You don't need a hammer drill to drill into concrete, brick, or stone. Concrete is the hardest of the materials, and a regular drill will work just fine; it's just a bit slower, and you will have to apply more force.
Any time you plan to use concrete anchors or concrete screws, you will first need to drill the appropriately sized hole into the concrete So first, you need the correct size masonry drill bit, then a decent quality power drill.
From there, simply mark the location, carefully get the hole started, then drill just like you'd drill into any other surface.
Once you have the hole drilled about 1/4" deeper than the anchor or screw you'll be using, clean out the hole thoroughly and then pound in the anchor or screw in the tapcon screw.

Having drilled thousands of holes in masonry I can say that having the right tool for the job makes things go much smoother and quicker, and that would be with a rotary hammer drill. Yes you can use a regular drill with a masonry bit, and as commented on, you're going to have to use some physical pressure to get the job done. I believe the point is, if you only need a few holes for a specific install then it isn't necessary to blow a bunch of money for another tool. However, if you're doing this in a repetitive fashion then save your body and energy and use the correct tool for the job and get the job done more efficiently.
Agreed
Also depends on the material you are drilling. I know this video is about concrete, but a regular drill even with a masonry bit would just simply not work on certain brick and concrete that is extra hard, old brick especially. There are some materials that requires that hammering effect which chips away at the material as opposed to just drilling it.
Can you please share what's a good hammer drill to buy and drill bit ( including manufacturer) will be greatly appreciated?
@@anilg28 sorry, I missed your inquiry, I would recommend an SDS hammer drill. I have a Dewalt myself but there's lots of them out there, corded and battery models. Folks tend to be brand loyal so take a look at your favorite first. On some of the SDS drills you can get attachments that will do things like drive a ground rod in the ground,.. very helpful for electricians.
Not to mention the added stress put on the regular drill motor, battery and gears. For a hole or two probably okay but anything more would be not good.
Drill with a smaller hole because it’ll be easier going through the concrete, then move up to the larger drill bit. It takes less toll on your drill,especially if it’s cordless.
Thanks for the tip.
Do you also recommend using water as a lubricant?
@@zanderesp4295probably just for indoors
Pilot holes? No shit
Really stupid question but for clarification, you mean you would recommend drilling a smaller bit first and then use the size for your anchor? I ask only because I have yet to see it mentioned for masonry drilling but of course it's mentioned for wood drilling...since brick can be more brittle some times, as a newb DIYer I don't know when it comes to brick
Good luck with this approach. I tried this when I moved from my old home into my current one. In the old house I could easily drill into the wall with a normal (corded) drill and a masonry bit. Tried that in the new one, took me an hour, I got about 5 mm in and I had to get a new masonry bit. I also bought a hammerdrill and it took me 5 seconds.
This same wall, I hired someone to drill a hole for the kitchen ventilation. He came, and then used a huge diamondcore drill with watercooling that he bolted on the wall with 4 separate bolts. Still took him 5 minutes to get through the first wall at full power. Yeah, my walls are a bit of an outlier, but still. If you find yourself with really hard concrete, get a hammer drill. It's way easier.
Yes, and also hire someone making a living out of this as you correctly did.
One of the best presentations of any DIYer that I've seen.
It’s a good idea to mark the hole's centre position with a cross that’s a bit larger than the drill bit. That way, if the drill drifts at the start you won’t loose the correct centre position if the drill moves a little and scrubs some of the mark out.
Good tip. Thanks
I did this experiment on my own as I did not want to go out an buy a hammer drill if I didn't need it. After going through 2 batteries and not even getting through 1 1/2 holes I decided to buy a drill with the hammer feature. It was a night and day difference. It took me just 5 minutes to drill the rest of the holes I needed.
Glad you got it figured out! Thanks for commenting.
Thanks for this! First time home owner with a ton of things that need to be done, so this super helpful!
Excellent job on this video! Very helpful.
This was one of the most helpful videos. I used the same drill your using to install a sturdy ground anchor, the cement was almost as easy as wood. At first I tried a cheap bit - it overheated and barely made the hole. Then I switched to a quality bit - HUGE difference. I'm also 240 which probably helped - thank you for saving me from buying an overpowered tool that I'd never use.
You’re welcome!
