Many people are seeking to find out the differences between cordless and corded drills. Mobility is a clear difference when it comes to the cordless version of the drill. Placing a battery into a cordless drill will allow you to roam freely to your heart's content or until the battery has lost its charge; whichever comes first. Cordless drills are reliant on electricity and their mobility is typically limited by the length of the extension cord being used.

Some of the differences between corded and cordless drills will be explored in this article. This will include the advantages and disadvantages of each version, RPM's and max power output. As such, if you are attempting to determine which one to purchase, this should provide insight and help with the decision-making process.

Let us explore the max power outputs of a few cordless and corded drills. It could also clear up certain misconceptions about watts, volts, amps, torque, and power. Corded drills are powered by the normal 110-volt power supply of most homes and garages. The maximum power output will depend on the size of the electric motor, which is measured in amps. A corded drill that has a 7-amp motor, for example, has a max power production of 770 watts.

Watts, which is the maximum power output, is not really the most important thing to think about when drills are being compared. Torque and speed are the most essential considerations. Torque, which is measured in inch-pounds, relates to the level of rotational umph behind the spin. Speed, which is measured in RPM is merely how fast the drill rotates.

These days, many of the top-quality cordless drills are equipped to produce some tremendously impressive speed and torque from their 20 or 18-volt batteries. In addition, they will supply all the power needed for use around the home. An interesting calculation has been used by DeWalt called MWO (max watts out) to designate their cordless drills with a max power value. However, as was established, the real proof of power is the torque and speed and corded drills have the capacity to pack power because of their bigger power supply.

Additional Considerations

Weight, Size and Handling

Corded drills do not need bulky, heavy batteries to function and as such, they are typically much smaller, leaner and lighter when compared to cordless drills. As a result, the majority of professionals typically take a corded drill with them to jobsites, in the event they are required to reach into a tight spot in which bulky cordless drills cannot fit.


It is the belief of a number of individuals that the wickedest fate a battery can suffer is being left to sit idle for an extended period of time. If you are looking for a drill and you know it will not be used a lot, the wiser choice would be to buy a corded drill. Even when they are used often, batteries will not last forever. The batteries can be expected to last a few good years; however, you will not get the decades of use that you can be supplied by corded drills.

Mobility and Handiness

Not having the hindrance or limitation of a power cord is obviously the primary benefit cordless drills have over their corded counterparts. However, are also constrained by the extent of the charge that is allowed by the battery. It is simply a give and take matter.

The best decision you make will largely depend on factors such as your specific needs for a drill. The applications required to successfully complete your project is something that should be carefully considered as well. Having both the corded and cordless versions of the drill, if your budget permits, is the best possible scenario. The ability to grab the dependable corded drill, when required is great and there is certainly no substituting the convenience of the best cordless drill.

Bottom Line

Typically, corded drills are more powerful, leaner and lighter than their cordless competition. They also restrict mobility and are less convenient and noisier. The experience of the best cordless drill should never be undermined. However, they are heavier, bulkier, have clear power restrictions and a more limited lifespan.
