Since the first PDC cutters were introduced in the 1970s, tremendous technological advances have been made. The earliest PDC technique is used in oil drilling, until 1997, the first PDC mining bit(that’s small one) was produced.The success of this bit led to the founding of the Zuanlong drilling machine company. These small diameter PDC bits are popular in the country which rich in coal resources .

PDC bit’s penetration rates are much faster than that of other types of bit, which reduces your overall drilling time and operating costs. They also work in a wide array of formations, both hard and soft, and they are very effective in oil based muds. A major factor in drill bit selection is the type of formation to be drilled. The effectiveness of a drill bit varies by formation type. There are three types of formations: A soft formation includes unconsolidated sands, clays, soft limestones, red beds and shale. Medium formations include calcites, dolomites, limestones, and hard shale. Hard formations include hard shale, calcites, mudstones, cherty lime stones and hard and abrasive formations.
