Power wrench

A power wrench is type of wrench that is powered by other means than human force. A typical power source is compressed air. There are two main types of power wrenches: impact wrenches and air ratchet wrenches or pneumatic ratchet wrenches.[1]

Air ratchet wrench

An air ratchet wrench is very similar to hand-powered ratchet wrenches in that it has the same square drive, but an air motor is attached to turn the socket drive. Pulling the trigger activates the motor which turns the socket drive. A switch is provided to change which direction the socket drive turns.[1]

This type of power wrench is designed more for speed and less for torque. If high levels of torque are desired an impact wrench should be used.

gollark: "Compare" how? You'd need to fuzzy-match them somehow to deal with differences in compression or whatever.
gollark: - post all of them on reddit and see if someone says one is a repost of another
gollark: Some very rough ideas for how to detect similar images:- remove blank space at top/bottom/sides and do the rest of these- run OCR over the text and check for matches- split image up into chunks, reduce the color space a lot, count how many times each color appears, check for similar chunks in other images- run edge detection on them, get locations of edges, fuzzy matching of those- ML-based object detection?- some sort of locality-sensitive hashing for image data
gollark: Probably, but I don't know what software or have any idea how it works.
gollark: Or look at how the repost detection bots do it.
