Abstract

908,869. Well-boring apparatus; jetting apparatus. KAMMERER, A. W. March 23, 1961, No. 10771/61. Classes 68 (1) and 85. With the earth-boring reamers or drilling tools of the referred-to U.S.A. Specifications 2,922,627 and 2,855,994 are associated structural units 100 that allow of the fluid operating the reamer or milling components of the modified tools to engage as one or more radial jets from nozzles 106 to impinge upon the wall of the borehole to remove material therefrom or to add material thereto. A number of modified forms of the tool shown are described.
