    The invention relates to accurate
    machining holes in the metalworking industry.
    The aim of the invention is to improve the reliability of fixing, simplifying the installation of the cutting plate in the housing.
    Figure 1 shows the scan body; in figure 2-- section aa in figure 1; on fig.Z - section bb in figure 1.
    The scanning body 1 has a recess limited by the supporting arc surfaces 2 and 3, into which the clamping biscuit 4 is placed, the supporting arc surface 5 of which has a radius smaller than the radius of the arc surface 3 of the notches. On the shank side, the cracker is provided with a semicircular protrusion 6, which fits tightly to the support surface 2 recesses to the body for fastening in the head by means of a threaded bolt 7 with two opposite thread directions. In the recess of the clamping rusk 4, there is a cutting round plate 8, which the rusk presses against the protrusion of the housing 1.
    The notch in the clamping cracker 4 has a width smaller than the thickness of the cutting plate 8.

    The radial installation of the cutting plate 8 is carried out with the aid of a wedge-shaped adjusting member 9, the longitudinal movement in the recess of the housing 1 is carried out by means of a screw 10. The guide bars 11 and 12 are arranged around the circumference of the housing of the sweep.
    A simpler radial installation of the cutting plate is thus achieved due to the fact that the clamping dies clamping the cutting plate in the recess can only be rotated by means of a single fixing body, thereby changing the radial distance of the cutting edge of the cutting plate from the axis and the working diameter sweep. To prevent this diameter from changing, under the action of cutting forces, the clamping dough must be strong and strengthened so that the protrusion on which the rushes rotate will not change its central position inside the head notch either by the action of the cutting force or by the installation organ, which is achieved by covering the projection of at least 180.
