Introduction
The 3-wing stepped drag drill bit is an integrated structure cast from alloy steel, with a tungsten carbide cutting tip and gauge side to ensure a longer service life. It has 3 wings and 3 flushing holes. Compared to the 4-wing towed drill, the 3-wing stepped towed drill tends to drill faster, more fiercely, with shorter duration and poorer durability. The 3-wing stepped towed drill will generate greater cutting force than the herringbone shaped towed drill. The rotary table speed of the step resistance drill should be between 60 and 80 rpm, and the drill weight is light (WOB).
Features
Bits are economic tools for drilling soft tectonics and shallow depths. They are mainly designed for soft to medium strata, such as clay, loam, silt, and most soft to medium soils have some water. And it is also recommended to use stepped drag drills in mining, exploration, environment, water wells, geographic exchange, and other drilling wells.
Used in
Tri-cone bit is a decelerating bit. It is based on the fact that the speed of the cone is less than the speed of the bit. It is suitable for sidetracking of old wells and deepening of small boreholes under high speed and high drilling pressure.
