"I bought this core set as I was putting an en suite in my bedroom. I used the large one for the soil pipe and the small one for the shower outlet. Both cut very well using an SDS drill. Much better than hiring."
"This is a top quality product and as good as anything i have hired. Removable foam slots allow you to add extra drills and extension bars. Have used my 117mm core to drill through kitchen floor 5in of concrete and two 4in brick walls at a angle of 45 deg to the depth of 32in and i still have a perfectly good core drill to use on many more occasions."
"I was thinking of buying a decent 4" core drill instead of srtugling with cheap ones. So, having read all the reviews on these, I now have a set. I ordered on an evening, then had them to use the next day."
"What a kit this is. Ignoor all the people that say this is rubbish. The reason being they are not using a proper core drill ( i got the makita). Once you bought a proper core drill. These cores work a dream. I've used this over 2 dozen times to core holes for boiler flues and vents on various bricks and concrete blocks and the teeth are still look good. Should hopefully get another 2-3 dozen uses at least. Most definitely worth it even if you just need the 117mm core drill bit. Plus the box is a real bonus."
"Ive looked around at the more expensive kits and wasnt sure about this one, but at less than £70 i'd thought i'd give it a go. The perfomance of these are fantastic, cut through brickwork like a knife through butter and at half price these are well worth the money."
"Used the 117mm bit twice now and worked well both times with no problems. Comes in a neat case with all the accessories. Don't use it alot, but at the price it is good value, and saves on the cost and time associated with hiring one. How it will stand the test of time remains to be seen. But to date i am more than pleased with its performance."
"I haven't used the larger of the cores yet but the performance of the other two is fantastic. I used the 38mm one to cut holes through two layers of brickwork for low and return pipes to a boiler and it took around two minutes for each hole. The 52mm core was used to cut a hole for waste pipe from a kitchen sink and it took less than two minutes. I did have to fit the extension bar that comes with the set though as the standard attachment is only long enough for a single skin wall :) Both cores were used with a Titan SDS battery drill set on rotary (not hammer)."
"Used the 38mm core drill to bore 3 holes through a 15 inch thick concrete slab, still going strong on the third hole. Tip, the drill will only do about 5 inches with the core in place so every few inches I broke the core and lifted it out of the hole with a vacuum cleaner."
"Bought this diamond core kit as I needed to drill a couple of holes through a wall for waste pipes - the walls were already tiled so I didn't want to set about it with a lump hammer and chisel. The kit is very easy to set up and went through the wall like a knife through butter, leaving a nice neat hole on both the inside and outside of the house, so rather than having to cement up a big hole like you do if you use a hammer and chisel, I was able to just smear a bit of cement round the pipe with my finger - job done! I'm not sure my customer would appreciate the difference - after all, it' just a pipe sticking out of a wall for most people - but I thought the finish was so much neater. Not sure about reliability - time will tell - but so far I'm well impressed."
