Armeg Core Drill Set Here: amzn.to/33KHDUH
Good vid, thanks. Agree the use of smooth bore ducting - much better airflow than corrugated flexi. A slight fall towards the outside might be useful to drain away any condensate.
I always tell em to get a builder in to core drill, then I go and do the rest lol 😂 I hate core drilling too.
Good plan
I have thst titan for my dirty work and she loves a bit of it .
The hammer function sometimes goes a miss but after a talking too she's back at it. 3 years of abuse so far !
Re: Sleeving earth I always sleeve and terminate into a Wago yellow 2 way (773 Series) easy to get probe into to test afterwards etc... and also port available to loop off/out if required.
Like the idea of the ducting. Good vid.
I was using one of those non safety clutch Titan drills for core drilling not so long ago - and it jammed, span round and caught my chin nearly taking teeth out and giving me concussion. Had to sit down for 5 mins. If I'd been standing on the top of my ladder like you I'd heve been in hospital! Buy some scaffold, drill from inside or go on a ladder course... You are right though. Core drilling is the pits. One day I'll invent a drill rig for doing high up holes. I'll be a millionaire :)
I have the same Titan, bought it to do a couple of core drills, it has the safety clutch.
It's already been invented. You attach a mount to the wall and the drill attaches to the mount. The mount then takes the full weight of the drill.
With the earth i always put it into a wage connector, however if it in small enclosures such as fans etc... then you can use the Ideal push in connectors as they are very slimline. Good vid :)
Thanks! Nice to know how other people do it
Great video 👍
Thanks!
Do you need 3 amp fuse fuse protection on lives ( perm and switched ) with the manrose fan?
Good job.
Never be tempted to push too hard on the drill, let the drill and bit do all the work.
i got a cooker hood extractor fan there is a floor upstairs so i want to run the extractor through the ceiling then it needs to go 90 degrees and about 1.5m to the wall. do you need additional fans up under the floor boards or not?
Thanks for sharing this. Very helpful. Appreciate your time putting this together.
Core drilling does wonders for your tennis elbow 😄 I do exactly the same with the pc earth gives a test point
😁
Sometimes I do the same with the earth but if there’s room I’ll put a 2 port wago (push fit not lever) on the end
I don’t like to have the cpc bent over in the fans, I just put a white small wago on it, afaic the cpc is needed now,for testing and better for short circuit if the cable gets cut.
Good tip! Thanks for your comment
Nooice!
The cause of your problem is using a follower. Change the follower for a masonry bit. That looks light soft brick. With an extension bit, you should have flown through it!!!
good video
Thanks!
THAT DRILL IS DANGEROUS THAT DRILL LITERALLY THROWED ME OFF THE LADDER IM HAPPY WITH BOSCH NOW
I was about to use my 25 year old (unused) heavy sds drill to cut a 4” vent hole until I read the accounts of various people being injured. As I wasn’t sure it had a safety clutch I borrowed my neighbour’s modern one. I made sure the ladder was secure and held the drill slightly away from me. However, the safety clutch kicked in twice - not by hitting a tough spot but by the drill twisting and sticking into the sides of the cut groove (tired arms I guess). Make sure your sds drill has a safety clutch!
Ha, I've also got an old, barely-used SDS drill that I was planning on using for some core work (cooker hood). Just checked it, no clutch, dammit. No way I'm doing a 150mm hole at height with that.
Best thing I did was getting a corded Makita core drill when my old DeWalt SDS complained on a test hole. Worth every penny.
There is a Makita dust extractor accessory, but it costs as much as the drill - for professionals only (it is very strong)
Ive got that titan drill. Always on offer at screwfix. Bit much for just doing 6mm holes though lol, but at the moment my cordless isnt man enough for hard bricks!
Yeah it’s super heavy! 😅
@@artisanelectrics but it does so many other things, I took up some broken concrete with it, really useful.
You should buy the dustless core cutter from screw fix and a core drill
Glad to see I’m not the only one who is using the Titan SDS for core drilling, not wasting the nice Makita core drill on anything other than thick concrete anymore!
I always sheath the earth for fans etc and leave as is.
Are you doing your pilot holes inside out?
Love the vid btw :)
Jordan, where are the grill covers from, they might be better with two shutters than four, to stop the chattering
always found it really hard to get the hole perfectly straight. So I suck a level to the top of the drill😂.