You could have rented the drill with a bit for like $35 or less probably.
I already had the drill ...@@berzerkbankie1342
Thank you so much, so very helpful, especially when you do your own DIY.❤
The difference is wear and tear on your cordless. If you’re doing lots of holes you will burn up the cordless, a good sds hammer drill will last years with daily use. For a home owner this is fine, but for me, a 25 year veteran in structural concrete form work, it’s not even comparable.
Makes sense.
Yes...I'm sure, he talking about in a pinch dude...he said if you don't have a hammer drill or can't afford it...geez
No kidding! I burn up at least 10 cordless drills a year from drilling concrete with them. Happens all the time. All my coworkers have the same complaint. A cordless drill will only last for about 1,000 holes before it burns up.
@@StayHandy Stop being a stupid p.ick. You NEED a rotary hammer not a regular hammer dill to drill concrete and even brick.
Damn right buddy
Quality bits are a must! Thanks
Yes, they definitely help!
Thank you! this helps a bunch.
Thanks for this video, I was looking for something like this a while back and this would have helped. It helps now!
Glad to hear it!
I've used masonry drills on many occasions and have to use one again today. SO, being a terrible procrastinator, I thought I'd have a look at TH-cam for how to use a masonry drill, before starting the job. It turned out well because I watched this video. I'd not initiated the hole on non-hammer before, so I'll give that a go. And I'd never considered not using a hammer drill for masonry bits, so that's a lesson too. Anyway, very good video, it's now 10 minutes later, 12 mid-day where I am, meaning it's lunch time. I'll now start my job after lunch. Thanks very much for providing an excellent distraction!!! I've got to go now because my wife is screaming at me to get off the computer...
Haha, enjoy the new tips.
Thanks for that side by side comparison. Good to know!
Glad it was helpful!
You can keep a cup or bottle of water to pour water around and into the hole to keep the bit cool which helps with wear.
Great tip!
Great video. Thx!
I came here because I bought a 20v cordless drill and it just got delivered today. Never used a drill until a few hours ago and I want to mount a TV on my concrete wall. I'm giving this a try tomorrow and I pray it works out and I don't phuqq myself up 😂 fingers crossed 🤞🏼
How’d it go?
thanks for the tip!
Sure thing!
thanks, very helpful
You're welcome!
Thanks for the tip about marking holes where you want them to be. I was randomly drilling holes all over and didn't understand why the bracket didn't line up.
Haha
I also use Bosch multi construction bits. Work really well with battery drill, and much of the time don't need to use hammer function anyway.
You saved me $150-$200. I was about to go buy the hammer drill, however your video gave me the confidence to get the work done with driver drill!! Thank you, really appreciate your advice!!🍻
I'm so glad to hear it.
you would still want a hammer drill, if you have a big project, eventually your cordless drill will crap out.
If you're going to spend the money skip the hammer drill and get a small sds plus rotary hammer. Drill holes faster and you can switch off the rotation and use chisel bits
I’m having a hard time getting the provided masonry drill bit that came with concrete screws to drill trough an outdoor brick area. Using a 20v dewalt max. I tried applying a lot of force into the drill but hole is like not even halfway
You can have a hammer drill driver
Dan, thanks for your instructional video. Really appreciate it. Can you also share what anchor (including picture) would use for a 6" thick cement deck for a storage shed in the back yard. Any feed back appreciated.
Nice drill!
I resisted getting a hammer drill for a long time. I needed to drill into concrete on occasion but not often enough that I thought it justified buying a hammer drill. I was wrong. Drilling into concrete is fun with the right kind of drill. More importantly, if you intend to use Red Head anchors you need a hole fairly close to cylindrical. The ragged hole produced by a non hammer drill may not be smooth enough. It is true that for smaller holes, maybe less than 3/16 of an inch a regular drill works OK. For 3/8 inch holes a regular drill might work if you are on Mars and can't get a hammer drill. But, if you're on Mars, you need to drill a half inch hole or larger into concrete and you can't get a hammer drill, just give up and enjoy the time you have left.
thanks God bless
Option 3: Rotary Hammer plus SDS bits. The SDS bits are splined which allows for a superior hammering action. Can also be used as a mini breaker (with appropriate chisel bits). Well worth the investment.
