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!)

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.

Excellent, prompt delivery

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.

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

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

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?

Does the job
