FIELD: mechanical engineering. SUBSTANCE: rotation axis and axis of self-setting of blocks 3 are positioned outside of blank 1. The eccentricity of the axis of self-setting of the blocks exceeds the radius of the opening to be machined. The tool is provided with a sprayer of cutting fluid. The spryer is fork-like and received in the opening of the housing. Holders 4 are L-shaped and secured to housing 5 and blocks 6 to form cantilevers. The outer surface of the holder is provided with grooves for spring 7. The cross-section of the grooves is semicircular. The opposite side of the grooves are provided with flat flanges for securing blocks 3. EFFECT: enhanced efficiency. 7 dwg
