Abstract

The tool (100) has a slender support member provided with a front portion (102) and a rear portion. A pair of guide members (130, 132) is transversely arranged on the support member for applying pressure to relative semi-cylinder shaped surfaces of two offset deep holes to stabilize the front portion. Transmission mechanisms (112, 114, 120) are placed for transferring power from the rear portion to the front portion. A milling cutter (110) is provided for removing the rest material between the relative surfaces to form a passage of a long elliptic section in length direction of a deep hole. Independent claims are also included for the following: (1) a method for providing a deep hole with long elliptic section (2) a cooling stave for shaft furnace i.e. metallurgy blast furnace.
