The automatic tap wrench is a versatile hand tool used for threading in metal or other materials. It is especially useful in confined spaces where a traditional tap wrench may be too large for effective operation.

Its main features are:

1. Compact Size: The wrench is relatively small in size, allowing work in areas where access is limited.

2. Ratchet Mechanism: It has a ratchet mechanism that allows the collet to rotate both clockwise and counterclockwise without the need to remove and reposition the wrench.

3. Clamping Adjustment: The wrench features an adjustable clamping mechanism to firmly hold collets of various sizes. This flexibility allows adaptation to different collet diameters.

5. Durable Construction: They are usually made from durable materials such as steel or alloy, ensuring strength and longevity during regular use.
