BWL-NWL-HWL-PWL horizontal drilling Overshot

One typical problem when drilling with wire line, is to make the inner and/or Overshot reach their site of drilling on holes whose angle is approaching to the horizontal.

With this in mind, TECSO, SA has designed an effective Overshot for holes whose inclination is nearly horizontal, making easy much of this work where conventional Overshots are unable to fulfill their missions successfully.

This set allows, by water pressure, that the Overshot push the inner tube to its working position or remove it to the mouth of the hole.

These Overshots are not suitable for conducting drilling upward.
