Couple of points from an ex diamond driller with 20 years under my belt. No1. No dust mask seen. Brick, concrete and blocks contain silica. This is rapidly become the next asbestos replacement killer. Not something you want in your lungs. No2. Use a dust vac or a water suppression kit. Failing that, wet the wall down with water before you start and regularly throughout the drilling process. Rinsing the dust out will reduce the drilling time. No3. Flushing with water will cool the diamond segments which will prevent them from being debraised from the barrel. No4. Segments that become detached whilst drilling, must be removed from the cutting face. If left in they will fetch the remaining segments off rendering the tool useless. Snapping the core out with a screwdriver will aid this. No5. Slow drilling can be sped up by hitting the tip of the segments to open up the diamonds again. Several good belts with a large file on each segment head should be enough. No6. Should the core get stuck in the barrel. Turn the drill so that the core can drop out. Gently tap the outside of the core barrel all the way around with a spanner. Keep rotating the barrel and the core will drop out eventually. Hitting the barrel to hard will resort in a distorted barrel and lead to further binding whilst drilling. No7. Once the core is through, rinse the brickwork down with clean water - this will prevent staining. No8. Allow wet slurry time to dry out. Trying to brush it up will only spread the mess further. It will brush up once dry. No9. Whilst working at height do not attempt freehand drilling. Hire a drilling rig which you bolt to the wall via a plastic plug and locking dowl pin - it’s much safer than being thrown off a ladder at height - trust me on that!…….

I really enjoyed the way you explained it. Smart and clean. Only for safety put on a mask too beside the safety glasses. For protecting of all that dust entering to your lungs. If you do this on daily basis it can lead to nasty lung diseases.

[@stephenspiceley3082]

One little tip that I use to ensure you don't get plaster blow out on the inside is to use the core bit on the inside to just cut through that first half inch or so of plaster. Then move to the outside to cut the hole. The pilot hole will ensure that the two cuts line up perfectly, and as you have already cut through the plaster on the inside you don't get it blowing out as the core goes through. Sure, it does make a little dust on the inside but worth it to keep the plaster in one piece. 👍🏼

For pros, Makita do a dust extraction accessory for their diamond core drills - very expensive and heavy duty. As heavy duty DiYer, I do what you do

[@Nine-Signs]

@@cuebj Potential cheaper solution? Henry + bag. Henry likes to eat all things, and rolls down stairs well, and are still pretty cheap. Mines 25yrs old and for the last 7 has been sucking up everything from masses of brick dust to lose cold ashes around the fire. Remarkable machines, especially the older ones.

[@kchaney56]

Brilliant pilot hole advice.

[@johnashton4086]

I can tell you from experience that the core bit / drive shaft you are using will bind together after heavy use. It is then virtually impossible to separate the shaft from the bit and that means you cannot change bits thereafter. Before use I would recommend making and breaking the shaft/bit joint and also using copper grease or similar to make subsequent release of the joint more likely. I was drilling foundation wall that consisted of heavy-duty concrete blocks laid on their sides. The second point I would make is that the stub shaft being used will not get you through such long traverses. Eastablish whether you need a shaft extension before committing to task as separate purchase of long shaft is expensive. If these extensions binds and won’t release you will have an even greater problem to solve. I eventually resorted to stitch drilling after first creating the first short penetration using diamond core. That worked well and was faster but not a neat finish on the exit side of the hole.

Always use the correct core drill with a clutch so save broken arms and wrists,i would not recommend use a standard drill for this type of job !

Exactly. The clue is in the name. Core drill for a core bit. SDS could land you a trip to A&E

I uses an SDS to core drill all the time, it has a clutch and has never kicked back at me.

[@sydsnott5042]

Ok that's acceptable what you've stated But I did just that job some years back with a standard hammer drill. Yes I got got some slight kickback but I got the job done without any broken bones or bruises. Yes I took my time.

Young guy I was working with drilled a core hole using a standard SDS. Drill kicked back and he tore his rotator cuff in his shoulder. A month off work and it’s at least 5 years ago now and never been right since 😖. Core drill for a core drill bit every time.

Do you have an idea on how to drill onto uneven surfaces? For example: rocks on the beach area? The goal is to build and plant a metal post onto it.