Yeah, now its not expensive to buy off brand one. China makes millions of them, and its completely ok if you don't use it as professional tool every day.
great video
Thanks!
If you want to get more than 2 or three holes from your drill bit, have a bucket of water handy, and dip the drill bit into it every so often. This keeps the bit from over heating and loosing its temper. I also use a cold chisel punch to start my hole. This keeps the drill bit from wondering. Simply place the punch in the correct location and smack it with a hammer a couple of times. Also, if you are drilling into brick or concrete block, it is best to not use the hammer function, and it will blow out the back of the block like an explosion.
Good tips
Hi, I believe that the proper drill for this job would be a SDS hammer. It is significantly faster then a hammer drill and it will take about 3-4 seconds to drill a hole.
Thank you. Just need 4 holes for a water hose mount. I dont need anything fancy. Im a country gurl that lives and breathes outdoors handy work around my home. Will do just fine for me. Thank you for the 2 comparisons. Great video. Really great.😊
I have a fish pond with 2 closed off concrete walls on the side that trap rain water. I was gonna get a saw but I think I can makensome drainage holes now with the right drill bit. Thank you! Hopefully this saved me some fundsol
Go for it!
Good video
thanks.
Gr8 info
To clear the holes and get rid of dust you can insert a 1-2ft.-long piece of 1/4" pex tubing and simply blow all the dust out. Much easier and faster than vacuuming ;) Thanks for the videos!
That’s a good tip. Thanks
Or suck out the dust with a mc Donald's straw
It tastes better than mcdonalds toooo
@@d.k.1394 lol almost true.
My ways to clean holes
1) Hold the straw airtight with your hand over the intake of the vacuum cleaner.
2) Blow compressed air from a spray, stronger than a blow-out pump, holding the vacuum at the hole's exit.
3) Same with a hole-cleaning brush.
Thank you so much for sharing this. I only need to drill a couple holes to install a handrail and didn’t feel like purchasing a hammer drill.
You're welcome!
Tip: use a drinking straw to reach the bottom of the hole with the vacuum and clamp your hand around the vac nozzle and straw top.. it's way easier to get the dust out.
Thanks for the tip!
I have listened to this guy do presentations on how to start a businesses!
Were you on the recent webinar?
@@StayHandy fortunately, I signed up, but the link went to the wife and I missed it so, I listened to it after the fact.
subbed - good content
Thanks!
I had a project for a customer last fall that required me to drill several holes in very old concrete. After trying to use my regular drill and several bits later, I decided it would be much easier to rent a hammer drill and it was a wise decision for sure.
Sounds like it worked out in the wnd
@@StayHandy Yes, it did work-out in the end, but even with a hammer drill, it was still a chore to drill holes in the old concrete.
Concrete hardens with age.
A smart person evaluates the situation . If you find you require tools that shorten time on the job and you defo will use on many jobs then go buy that tool . I got my big rotary SDS hammer drill and that pounds big holes 24/7 . If I’m doing the odd hole then I’d use the cordless . If you doing these anchors all the time then go bigger than a powered small hand drill ,go for a big SDS , my Bosch I’ve had for twenty years and minimal maintenance( just brushes and a bit of grease ) and it’s punched holes through bank vaults ( 3.5 ‘ reinforced concrete) . No am not a bank robber , we turned an old bank into a dentists. Mad thing was I used a 3ft drill bit and still didn’t punch through
This video just in time for me! I need to drill four holes to anchor my lean metal shed, I’ve been considering to buy a rotary hammer drill since it’s what I saw in some other videos, but it’s kind of waste to buy a hammer drill just to use once. I’ll try if I can use the normal power drill to get it done after seeing this video!
Yes. Give it a try and if you absolutely need to, then buy a hammer drill.
If you haven’t bought a hammer drill yet… get one at Harbor Freight. They’re about $95 and if you’re gonna use it just once, it’s better than buying a brand name for triple that… at least this is what I did and was well worth it for my project.

Did it work?
Depends on the concrete. The concrete i had to drill had really hard rocks mixed in. At some point it stops drilling, the bit heats up and it wears out.
My concrete wall has small rocks in it. Will an expensive concrete drill get through that, or am i just out of luck?
@@edntzA hammer drill breaks those rocks and continues on. That, to me, is their greatest advantage.
