USE:

Drill soft to hard rock, widely used in all kinds of drillings for prospecting, water and electricity building and construction industry of road, railway, bridge and building taking out core to examine stake, etc.

Features:

1. Available in all standard drilling sizes
2. Hardened alloy as raw material,it can serve in a long lifespan
3. Core lifters are divided into slotted and fluted .They have the advantages of good springness and

long life.
4. Our company produces all kinds of core lifters ,which have the merits of good springness and long

life. The core lifter pedestal experiences salt bath quenching which makes it good stability.

The drilling fluid circuit operates withinthe available annular areaprovided.More specifically, after

travelling through the drill rods, the fluid enters the core barrel.

There it is channelled between the inner and outer tubes, exiting via the throat of the diamond bit, and

back out between the outer tube and bore hole wall to the collar .

At the bit end of the inner tube, core lifter case adjustment and core lifter selection are of great

importance. The core lifter case needs to be placed close enough to the throat of the bit to allow for

efficient core breakage, butundesirable increase in fluid pressureand/or sample washing from the

drilling fluid.

By design, the tapered core lifter slides along the inside of the core lifter case, wedging and securing

itself onto the core during core recovery and breaking.
