I core drilled my double skin conservatory wall for some insulated Air con pipes & condensate drain. Worked fine. Must have softer bricks than you have. Keep up the good work & looking forward to part 4.
Nice work Andy. I've burned out some drills in my time core drilling old bricks so agree on hitting them out if you can get away with it.
Yup! Seen a lot of drills destroyed this way. 😂
That's what the cheapy screwfix SDS drills used to be for - it used to be cheaper to buy one of them and burn it out after a few jobs than it was to hire a beefy SDS. Not so much anymore :(
Hi again Andy. Great job and thank you for continuing to take me on your journey 🌞
No worries Ray! 😎
Great work yet again Andy.
Cheers Ian!
Thank you, love the videos!
No worries!
Good as always. Years ago I did hire a core drill with diamond bit for my old 1920s solid wall. Just sat on my bum with the big old drill, nice and slow. Very satisfying. Just took ages getting the cut bricks out te deep core bit lol. Nice to see another way to tackle the task.
Cheers! 👍
Andy I’ve got the same Erbauer core drill kit, I use it regular fitting kitchens and use my cordless SDS drill with it, cuts through brick easily enough mate, not sure if you’ve tried
Brilliant as always Lad.. Top job.
Cheers Scott!
Great video! Lots of detail on which tools to use and why etc. Would be great to see a video on how your organise and store your tools. Me and my partner are novice DIYers and finding it so difficult to keep track of all the tools weve bought!
Coming soon(ish!) 👍😁
Thanks for the video Andy, very informative.👍👍
No worries Terry!
Core blimey that’s tough brickwork 🧱😏. Me and Al took out a door opening through a 9inch wall. Disc cutter through one skin then Stitch drilled second skin … we looked like we had been tangoed 🟧😷😂🧱😷
Honestly, those Hotspur bricks - like engineering bricks on steroids 💪. Even just the stitch drilling took forever. Yes, the dust is so much fun! 😂👍
Great progress
Cheers Tahir!
19:11 Well that's a first for me! Never seen anyone vacuuming their outsides walls 😄
😂😂
Tidy is as tidy does Andy !!
Had to cut a 117mm hole to reposition extractor fan. Tested my old DeWalt big SDS drill with dry diamond core bit in a paving block. Got very hot very quick. It needs a service but good reason to get a diamond core drill. DeWalt corded standards have plummeted. Got Makita. Glorious clean smooth cut.
Thing is, I got lucky. I was in a layer of modern 2003 red brick. Any lower, 100-year old London sewer brick in lime mortar (very hard and luable to shatter); higher, is soft cement block. I have used diamond core in sewer brick below a dpc and it went ok. But risk of movement and ruining the bathroom tiling was too great for comfort
Losing the centre bit down a cavity is exactly what happened me - gone forever.
Nightmare! Easily done!
Nicest bloke on RUclips. How someone hasn’t picked you up for TV I’m not sure. Much love from Houghton-Le-Spring.
Aw thanks! I've turned down the odd request for TV. Not my bag. 😁
Great video Andy. Where did you get that little sink from, I'm after something similar...
Once again, you did it with the tols at hand... However, non-impact diamond cutter core drilling might well be more pleasant. You can even get dust extraction up to 160mm from many manufacturers....
Tried both methods many times. Removing bricks makes much less mess so better option if you're not dealing with facing bricks, IMHO. But each to their own! 👍
The Allen key is for a grub screw which holds the pilot drill 👍🏻
There's no grub screw. 👍
@@GosforthHandyman Depends on the size and brand. Smaller ones mostly don't have one.
Andy just check about the door opening inwards, as to building control fo wheelchair accessible. I know it’s not new build but deffo would check with your architect or building control officer.great video again mate 👍👍 looking forward to the soil stack shenanigans 🤣
Cheers bud! This was last year. 👍
good work ! well done
Cheers Mark!
👍👍👍Thank you.
No worries Pete!
Future reference, as the job I'm sure is done now, but you could have used a toilet pan connector with boss to take the waste from the sink, would have saved you the trouble of drilling the smaller hole.
Cheers! Building inspector said we'd need a durgo if we did that, whereas straight in to the stack we didn't need one... apparently. 👍
@@GosforthHandyman I should have guessed you'd have already explored that option 😄 I don't understand the advice your inspector has given you though. You must already be venting externally which will already be balancing the pressure so what benefit would you obtain by adding one, and why would routing into the pan connector (and avoiding adding a couple of feet of pipe) suddenly cause the need for one?
