Wow Milwaukee 48-20-5055 4-Inch Core Bit

Milwaukee 48-20-5055

I used this product to drill (10) through holes in 14"-thick concrete stem wall (we used the milwaukee extension bar and center piece). It works perfect! no water needed. In few holes, we encountered 1/2" rebars and the core bit (carbide) cut them. You do stop every ~3-in at a time to clear the concrete. We used the small milwaukee 1" hammer drill to drive the core bit (remember you are only cutting a thin curf so you can core 2-1/2" dia using a 1" rated hammer drill).
