4Z1WS CORE DRILL by BLUEROCK Tools 2 SPEED W/STAND CONCRETE CORING WITH: 1",2",3",4" DIAMOND WET CORE BITS

This set was exactly what I needed. I’m a structural engineer and I needed a coring drill that I could use for collecting my own concrete specimens from projects. I was nervous that the power draw might be too much for a standard outlet and i had this through a 100’ extension without a problem. I use the 4” bit with a 3/8 x 6” tapcon bolt to mount the rig on vertical surfaces. No issues whatsoever even when I go through the reinforcement. It’s not exactly light 30-40 lbs with the bit installed so it helps to have two people to mount it, but carrying it is no problem and transports easy. I am really impressed with the feel and quality of the drill. I wasn’t sure how it would feel and if it would last. I’ll be sure to update this post if I have any problems but so far I’m very happy with the value of this product.

Using this core drill for rock samples. So far its performs well with the factory core drills and the stand is really excellent. A great value for the money.

This core drilling assembly is being used for different size conduit holes in foundations of homes. It is easy to use once you get the hang of it and creates a precise hole. We used to hire an independent contractor for some of the drilling we needed but this setup will eliminate the need for someone else to do that work. Highly recommend.
