FIELD: mechanical engineering.
SUBSTANCE: devices for machining internal holes, namely for removing sharp edges in non-circular outlets of inclined holes in a thick-walled tubular billet. The device contains a tool for removing material, used in the form of a cone or drill, inserted into the chuck of an angle driver. The driver is fixed in an enclosing device designed to be brought to the object for removing material, in particular, the sharp edge of the internal inclined hole. The device is equipped with a means of monitoring the object. The device has the ability to lower the angle driver on the area of the object to remove material.
EFFECT: rounding of edges at sharp angles of inclined holes inside a thick-walled pipe is provided.
