Steel Teeth Rubber Sealed Roller Rock Drill Tricone Rock Bit for Borehole Drilling
Steel Teeth Tricone Rock Bit is to directly mill the teeth on the cone cone. The teeth of the steel teeth are wedge-shaped, and the working surface and the back cone surface of the teeth are welded with materials.
Structural features
Steel Teeth Tricone Rock Bit has tungsten carbide butt-welded tooth surfaces, and the bearing system can accommodate higher rotational speeds. Drilling with Steel Teeth Tricone Rock Bit in suitable formation, high mechanical speed and long life. This drill bit is suitable for soft stratum, soft to medium hardness stratum, and is widely used in oil field, mine, geological survey, hydrological exploration, engineering piling, geothermal development, water well and other drilling fields.
Our company uses alloy sand to harden the palm back and tooth surface, which greatly increases the service life of the drill bit;
We optimized the number of tooth rows, the number of teeth, the exposed tooth height and the tooth profile, which fully exerted the cutting ability and cutting speed of the drill.
