The patent below was for RIDGID's Core Barrel Inner Tube Wrench. It was developed for the application of gripping thin wall tube of specific (high tolerance) sizes. For the core drilling application that the tube is used for, it was necessary for it to remain perfectly cylindrical as well as to minimize any sort of marring to the exterior surface. The wrench and it's replaceable inserts were designed with these considerations in mind. The inserts are coated with a proprietary process that minimizes any sort of damage to the core barrel tube.