[@NeilFirbank-en1yd]

If you are drilling through something a bit tougher and maybe using a long extension, try drilling 4 holes at the top, bottom, left and right outer parts of the hole you are trying to cut. This makes the core bit easier to drill through the wall as it hasn’t got as much friction due to the holes. I’ve done this many times, it makes it a lot quicker and easier particularly if you are in a tight spot. Try it out.

[@samirguesmia4378]

Great video! How would you go about enlarging an existing hole to fit a cooker hood that needs a bigger hole?

[@cuebj]

Corbett? Need Barker, too. Good tips, which we used a few years ago. For the more casual DiYer, this is a case where hiring the gear makes sense as you might just do it once. The Erbauer kit is pretty good, even for pro tradespeople who don't do this all the time. If it's a tiled wall, use a tile grinder to remove tiles with about 5mm extra radius and cut hole a few inches deep from the tile side first, then cut from the outside. The pilot hole ensures the two holes meet up. You might have to hack insulation from the cavity as the bit gets clogged

[@TheDIYGuy1]

👍 cheers and thanks for sharing

[@Surbitron9000]

Excellent video. Thank you.

[@elpresidente8730]

I have the same set of Erbauer drills. It is a bargain buy. If you purchase the 3 core drills and the mandrels separately it would cost double what you pay for this and you wouldn't even get the case. I have a 117 core to drill tomorrow in the loft. fortunately it's a double skin of breeze block with render on the out side so it won't take long. I drill the outside render first then drill the last inch from the inside to avoid blowout.

[@assili_abdellah]

Thank soo much freind, i appreciate a lot your advices, i lear lot of things from you , thank again , good luck for futur videos

[@JamesSmith-gk8sz]

Secondary pro tip if dust/debris mitigation is a concern. Bosch (and other tools brands) makes a suction cup attachment to the shop vac that, when the vacuum is activated, suctions it to the wall. You put your drill or core but through the center of the bristle attachment and all dust and debris get sucked out as you go. Saves a huge mess and minutes of clean up afterwards. This also saves you from wearing a respirator, which you should be for any masonry drilling application. Silica and mortar dust is incredibly harmful to human lungs.

[@TheDIYGuy1]

👍

[@MortenMadsen1982]

Isn't it a better idea to drill at a very slight downward angle, so water will drain to the outside?

[@h.google]

Awesome job 👍🏼

[@tomsanders8714]

Great video. One thing I'd point out in my case - even if it means some vertical ducting inside stay well clear of the DPC. My house sits on a plinth of some sort and if you hit that your hole stops there. Got lucky, but it was close!

[@Trucker-Belly]

DPC? Democratic Political Cheat?

[@cuebj]

Good point. I have exactly that: rectangular duct between wall and dryer, rectangular to round connector to duct in wall. Unexpected benefit is it's more flexible when I've changed position and brand of dryer - just shorten or lengthen the flat duct and change angle from dryer vent to wall vent

[@glennpowell3444]

Believe it not if a powerfull drill bit stops suddenly on a job like this depending how you are holding the drill it can snap a wrist or finger.I know.Once youve broken the cavity into thermalite blockwork no problem but if you hit brickwork assuming your going from inside just go real gentle as it starts to bite the brick.If you put too much on it the bit will stop and the drill power rotate allarmingly around it with alot of torque particularly a corded one.

[@TheDIYGuy1]

Yeah your right!

[@MrDigga53]

And thats another reason you actually use that side handle and not bin it like many do !

[@chowpey]

not sure if mentioned here, you should always have the angle of the hole pointing outwards even slightly so that any water drains out and not in!

[@thebrooklyngardenclub225]

Nice work, thankyou ..well done.

