Title: are hammer drills worth it for concrete drilling?
Post by: Marty Champions on December 16, 2013, 06:18:26 AM
i dont wanna buy one sense i dont have to drill into concrete that often , and i dont want another tool around. im thinking using just my regular drill and bit then occasionally hammering in a nail to go deeper and accurate

i hear with hammer drills you also dont always get a straight drive through the concrete wich could fuck up your anchor placement afterwords

I know nothing about hammer drills but having the right tool for the right job makes a load of difference. Mayne rent one when you have jobs that call for it?

Bosch hammer drill is the best to get.  Don't drill with a regular drill because it will fuck up the drill and the bit.

If you only have to drill holes 1/4 or less in diameter then you probably don`t need one. I have a cordless drill with a hammer setting on it that I use for setting little anchors and other light stuff.

 If you are going through poured walls you will need one, I have also used mine to weaken floors before I bust them open with the sledge.

Love my Dewalt hammer drill. I can set it from regular to hammer, so there's versatility for a guy like me who only sometimes needs the hammer function.

I went old school and bought the corded one...just got frustrated with batteries going and what not. Yes, it's more a pain. But I just do work around the house...I have enough extension cords to get me what I want. And call me crazy, but I feel the corded drills pick up more power.

Someone said about the 1/4" or smaller holes...I would agree. You might want to have a few more masonry bits at those sizes if you're not going to use a hammer drill. Just in case their wear out or snap. Without a hammer function, the tendency is to put a bit more pressure on the bit, and those little bits can snap on you. If you don't have a backup, you're back in your truck driving across town the hardware store.

But yes, it's honestly worth it. I would recommend getting a drill with dual settings if you don't drill concrete that much. When you need to put a lot of holes into concrete, do you want to spend 20 minutes (hammer), or 40 minutes (regular)?

Good post.


I use my impact driver when drilling concrete. Works pretty good, I've got the rigid one.

For deeper shit, I use a cheap 1/2" drill from Harbor freight. High RPM and does the job.

The batteries are pretty good in these but it's definitely for light duty shit. If you're drilling 1/2"+ I would go with this for $80

Buy a corded sds hammer drill.
The difference in unreal compared to a shitty normal drill which will take 5x longer and burn through 2 bits per day.
I have a dewalt one and when fitting conservatorys and windows it goes straight through the steel reinforcement in the pvc and the brick/block in seconds.
No swapping bits ect.

This. For brick a standard hammer drill is ok.  For concrete you want SDS.

If most of your work is underfoot, get a heavier one (probably will be cheaper too) and it'll double as a light duty demo hammer.  If you're doing commercial ceilings or going into overhead concrete a lot then it's worth spending money on a 36v battery Hilti or Bosch, but 99% chance a mains powered mid priced SDS will do what you want unless you are a commercial ceilings contractor.

Any drill will meander in concrete to some degree as the aggregate in the crete kicks the bit around.  If you're using C-track then who cares.  If timber then pre-drill the wood and use your bore to keep the line.  

Don't use a twist drill into masonry unless you want to look like a complete ass, dull the bit almost instantly, and swear like a sailor.  They are designed for drilling metal.  Metal cuts by being shaved away.  Masonry requires percussion to pulverize it.  The only exception I can think of is cold fired bricks like you would get in a historic structure or non fired blocks like adobe, but even then I would use a hammer bit without percussion.  Concrete, forget it.  You won't touch a high mpa concrete without percussion.

I've been using ramset chem anchor for the first time.  Amazing product if you're hanging off soft stuff.

What's the job, John?  Partition wall?

Buy a cheap hammer drill then return it when you're done (if you're only using it once)

A piece of wire or plastic zip tie inserted beside your fastener will keep it from moving, assuming you use the correct size bit relative to your fastener.

Hammer drills are the only way to go drilling concrete.  If you have trouble with control, be sure to get one with two handles.  Use goggles and dust mask.

Having broken up some concrete in my day (rerouted the plumbing in a basement of a house I once owned), I recommend you use a hammer drill unless the project is really small. Don't they have equipment rentals where you live? I bet you could rent one from Home Depot.

nope just laying a metal tac strips  over some tiles in a door way lol i only need to go about an inch deep, so what about just using a masonry bit on a normal drill (not a hammer drill) going an inch deep . yes i already made a cock out of myself breaking the 5/32 bit (non masonry bit) in about a minite

out of all the resedentials i deal with i never have to do any masonry or concrete im an amateur at this stuff

I think I drilled tile (glued in place) once.  I probably did use a twist drill, lol, or maybe a masonry bit w/o hammer.  I think different tiles need different treatment.  Porcelain would probably crack.  There are drills just for tiles.  Never used one tho.