Great video !!! thank you !!!!!!!!!!!!
No worries!
I core drill through brick with a 36v SDS+ drill all the time. Old bricks are much harder so it takes ages, but it's possible.
Defo possible! Not with my little drill though. 👍
Love your content. I’m actually doing a downstairs toilet at the moment and just stumbled across this video. Out of interest did you consider a pocket door?
For you, at this point it must be all done; but I'm not looking forward to the opening of the soil pipe - and that's out here in viewer-land! BTW I've got an SDS Hammer/Drill, what's this with greasing the end of the bits?
Here's the silly bit. . . you go to all that trouble building a two-story ext + roof rebuild and then you go knocking the bricks out at the bottom - made me smile, thats all! Nice one Andy, keep up the great videos.
Yeah, that wasn't fun. Dribbled down my arm 😂.
@@GosforthHandyman Spoilers sweetie, spoilers. I wait for the video! 🤣
I'd recommend using the Makita HR2630 it has a better motor than the HR 2450 , I've used both on dozens of 4" core drilling .I do get that hundred year old bricks are the toughest but I've had more problems with damp bricks .
Not replacing my 2450 'til it literally dies - we've been through too much together! 😂
How often do you greese your sds bits👍🤩
As often as possible 😂
You could stitch drill the hole first then use the core to make a nice clean cut. It's much faster in hard materials and you should use a solid body core connected to your vac ideally so you don't throw tons of dust around.
It would just jam.
@@GosforthHandyman only if you have a lower powered drill. Anything with around 1200 or 1300+ watts of power will do the job.
Great job! is there a reason why the bottom toilet hole was much bigger than needed?
It's easier to remove whole bricks where possible and then just brick up around the pipe.
@@GosforthHandyman That makes sense, I wasn't sure if you just filled it with morter or some other product. You can tell i'm not a builder.
Ive had a few situtions in my time where the basin been right next to the toilet would have been fantastic
🤣
😂😂
Double exits, yuck.
i've never put grease on my sds, is that something old school?
Makita used to recommend it, maybe still do. I still have some of their grease. Other brands I've seen don't mention it I do need to get my DeWalt SDS drill serviced after many years extremely hard work
Do you have an outside tap? Would love to see how you instal one, one day! 🤞
I think PlumberParts has made a better vid than I could ever do! 😁👍
Probably miles too late, but a sliding or pocket door would be a neat solution to the space issue. Put a pocket one in my hall to my kitchen, so no accidental thumping anyone when opening it.
Cheers Jules! Couldn't really due to the fan and wiring / switches in the wall. 👍
I use a medium size SDS+ drill, so a size up from yours. That does work with a similar type of core bit 150mm trough old hard bricks.
Buying one of these core drill bits for around £40,- is the cheaper solution, these bits will do around 6 holes trough a double brick wall.
Hiring a core drill does only make sense when you have to do a multitude of holes, as the fixed starting rate for hire and wear is already quite hefty.
But for the same money as hiring you can have a professional doing the job for you
I just use mine in concrete blocks but yeah a beefier drill could do brick but they often crack as there's imperfections in the old bricks. 👍
How would you go about reselling those holes
Next time! 👍
Maybe a daft question - why didn’t you use a hole cutter rather than chopping out the bricks? Would’ve left the wall with greater intent and strength I think? [Edit - because you haven’t got a big enough drill to drive a core drill and you think the bricks are too tough!]
Yup - these bricks are unbelievably hard! 😂
They don’t seem as tough as the 40cm wall I am currently core drilling, it’s granite of all shapes and sizes
5:42 A 4'' grinder with a diamond blade is much easier and neater. The blades are cheap as chips as you would say.
Dust would be epic!
@@GosforthHandyman It's just to make a groove about 1-2'' deep. Need a fan and mask. Keep a window open. I've done it many times and as long as you don't cut for more than a couple minutes at a time, with ventilation you're good.
What about a folding door, so it can still open inwards?
No real point - opening outwards isn't a problem. 👍
👍
Storing away tools (core drill bits) without cleaning. Shocking. I'd never get to sleep.
Good advice on removing the centre bit Andy, that would seriously spoil your day, this is the equivalent of always remember to put the bath/basin plug in before undoing any small tap fittings !
Biggest issue with basin placement is stupid people using it as a grab handle and putting their whole weight on it, so yes, preferably keep it away from the bog !
