8" or 6 1/2" Sinter Type Matrix Water Well Drilling PDC Drill Bits
1. Specification
1). Tungsten carbide matrix PDC possesses high wear resistance and impact resistance.
2). Parabolic crown profile and maximise junk slot area can clean bie better,and prolong the bit working life.
3). Non-symmetry blade arrangement enhances drilling well balance.
4). Opetimization 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.
5). Meet strictly of API and ISO standard
6). High quality, reasonable price and best service
7). Good feedback of the clients
8). Delivery on time
9). Manufacturer of PDC bits and steel tooth tricone bits and TCI tricone bits
10). High wear resistance, high impact resistance and high penetration rate
Application:
1). Suit for drilling medium to medium-hard formations.
2). Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented .
3). Composite gage protection and low torque design improve rate of penetration .
4). CFD hydraulic balance design results in better bit cleaning and cutting removal .
5). Combined utilization of high performance PDC compacts significantly prolongs bit life
Advantage:
Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allows for higher flow rates with minimal increase in pump pressure.
Feature:
Diamonds are impregnated in the matrix behind the PDC cutters
Benefit:
Increased footage drilled in abrasive applications
