There are all kinds of cordless drills, but they might not have enough power to do the job. 24V cordless drills are heavy duty and have more strength than the popular 18 volt cordless drills. They are capable of heavy duty jobs, like drilling through concrete or brick and they are capable of hammer drilling, rotary drilling and chipping because there will be different modes to accommodate different tasks.
There is a tendency for the corded drills to be more popular because many users think they deliver more power, but chances are they have tried some of the small cordless drills that average from 6 volts to 18 volts. Those that are professional carpenters realize there is a large difference with 24V drills, when it comes to more power, better efficiency and better torque strength.
Innovative shock reduction systems are being built into some of the better models of 24V drills and they are lighter weight, yet capable of delivering 1.7 feet/pounds of impact energy, which is powerful enough for most jobs. Of course, there are many different types of tasks and sometimes, a smaller drill is perfectly capable. When you don't have a power source nearby, you can use 24V drills just about anywhere and most of them come with two-24V batteries and a 1-hour charger, so you can switch out to a second battery for constant use.
Other reasons that some prefer cordless drills is they will have a variable speed trigger so you can vary the speed, when you are screwing in a screw, and an adjustable clutch mechanism allows you to set the torque for proper strength, when you have bigger screws that need to go into harder materials, for example. In addition, you can find models of 24V cordless drills that have a keyless chuck, so you can change the drill bits by hand, quickly and easily. There are several different brands to choose from that feature other advantages that aren't shared by all models. Prices can vary, but you want to be sure to check the reputation of the manufacturer and realize that you may need to pay a little more for the best cordless drills, but it is well worth it in the long run.
The main disadvantage of 24V drills over smaller volt cordless models or the drills that are corded is that these larger and more powerful drills weigh more in comparison. Most of them will usually weigh a little over twenty pounds, which isn't as noticeable on small jobs, but those that are using them for larger remodeling and construction jobs can experience arm fatigue, after prolonged use.
On the other hand, there are those that point out they are being built in much lighter weights as the technology advances and batteries are improved in efficiency and made in lighter weights. There are many that can get by with 18 volt drills, but those that need more power and better strength will appreciate what the larger 24V drills can offer, when completing the jobs.
