001 Alloy Scraper Diamond Water Well Bit PDC Bit

Product Description

-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 specification:75#,90#,113#,133#,153#,171#,219#
2. Enhanced specification:75#,90#,113#,133#,153#,171#(Dual water ball),171#(Three water ball)
3. Special type specification:65#,153#(4 wing),3 wing(It can be directly connected with the drill pipe)Specifications are 32#,42#,50#,60#,76#,89#(Routine for 50#)
4. Composite sheet reinforced:There are mainly 1304,1308,1313,1613,1906,1908,Routine for1304,Enhanced1308 Specifications 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.