Despite the naysayers.. using a budget drill for coreing is common sense if you don't need to be doing them every week, sometimes I'll have to drill 115 through a shipping container wall, it kills even the best drills after a while.
I’m guessing your waiting on “you shouldn’t stand on the steps like that to core drill” comments mate 😅😅
Of course! 😂 I already put that part out on Instagram to pre-empt the comments! 😅
I commented but that's only because we love ya Jordan 👍
Also get high rise ducts so much easier
Get yourself a longer stepladder man, had too many close calls when core drilling.
HSE Gestapo are coming after you... has that Titan got a clutch? The speed's rather slow on them... A dedicated core drill would soon pay for itself
Yeah but I only do maybe one or two per year so it’s really not much point to buy a machine
@@artisanelectrics Yeah I know the feeling... The Bosch GBH2-26 SDS @ £125 is a good compromise though... and stop standing on top of those steps :-)
Usually I hire a Makita core drill and can or bit? Whatever it’s called from Hirebase. Good to get a dedicated tool makes lighter work of the job. I used to use a Titan too but killed it after coding and chasing, lasted 3 years though so not bad for £50 👍
HAVs Rating on the Titan drill?
If you look titan do a few sdss like that some have clutches some don't when I read the screwfix reviews some said my model had a clutch but screwfix didn't recommend itfor core drilling.. I can confirm mine has a clutch but it didn't work when the drill is upside down. 😮😅
You should have said you drilled from inside to prevent blowing the bricks, we would believe you😀
Nothing wrong with folding earth over in class 2 fittings it’s there if ever needed and no way it’s going to short onto anything much better than cutting off which I quite often see. I always use black as neutral as that’s the way it was always done just like blue was neutral in old 3 core. There’s no regs that say you can’t just personal preference. At the end of the day it don’t matter what u use as long as it’s marked up. We all know blacks never neutral just like blacks never earth and blues never live, unless when a switch line and identified
Hi, could you not have got away with one core hole and put a Y connector on ducting inside, I use black for neutral as I’m old school .
Then you can get backdraft problems
@@artisanelectrics Could you have fitted 2 inline non-return flaps at the Y connector.
Do you ever have a problem with condensation gathering inside the ducting/inline fan? We do alot of inline fans and have found sometime condensation builds up in the ducting and can run into the fan which puts strain on the motor. We have started to mount the fan on an angle so the fans don't break and only mount ducting on an angle too but still struggling to get condensation build up out of the aluminium ducting. Any tips? 🤔 Great vid as always! 👍👏
Actually this was one reason we installed the in line fans as they are a lot less prone to condensation than ceiling fans, originally on this job there was a ceiling fan in one of the bathrooms which was ducted vertically straight out the roof and condensation was a huge problem! The customer originally called us complaining the fan wasn’t working and when I opened it up about half a litre of water poured out! So we recommended changing to inline fans! Much better. With vertical piping you can use condensation traps but need somewhere to pipe the overflow out etc and it’s a lot of faff.
I think you should have used insulated ducting, I would never use non-insulated ducting on an extractor fan, imagine how cold the outside of the ducting in the loft is going to be in the winter. Including the solid pipes you used - they could be freezing in the winter, with hot, moist air going through them for ten minutes or more each day there will be loads of condensation forming inside. So I would have put some sort of insulation around all of the solid pipes you used as well as using flexible insulated ducting for the flexible parts.
Most instructions I've seen recommend 3⁰ downwards angle through wall. If straight uo through ceiling and roof, a dogleg to catch moisture - but need 150 mm fan for that. In line ceiling fan far better
I do same as you with the earth mate
Top bloke!
I do that too.. Extra-long sleeving and fold it over.
I’d runaway 😂 HAVR say nooooo
Who is responsible for drilling a bathroom extractor fan hole electrician or a builder ?
I cant tell if one of the grills was slightly higher than the other or is that just me, apart from that another smashing job mate!!
Yeah it was 2mm out well spotted! 😂
Artisan Electrics I only noticed because I’ve done it once and it was a lot more than 2mm🤣😂
Reece Cooper yeah very had to get them exactly the same when drilling the holes and there’s a bit of play in the grill fixings but not quite enough 😅
@@artisanelectrics Had a guy drill through for two fans, bathroom and toilet. He drilled them so off level with each other that when I put the grilles on I had to cut the spigots off so that at least they lined up even if the ends of the ducting underneath didn't 🙄
I never drill from both sides-I would of drilled from the loft all the way through, plus u save your arms as well, as the drill would have been below the shoulders.
