"This one of the cheaper diamong core drill sets available so I didn't have particularly high expectations. My first job was a 50mm hole through an 11" cavity wall with clay stocks externally and flettons internally. The core drill did tend to bind on the clay stocks but regular clearing solved the issue. When it came to the hard flettons that I'd expected to give problems the core drill flew through with very little effort. The 110 bit also proved to be well up to the job an this wall giving similar performance. Both holes are clean and true - what more could you want? I don't know how long the bits will last but they appear to show no wear at present so all I cansay is that they seem be excellent tools for the price."
"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."
