ABSTRACT:
A reamer includes a shank portion and a reamer head fixed to the shank portion. A cutting blade is mounted on the reamer head to project axially forwardly from the front end of the reamer head. A bearing guide pad is mounted on the reamer head circumferentially spaced from the cutting blade downstream with respect to the rotating direction of the reamer, and a sizing guide pad is mounted on the reamer head substantially diametrically opposed to the cutting blade. The axial lengths (L2) of the guide surfaces of the bearing guide pad and the sizing guide pad are both not larger than the axial length (L1) of the circle land of the cutting blade, the axial length (L1) of the cutting blade is not larger than the diameter (D) of the reamer, and the width (W2) of the sizing guide pad is not larger than the width (W1) of the bearing guide pad. The axial lengths (L2) of the guide surfaces of the guide pads are preferably 5 mm to 15 mm where the diameter of the reamer is 5 mm to 100 mm.
