Disclosed is a manual hand ratch reamer for a dentist, which is used for forming a cylindrical hole in an alveolar bone of a patient upon implementing dental implantation surgery. The manual hand ratch reamer for a dentist comprises a front piece body, a rear piece body and a rotating driver which are connected one with another in a manner such that the rotating driver can be independently rotated with respect to the front piece body and the rear piece body. A reamer tip locking section of the rotating driver, to which a reamer tip is secured, includes connection means which is connected to the rotating driver by passing through the inside of the front piece body. When the rotating driver is rotated with respect to the front piece body, the front piece body is prevented from being rotated.
