This difference in cell count results in several key performance differences. 18v cordless drills have longer run times than their 14.4v counterparts. They also tend to be heavier and more expensive.

Gearbox Difference

The gearbox allows the drill to produce different torque or twisting forces. It is responsible for regulating the speed of the drill bit, and 18v drills typically have a more powerful gearbox than their 14.4v counterparts.

This means that 18v drills can drill through more rigid materials faster, making them a better choice for heavier-duty jobs.

Amp Hour Rating

Compared to 14.4v and 18v cordless drills, the 18v models typically have a higher amp hour rating. The amps-hour rating indicates the amount of time the drill can run on a single battery charge.

A higher amp hour rating means that the drill will be able to work for longer before needing to be recharged. This means that 18v cordless drills can run for longer on a single charge, allowing them to handle heavy-duty applications.


Generally, 18v cordless drills tend to be more expensive than 14.4v cordless drills because they offer more power and performance. However, if you’re looking for a powerful drill that can perform quickly, an 18v cordless drill is the way to go.

Conversely, if you’re on a budget or don’t need all the extra power, 14.4v cordless drills will work just fine. Another thing is that 18v cordless drills usually come with more accessories than 14.4v cordless drills, so you’ll need to factor that into your purchase decision as well.

These are key things to remember when comparing 18v and 14.4v cordless drills. Ultimately, it’s up to you to decide which type of drill is right for your needs and budget. But if you consider all these factors, you’ll find the perfect drill for your next project.
