-Product Advantages -Product Introduction: PDC non
coring drill bit is mainly used for water injection and drainage in
coal mine geology, rotary drilling for underground gas drainage in
coal mine and drilling for anchor net support in coal mine. Its
service life is 10 to 30 times longer than that of a normal carbide
drill. Different structure of the drill body welding different
positions of the composite pieces, so that the functional
properties of the bit is also different.So there are many different
types of PDC non coring drill bits on the market.PDC non coring
drill bit is highly adaptable to drilling in complex rock
formations, with good stability and hardness, strong wear
resistance, blade strength and impact resistance, high drilling
efficiency. The PDC non coring drill bit is a super-hard geological
diamond that can be directly connected to the drill pipe.Speedmade
Industries Co., Ltd. 's PDC non coring drill bit not only has the
above advantages, but also has high Drilling verticality.1. General

are75#,91#,110#,130#,150#,170#.In general, conventional 1304 is the
most common, and the dosage is also the largest. According to the
formation conditions, it can be matched with the geological
sheet/petroleum sheet to achieve reasonable use.Applicable stratum:
clay stratum, sand stratum, gravel stratum and weathered
stratum.-PRODUCT BRIEF-Strata Grading InstructionsGrade 1 loose