Rebar in concrete is a drill bit killer, but special SDS drill bit exist that claims to go thrugh rebar like butter. What happens when you hit rebar is that the drill bit can not "eat" the metal and heat starts to build up and melts away the tip of the drill bit and you are toasted. What I have done a few times when I feel I had hit rebar, I take a regularly drill with a standard metal drill bit and sacrifice that drill bit to go thrugh the rebar.
For big holes, and a lot, you need a powerful hammer drill that takes SDS drill bits.
I came to look on how to drill into concrete because I am fixing my porch that has some loose decorative posting. I am only 105 lb lady, and I will try with my electric screw driver. I am afraid it may not work for me. I have to go get the masonry bit. I am hoping for the best since my holes are fairly small. The house former owner never secured these things, and they are a hazard. Thanks for the instructions!
Buying a good DeWalt SDS hammer drill was one of the great purchases of my entire idiotic tool collecting life. It all depends on how many holes you need to drill, how big the holes are, and how hard the concrete or stone is. I have drilled probably thousands of holes in masonry. You can definitely just use a regular drill with a good sharp masonry tool bit. Slow and dreary but it does work. The next step up is the basic hammer drill. They are a bit faster but also super loud and vibrate like you can hardly hold on to them. I wore out a really nice Bosch corded hammer drill so ended up buying this very sweet cordless DeWalt SDS rotary hammer. Cordless I say! OMG so fast, a fraction of the vibration, so much quieter you can actually not use ear protection, I am not kidding. Also it will just a hammer, miniature jackhammer which is fantastic. Constructed walls in my basement had to drill about 50 holes into very old concrete. It was a real true pleasure using this new drill. If you just need to drill a few holes on one random project then yeah go ahead and buy masonry drill bit and have at it. I can give you about 20 of em I don't need the cursed things I have all SDS kit now.
Thanks for the insight!
a protective eye gear is a must while drilling into concrete considering the dust and small particles
so first thing, i have a tight budget for hammer drill and im currently only using just regular drill...so with various of other comments here...well i personally think choose the tools that can be supported by ur budget..anyway the videos really did helped me to drill through concrete walls with regular drill and masonry bits...maybe in the future if my budget allow ill equip a new hammer drill soon...thanks
Yes you do ! New concrete is far easier to dril than many years old concrete. Many other factors come into play as well.
Make a video then.
Some old concrete that was poured back in the 20th century simply can't be drilled with a regular drill, especially larger holes. It has to do with the amount of crystalization within the concrete. New concrete that was made with high water content and allowed to dry very fast has lower crystalization and is more like styrofoam compared to old concrete. The concrete in this video looks newer and 'builder grade' (cheap and fast).
I used to do with a cordless no hammer drill for convenience, and now I’m straight getting an extra wired hammer drill. It does the work in seconds instead of minutes, and my neighbors prefer a short burst than a long wiring sound
That was very informative, thank you. I likes the tip about correcting the position of the hole.
Sometimes it’s a bit hard to put all your weight on the drill, though, like when you’re drilling high on the wall from a ladder, or in the ceiling. Recently I had to drill 6mm holes in the concrete ceiling and even a hammer drill didn’t do the trick, I had to use a rotary hammer.
Makes sense. Thanks for the added perspective.
Do not push at all
If yout using expanding anchors it doesn't matter what kind of drill but if your using tapcons your less likely to wallow out the hole with a hammer drill and the screws will hold better. Also if your not using a hammer drill your goi g to wear out the drill bit faster.
Thanks for the additional perspective, Chris!
Thanks for using the same model of drill i am looking to use. Lots of experience using sds and rotary hammer tools, but this job is independent and required only what i own. I know i can kill (3) 3/8" anchors at 3" dewp with my tool and not kill it
Purchasing cheap off brand sds+ rotary hammer drill is never bad idea.
Cheapest rotary hammer is infinitely more productive than hammer drill.
You have to put a lot of pressure to do anything with it and it will quickly wear out your drill and drill bit.
@@Georgggg the job went poorly. I spent 2x 5/32 bits to pilot, and 2x 1/4 bits to size the hole. Burnt, blued and destroyed all 4 bits. 5/16 x 2-1/4Tapcons failed, driver was stripping the heads off before they made it 1/4 depth. Went back for wedge anchors 1/4 x 2-1/4 and they performed.
