-WHY CHOSE US-

 SPEEDMADEDRILL is a leader in the manufacture and development of many kinds of  bits in China. We provide the best quality PDC coring drill, DTH drill, Tri drill bits etc to the market, all types of non-coring or coring drill traces. Our drill bits are used for well drilling, mining and construction contractors. Our drill bit has been tested and verified by time, with wear resistance and fast drilling speed. Different drill bits can be customized according to different rock formations. The engineering time is greatly shortened, and the maximum performance is exerted in the operation during drilling. Our products are durable and reliable. Our products are the preferred drill bits for drilling engineers in many countries because of our precise design and efficient drilling during use.

 

	Speedmade TRICONE  ROCK BITS ADVANTAGE
*****	High speed floating bearing structure,metal face seal journal, which prolongs the life durability under the condition screw drilling.
*****	Efficient cutting tooth and optimized cutting structure to help rasing the bit ROP
*****	Cone body protection against excessive wear of rock debris and unbroken rock which  improve the life durability of rock bit in direction and horizontal wells
*****	Speedmade high speed motor bit is suitable for drilling with totary speed from 300 to 90 RPM, which is the ideal choice for directional well,horizontal well and horizontal mutilateral well drilling
