I am very impressed with this tool for the price. This was my first time using a core drill and I used it to drill a 4” diameter core through a 9” thick concrete retaining wall. Worked very well. The water hose did not leak. The clutch engaged once when the bit bound up and it did not twist my wrist.

I bought this drill with a 3-9/16 coring bit to put in a railing at a very remote location. The drill worked flawlessly. With the water feeder connected to a hose I was drilling 6"+ deep holes in less than 5 minutes. After twelve holes (one hour of straight drilling) in 95 degrees weather, the drill was only a little warm and could have kept going for much longer. I'm happy to have this as part of my tool collection.

We use handheld rigs all the time. drilling 1.5" thru 8" for pipe penetrations thru concrete slabs, walls & hollowcore. Not really supposed to use a bit over 4" I believe with this unit. But they work. Have been thru several hand helds: Diamond Products Core Bore, CS Unitec (Eibenstock), Kor-It, Core Bore WEKA, etc.. Probably tried them all. We might get 2 years out of the big name brands before they are garbage. I have a trashed Diamond Products Core Bore sitting in my office now that is about a year old. Granted, we do use the larger bits and understand that wears the machine pretty hard, but we get almost same life span from the BlueRock. This one last almost as long at 1/4 of price. I paid around $1,200.00 (Eibenstock) - $1,600.00 (diamond / Core Bore) for big brand hand helds. This is by far the best VALUE. Even if you rent from United Rentals / HERC / Sunbelt, etc.., your going to pay a couple / few hundred a week.

Excellent item I have brought several of these and they are just as good if not better than the name brand competitor.
