Abstract
1410534 Kerf cutters DRESSER INDUSTRIES INC 4 May 1973 [8 May 1972] 21425/73 Heading E1F A cutter for mounting on the rotary head of a boring machine or the body of an earth boring bit includes at least two rows (1-8) of inserts 10 adapted for cutting concentric circular kerfs; the inserts of each row being arranged so that the distance between the nearest points 29 of adjacent inserts (cutting structure interruption) is less than 75% of the distance between the central axis 28 of adjacent inserts (pitch chord). In the embodiment shown a cutter shell 11 is freely rotatable on a gearing shell 12 locked to a saddle 13 and carbide inserts 10 have elongated head portions 27 aligned along the insert rows and parallel leading and trailing flanks to provide a cutting structure interruption which is less than the pitch chord, the inserts in cutting simulating a continuous line contact with the formations.
