    摘要： The drill of the present invention has only one cutting discharge groove (11) formed in the outer periphery of a bit (10). A leading edge protruding farthest towards the tip in the axial direction in a tip flank (12) is composed at a single point and located on an axis (O). When bit is viewed from the tip side in the direction of axis, tip flank is in the form of a multilevel surface composed of second through fourth flanks (14B, 14C and 14D) arranged along the peripheral direction, and a reverse side first flank (14E) surrounded by second through fourth flanks and intersecting with axis.

    摘要： 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 direction 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.

    摘要： A plurality of cutting plates are mounted in a recess forming a mouth at one end of a drill bit and each cutting plate has a plurality of cutting edges. The drill bit mouth provides chip removal. In the cutting position, the cutting plates are arranged in a plane extending in the direction of the axis of rotation of the drill bit and the cutting edges are arranged in a step-wise manner. The cutting plates can be turned for arranging different ones of the cutting edges in the cutting position. The cutting plates extend radially outwardly from the axis of rotation with one plate adjacent the axis of rotation and the at least one other plate extending radially outwardly from it. The cutting plates have a parallelogram shape in the axial plane of the cutting position. In the cutting position, cutting edges of the cutting plates are in parallel relation to one another with adjacent parallel cutting edges on adjacent cutting plates being in contact with one another. Within the cutting position, the cutting plates are adjustably displaceable in the radial direction. Further, the cutting plates can be secured in the desired position.
