Thanks for putting this together. Excellent information and helpful in my work.
This was helpful, thank you. I need to drill a 4” hole 🕳 in a cinderblock wall to facilitate a dryer vent. I have no idea if the blocks are filled with solid concrete and rebar or what. I was looking for answers on TH-cam and this video has answered most of my questions. Buy a diamond coring bit and it seems like I won’t need any other tool purchases in order to make this happen, regardless of what I encounter inside the wall. Placing an order tomorrow.
Thank you so much!... This cleared so many questions, answers to which I was always looking for. Great content 👍
Glad you dug it! Thanks for taking the time to check us out, and please feel free to reach out if there is anything more we can help with!!
Amazing information! I'm gonna spend my money ey with you guys. I'm from MA
Thanks for the information. I have a small number of holes to drill through reinforced concrete and I'm just looking into the approach to take.
@Ohio Power Tool. Thanks Nick for the quick video on the coring options. Now I know who to call when I need help.
Hope you and your family stay safe and well.
Good info...thanks Nick
Variable speed grinder works well too . They gave 5/8 inch arbor for the bit to screw onto if doing small job like tile…
Great, all the necessary information and no chit chat!
Thank you for watching!!
I've searched for video's on core drilling until my eye's crossed and not one time did it suggest your channel unfortunately. I'll be in contact soon. I use a SDS plus to core holes for up to 2" conduit almost daily. Usually 1 per job site. The local tool stores keep pushing to upgrade to SDSmax and tell me there are no SDS plus core bits that big because the drills can't drill them. Well they will. My 1st drill (Dewalt) lasted 5 yrs before it stopped. Use 5A 20V XR batts and only recently had to replace 2 because they won't keep a good connection.
I was ready to buy a core drill, but thanks guys, now I know I don’t really need it!
That makes these videos all worth while - Very glad it helped!
Great no non-sense video. Fast and straight to the point. I didn't even know this product existed. Do you sell it in Canada?
Thanks so much! Unfortunately we only ship within the US but you should be able to purchase Diamond Products core bits in Canada through other sources
Gostei! Inscrito!
Tirou minha dúvida.
Obrigado por assistir e seguir! (Thank you for watching and following!)
I need to drill about a 100- 5/8" or 3/4" holes in an un-grouted masonry wall for ledger anchor placement before grouting. Can you recommend the correct type of bit and drill mode?
This video kept me from making a goof on my first large bore through brick and block! I was about to use my SDS max, which would have made a mess.
Very helpful
Glad we could be of assistance!
Can't you use a Hilti 263359 and chuck 60208 to disable the hammering function of an SDS max? It makes everything longer but you've got a heavy duty unit.
I learned the lesson hard way. I wish I watched this before I purchase. I bought an SDS max to do some core drilling with diamond bits, only to know that my SDS max (most SDS max drills) doesn't have a "drill only" function. I was thinking more power is always better.
Can't fault you for thinking that way! If you need any help getting the job done, let us know and we'll get you set up. Thanks for watching!
I was planning on getting an sds max as on top om my plus bit I didnt know most sds max drills didnt have a drill only function as well. Thanks for the heads up.

They saying dont use hammer drilling with diamond for just precausions specially with noobs thats a common sense
Hi I am going to do ALOT of curbside core drilling 3.5 size for 3 in drains what drill an bit do you recommend for this? Thank you
Wow ..Thanks a lot
I want to core drill 4 1/2" hole about 6" deep into natural rock, but I only have a 7amp angle grinder. The rock size will be 16" cu. And ether rundle rock or river rock. Can it be done with a diamond cup??
Great video. What are the SDS Max machines out there with drill only mode?
Check out the DeWalt 60v SDS-Max like this one but there are others www.ohiopowertool.com/brands/dewalt-power-tools/dewalt-cordless-tools/dewalt-cordless-rotary-hammer-drills/dewalt-dch481b
Can I use a sds Milwaukee 4” hole bit with a 18V battery hand drill?
Nick I have the m18 fuel mid torque impact wrench, not sure if that would work with one of those bits
Unfortunately not, these are either threaded or SDS. If you need a hammer or core drill though, we've got some 😉
Gonna use Milwaukee 1 1/8 sds + for a 3" and 5" core. First time drilling a core and probably won't do another one for a while. want to get the sds + adapter for a diamond bit. Any recommendations for which bit?
Sure, pretty pricey for a one time use, but this should be what you need:

Great video - thank you very much. Can I get a 7/16 quick change shank coring adaptor for a normal drill like the DCD130 dewalt mixer/drill or the big DCD470 right angle joist drill? I saw the threads in the back of the diamond core bits at the local shop and wondered what fitted that, and now I know, but hopefully there are adaptors made to suit normal 1/2" chucks.
We don't sell a 7/16 quick change adapter, since dry core bits can attached to grinders or hammer drills can't see why this wouldn't work if you found the right adapter (assuming from a reputable manufacturer who tested and confirmed this worked) we just don't sell one currently.
@@OhioPowerTool turns out the local shop did have them, just not in stock, they also had a kit of different sizes which included SDS and hex adaptors, which is what I ended up with, so all set for diamond holes in concrete in future for most common sizes.
