Diference between drill and hammer drill

[nb34]

Hi, new in the forum, and i have a question:


In wood and steel, ¿What is the diference between drill and hammer drill?


For example in this two models from makita, the drill and the hammer drill have the same power (720w), same gear reduction,
and most parts are the same:

Thanks

A hammer drill has an impact motion in addition to a rotational motion. It's used for masonry, the bit doesn't so much cut as pulverizes the material. It's not to be confused with an impact driver or impact wrench, which only has a rotational motion.

In other words, you will never use a "hammer drill" to drill wood or metal. It's used for concrete and similar masonry material. If you plan on drilling metal/wood and masonry on occasion, you can buy a drill that has the hammer option. It's not quite as strong as a full on "hammer drill" however.

Also, I'm pretty sure those pictures are the exact same for both drills, but not sure both actually look like that. Usually regular drills don't come with the depth gauge, but I could be wrong.

Drill - Making a hole in wood, steel, aluminum, plastic, etc.

Impact - Spinning something that is stuck (lugs, nuts, bolts, screws)

Hammer - Making a hole in Masonry, concrete, block, stone.

Now... making a hole in TILE... is tricky... to not crack the tile. I have used hammer drills with diamond bits... and masonry bits as well. DO NOT LEAN in like you would other masonry holes.

For glass... just use "Drill mode" with a diamond bit.

Ayuh,.... The difference is, if ya got a hammer drill, you can drill 'bout anything,....

If ya don't have the hammer drill option, No way yer gonna drill concrete or rock,....

Thanks for answering.
But my question is no about the use the hammer function in steel or wood ...

It's about the difference between the drill and the hammerdrill with hammer function disabled (only rotation) in wood and steel, for example here

the dp4011 (drill) is used in a drill stand.


If i use the hp2051 (hammerdrill) in rotation mode only, instead the dp4011, is there any difference?

Thanks

No difference.

 

[PelicanPines]

No difference.

+1... no diff... other than the hammer drill may be heavier.

Are you trying to decide which one to buy, under the assumption that you do not need the hammer function?

In the case of a corded drill, the hammer probably adds a lot of weight and length to the drill. Both bad things. I've also seen someone accidentally bump the hammer switch on a corded Hitachi at work, and trash a drill bit when it touched steel. A non-hammer model would not have been able to do this.

In my cordless drills, I have usually gone for the hammer models, if they don't add much length or weight. The reason is that the hammer version of the same drill usually comes with a better gearbox and/or chuck.

I heard recently the acceptable run-out spec on a hammer drill may be much higher. My terminology is likely wrong, but apparently since the chuck can't be directly driven by the spindle in order to allow the hammer action, it's nearly impossible to build it without some measure of wobble. I've had noticeable wobble in both my Dewalt and Milwaukee hammer drills, both came back from warranty service with no discernable difference. I've been told I wouldn't experience that in a non-hammer version.

The hammer drill will normally have a standard drill function setting and also a hammer drill setting. When you have it on the hammer drill setting it will drill and hammer at the same time. This action along with a special carbide tipped blade works well for drilling small (1/4" or smaller) holes in concrete. They can drill larger holes, but not very efficiently.
I hardly ever purchase a drill anymore that does not also have the hammer drill option.
