Abstract of the Disclosure The cutter head of a reamer carries a circular tool bit and two guide members. Each guide member has an outer-most edge at the furthest distance from the center of rotation of the tool and slanted edges inclined at progressively greater angles from the outer edge towards the front of the tool where the initial cut takes place. The first slanted edge, at an angle of less than 10 degrees and preferably between 3 and 5 degrees, intersects the outer-most edge at a point which lags the extreme point on the tool bit by about 0.4 mm in the direc- tion of advance of the tool. The first slanted edge extends at least to the radial plane containing the extreme point of the tool bit. Thereafter, a slanted edge at an angle inclined between 15 and 25 degrees extends in the forward direction, to be followed by a third slanted edge inclined at an angle to the outer-most edge of between 30 and 75 degrees. The exact angles of inclination are determined by the diameter of the circular tool bit, which, in turn, is determined by the material to be cut.
