PCT No. PCT/JP89/00888 Sec. 371 Date Apr. 26, 1990 Sec. 102(e) Date Apr. 26, 1990 PCT Filed Aug. 30, 1989 PCT Pub. No. WO90/02012 PCT Pub. Date Mar. 8, 1990.The present invention relates to an electrodeposited reamer tool (1) for use in precision bore processing. In this electroplated reamer tool (1), a work processing portion (3) in a reamer body is constituted by a finishing portion (4) having a cylindrical outer peripheral surface and a cutting portion (5) provided on the distal end side of the finishing portion (4) and having a tapered configuration, and abrasive grains (6) are electrodeposited on the outer peripheral surfaces of the finishing portion (4) and the cutting portion (5). In the electrodeposited reamer tool (1) is inserted into a prepared hole provided in a work, the prepared hole is enlarged by the cutting portion (5), and the inner surface of the bore is finished by the finishing portion (4). Accordingly, it is possible to form a precision bore of a predetermined inner diameter in a work without preprocessing the prepared hole with precision.
