Cordless vs. Corded Drills

The debate on whether to settle for a cordless or corded drill is common in the HVAC industry. Each of these types of drills has its own pros and cons. Nonetheless, to settle for the best choice, you’ll need to consider your needs. Additionally, you must purchase a drill that will last a long time.

The following are some of the advantages and disadvantages of using cordless drills over the conventional ones:


On top of the falling and tripping hazards extension cords pose, they also pose electrocution risks. While chances of electrocution might be slight, by using a cordless drill, you can eliminate the probability of steel blades cutting through the live wires. Additionally, with cordless drills, you don’t have to be worried about electrical wires being overly exposed because the protective wear tends to wear away over time.

Effortless Climbing

Cordless drills allow you to work from elevated positions more safely and easier. The last thing you’ll have to worry about is tripping and/or becoming entangled in extension cords when you’re working on a roof or ladder.


Most if not all cordless drills feature powerful motors. With such motors, there’s no limit to the kind of project you can handle. It’s possible to work on all projects.

Some of the other advantages of using cordless drills over their traditional counterparts include versatility, functionality, accuracy, and speed.

Power Supply

Power can run out on a job thus jeopardizing your project deadlines.


Lower torque means that the drill is less efficient. It’s very hard to find cordless rotary-hammer drills with ample torque.


Clearly, the advantages of cordless drills outweigh those of corded ones. When in the market for the best cordless drills, it’s important to conduct extensive research. By doing that, you’ll be able to settle for nothing short of the best. If you’ve been looking for an effective machine, feel free to choose from any of the above five ones. You’ll not regret it.
