"Bought these for a rush job ,read reviews yes seem ok . THEY are GREAT had to buy the 78mm cutter for one job , went through a 550mm wall of concrete block stone and brick in about 20 mins , have since used the 117mm cutter to core through 16 grey conc flags 50mm , only thing that has worn off is the paint on the cutter . One thing to add is get a decent core drill ,bought the TITAN 5 KG drill which comes with core bits ,used on 3 holes then packed up , went and bought the DEWALT Bullet core drill did the rest in record time , (review to come). To quote YOU GET WHAT YOU PAY FOR is absolutely true . Have only given 4 stars for reliability as have only had them for 2 weeks ,but first impressions gets a 5"
"Purchased these because of the excellent value & required to punch a few holes through some brickwork. Use my standard sds drill variable speed & clutch, they performed very well & exceeded my expectations. I have worked for over 45 years in the plumbing trade & used some very expensive kit in this time you can't go wrong with these if you use them PROPERLY."
"To be fair have only used one of these once but that was enough to realise the ease with which these babies eat through brick and block. Use the SDS drill with a long thin drill from the inside to locate where the position of the hole should be from the outside. Put the core drill on and drill from the outside. Job done on a double skin wall in less than a minute. Very little reparation work to be done. I reckon that I only have to use these drills half a dozen times (if that) and they will have more than paid for themselves. Erbauer always seem to give me great value for money."
"After pacing the room, trying to work out the best way to cut a 110mm soil pipe (for a loo) and a pair of 40mm waste pipes for sinks and bath/shower I finally went for this all in one set. Teamed with my tried and tested (£90 Screwfix bargain) Dewalt SDS drill what I thought was going to be a 'pro only' nightmare turned into a breeze. Three perfect holes (at 390mm depth) drilled in an hour. And the tools show no sign of wear besides scuffs on that Erbauer blue paint. By all means buy cheaper, but for an easy life, these are the bathroom redesign tools you're looking for."
"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."
