Drilled a 4 1/8" hole through 12 inches of engineered stone and cement block in about 35 minutes. I started by using just the pilot bit to drill straight through. Started with the core bit and pilot bit as slow as the drill would go to etch into the exterior until there was enough of a groove to keep the bit stable, then took the pilot bit out. I stopped often to cool down the drill bit with water and mist the cement. Went slowly using just enough pressure to keep the bit level. Used with a very inexpensive, 5.0 Amp corded drill on rotary, only using the hammer function to drill initial pilot hole. Result was a very smooth cut out, no splintering on either side.

Cuts well, heavy tube with a lot of cutter material. Long enough to core through block.

I was able to drill two holes through five inches of 20 year old concrete using this core bit. I wet-cut it by running a slow stream of water from a hose to the edge of the hole. It takes a long time (maybe 40 minutes?) to cut through that much concrete, so I had to do it in a couple of sessions so that I didn't burn out my drill and so my forearms could recover. My only knock on the product is that the pilot bit is essentially useless. For the second hole, I just used a guide on two sides of the core bit to get the hole started, then was able to continue cutting with the guides out of the way. This bit requires a powerful drill with a second side handle to hold it steady. I used a Dewalt hand drill with 1/2" chuck. Be prepared for the bit to bind, especially if you are boring through several inches of concrete. Also, be safe and make sure your drill is plugged into a GFCI protected outlet, especially if you are wet-cutting.

Massive tool. Make sure your drill is up to the task. Cut right through brick with perfect hole. Only rated 4 stars because not sure how many cuts it will make.