Yeah... I was really missing the Bosch bulldog, or the DeWalt battery SDS, that I've used with other contractors... Rough day!!!
@@Georgggg to all readers: the harbor freight sds hammer would have been worthwhile for the labor I put in to the DeWalt drill with a 4ah battery
Really nice video. Can you comment on where you got that pergola? That's exactly what I'm looking for. Thank you!.
Got a cordless hammer drill from Aldi here in England, works great for going into concrete
Try the SDS version and it's way, way faster.
@@typhoontim125 yea that's the one
@@konstantine381 Great...Sds is on another level...and no loosening of the bits...and being from Aldi, incredible value.
If you're mounting a plate with multiple holes, use the plate as a jig to start the holes in correct orientation to each other after getting at least one accurately started by eye, marker and/or punch.
I was drilling holes into concrete last weekend and found the drill bit going blunt after the first hole a problem as I needed to drill 8 holes I was using a 5/16 masonry drill bit
You can drill a hole with out the hammer function however u will need to replace your bits quite often because the bit will overheat even while spraying water
Great video very informative for a novice. What make/brand drill bit do you use?
Thankyou
Look forward to your response 👍
Thank you for the video. Where did you purchase the pergola from? It looks very nice!
It depends on the concrete. If it's fresh concrete with lots of sand and no gravel, then it can be relatively easy to drill through. If it's decades-old concrete with lots of gravel then you'll want a hammer drill.
That's the best reason for a hammer drill, getting through rocks in the concrete without problems like the hole getting huge or having to stop to break each rock by hand.
Excellent informative video for this DIY guy and the simple project in mind. Thanks! One question. You don't use some sort of cement epoxy when installing the bolts?
👍😉👌
No
Thank you for this, highly appreciative. Thoughts on drilling into granite ?
Try it without the hammer function first, then if you need it, use the hammer function.
1. It is not really easy to drill to concrete WITHOUT the hammer function specially when drilling holes to the wall or concrete soffits. Try "applying" your own weight on those.
2. Forcing your cordless drill to this concrete, and then doing it several times, will wear down your battery even faster which will require you to charge more often. It is interesting to see how many holes the cordless drill without the hammer function can finish with one charge(considering the battery capacity, of course)
3. It is also interesting to know that hammer drills will make your work faster and more efficient in this kind of situation.
The hammer function is designed to some drills, corded or cordless, for a reason.
Sure the non-hammer drills will get the job done as seen in the video. But if you want efficiency(specially if you are drilling a lot of hiles on concrete), you may want to consider affording a hammer drill.
It is not that you don't need a hammer drill per se.
But it is about considering the right tools for the right job.
Right, you don't need a hammer drill if you consider your drill to be 'disposable'😂
Exactly. If I had less than two holes to drill and no hammer drill, I'd proceed carefully, cooling the bit frequently and using the bit as a chisel to break any rocks encountered by hand. If I had more holes than that to drill, I'd stop and get the right tool.
Hi, great video. For a similar project where I have to install a metal pole to anchor a sail shade to, how can I drill perfectly straight into the concrete at a 90 degree angle?
Either a drill press or a decent level of skill using a drill
how to insert the diamond coated milling bit to the drill?
Thanks for making this video. I have a hammer drill. One thing I ran into is there are gravel chips in the concrete. It seems once the drill hits these, the dril shifts away from the original hole a bit, and the result is out of three holes, only one lines up. Any advice? Many thanks Mike
if you are on a budget then what I would recommend is to buy a corded hammer drill. its not that expensive compared to a regular corded non hammer drill but makes a huge difference in my opinion because you cant always use your body weight in every situation. sometimes I drill way high up or in weird places where I cant use much of my body weight. And obviously if you are drilling multiple holes, you'll feel tired because you are also doing some of the work which the tool is not doing. Also bits gets duller quicker and less effective without a hammering action.
if your home is made using bricks and concrete then I suggest leaning towards a bigger rotary SDS type drill because those things works super well. They have much slower RPMs but the actual hammer effect is way higher. Since they spin slowly and have a better impact, the bits will last much longer as well. However these drills will use a different type of drill bits which you can slide in and you cant use other drill bits for example when drilling wood or metal without an adaptor. Most SDS drills will come with this adaptor but I think you can buy separately too. with most SDS type drills you can also select what you wanna do. you can just use the rotary action or just the hammer action or both at once. great if you wanna break up tile or small stuff like that.
