Mining Rotary Tricone Drill Bit , Tci Tricone Bit IADC Code 542 642 712 for Hard Rocks Drilling
IADC code 537/517/617/637 tricone drill bit 6 1/2"
ROSCHEN Tricone bit advantages :
There is a Tri Cone suitable for any rock formation
Tricone bit is versatile and can handle changing formations
Tri Cones are reasonably priced, long lasting and have an efficient drilling rate
The tricone bit lift time is according to the drilling rig and formation.
Very soft with low compressive strength and high drill ability rock formation, like shale, clay, conglomerate and sandstone, etc.
O ring seal is made of the more wear resistant and high saturated buna-N with the increased seal section and precisely designed scaling flange in the cone sealing area has increased the reliability of the seal.
High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts. For steel booth bit, the tooth surface is hard faced with new type of wear resistant material and thus has extended working life of the cutting structure while still maintaining high ROP.
Journal bearing, hard faced bearing surface, inner hole of cone is silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
