Basical Specification | |
Size of bit | 8 1/2’’ |
Number of Blades | 3 |
Primary Cutter Size | 16mm |
Nozzle Qty. | 3NZ |
Thread Connection | 4 1/2 REG |
Operating Parameters | |
RPM (r/min) | 80~800 |
WOB(KN) | 30~120 |
Application | soft and medium soft layer,high abrasive formation |
Bit characteristics:suitable for soft and medium soft layer,high abrasive formation.
Bit performance:blade less,chip space is large ,and the use of good abrasion resistance,strong anti impact properties of high quality pdc films,is conducive to the
Three-dimensional rotating spiral blade runner injection,fast cutting exhaust,improve the service life of drill bits.Using swirl channel change bottom flow field,avoid duplication of cuttings,greatly improve the drilling speed.
