Below is a picture of one of our core drillers here in North Carolina using one of our 10" core drill bits to core drill a concrete wall. Notice the rig is attached to the wall by use of a concrete wedge anchor. This particular project called for a redo, in other words the contractor ordered 10" core drill holes then a few days later discovered that a 12" hole in the wall is what they really needed. Of course we cut him a break and made a concrete pipe which is pictured below.
