Abstract
To remove a densely packed insulation sample from a coring bit, a sample removal tool is provided. The sample removal tool holds the coring bit in axial alignment with a plunger rod. The plunger rod moves axially toward the coring bit as a trigger mechanism is repeatedly actuated. Preferably, frictional plates encompass the plunger rod and force the plunger rod into the coring bit. The plunger rod contacts the sample within the coring bit and forces the sample out of the bit. After the sample is removed, the plunger rod is pulled back through the coring bit, and the coring bit is released from the sample removal tool.
