| | Diamond Drill Bit Drilling Techniques |
 | | A template is made by drilling a pilot hole in a piece of soft wood or plastic, using the diamond core drill bit or by cutting a "V" in the edge of a piece of wood or plastic or drilling a hole in it the size of ther core drill. |
 | | The life span of all types of drill bits is affected by the hardness and abrasiveness of the material being drilled, the thickness of the material, plus the speed of the power drill, the amount of pressure used and the use of adequate lubrication. |
 | | If a drill bit develops yellow, brown, blue or black 'burn marks' around the tip, it is an indication of extreme heat and that the drill speed being used is too fast, the amount of pressure on the drill is too great, or the amount of water lubrication is completely inadequate. |
