Specifications of PDC drill bits

Application formation for PDC drill bits

Suitable for high comprehensive strength,with abrasive medium hard to hard formations,such as shale,limestone,anhydrite,sandstone,etc.

The characteristics of the three kinds of Water Well Drill Bits are as follows

(1) The welding tooth type drill bit has the advantages of fast drilling speed and low price. general drilling personnel.

(2) The whole sintering type bit can not drop teeth, the drilling speed is sharp, the efficiency is high, the price is reasonable: the drilling speed is fast. S high density steel bar, steel plate concrete construction site. Projects with tight schedule.

(3) The welding tooth type bit is durable and has a large number of holes, which reflects the characteristics of reasonable price, fast drilling speed and more drilling meters. Applicable crowd: professional drilling personnel.

Common Sense:

When drilling, the pressure should be reasonable, and it should not be too heavy or too light. If the drill bit cannot be drilled due to polishing, parallel grinding wheel or firebrick can be used to cut the cutter teeth