Do you mean it's a threshold strip?  Resi maintenance work?  I'd probably just glue it and go home early.  You'd want some glue under it anyway to stop it clacking in between fixing points, so I say never mind about the fixings at all.  Fuck it.  It's already on the floor.  Where's it gonna fall?  Idk what's most suitable but liquid nails sticks to everything and epoxys are very serious and you could walk across it within minutes.  

i cant seem to mix sakrete mortar/stucco type s properly either it always dusts off like a little bitch even though i followed directions to the fucking t- on the bag  ::)

Cement needs to set (undergo hydration) before it dries out or you get a chalky result.  Most people fail to understand that drying and setting are two different things.  It will set properly if you keep water in it like this:

1. If you're unaccustomed to plasters and stucco, you're probably spreading it too thin.  Nothing less than 3/8" per coat will do.  (If a patch job doesn't afford you 3/8 depth you can get away with less using rapid set on a wet wall.)  You can try laying it on 3/16", letting it firm up for just a few minutes, knocking down high spots, and then doubling up to reach 3/8.  If you're going to darby it wet then hit your double up coat fast, before it firms up.  Most guys here dry rule.  The US seems to favor wet rule darby.  Set up wood or metal screed strips to guide the rule if you're working on an area bigger than your rule's span until you're so good you don't need 'em anymore.

2. Wet the wall.  Dry brick will suck all the water out of your mix and fuck it up.  In hot weather wet it more than once before troweling on.  Don't plaster in direct sun or high hot wind if you can avoid it by doing it at another time of day.  Once the wall is done, and the mix is set, spray the wall again to add yet more water.  They call it wet curing.  Applies to concrete slabs as well as cement plasters.  Non-thirsty substrates are another matter.

3. Use a good quality 'just add water' product, which you probably already are.  They have 'redispersible powders' like acrylic for bond, methyl cellulose ether for thixotropy and water retention, starches (from potato, true story!) for improved hang, etc.  Making your own from sand, cement, and lime is ok but workability and open time is much improved with commercial admixtures, and you don't have to worry about mix ratios, sand granule gradation, or clay content with a ready to go bagged mix.

Do you mean it's a threshold strip?  Resi maintenance work?  I'd probably just glue it and go home early.  You'd want some glue under it anyway to stop it clacking in between fixing points, so I say never mind about the fixings at all.  Fuck it.  It's already on the floor.  Where's it gonna fall?  Idk what's most suitable but liquid nails sticks to everything and epoxys are very serious and you could walk across it within minutes.  

Cement needs to set (undergo hydration) before it dries out or you get a chalky result.  Most people fail to understand that drying and setting are two different things.  It will set properly if you keep water in it like this:

1. If you're unaccustomed to plasters and stucco, you're probably spreading it too thin.  Nothing less than 3/8" per coat will do.  (If a patch job doesn't afford you 3/8 depth you can get away with less using rapid set on a wet wall.)  You can try laying it on 3/16", letting it firm up for just a few minutes, knocking down high spots, and then doubling up to reach 3/8.  If you're going to darby it wet then hit your double up coat fast, before it firms up.  Most guys here dry rule.  The US seems to favor wet rule darby.  Set up wood or metal screed strips to guide the rule if you're working on an area bigger than your rule's span until you're so good you don't need 'em anymore.

2. Wet the wall.  Dry brick will suck all the water out of your mix and fuck it up.  In hot weather wet it more than once before troweling on.  Don't plaster in direct sun or high hot wind if you can avoid it by doing it at another time of day.  Once the wall is done, and the mix is set, spray the wall again to add yet more water.  They call it wet curing.  Applies to concrete slabs as well as cement plasters.  Non-thirsty substrates are another matter.

3. Use a good quality 'just add water' product, which you probably already are.  They have 'redispersible powders' like acrylic for bond, methyl cellulose ether for thixotropy and water retention, starches (from potato, true story!) for improved hang, etc.  Making your own from sand, cement, and lime is ok but workability and open time is much improved with commercial admixtures, and you don't have to worry about mix ratios, sand granule gradation, or clay content with a ready to go bagged mix.

The batteries are pretty good in these but it's definitely for light duty shit. If you're drilling 1/2"+ I would go with this for $80

I'm here to help and never post my likeness on the internet.  

That's just for sand/cement, sand/cement/lime, and to some degree for historic lime/sand stuff onto traditional masonry like brick.  Acrylics like Dryvit don't go on thick so you might find them useful for low build skims.  Modern substrates like cement sheet, concrete panel, AAC block, styrene, SIPs, etc have their own considerations.

Rent 1 if its only for a single use or try Craigslist for used tools possibly. A decent brand shouldn't set you back too much and you can get the corded one that has the switch for on/off hammer mode. I am cheap and run to my dad's tool shed and borrow his dewalt. If I keep it long enough he will forget he has one and buy a new one..

Depending on the depth and layout of the concrete, I wouldn't be beating a nail in it so to reducing the possibility of cracking if you beat it too hard. Use the right tool!
