Review on CBW122H Diamond Concrete Masonry Threaded: Supreme Performance for Ultimate Durability by Justin Jeppi
2 " hole in 4 " concrete
It took a while, I have a cordless drill and 2 battery packs. I had to use almost 4 full charges to complete the job. Second, you need a drill adapter. I had to order separately. Once in place it worked fine. When we said we used a piece of wood with a V notch to hold the drill in place, but after that it was fine. Maybe about 1 1/2 hours total to get through 4 inches of concrete.
Pros
- HF welded diamond segments for the bond strength needed to effectively cut concrete and other soft to medium hard materials
Cons
- No instructions
