Basic's of How to core drill

lay out holes for core drilling by marking center of hole
When laying out holes for concrete core drilling everything relies on center measurements. A core drill bit is round so it follows logic.
Some things you might not know:
A) When possible use a lead #2 pencil to temporarily mark your core drill hole center's.
B) Be accurate. Once your core drill bit touches concrete the damage can not be reversed.
C) Then (when your sure about where the holes need to be located) use a permanent black magic marker to outline the diameter of the hole. Do this so your marks are not washed away by the core drilling process. Wet Concrete is harder to leave a lasting mark on.
