Design character:

■Straight blade and short gauge: When pumpingpressure is low abrasive drilling mud can be dischargedquickly to avoid bit balling and losing efficacy of bit.

■Adopting CFD emulational technology to calculate to optimize PDC bit, then reduce possibility of heavy breaking and wearing of bit.

■Special design of back-rake angles will decrease torque on bit, increase bit aggressiveness, improve efficiency of ROP.

■Dual-row cutters.The back row cutters help to cut rocks, to protect matrix, to prolong lifetime and to deduct cost of PDC bit.