What do you recommend for basalt rock? Plan on putting posts right in, thoughts?
Oof, basalt's a tricky one. It's a very hard and dense rock, and if you aren't careful, you could end up going through four or five bits before you even make a dent in the thing. You'll want to look for something with a decent diamond count, the tougher the better, though there are some who say using a pilot pin and reaming out bits of basalt at a time is the way to go. It'd take a bit longer than straight drilling, but you'd potentially be saving an incredible amount of frustration and money going the reaming way, at least according to those that prefer that method. Either way, you'll want something that has the diamond count to break through even the toughest of materials. Great question!
What do you recommend for cutting a nice clean/professional looking hole through stucco? Thx!
We would recommend a wet diamond core drill bit, they are the most affordable and are suitable for drilling small holes in stucco. It is recommended to use a low speed setting on your drill when drilling into stucco to avoid damaging the surface. Apply light pressure and allow the drill bit to do the work. We hope this helps!
@@OhioPowerTool I had already ordered a carbide one and its coming today in mail. Still ok?
Why do you say diamond doesn't pound the concrete but carbide does? Aren't they both supposed to be used only on drill/rotate mode?
Im a DIY homeowner. I dont core often and only have a few times. I dont have the money to spend on a fancy drill for coring or a hammer drill. So what i plan on doing is drilling out holes around my core and tapping out the core with a hammer. I dont want to spend 100$ on a bit I'll use once. It's for a dryer vent.
That's very fair! Just be sure that you're taking your time with it and start small! It's much easier to remove more material than it is to add it back on if the hole ends up too large!
@@OhioPowerTool thank you for the helpful tips. I appreciate it. I know you guys work long and hard to gain your knowledge and I appreciate you giving me free knowledge. It’s also a hell of a lot easier to take more often than it is to add on lol.
I have the d25481k. I have been asked to put a 4" ballard in asphalt.
Do I have this option with this tool? If so Will bits gum up and such?
Down the road I'm going to have to put a dryer vent or 2 through a pretty thick brick wall as well. If this tool is for the job.
If you have what I might be able to use post links. I have nothing in the way of the centering bit set up for this machine either... just bits for chippiing so far
Thanks
D2581k is just a Dewalt chipping hammer right? If it doesn’t have drill only mode probably not going to work. Asphalt is very soft and abrasive not hard to drill through but yes gum up the works so to speak. Better with a diamond drill bit not a carbide bit. For cinder blocks either should work but again diamonds will give you a cleaner hole without chance of blowout.
@@OhioPowerTool
That project (like all of them) morphed into something way bigger so its off the table but, the one I have has a drill only mode. Its not here in front of me but, theres 3 switch settings marked with hammer logo, a drill logo and a combo of hammer and drill logo around the knob if im recalling correctly.
I need to mount the bases for uprights to a handrail. 12 5/16” holes. After 30 minutes and ruination of 2 carbide tipped bits with the result of 1 hole, 1/4” depth. Got to be an inexpensive way, doesn’t there?
What kind of drill are you using right now? We would recommend a hammer drill if you aren't already!
I'm a home owner. What would you recommend for drilling a hole in brick for a hose bibb.
It depends on the characteristics of the brick, for standard brick a good quality carbide-tipped bit would work fine! Although if you encounter exceptionally hard or dense bricks you may need a diamond core bit. It may be best to just get the diamond core bit, just in case. But that is totally up to you!
Best core drill brand under 1000£, looking to get into the bussines as sole trader at first and trying to determine the best brand that will do its job! No chinesium
WEKA drills are best typically, here in US those are from Diamond Products but I think they import from Europe so might start there.
Try Cardi. Wide range and cheaper than Weka or Hilti or Baier or Milwaukee. For beginning also good: AGP or Eibenstock.
Which one would you recommend for my sds max cord drill?
Most people using SDS-Max drills use carbide core bits because they are used in hammer drill mode which won't work with diamond core bits. Hopefully this video helps understand the difference of the 2 types and when you want to use a diamond bit instead. Also how those can work with SDS-Plus and many SDS-MAX (if they have a drill only mode) hammer drills.
I need to drill a 50m (2 inch) hole through an old stone wall about 18 inches thick. I can buy a masonry drill bit of that length but that won't be 50mm wide.
Drill a standard 2” core bit with a 12” extension then break off core after 10” or so inches and you’ll be able to go all the way.
what type of drill do I use with the diamond?
Typically you'll want to use a core drill, but with the new Diteq adapters you're able to use them with an SDS Plus or Max rotary hammer as long as it has a rotate only mode. The one we used in this video is the Metabo 600765620!
We want to drill into a garage floor to install plumbing for a toilet. It will be next to an outside wall so we only need to go a few inches. How will this system work. We have been quote $3k to do this by someone else. Thank you for any suggestions
There is a lot that goes into installing plumbing into an existing concrete slab. While we sell a lot of tools to help trained professionals do this work this is not a DIY project or something we’d give advice on. Raised some questions for us here in Ohio where it freezes only going a few inches and going outside. A $3k quote might be very reasonable depending on what all they plan to do.
what hole saw , i can use in a stucco soffit i need a 4" hole saw for lights
If you are trying to avoid chipping stucco a dry diamond bit on a low RPM grinder will be the best bet. Hammer drill with carbide bit will pound and break the stucco...
