A cantilever type drilling machine is a type of drilling machine that is designed with a cantilever structure, where the drill head is mounted on an arm that extends outward from the column. This design allows for the drilling of larger workpieces and offers more flexibility in terms of positioning and movement of the workpiece. Cantilever type drilling machines can be used for a variety of drilling operations, including deep hole drilling, counterboring, and tapping. They are commonly used in industries such as manufacturing, automotive, and aerospace due to their precision, speed, and versatility.