Not a criticism, as everyone has their preferred method, good luck.
Yeah I was just worried about blowing out the bricks on the outside!
I start from inside, go most of the way, do an inch or two from outside to avoid tear out, finish from inside. But, as retired DiYer, I have the time. I'd certainly use a far better ladder. I'd hire a quick scaffold tower from HSS if I had any qualms about such a job
You missed the most important info. How long did it take you to drill that hole?
Is that an ordinary run of the mill electric drill or is it SDS. (RDS?)
Dry diamond core drills are not SDS. You don't use hammer action. Other types of large hole drills do use hammer
When with Diamanten You need Speed not Hammer Power
By Diamanten its like a flex
What do you call a former farm machinery enthusiast? An ex-tractor fan.
I'll get my coat...........................
Buy yourself a decent core drill (Marcrist DDM1 for example). You'll spend less than a quarter of the time you are currently spending drilling those holes
Electric Magic yes agree and get a Marcrist diamond bit.
They do a 450mm long bit ,do it all from one side.
Even do a extractor adapter to suck the dust away.
Why not just join the ducts after the fans with a Y piece. Only one core drill then 👀
Yeah but then you need a backdraft flap etc otherwise you will get one fan blowing air into the other bathroom
My advice when core drilling is find a plumber. Usually I can't find one and do it myself. 🤣
Good advice! 😂
@@artisanelectrics Have a great day a great day indeed , enjoy your videos.
Jerry McMorris thanks! 😁
Don't think I would chance it with a non-clutch drill.
I'm here because I nearly broke my leg yesterday drilling a core hole with that titan... never again
Jordy never use the titan drill again... I broke my wrist on the same model it has no clutch...
Get yourself this: DeWalt D21570K-LX Only about £120 on Amazon, so much lighter and quicker. I also bought the dustless core set - Marcrist Core Drill Bit Set & Dust Extraction Unit 9 Piece Set, that my trusted electrician reviewed and it's excellent too.
Cool I will check it out thanks!
+1 on the dust extractor. It sucks over the bit keeping it cooler so less likely to snap teeth and clearing the dust out makes for a much more efficient cut, it made core drilling so much easier (and cleaner)
Theyre over £200 at screwfix!
@@loosecannon5813 The core drill is only £120. Have a look at the review by My Trusted Electrician, those dust free cores are worth every penny!
Buy yourself a proper core drill, not actually to expensive, i fucked my wrist up a few years back core drilling on a sds when the clutch failed. I use a core drill company now too, charge between £60-£80 a hole for a fan, usually through it within 10mins with there dust extractor no cleaning after.
We let the plumbers install the fan itself, and we just make the electrics
2:00, NEVER core with battery tools! They just don't have the power or the longevity of mains power tools.
I do like your idea of a cheap drill solely for coring though. 🤔👏
Thanks! Yeah I wrecked a makita battery drill trying to core with it! 😬
I used my trusty mileaukee 18 volt to do a few 4 inch core holes...... One of the old all red loctor versions..... Did it easier than any sds i was given only problem with it was charging the batterrys afterwards..... Luckaly most the sites i was on had fridges in the canteens so put the charger and batterys in the fridge on charge worked a treat.....
I wouldn't use those big wipes on plastic, I used them once and it ruined the finish
Interesting thanks!
Did the customer come back............
Can you just use a crappy corded drill with the core bit? (Bodge diy) 😇
Buy yourself a proper core drill . 1000x better definitely worth it trust me .
Thanks!
Use the correct tool to cut the core. You’ll soon buy one when that crappy SDS binds and dislocates a couple of digits. Also helps the environment with not buying multiple failed tools.
The flappy grills are called gravity grills 😀
😂 thanks
The Titan SDS has a clutch so will slip rather than take you for a spin
Absolutely hate core drilling, shame u don't use an extension so you can go through in one go
It was a double skin wall so going through in one go wasn’t really an option anyway
Artisan Electrics it is an option with an extension as suggested
I bet the loft was dusty! 🤣
Artisan Electrics definitely can do a double skin wall with an extender.
Yes! 🤪
Leaving sleeve longer than the core and then bending round. Not acceptable.
The earth needs to be terminated into a connector block 👍
Holes to close together, building regs are 300 apart, all ducting in the loft needs insulation!!! 🫣 shocking