[@AccountantDoesDIY]

Great video. I’m a bit wary of my SDS these days after almost snapping my wrist recently. I have the Titan beast from Screwfix. Was drilling some 18mm holes into a concrete pad for some rebar to go up the middle of brick piers I was DIYing. The drill bit suddenly got stuck about 250mm in and almost ripped my arm off. Darn scarey. Then spent about 40mins trying to get the bit out again :-(

[@AccountantDoesDIY]

I should add - I know I should have set the rebar in the concrete when I actually laid the foundation pad but I’m only a novice and only realised after the fact that rebar up the middle was needed…

[@TheDIYGuy1]

It’s certainly something to be aware of. Thanks for sharing

[@neilballam8701]

I've got that drill, an absolute monster. Ate thru my 1920's red brick to do this job. Took a lot longer than 10min tho. 😂

[@paolocoletti3424]

You would normally notice when the bit was starting to jamb. Never continue drilling as at some point it could bind and give you a serious injury. Keep the speed high and pull out to clear the debris at regular intervals. (Although on vertically drills this is difficult) Don't ever just try and push through a binding bit, It's blooming lethal! Stay safe

[@MrDigga53]

Thats why they provide a side bar handle that lots of people don't use! and a core bit should be driven by a specific drill unit that is designed for that purpose.

[@NeoFreshair]

If you go up on the ladder, make sure someone holding the ladder for you, and even changing turns! You can get tired quickly higher on the ground holding heavy drill and it will feel more heavier!

[@IAAITKEN]

Dust aside - if kick back is most likely going into the internal wall from cavity. Would it not make more sense at this point to drill inside outwards? Some does but avoids kickback and also blow out risk?

[@wassupjg]

Why remove the drill bit after making the first round cut into the brick? Wouldn't the bit use the pilot hole to keep the cutter straight?

[@kirembweabdulkareem3294]

I've been prevaricating on this one for my cooker hood for months, I'm sure I'll brave up enough to do it eventually - my complexity is timber framed house so i got moisture barrier to deal with also; though I also have only one layer of brick to deal with so swings and roundabouts.

[@cuebj]

Hole saw or pad saw for the timber and plasterboard. The single thickness brick could be done with lots of holes using 6mm or 8mm SDS bit; then tap with small cold chisel. If you do hire or borrow diamond core gear, practice on a paving slab or block. Get very comfortable and solid in your stance for holding the tool and moving it through a position that mimics the hole you want to make - can you hold it without dropping from your line?

[@edwinbruckner4752]

I did mine on a ever so slight angle, so that in case of some heavy rain, water has zero chance of getting in. As water does not flow upwards..

I got a Makita diamond core drill instead, not SDS. Wow! So much better engineered than the big yellow. The Erbauer bit kit is excellent (see my other comment)

The day of judgment is decisive and displays to all the seal of truth. Just as now a father does not send his son, or a son his father, or a master his servant, or a friend his dearest friend, to be ill or sleep or eat or be healed in his stead, 105 so no one shall ever pray for another on that day, neither shall any one lay a burden on another; for then every one shall bear his own righteousness and unrighteousness." 2 Esdras 2:31 ;,,,,,,,

[@jamesbruce3105]

Great video that gives a lot of useful tips. However, it's a bit dodgy to advocate using an SDS drill for such a large core bit. A diamond core drill is the appropriate tool for the job to avoid snapped wrists or injured fingers. Also, the 8mm pilot drill bit supplied isn't an SDS bit it's a mandril bit.

[@TheDIYGuy1]

Thanks. I value your opinion however this video is for the DIYer and they aren’t likely to own a core drill for the odd hole but they are likely to own an SDS. Whilst a dedicated core drill is better, the use of an SDS is very safe if it has a clutch and is used following the tips in this video. 99% of tradesmen I’ve worked with over the years use an SDS for this job with no issue.

[@jamesbruce3105]

@@TheDIYGuy1 That's odd because I've never seen a legitimate professional use an SDS for a 4" core bit. They value their earning potential too much to skimp on a few hundred quid for a diamond core drill versus broken bones and lost income. I take your point that the average DIYer would not have a core drill - but at the same time, I don't think the lack of the appropriate tool should be the justification for advising using one that's not designed for the job at hand. Most SDS drills either don't have a clutch or if they do have one it's not designed to work with this size of core drill effectively and protect against injury.

[@the_f0]

is your drill machine rated for 117mm drill ???????

[@adrianopereira7379]

qual a marca e modelo por favor

[@matthewwhitley]

I need to do an extractor hood with a 150mm out on it. But I don't really want to buy a 152mm bit as I have a set of smaller ones. Am I ok to use the 117mm bit and step the ducting down?

[@MrDigga53]

You could.. but you will reduce the effect of the extractor slightly. Hire the core from your local shop would be my advice.
