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. 👍🏼

Someone below mentioned it, kickback control, but didn’t quite get to the optimal solution. Left or Right there is always a drill-handle orientation that will let you catch the kickback, which is the only way the clutch will ever engage. For the hole here, rotate the whole drill clockwise 90, then release the handle and rotate that another 90 so it is pointing straight up. Now you can engage the drill with your right hand and the handle is such that kickback with be straight into your palm, allowing the clutch to trigger rather than having it rip away from your hand. Nice video!

It’s a good idea to put a slight rise, (out to in) on the hole, not level when to be used for vapour exhaust. Any moisture left in the ducting when machine stops will drain to the outside of the wall.

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.

Great and good quality video again . 👍 👌

Good explanation! A little advice: in the future, try to move the handle in 90 degrees to right or left. In case of stuck or something you will control the drill much easier Good luck!

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!

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?

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.

spraying water occasionally, helps with dust and provide some cooling to the the core drill.

Easy 👍 please do pebble dash concrete next 😂😂😂

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.

how well does this work in fiberglass reinforced concrete and what happens if you run into rebar?

Would you recommend going from outside then doing the inner wall from inside out over if you had pipes and cables nearby?

Is this the right saw bit to cut through stucco, too?

For the pilot hole bit (8 mm) does that bit need to be diamond tip also? Or can I use the pilot bit that comes with the core bit to drill the pilot hole?

Can you give any tips for enlagering a previous hole?

What is a recommended hand drill machine? I am asking about lowest watt machine required for a hole saw bit to drilling in properly?

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.

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

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?
