Cordless drills are portable tools, which are the one-tool solution to drilling tasks. These drills use rechargeable lithium-ion batteries that are ideal when doing off-site work without electricity. A cordless drill has enough muscle to power through any drilling job.
One of the most common handyman tools, cordless drills feature portability in comparison with wired electric drills. One crucial step in selecting a drill is comparison between models and types of drills. Important factors are power, ease of use, and functionality. It is also important to know the specific function that is required for the tool to be purchased.
In most cases, the biggest and most powerful tool is the way to go, but this is not the case for portable power tools. Smaller types can perform just as well as the bigger ones. It is often the case that smaller drills may have more features than the larger drills, and for a lower price.
Cordless drills are a kind of power drill that uses rechargeable batteries. A common design is the hammer configuration, and most drills also have a clutch for driving screws. For tight, hard-to-reach places, a right-angle drill would be best, for example. However, what cordless drills trade for portability is sheer power - since it runs on a battery instead of power coming from an outlet, a cordless drill has less force and torque power than a corded drill. Though they are the best solution for most cases, a corded drill should be considered when power is a main requirement. Even though recent battery innovations allow significantly more power for drilling, the holes that a cordless drill makes have a larger diameter, which causes the battery to drain more quickly.
A spare battery is a large help for any worker. To use a cordless drill continuously, a worker needs one or more spare batteries. The benefit of a spare battery is that it can be charging while the drill is in use with the other battery, so that a worker can quickly change them if one dies. Otherwise, there can be a wait of over an hour while the battery charges. In an attempt to resolve this, quick-charge batteries have been introduced, and can charge in as little as 15-20 minutes, though it is still wise to have a back-up battery just in case.
