For diamond-impregnated bits ,only matrix-body construction can be used . Steel-body Advantage : High resistance to impact loading Considerably stronger than matrix bodies Easily be rebuilt a number of times Worn or damaged cutters can be replaced rather easily Particular advantage for operators in low-cost drilling environments ♦Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance. ♦ Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed. ♦ Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa ♦ Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life ♦ No repair life up to 8300M/pc ♦ The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed. ♦ The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth ♦ Speeds up to 30~40m/h ♦ Authoritative API standard and ISO certification, quality and service will be better ensured The main structrue features: --Tungsten carbide matrix PDC possesses high wear resistance and impact resistance. --Parabolic crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life. --Applying hydraulics balance design , 5 renewal nozzles and reasonable nozzles locating angle can gain ideal fluid field in well聽 bottom , fully clean and cool cutter , and prolong the cutter working life. --Non-symmetry blade arrangement enhances drilling well balance. --Optimization for cutter shape ,slant angle , cutter numbers prolong the cutter working life in combination with high quality PDC cutter, and improve ROP and drilling efficiency. --It can be used on rotary or down hole motor. --High HIS is recommended.
