BWL NWL HWL PWL CORE CATCHER DRILLING BASKET CORE LIFTER, CORE
SPRING
Core Lifter, core lifter case are components of a whole set of core
barrel.
Fluted Lifters
Ideal for use in broken formations, however they can be used in
other formations as well.
Slotted Lifters
Ideal for use in competent formations, however they can be used in
other formations as well
Finger/Basket Lifters
Recommended for sample recovery in fragile, unconsolidated
formations, these core lifters are typically used in conjunction
with face discharge bits.

Wire-line core drilling tools can lift core from drill rods without
picking up coring system. A complete set of wire-line drill tools
include: Core barrel assembly, overshot assembly, drill rods,
holding dog, hoisting plug, circle wrench etc. It has some
advantages such as high penetration rate, high penetration rate,
high core recovery ratio, long bit life and lower labour intensity.
The advantages can get more clear with the increasing of drill hole
depth.
