 |
Basical Specification | |
Size of bit | 4 1/2’’ |
Number of Blades | 5 |
Primary Cutter Size | 19mm |
Nozzle Qty. | 4NZ |
Thread Connection | 31/2 REG |
Operating Parameters | |
RPM (r/min) | 60~300 |
WOB(KN) | 10~100 |
Application | Medium-hard to hard formations with low compressive strength, such as hard shale, limestone, sand-stone, dolomite, hard gypsum, marble, etc. |
The material of the bit adopts high quality steel and wear-resistance material with high performance is built-up welded on the surface of baldes to prevent matrix mqaterial form eroding.
Bit body is made from an integrated alloy forging and finished by advanced CNC machining center.
Deep and wide junk slots ensure bit cleaning and cooling of drilling fluid ,which benefits fast drilling and anti-balling.
Adopts high performance PDC cutters ,increases the ability to drill through hard stringers and provides longer service life.
PDC cutters of different features are selected and bit profile design is optimized to suit differents when drilling applications in different formations to satisfy different requirements when drilling soft to medium hard formations.
According to the requirements of customers,desigh and produce different bits.
