PROBLEM TO BE SOLVED: To provide a drilling machine which can bore the side end surfaces and end surface of the work of a panel and others automatically. SOLUTION: After one side end surface of a work was bored by the first drilling machine 31, the work is conveyed from the first drilling machine 31 to the second drilling machine 32 by the first conveyer 34. Next, after the end surface was bored by the second drilling apparatus 32, the work is conveyed from the second drilling machine 32 to the third drilling machine 33 by the second conveyer 34. Next, by boring the other side end surface of the work by the third drilling machine 33, the side end surfaces and end surface of the work are bored automatically.
