Product details:
MRS concentric wave slider bit casing drilling system is made up of guide device and reamer bit which adopted graphic design to enhance penetration rate.
Expanding principle as below:
Guide device calms down pressure, open expanding wings in clockwise and shut down expanding wings in anticlockwise. The concentric slider bit casing drilling system is used for loose rock and can greatly increase the penetration rate. This concentric casing drilling bit is suitable for 219-813 tube in diameter.

Product advantage:
