12 1/4 inch PDC bit M167
|Number of Blades||7|
|Primary Cutter Size||16mm|
|Gauge Length||3 Inch|
|Flow Rate (lps)||28~70|
Medium-hard to hard formations with low compressive strength , such as claystone,marl,lignite,sandstone,anhydrite,
The M1375 is a matrix body PDC bit.
Optimized Hydraulie design and enhanced
cleaing and cooling effects of the bits to
prevent bit from balling.
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 bits
The strength and ductility of steel give steel-bit bodies high resistance to impact loading. Steel bodies are considerably stronger than matrix bodies.A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.
