A ratcheting threading tool, comprising,
- a ratcheting head, the ratchet head including a cylindrical rotary disc rotatably mounted within the ratcheting head arranged for ratcheting engagement relative to the ratcheting head, with the rotary disc and the ratcheting head coaxially aligned along a predetermined axle, and,
- the rotary disc including a central polygonal aperture directed through the rotary disc coaxially aligned relative to the predetermined axis, and,
- a first handle fixedly mounted to the ratcheting head, and,
- a threaded socket mounted to the ratcheting head longitudinally aligned with the first handle, and a second handle arranged for selective securement relative to the threaded socket, and,
- a die holder member, with the die holder member arranged for mounting within the polygonal aperture, and,
- a collet assembly, with the collet assembly arranged for mounting within the polygonal aperture, wherein the collet assembly is arranged for securement of a threading tap, and,
- the die holder member includes a die holder polygonal shank, and the die holder polygonal shank arranged for complementary reception within the polygonal aperture, and the die holder member further including a split collar mounted to the polygonal shank coaxially aligned therewith, with the split collar including a first flange and a second flange, with the first flange and second flange arranged in coextensive relationship relative to one another biased in a spaced relationship relative to one another projecting laterally beyond the die holder polygonal shank, and a threaded lock rod orthogonally directed through the first flange and the second flange for directing the first flange towards the second flange, with the split collar having a split collar bore directed therethrough, with the split collar bore further directed through the die holder polygonal shank, and the bore having a toothed interior bore wall, and a thread cutting die, wherein the thread cutting die includes a toothed exterior side wall arranged for complementary engagement with the toothed interior bore wall.
