PURPOSE: To provide an electric deposition reamer which can develop the characteristics of each abrasive grain to the extent and can carry out working with the exceedingly high precision.
CONSTITUTION: Diamond abrasive grains 5 having high hardness are electric deposited on the tapered part 2 and the back tapered part 4 of a tool base metal 1, and CBN abrasive grains 6 which has the nearly equal particle size to the diamond abrasive grain 5 and is stable at high temperature and possesses the excellent trueing performance are electric deposited on the straight part 3 of the tool base metal 1 through the electric plating method such as Ni plating, and a spiral oil groove 7 is formed on the abrasive grain electric deposited part of the tool base metal 1.
