Fishing Spears
A fishing spear is usually the first recovery tool employed when tools are broken off in the bore hole. The spear screws directly on the drill rods and will withstand light driving to aid in spearing the last tool. Fishing spears are easy to break loose if the drill tools cannot be recovered.

Heavy Duty Casing Retreiver
The casing retriever is attached to the drill rod and carefully lowered into the top portion of the lost section. Withdrawing the retriever causes the sliding jaws to wedge securely against the inner wall of the casing. The retriever is removed from the casing by pushing the assembly out the bottom end. If the retriever becomes stuck in the hole, the unit is designed to break off at the replaceable nose.
