I’ll
start with batteries. The two main most frequent different types of batteries – nickel cadmium and lithium ion. A real difference is longevity and value. Nickel cadmium batteries don’t last extended and harder to recharge. However, due to their chemical nature, there’re less expensive than lithium ion. Lithium ion batteries last longer and recharge faster, but you are higher in price. I’d always recommend buying lithium ion ones.After
taking good care of batteries, your future question must be based on drill power. Power is measured in volts. If you are simply a regular DIY’er, then 12v (volts) cordless drill needs to be plenty of for your tasks. Professional workers use 18v drills for those times you will takes place cordless drill often, you might as well spend a little more money and get one and that means you know your drill is good enough even for most demanding jobs. Before choosing new cordless drill, you need to know something about torque in addition. More torque equals more force if you drill something. That may be proportional for the material. If you intend to implement drill on hard surfaces (concrete, steel…) then you certainly should by all means obtain a drill with plenty of torque.From my experience,
when they are not choose a cordless drill with variable speed control. Which is really important feature and i believe every drill really should have it. Basically, it prevents sudden rush of power and torque for those who press the trigger too difficult. It can make you able to fine tune the level of torque you want. Like that you may use your drill on hard surfaces additionally, on soft surfaces which need additional care.
