Goldman PDC DRILL BITS :
Matrix-body			Advantage  : Matrix body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail . 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: ***0MPa;  Rm: ***0 MPa
			Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life No repair life up to ***0M/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 *0~*0m/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 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.
