Abstract

Machine thread cleaning tool which is quick and simple and does not recut threads and therefore does not require replacing connecting components, but merely removes corrosion and dirt. The tool, or chaser, does not require that components extending outward from the machine casing be removed and the chasing can be accomplished using a basic spanner wrench. The tool comprises a disk with bores through the center thickness and parallel grooves running along the circumference of the disk and across the entire thickness.
