Abstract
A dental root canal cutting tool is formed by mounting a wire rod (3) onto a chuck-head (5). The chuck-head (5) variably rotates and advances the wire rod (3) into a guide (6) having a guide hole (7). A whetstone (9) is disposed proximate the outlet of the guide hole (7) for grinding the wire rod (3) with a taper-like shape. A space exists between the cutting edge of the whetstone (9) and the axial center of the guide hole, which varies in response to the advance of the wire rod.
