Abstract

PURPOSE:To eliminate the necessity for using a stop pin or the like and surely perform burring at removal of burrs in two holes, crossing and communicated to each other, by inserting tools, equipped with a burring edge met to each hole, into the holes and sliding these tools. CONSTITUTION:The first drill hole is drilled in a base material 10, while the second drill hole, crossing and communicated with said first drill hole, is drilled in said base material 10, and then the first burring tool 81, both formed to shape fitted to the first drill hole and equipped with a burring edge part 83, is slided axially of the hole in the first drill hole to perform burring work, subsequently the second burring tool 82, both formed to shape fitted to the second drill hole and equipped with a burring edge part 85, is slided axially of the hole in the second drill hole, thus the above described communication part is performed burring.