if you got the money then what I recommend is to get a cordless normal drill + a SDS drill. owning just ONE drill is not that ideal because lets say you just got the SDS drill, then if you wanna drill metal or wood you have to use an adapter, then another drill bit. but if you got a cordless one too, then you can use that for wood or metal. I think all cordless drills comes with a keyless chuck so its easy to switch bits too.
another advice is you can rent and see before you actually buy the tool. just rent both drills and use em for a while and see the difference and see for yourself if paying more is better. In my case I own couple of normal drills and a corded hammer drill. When I need to drill a lot of holes I just rent a SDS drill. For now I don't have that many use cases to own one.
Great video. Anyway, I am interested building a pergola like the one on your video. Where did you purchase it? Thanks
The customer purchased it from Costco
I'm a DIY person and I noticed that my cordless and good drill bits just better than I remember vs 15 years ago. I think it has something to do with cordless being stronger and modern drill bits a lot better than back in the day. still, I prefer the hammer mode as without it the job is slower and a cheap drill bit becomes too hot or dull.
Makes sense
Can you share where did you get your pergola?
Just about to install the same pergola. Do you remember which drill bit you used? Also would you recommend using a tapcon kind of screw instead of an expanding anchor. I have read lots of people had issue getting the provided anchor to grip in the hole. Thanks in advance
I don’t remember. I believe it was 9/16. Also, just don’t over-tighten or use too big of a drill bit.
If using a regular drill for using it on concrete brick what setting should I have on ?
what settings etc?
What drill bit material used - cobalt? - for drilling through brick and concrete. How do I make I nice circular indention that will fit the square part of these bolts just under the head of the bolts? My biggest drill bit won’t so it. Is there a special type of drill bit for this application?
Can you do a demo drilling into a concrete wall, at a height of, say, 2 meters? For, say, attaching curtains rails?
I drilled 4 holes to mount an air compressor with a regular drill , one didn't line up when I was done , a regular drill will walk a little when it hits a stone in the comcrete
Yes all drills will walk on concrete, so you have to be careful and guide it back to center.
Thank you!!! Can you please teach a women how to handle DIY projects without a handyman? I would like to learn a basic skills to exersize for home projects, for example, (shelves installations, building boxes for gardening, patch a holes in the entrance with concrete, etc). Which tools are best to use and know how!! Thanks a lot. Lovely channel!!! ❤😊
❤️
Any recommendations on speed when using a regular cordless drill, and should I worry about the drill bit getting too hot?
I don’t worry about either.
Great video. But for large jobs and when in astm certified concrete in commercial building a regular drill would take very very long.
It can
I remove the nut and sleeve from the anchor ,and check that the hole is deep enough.
Every time i forgo that step , I regret it!
I thought I knew how to drill into concrete until one day I was drilling into something not even the hammer drill would do any good on so I bought a rotary hammer drill and omg it was like a hot knife through butter. In fact, I had to hold it back a bit.
Oh wow. Was it older concrete?
@@StayHandy it was the floor of a house about 30 to 40 years old.
is a rotary hammer drill different than hammer drill? looking to buy something to drill easily into concrete/cement. thanks
@@SlackersIndustry yes, they are two different things. I've found that the rotary hammer drill can be too fast sometimes and therefore go a bit out of control on some softer concrete and go too deep too fast if I don't hold it back. And I don't use it on brickwork. Mine is a Ryobi 1500watt but you can get smaller and bigger. Good luck with your project.
Try a pneumatic drill! It’s even better than rotary hammer
Use a bigger battery also helps
If you want to drill into concrete effortlessly. Get a Bosch Bulldog. You can find a brand new one for $145 if you look around. It will last you for years to come and has many uses. It is a rotary hammer so you can drill, drill and hammer or just hammer. Hammer only allows you to bust out stucco or concrete. It's like a mini jackhammer. You can use it to remove tile. It uses SDS bits so they lock in and don't fall out. You can use an adapter that will allow you to use regular drill bits if need be.
