The plug tap design makes this tool ideal for through-hole threading and general-purpose applications where complete thread depth to the bottom of a blind hole is not required. The straight flute configuration provides excellent chip evacuation, making it well-suited for tough threading work, repair operations, and re-threading applications where high accuracy is not critical. This tap is designed for manual operation with a tap wrench and works effectively in a wide range of materials.
