Ratchet tap wrench with automatic reversing clutch.

[Mook]

This tap wrench is designed to remain locked during normal operation, ensuring a positive drive. The ratchet is always readily available. However, many tapping situations benefit from a ratcheting function to make the process faster and easier.


Conventional one-way clutches have a major limitation — they prevent reversing the tap for chip breaking or removal. To overcome this, I developed a mechanism where the clutch engages automatically with downward handle pressure.


When reversal is needed, simply reduce the applied pressure. The clutch disengages instantly, allowing the tap to move in the opposite direction while remaining locked and concentric.


The result is a tap wrench that’s intuitive, efficient, and far more versatile than traditional ratchet designs.
