PDC bit usage attention

PDC bit is very impressible for different stratum; the best drilling parameter depends on the stratum characteristic, and will be changed according to different stratum.

PDC bit is mainly used into soft ~ medium hard stratum drilling work, it will cause a lot of rock fragments during the drilling work. Therefore, flushing water is necessary for bit washing and cooling. It is also the one of important factors to effect drilling speed.
When PDC bit drill hard stratum, the working layer tooth will be consumed more easy (high drilling speed & pressure), in order to keep long service life, the lower drilling speed (80~120RPM) and lower pressure will be recommended
