Drag bits features: 1, A solid one piece heat treated, 4140 alloy steel body for bit strength & durability; 2, CNC threaded machining for proper installation &use; 3, Forgings are milled to better seat the carbide inserts. 4, Select tungsten carbide inserts 5.5mm thick are standard. 5, Relief is hand ground behind carbide inserts for maximum performance. 3 wings step drag bits are one piece construction of alloy steel cast with tungsten carbide cutting tips and gauge sides to ensure longer life. It has 3 wings and 3 flushing holes. Compared with 4 wings, 3 wings step drag bits tend to drill faster and aggressive, whereas, are shorter lasting and less durable. 3 wings step style drag bits will produce larger cuttings force than chevron style drag bit. Rotary table speed of step drag bits should be between 60 and 80 rpm with light weight on bit (WOB). 3 wings step drag bits are economical tools when drilling softer geological formations and shallower depths,they are primarilydesigned for soft tomedium formations, such as Clay, Loam, Silt , Mostsoft-to-medium soilsthat have some moisture, etc. And also step drag bits are recommended for drilling in Mining, Exploration, Environmental, Water well, Geo Exchange, etc.

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.
