3 3/4 Air Flush Step Drag Bit - Factory Direct for Water Wells

Step Type These step type Drag bits are typically used in very soft or alluvial formations such as unconsolidated sands, clays, and can be used for scraping liners in workover applications, etc. However, due to the expense of tripping in and out of the hole, the lower cost of these non moving part drag bits versus roller cones, have a tendency to get pushed to the limit and often impress beyond its intended design. Unless requested otherwise, drag bits come standard with regular API connections and are center circulation (low pressure/high volume) bits. Drag bits are used in multiple industries such as oil, gas, and water well. We house a generous supply in multiple sizes and can fabricate any requested size, number of blades, etc.

DRAG BIT
Applications	Drag bit is a comprehensive dilling bit, mainly used for water wells, mining, geothermal, environmental and exploration dilling. It is suitable for dilling in soft and soft-medium formations with fast penetration rate and high efficiency, and special for the large diameter holes' dilling.

4 1/2 Inch Water Well Roller Cone Bit 114mm Steel Tooth Tricone Bit The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit. 1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate the upward flow of drilling cuttings and improve ROP. 2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability. 3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit. 4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.