Which type should use water Cooling, and most important, hammer or not too hammer ????
Carbide Core Bits hammer into the concrete to make a hole, this is compared to Diamond Core Bits that are grinding into the concrete instead, which saves you time! Carbide Core Bits require a coolant to prevent burning and overheating, where Diamond Core Bits do not require a coolant as they will not overheat due to their way they are manufactured and their heat resistance.
Tried drilling 4" hole in brick wall. Bought new carbide bit. After 10 minutes only got 1/8 " deep at most. Cheap bit?? ($22). Are there different types of carbide. Ad stated multi purpose from wood to brick. Should drill be set on drill or hammer.
There are definitely different types of carbide bits, ones promoting wood typically don’t do well in brick or concrete. The ones that advertise masonry and concrete will get you right through brick unfortunately cost way more than $22 for 4” bit.
@@OhioPowerTool Thanks so much for getting back to me so quickly. Your response clears up a lot for me. Your company is the best!!
What is the best thing to use if you’ve got like 42 holes to core?
It will depend on the material you're coring, but a diamond core drill with core bit may be the better alternative for that many holes.
Am i meant to use hammer mode on my sds when using carbide core bit?
You will want to use rotary only, hammering can and usually will break the carbide teeth.
@@OhioPowerTool Got lucky today then! I was using hammer for a little while but doesn't look like the teeth got damaged. Won't be doing that again!
Handheld core drill has slip clutch adjusted/designed to specified diameters of core drill. E.g. with Husqvarna DM220 you can drill from hand up to 80mm (3") according specifications. In reality and regarding material it is managable up to 150mm (6"). So in some cases it is better to rent the machine and core bit or rent the machine and buy own core bits.
Thank you for your input. We’d agree different materials are going to be softer and easier to drill but you never know when you might hit rebar or some other harder rock that could really bind up a drill. Most handheld core drills will say 3” handheld or 6” mounted in a stand. Certainly the drill can handle it but not the user.
Actually, I honestly believe it does matter what the back side of a hole looks like because that changes the structural integrity. The shape of the arch that's created can make a big difference on the amount of weight the structure can handle around that hole. So guess I don't agree with that ultimately it doesn't matter myself. Maybe most people only think about the looks more than anything but that doesn't change the facts any. Perfect arches hold a lot of weight
Have to cut a hole for a 4 by 4 in my concrete sidewalk help
Hopefully this video was helpful, lots of options for drills, core drill or sds-max. Typically 4x4” measures 3.5”x3.5” so a 4” core bit will give a little room to wiggle. (Obviously larger hole needed if trying to support with new concrete) Diamond core with water would be the best option but carbide hammer core bit would work here as well assuming concrete is in good shape and not on edge of sidewalk (as more likely to cause crack). Always happy to let you know how tools work but can’t give any structural or building advice.
Nick Do You Have A Adapter From Sds Plus To 13mm
Unfortunately, we do not have an adapter of that size. What are you looking to do?
@@OhioPowerTool I Meant A Chuck Adapter From Sds To Normal Drilling
www.ohiopowertool.com/p-23844-diteq-sds-plus-to-58-11m-hammer-drill-adapter-to-core-bits-151670.aspx this is a bit bigger than what you're looking for, but its all I really have at the moment
@@OhioPowerTool No Its A Keyed Chuck With A Sds Plus Shank
ah, got ya. Here is SDS-Plus to Keyless chuck - www.ohiopowertool.com/p-6433-bosch-sds-plus-to-keyless-12-chuck-adaptor-ha3jaw.aspx
Diamond has always been better for me personally. cleanest coring ever.
It’s typically the better way to go, definitely cleaner holes but we wanted to give the different options.
So if I wanted to to make a 6 inch wide by 6 inch deep core into reinforced concrete… a hammer drill with dry diamond bit in normal drilling mods will do the trick?
Tools for amateurs!!
I work every day with professional tools, ( weka - Husqvarna- ) are the best and I drill on real hard concrete whit water and dry..
Agreed ,I'm a concrete cutter I would never even contemplate using a hammer drill thats nuts it would take forever not mention hammer the drill or burn it out, ill stick to my tyrolit core drill I think😳
@@justinn446 Bosch hammer drill and everyone else applauds.

How much
Hey Felix! That depends on what you're looking for; we've got diamond core bits as low as $70 or as high as $300!
Everybody likes a nice, clean hole!!!
No doubt!
Seems like a lot of the older men like all natural holes 🤮
If I have a carbide bit, couldn't i just drill a pilot hole through the block wall, drill both sides of the block wall and meet in the middle? To ovoid blow-out i mean.
That would certainly be a better way to do it if you can get to both sides.
Never seen a sds max Roto hammer with a rotate only mode… any ideas? Google search is useless.
Several dewalt models do for sure but yes not common across board like with sds-plus.
