Power Drills vs. Impact Drivers: What’s the Difference?

When it comes to home improvement projects, a power drill is one of the most common tools you’ll need. But an impact driver is perhaps an upgraded version that you should consider adding to your arsenal.

Power drills and impact drivers are similar tools: both look a lot alike, and they both are able to drive screws into different materials. However, impact drivers make the work a lot easier.

What Impact Drivers Do

Here’s the main difference: Impact drivers utilize the same rotational motion that power drills use, but as you’re driving in a screw, impact drivers also mix in a hammering action that not only hammers down, but sideways. This makes it way easier to drive screws into tough materials, and it prevents the drive bit from slipping off the screw head, which could potentially strip the head and ruin the screw.

If you’ve ever heard an impact driver in action, then you’ve probably noticed this in the form of a really loud, repetitive clicking noise that it makes as it’s driving in a screw. That’s the noise of the hammering action, and it occurs dozens of times per second, depending on how fast you’re driving in the screw.

With a power drill, you’d normally have to apply a lot of pressure in order to prevent the drive bit from slipping, but the hammering action of impact drivers mostly prevents this, and all you have to do is apply enough pressure to keep the screw guided and on point.

Impact drivers are also great for removing stubborn screws or bolts when reversing the spin direction. The hammering action can make…