Agreed, I have a Bosch hammer drill and use the special locking bits. It's the ONLY answer for making holes in precast concrete panels which are the preferred format for building in Europe. The Bosch is the only machine which can zap into this material and I would have been lost without it for every serious installation when I moved here in Vienna six years ago.
I have a good idea - use an SDS drill and drill the hole much quicker, smoother, quieter and a lot less wear on the drill and bits.
I have DeWalt DCD796 hammer drill and I am struggling to to drill into the ceiling of my apartment which is made of concrete/cement. Any Tips?
what about impact drills?
Does it work in black top?
do you think this is also doable with an 18 or 14 volt drill?
It really does depend entirely on the frequency, size, and type of holes you're drilling into what type of masonry that seals the deal for what tool you actually need.
If you're the casual handyman who, on occasion, needs to drill a half inch hole into concrete, brick, mortar, cinder block, etc, the average rotary hammer with a solid masonry bit will work just fine. I wouldn't even blink twice telling someone to who needed to drill two holes for a concrete anchor into a brick to hang a gas cylinder bracket to use a rotary drill, even a cordless one.
If you do any sort of masonry drilling with regularity, of diameters larger than 1/2" into reinforced concrete, bricks, cinder blocks filled with cement, don't waste a second trying to use a regular rotary drill. *Find and buy the largest rotary hammer drill you can, preferably with an SDS or SDS Max chuck with at least 10 amps and 5+ foot pounds of energy and quality SDS bits that is CORDED*
You'll be legitimately shocked how quickly you'll pulverize all the above listed materials. Anyone who has large bore holes to drill on a weekly basis will attest to this. If you worked construction for any length of time and how to augur through masonry, you'd be either let go or laughed off the jobsite using a rotary drill, pressing with all your might trying to get through a single brick while the professional three walls down is slightly leaning into the wall with his rotary hammer drill bulldozing through with ease.
I've actually seen (and done in my amateur days) someone burn through two whole batteries on a cordless drill trying to drill into a cinder block nearly breaking their wrist through the effort. I walked up with the Bosch Bulldog Extreme with the notorious Bosch masonry bits and punched the desired hole length through in, no joke, 30 seconds. He looked at me, then down at his drill, and enough was said...which wasn't anything. In my opinion, Bosch and Makita make the best rotary hammer drills on the market with Bosch making the best SDS and SDS Max bits for said drills. They humiliate and brutalize masonry like it's an annoyance they're in thew way of the tunneling bit. Well worth the money.
You didn't mention any settings on the cordless drill itself.. would have been nice :)
Great video question how do you drill a 3” hole in concrete that’s 7” thick wall
There are special hole saw drill bits for concrete.
I needed to make 3" for ac lines and I had to make many 1/2 holes around the 3" circle. It took me an hour. I couldn't afford $75 for 3" hole saw.
I just drilled a hole in old concrete with a 3/16" x5 " bit .. for a 1/4" x 2 1/2" tapcon. for some reason that tapcon doesn't want to go all the way into the hole. Maybe i pushed too hard on the drill and it slightly warped the bit while drilling? would that cause issue with the tapcon going in? I like your tip on using the drill w/ bit and vacuum to clean . I did clean out the hole but used a little brush and canned air. any ideas on what went wrong and why the screw doesn't want to tighten down into the concrete? thank you
Most likely you need to drill deeper. Drill at least .25 inches deeper than you need then clean out the dust thoroughly. Go deeper if it's not an issue just to be safe.
Sometimes, broken rock debris jammed in the bottom of a hole that won't blow out can be a problem. That's where the drill combined with a vacuum can help. Probe the hole with a rod that's small enough to fit loosely to find out.
I have drilled concrete with a regular drill and masonry bit and it's not fun. What takes minutes can be done in seconds with a hammer drill. Worth the investment.
Thanks for your thoughts.
Very beginner question….What setting was used for the cordless power drill? (1v2 and 1-12)
Definitely gear 2 not 1, the latter is for screwing. For the 1-12 if this is your speed setting it's typ. somewhere in between but you have to try. The optimal speed depends on the drill bit and concrete strength. In any case don't overheat the drill bit. Have more and rotate through if it's a big job. Note that 1-12 could also be your max torque setting, then it's the max 12.
Is the cordless drill put into hammer action or is it set to drilling mode ?
