A portable machine for testing protective coatings which have been applied to pipes or the like comprising a portable frame adapted to be hand-held by testing personnel. A pair of elongated arms extend from the portable frame and have pipe shoes on one end thereof adapted to embrace the pipe so that the portable frame will be maintained at a predetermined distance from the pipe during the testing operation. A cutting blade is provided for severing the protective coating from the pipe and has an elongated flexible member connected thereto. A power assembly is secured to the frame and is operatively connected to the elongated flexible member to cause the elongated flexible member and the cutting blade to be moved towards the support to sever the protective coating from the pipe. A force read-out device is connected to the power assembly for indicating the amount of force required to sever the protective coating from the pipe.
