Drilling machines are cutting tools used to create cylindrical holes. They are also called drill bits. Bits are held in a tool called a drill, which rotates them and provides axial force to create the hole. They are suitable for taking out cylindrical cores upto diameter of 6" (150mm) x 12" (300mm) high from rocks, concrete blocks or air craft runway slabs.
