The Advantages to Use Tricone BitsThan Other Kinds of Rock Bits

1)  There is a tricone suitable for any rock formation

2)  Tricone bits are versatile and can handle changing formations

3)  Tri cones Are reasonably priced with long life and good rate of drilling

 

 Tricone Bits usage Instruction

 •  Tricone bit transportation

         As the small volume of tricone bit and heavy weight,safety should be noticed during transportation.The package

         is carton or wooden case.Waterproof and damp proof should  be noticed during transportation.

 •  Tricone bit storage

          There is rubber piece and lubricating grease in tricone bit,So it can not be stored in the open air.and be damp                   proof. The temperature should be 0-40 centigrade degrees. No welding,heating and other processing is permitted               on bit.

 •  Tricone bit validity

          The roller bit should be utilized within four years after resembling Type selection of tricone bit

          Appropriate bit should be choosen according to drilling formation lithology and reference

          on the conjoint well.

 

 NOTICE: When shrink hole and long section is needed.it’s avoiding to work
