110mm Diameter Sds + Tungsten Carbide Tipped (Tct) Core Drill

Maybe not the best quality, but did the job well enough through a concrete block wall. Cheaper than hiring the core drill, but needs a fairly powerful SDS+ tool to drive it.(Make sure the bolt holding the centre drill bit is tight!)

Bought this to cut a neat hole through my wall to fir a vent for a tumble dryer. My wall is brick outer and concrete block inner, and about 12" (300mm) thick. This drill / core bit went it through ok. It was not easy, it was hard work, but you have to take your time and let the bit do its work, don't force it and you will end up with a nice neat hole. Plus I was drilling in an awkward area, low down in a corner, so that did not help.It was much easier and quicker than doing by hand with a club hammer and cold chisel though.Quality seems ok, but not sure how many times you could use it before it starts to blunt?

This did the job perfectly and at a very good price. The right tool for the job. Excellent.

I had to make a whole for my kitchen hood exhaust. I looked for a lot of options and nothing was on my budget. Also didn't want to buy some expensive bit just to be used once.I found this one and thought to give it a try.I am quite good at DIY so I managed to get the exhaust hole through my double brick wall.It's not quiet and makes a lot of dust and a lot of mess and took ages to get through the wall but it did the job along with my SDS drill.It survived and it can probably do some more holes in the future.I for one give this small gem a 5 star value for money.It will do the job if you know what you are doing and don't mind the mess or the time it takes to finish.

This core drill bit works well, but it's a bit noisy. Ear protection is a must.

I bought this to core drill bit to cut drainage holes through a 100mm concrete block wall.I couldn't find out anywhere what depth of hole it would cut but I took a chance anyway at this price. As it happened it would cut successfully to a depth of 50mm to 75mm (the bit is probably about 80mm depth).By cutting, then using an SDS point chisel to clear the hole, and cut and chisel again I successfully cut 6 holes through the wall in probably just over an hour. The bit was cutting as well on the 6th hole as it was on the first and still has plenty of life left in it.I honestly thought that at this price it would maybe cut one or two holes before getting blunt but I was delighted with it's performance and certainly it's price.

Let's face it, this is cheap no it can't really be said to be intended to be used all day every day. It struggled on some particularly tough cinder block, so much so that after I'd done about 20mm I had to weaken the hole by drilling some 15mm holes all the way through. After that it coped pretty well.I then went onto some tuffeau and it did that with no problem. My final hole was some more tuffeau and it must have hit a tough spot because it struggled for a bit. However it got there in the end.It has done three holes and will probably do another ten, if I ever need them. So good value, cheaper than hiring.

Good value and did the job. I had to drill a hole for a vent pipe through a brick cavity wall. It is slow work but I speeded things up by usingmasonory bits to drill a ring of holes around the circle cut by the core bit. I drilled the holes after the core bit had made a ring about 20mm deep. I then completed the hole with the core bit. I got a very clean and neat finish on the brick work. Be careful that you have a good grip on your drill as you finish. My drill jammed in the completed hole and swung the body of my heavy drill around. The "core drill bit" is still good and at half the price of hiring it is good value.
