Abstract
The pneumatic drilling device includes: a ram provided inside a cylindrical body so that the ram can move forward and backward therein; a spindle air motor provided inside the ram; a feed air cylinder mechanism for moving the ram forward and backward; and an air supply port for supplying compressed air to the feed air cylinder mechanism and the spindle air motor through an airflow path. The airflow path includes: a first flow path for driving the spindle air motor; and a second flow path communicating with the feed air cylinder mechanism for moving the ram forward and backward. The first flow path and the second flow path are separately and independently provided in parallel.