I think I'm looking forward to the soil stack video, but perhaps I won't watch during breakfast ! 😉💩🤢
Yes, probably avoid during breakfast 😂👍
I recently did my first core hole - 165mm for a kitchen hood vent. I bought a "proper" core drill second-hand on eBay and it was knackered from the get-go, so sent it back for a refund. The scam-artist seller only refunded 50% (they lied and said I'd opened the internals - scum bags), so I had to get eBay to refund me the rest (!), which they did without hesitation...
Long story short - had to use an SDS+ Titan drill with safety clutch but not as tailored to core holes. And just had to be mega patient with it. By the end it was VERY hot and struggling with the clutch a bit... So hopefully it's not knackered (less than £100 from Screwfix a few years ago though, so fairplay).
I would highly recommend EVERYONE search for the Bosch core drilling safety guides here on RUclips - they teach the proper way to set the handle to minimise risk of wrist damage. I never knew the handles on drills should be used in a specific manner. But they should - and it might save you from injury. The Titan did catch a few times and it's pretty scary - but if you're holding the handle correctly you can take it in your stride no problem.
Hood with vent to the outside is f**King pimp too :-) absolutely love it. £218 from B&Q and it does fully auto venting (even calibrates to air conditions in kitchen on turn-on). Bloody brilliant bit of kit.
Nice one Jamie - it can be a real challenge!
Watched the Bosch video as you suggest. Great advice.
Hi Andy
Wrap some bare copper wire from a bit of 2.5mm t&e around the thread between the core bit and the drill adapter. Stops it binding when you take it apart. Great video, looking forward to the next update. 👍
Oh and I mostly use a cordless SDS with 5Ah batteries
Good tip!! Cheers!
Always prefer a clean hole! So many double entendres in this video I cannot keep up😂
I listened to a podcast about Canadian beaver wars today, hard to keep a straight face!
It gets worse... 😂
Imagine if the drill slipped and you hit the existing pipe 🙈
There’s nothing better than making big holes with a long stiff rod😂
Too right! 😂
Ah... the Gosforth Butcher is 'in da house'.😂
Have to say... you really did a number on that wall. All for saving a few quid on hiring a proper core dill 🙄... then leaving up to your better half to then tidy up after you. 🤭
Nothing to do with saving a few quid, this is a better method for hard bricks like this.
@@GosforthHandyman In that case I guess all the holes I've core drilled out in brick (not block) walls including engineering brick ones must have been a
figment of my imagination eh?
Either that or I've just got lucky over the years and in fact them brick walls were all actually made from secret English hard-cheese bricks. 🤣
Will now go off and give my coring drills a stern telling off for going through... Bricks!
If you place a nitrile washer so it sits on the shoulder of the chuck it will make removal easier in future projects. ruclips.net/video/Y4LsIISmVmI/видео.htmlsi=p3eW7hhbRK6bhWRb&t=1191
Sometimes they can be a real PITA to remove even with the small removal tool so needs mole grips or spanners, one on the core drill bit shaft and the other on the chuck. Using a rubber washer makes it easier so it doesn't fully compress against the core drill and are pennies to buy. It doesn't affect performance.
Also if you have the diamond coated erbauer it should have no problem with bricks, I used mine to do the cooker extraction flue, took some time to do but it did the job
A core drill will definitely drill through bricks 😂😂😂
He didn't say it wouldn't!
Yup, a core drill will definitely drill through bricks. 😂😂😂
i once worked for a council housing association contractor and we had to core drill hundreds of homes who didnt have an extraction fan , my right arm looked bigger than the left after a month ... its painful to hold up for a long time , and these were 70s builds
Pretty sure he said exactly that 😂
Would of been easier to hire the drill😂
Ha! Fortunately no, this way is much easier. 👍😂
would a macerator have been a good option here
I would use a macerator only if it is an absolute last resort. They're noisy and wont cope with the wrong things going through them. Also most plumbers would rather not go near the things for servicing or repairs.
Having seen them explode, not a fan. 😂
The core of this video was boring (sorry couldnt resist) 😅shout out to "your lass" for the mess clean up & to yourself for keeping the render clean, in all a nice tidy job.
Ha cheers! Drilling the new render was stressful! 😬
Fookinell
😂
Door opening in would have been much better/
Doesn't make much odds.
door has to open outwards to meet disability regs.
Think that's just for new builds, but sure someone can confirm. 👍
@@GosforthHandyman extensions included. no need to bodge it though anyway, do it once do it right!
Finally 🫶…been waiting all weekend for this one
Hope you enjoyed it! 👍
