To solve the problems of the conventional manual reamer, wherein although the reamer is often used for quickly enlarging the bore diameter or connecting two or more holes to form a large hole rather than obtaining a high-accuracy bore shape, large burr is frequently caused in this work, and a radio cutting pliers is used for deburring, resulting in large loss of work time due to frequent shifting the tool from one hand to the other in the work requiring quick work.

This reaming cutting pliers uses a manual reamer having a function of a clip. According to the invention, a rod-like part holds a material to be held in a split surface 11 and a split surface 12 while maintaining sectional secondary moment hard to bend. A hole in which the rod-like part is inserted can be expanded by rocking the split surface 11 and the split surface 12 in the direction of going away.
