Overshots

With Kobald Mining Services you are sure to work in safe environment.  Kobald’s overshot (pdf to be insert) allows the driller to recover the inner tube safely. No need to remember to stop and lock the inner tube assembly in place, gravity automatically does it for you! Available in both standard or rolling styles.

As soon as you start to raise the overshot the weight of the head pulls the lifting dogs into the locked position. The head remains “locked in” until the weight is removed and you manually compress the lifting dogs to release.

 Option 1 : Down the Hole                                       Option 2 : Top of the Drill String
