Overview
Irwin 9739 is a single threading tool, pack of one, from Irwin's tool line, built with a blend material body and a brushed finish. At 0.96 ounces it is a compact, hand-held piece meant to cut or clean up threads rather than a bulky bench tool.
The category label on this listing is threadings, which lines up with the title, but no size or thread pitch appears in the attributes. Buyers who need a specific thread size should confirm it before ordering.

Who it's for

Performance notes
Threading tools like this work by cutting or cleaning a screw thread as it is turned into the material, and how well that goes depends heavily on matching the tool to the exact pitch and diameter of the target thread, information this listing does not spell out.
