A cordless drill is simply an electric drill that has switched the cord for a battery. The cordless drill became so popular because of its ease of use and convenience. If you are looking for the best cordless drill visit https://www.experteasy.com.au/blog/best-cordless-drills/.
All that hassle was eliminated once the cordless drill showed up. Like all technology, the rechargeable drill has been advanced through the years and most of this has to do with the battery. The first cordless drill used by most contractors came with the 7.2v nickel-cadmium battery pack.
The nickel-cadmium battery can take 12 hours to fully charge up and can have only about 90 minutes of work time. They are usually a bit heavy and unfortunately, their charge is lost relatively quickly.
Today, we have the best-selling 18V lithium-ion battery. It has a nice lightweight, recharges in a rapid 15 minutes, will provide four times the charge to work ratio, and can hold a complete charge for up to two years.
The lithium-ion does have a few drawbacks also; they do need to be replaced faster than the nickel-cadmium, they are a bit more costly and their function decreases in cold temperatures.
The current top-selling rechargeable drill is the Bosch PSB 18 LI-2 Lithium-Ion Cordless 1/2" Driver-Drill Kit. This Bosch drill is sturdy enough for the day-to-day use of the professionals and simple enough for the do-it-yourselfers.
