PURPOSE: A method for processing a hole of a printed circuit board by a hole processor is provided to reduce a processing time by mounting a drill on a spindle block. CONSTITUTION: A worker loads a backup board on a table, installs a plurality of pins on the backup board, sets one or more processing products in a predetermined position of the backup board, and installs a carrier including a plurality of drills in a front portion of the table. A main controller stores corresponding data into an auxiliary memory and sets up a work condition on the basis of the stored data when drill data, a hole film, and a program card are inputted from a data reader. The main controller moves the carrier to a lower end of a spindle block by driving a servo motor for moving the table. The main controller mounts the drill on the spindle block by driving the spindle block. The main controller locates a position of a hole of the processing product to the lower end of the spindle block by moving the table. The hole of the processing product is processed by using the spindle block. The main controller counts the used numbers and times of each drill. The used numbers and times of each drill are displayed on a monitor.
