Comparing 12-Volt vs 18-Volt Cordless Drills & Tools

Are you looking for the biggest and most powerful cordless drill and tools? Or are you after something compact and lightweight? Do you want something that will charge quickly? Or is the price of the tool making the decision for you?

You see, there are so many factors to consider when choosing tools. To help you make the best choice, check out the comparison below. It will discuss the differences in features between 12-volt and 18-volt cordless drills and tools.

Power

What kind of tasks will you be doing with your cordless drills and tools?

If you will be using yours to do heavy-duty high-stress tasks, then you will need tools with 18 volts. But what if you will only use your cordless drill or tools to do odd jobs around the home? Then a 12-volts will be perfectly suited for you.

For your everyday jobs, 12-volt drills and tools are great. This is because they provide you with ample power to complete the tasks successfully without the added bulk of a larger tool. But if you are going to do any rigorous work, you may be better off with more powerful tools.

Weight

I get it. Tools are tools, we expect them to be a little heavy. But do you spend a lot of time working in awkward spaces or even working in spaces above you? Then the weight of your tools is an issue. To avoid wrist fatigue and keep a steady hand, you will need lighter tools.

12-volt cordless drills and tools tend to be much lighter than those with 18-volts.

If you spend a lot of time working in tight, hard-to-reach spaces, you should opt for 12-volt tools. But, if you know you won’t be using your cordless drill and tools for lengthy periods, go for 18-volts.

Some 18-volt cordless drills for example are significantly heavier than 12-volt drills. Some of them are 1 pound heavier or more than their 12-volt counterparts. This weight difference can really be of value during a long day of drilling.

Size

How much room is there in your tool kit? If you’re like me then I’m sure you’d agree that there’s never enough! That’s why I like to opt for smaller tools. I do this so that I can fit a wider variety of tools in my toolbox to take with me on a job.

If you are looking for a small cordless drill and tools, you should choose within the 12-volt range. If you’re not limited by how much you can carry, choose from the 18-volt range.

Charge Time

There’s nothing worse than waiting for cordless tools to fully charge. The wait seems to be agonizing, and time doesn’t seem to budge when there’s a job waiting that you’re itching to start.

12-volt cordless drills and tools charge the fastest. This is because their batteries are smaller so they charge faster. If you are often charging your tools in a hurry, the 12-volt range will be best suited to you.

Run-Time

Have you ever been in the middle of a job when the battery on your cordless tool ran flat? Now that’s a horrible mix of both frustrating and time-consuming. So let’s get you kitted out with a cordless drill or tool with a long run-time.

18-volt cordless drills and tools have a longer run-time. They can drive heavier loads without slowing down the battery. If you have a long day of work ahead of you, 18-volt tools will be the best match.

Price

Cordless drills and tools are expensive. Are you looking to save a little money?

12-volt cordless drills and tools are cheaper than those with 18-volts. And the price difference is quite something. The great thing about 12-volt tools is that you get a great tool at a reasonable price. What more could you ask for?
