Bit Selection: Match Sand Grades for Water Well Drilling Rigs

Water well drilling rigs need precise bit-sand grade matching for efficiency. water well drilling rig

 

Fine sand (<0.5mm) works best with dense-tooth PDC bits. Small-spaced teeth cut sand bonds; high speed boosts drilling.

 

Medium sand (0.5-2mm) suits standard roller bits. Rolling crushes sand, balancing efficiency and wear.

 

Tips for water well drilling rig bit selection:

 

  1. Use reinforced roller bits for coarse sand (2-5mm). Thick bodies resist sand impacts.
  2. Choose impact-rotation bits for gravelly quicksand. Impact breaks gravel, rotation clears cuttings.
  3. Run sieve tests first. Map sand particle distribution to build a “grade-bit” guide.

 

This ensures optimal performance for water well drilling rigs in all sand types.
