How much faster Rotary Hammer vs. my Hammer Drill


I have a 7.5 amp motor hammer drill. It takes me approximately 45 minutes to drill a 3/8" hole 2.5" deep into some beach stones.
My question is . . .
How much less time would it take me to drill the same hole using a 5.2 Amp SDS Plus Rotary Hammer, 2920 blows per minute?

TIA,
Kurango

P.S. It only takes a few seconds to drill same hole in concrete, using my hammer drill.

Get the drill, a stop watch and time yourself, and then you will know the answer.

I have the stop watch, that's how I figured the time it took for the hammer drill.

I am trying to figure out if it is worth my wild to buy the rotary hammer.

I have been using a Bosch blue granite hammer drill bit, drilling slow, in water, so I won't wear out the bit.

Come on guys, you can give me some better educated guess answers!
Just tell me . . . for example

It will cut your time by approximately 10 minutes? or It will take you approximately 75% less time with a rotary hammer?

I really don't know the answer but maybe rent the rotary for 1/2 day to see. Let us know what you find out.

I use a older German made bosch 1224 bulldog. I got my friend, the mechanic( who now works for the local water/sewer company, a hitachi d handle rotary. The bosch is a little more refined BUT I can't believe how hard those Hitachis hit! Blows the bosch away. Very fast drilling and/ or chiseling.

I have to go to the way-back machine for this one since I don't use hammer drills that often anymore. But back in the early 80s when I was working as a CATV installer and using a normal Milwaukee hammer drill on a daily basis, I would occasionally rent a rotary hammer drill if I knew I was going to be drilling numerous larger holes (5/8 to 1") through concrete or hard brick. It was a night-and-day difference. The rotary hammer would just eat through stuff. I would have bought one but they were crazy expensive back then.

What I am hearing is . . .

hammer drills are antiquated so no one here ever uses one, so no one can tell me if it would make much of a difference.

No one ever has a reason to drill a 3/8" (larger or smaller) hole 2 1/2" deep in solid rock, so no one knows?

I do appreciate the better answers.

Thanks, Kathi

I'd go to Home Depot, purchase the Bosch Bull Dog, appropriate bit, and try it yourself. If it works then keep the rotary hammer and if it's not to your liking then return it.

That's not what I hear at all. What I hear is the rotary hammer is a lot better.

I've got limited experience with both types of drills but my neighbor has an arsenal of tools which he is always willing to lend out to me. I borrowed the Bosch Bulldog to drill a dozen holes in concrete and blew thru the holes absolutely quicker than the corded hammer drill.

We call drills with hammering action a hammer drill. A chipping machine with the option to bore holes is called a rotary hammer. It all comes down to BPM, tool weight, and quality of the machine itself. The answer your looking for can only be had in a head to head comparison. My suggestion would be to go to YouTube and check out some videos on the machine you're interested in.

Good luck.
