    A tool for lapping internal surfaces of holes. Lapping tools conventionally have an expandable working portion for variable diameter operation. Known tools tend to expand in a barrel shape leading to inaccurate lapping. The invention seeks to avoid this by providing a working portion of a tubular tool with slots in a plurality of rows each having several slots. Slots in each row are staggered relative to those in adjacent rows.

    one
    The invention relates to toolmaking, in particular to tools for finishing a hole.
    There is a priter containing a conic needle that carries a cylindrical shirt with a cut 111 that has been carved with diamond chips.
    A disadvantage of the known tool is that during unclenching 10, the jacket loses its cylindrical shape, which reduces the machining accuracy,
    The purpose of the invention is to preserve the cylindrical shape of the shirt in the processing process.
    The goal is achieved by the fact that the through slots are made rectangular and are located parallel to the generatrix in several rows, while in the adjacent 20 rows the slots are located relative to each other in a checkerboard pattern.
    FIG. 1 shows the lap, general view; in fig. 2 is a section A-L in FIG. in fig. 3 section bb in fig 2. 25
    () WIPER
    The lap contains a conic needle 1, a cylindrical jacket 2 carrying a diamond-carved diamond crumb with through slots 3 while the nail slots are made in the form of nests and are parallel to the generatrix several in a row, while in the adjacent rows the slots are displaced relative to each other in a staggered pore dke, In the shirt 2 fixed rod, t, transmitting rotation with a conical needle. 1 shirt 2.
    When the priter is in operation, when it is necessary to increase the outer diameter of the jacket 2, the conical needle 1 is displaced. As a result of placing the nests several times in a row with the nests of the adjacent rows displaced relative to each other in a checkerboard pattern, the shirt retains a cylindrical shape.
