You sir are a Godsend. Instructions clear and concise. That is a job I have dreaded but you have given me the confidence to do it myself. Many thanks.

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!

@cuebj 9 ай бұрын

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?

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

@johnashton4086 5 ай бұрын

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.

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.

@NeilFirbank-en1yd Ай бұрын

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.

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?

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!
