I'm no expert, but in these parts the terms are used interchangeably for the same tool (we say roto-hammer instead of rotary hammer).

I'm inspired to buy my first impact driver.

I hate these threads where I end up buying something I didn't know I "needed."  Who started this, anyway?    [ar15]

I just had a friend stop buy that works at a tire shop. He stopped in to pull the driveshaft out of his truck. We might have been drinking when we twisted it in half.

He had his Dewalt impact driver with him that he uses all day six days a week.

I have another friend with a tire shop here in town. I know he went to using two impact drivers instead of having air hoses everywhere. I'll stop in and ask him what he has and how he likes them. I think he bought two brands to compare.

OK, what's the difference between an impact driver and a hammer drill?

Is the impact driver a rotary hammer motion, while the hammer drill is linear along the length of the bit?

Yes.

A hammer drill normally has a way to disable the hammer function and just be a drill.  A rotary hammer just does that one thing. They also tend to be bigger and more powerful,  as well as come in spline shaft varieties.  (SDS+ and the like)

My hammer drill has exactly that... Turn off, and it's a drill. Turn to 1, and you hammer drill. Turn to 2 and you REALLY hammer drill. It's distinctly uncomfortable to use on setting 2 for much more than a couple of minutes because of the vibration.

Still, can't complain about an all metal body 1/2" hammer drill for free.

I was working on an old contract and we had an upright cabinet in the one conference room that hadn't been opened for years. The facility guy said let's open it (it was locked). We picked the lock and it was full of tools with absolutely no indication of ownership.

So, we split them up. I got the hammer drill and a nice fish tape. Someone else took a nice half inch socket set with the ratchet, someone else took some electrical testing equipment, etc.

That drill has more than paid for itself over the years.  :rofl:

Here's a short video explaining drill vs impact driver vs impact wrench vs hammer drill:

First video I've seen by that guy, he is to the point.  I've seen too many videos where someone takes 20 minutes to say something that could have been said in 4.
