“I had to drill through a 6 inch thick flat concrete roof to install a 4 inch drain. I used your 4-1/4 inch hole (core) saw. It drilled quickly using a HD 1/2 inch Milwaukee right angle drill turning at about 500 rpm. I must have hit rebar or steel mesh several times -- when I did the drill jumped around. But I got through it faster than I thought I would. Project completed much faster than expected.
I would recommend these saws.”
“The cup grinding wheels are excellent! They work better than the most expensive on the market and EDiamindTools products don't break the bank. I will definitely be buying a lot more of their products!!!!!”
“The bit that I ordered worked out perfect I was able to drill the hole I needed in order to install the pipe. The bit came sooner than expected so I got the job done early. thank you for a great tool and you will be hearing from me the next time I run into another core drilling project”
“I received the item in a couple of days and it did what I needed it to do, drilled a 9 inch thick concrete floor for a new shower drain.
Once I finished the work I saw I cut through a half inch rebar in the process and never even felt it. The tool is still good for more jobs, too bad that's all I needed it for.”
“Grinding floors to prep for new covering is not what we do, but because of safety concerns my crew of Radiochemists and Health physicist are all trained to work in a problematic enviroment. We were having problems getting the floor clean enough for the next step. I called, and talked to Vince Li, he was a huge help and made good recommendations on which grinding wheel to use and how to do the work. We bought the right wheel and have finally finished the floor. We now are facing the same job in a much bigger lab, and thanks to EDiamondTools we are ready. Special thanks to Vince!”
“I'm highly satisfied with the performance of the wet 1 1/2 Corning bit. Drilled 11', 9 separate cores, in 3.5 hours using a basic 1/2" drill. Rpm is the ticket. Hope to drill another 40 @ 18"”
“I have zero experience or knowledge working with stone. Saw someone on U-tube polishing granite. Googled and found your product. Don't know if I am wearing the discs. For a novice would be helpful to know what to look for as the discs are used. Had one grab on a corner and partially tore the fabric on outer circumference.”
“Great prices, good tools. We are a concrete polishing company looking for a great distributor! Do you offer bulk discounts?
Thank you Concrete INK USA”
