etc. This kind of core drill strictly complies with the
international standards.
The Wire-line core drilling tools can lift core from drill rods
without picking up coring system. During this process, picking up
coring system is not necessary. Core barrel assembly, overshot
assembly, drill rods, holding dog, hoisting plug, circle wrench are
all belong to drill tools. A complete set of wire-line drill tools
include: core barrel assembly, overshot assembly, drill rods,
holding dog, hoisting plug, drilling rods, inner tube, outer tube,
reaming shell, core bits, circle wrench, etc. It has some
advantages such as high penetration rate, high core recovery ratio,
long bit life and lower labour intensity, the advantages can get
more clear with the increasing of drilling hole depth.

shortening the release time
5. Pump-in overshot features a ball valve indicator which alerts
the operator of positive latching onto the core barrel's back end
