in mind that higher voltage will mean higher costs and heavier weight. Consider carefully the type of tasks you plan to use the drill for. In general, you an use 12V and 18V power drills around the home for light to moderate tasks.
Backup Battery
There are quite a few drills that come with a wide assortment of different batteries. However, it’s good to always look for a drill with a second battery. That means you can work longer without having to charge the battery. When the power runs out, you simply switch batteries. Even if your drill does not come with a second battery, you will most definitely want to purchase one. It’s an investment well worth the money.
Speed (RPMs)
The speed of the drill is measured by RPM’s. Most simple drills with run at a fixed speed, though higher model drills will have variable speed settings that you can adjust. Soft materials will always need to be drilled into more carefully with less speed while harder surfaces will require faster speeds to penetrate. Look at getting a drill with variable speed – this makes them much more variable. Most Hitachi cordless power drill models are variable speed drills making them more useful.
Chuck Size
The chuck size will determine just how large a drill bit you can use it with. The most popular size is a 3/8 chuck which should allow you to tackle most household jobs. If you plan to get do some heavy drilling as a construction professional, you should look at getting a cordless drill with a larger chuck size.
