BitRoller cone bits for hydraulic and air percussion drilling most promising for drilling in hard and very hard rocks as the imposition of shock loads on the roller bit allows to intensify the process of rock destruction and enhance drilling speed. Roller cone bit intended for continuous slaughter rotary drilling exploration, hydrogeological and other wells with the cleaning liquid or air slaughter.
Chisel consists of a body, to which are welded legs. On top of the housing is threaded for connection with the drill pipe or subs. Paws are pins which are inclined to the bit axis at different angles depending on the purpose. Trunnion bearings disposed various configurations forming cones support. Mounted on support cone conical shape. On cutters and the main body taken calibrating armature consisting of milled steel teeth or tungsten carbide cloves. Milling cutters are retained on trunnion rock bit against axial movement by means of locking devices, which are constructed as locking ball bearings collected through the holes in trunnions. The hole in the journal covers a special pin which sealed weld seam on the back paws.
