A 1/2" drive pistol-grip air impact wrench. An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft ...
An electric impact driver typically delivers less torque and accepts smaller tool bits than an impact wrench. This makes the impact driver more suitable for driving smaller screws in (for example) construction work, while an impact wrench is preferred in situations requiring more torque to drive larger bolts and nuts (such as lug nuts).
By 1935, Milwaukee Electric Tool Corporation developed a lightweight 3/4" electric hammer drill. This power tool was designed to drill and sink anchors into concrete. This drill could also be converted into a standard 3/4" drill. Milwaukee also designed an easy-to-handle, single-horsepower sander/grinder that weighed only 15 pounds. [7]
The largest Battery torque wrench ever was invented and manufactured in Germany in 2013. It is capable of 31,000 Ft lbs of power with a 2.5 inch square drive output. Torque capabilities of battery torque wrenches range from 30 Nm, up to a maximum of 42.000 Nm (20 Ft. Lbs - 31.000 Ft. Lbs).
A square screw drive uses four-sided fastener heads which can be turned with an adjustable wrench, open-end wrench, or 8- or 12-point [67] sockets. Common in the 19th and early 20th centuries, when it was easier and cheaper to manufacture than most other drives, it is less common today (although still easy to find) because the external hex is ...
Crane with a pile driver 1 ⁄ 2 in (12.7 mm) drive pistol-grip air impact wrench. A nail is pounded with a series of impacts, each by a single hammer blow. These high velocity impacts overcome the static friction between the nail and the substrate.
On September 1, 2016, DeWalt debuted its FlexVolt hybrid voltage battery pack that can switch between series battery wiring providing 60 V (54 V nominal) and 2 Ah, or parallel wiring for 20 V (18 V nominal) and 6 Ah, depending on whether it is installed in a 60 V or 20 V tool, determined by communication between the tool and battery.

A spoke wrench that fits three common nipple sizes. A spoke wrench or spoke key is a small wrench or tool used to adjust the tension in the spokes of a tension-spoked wheel.A spoke wrench is sometimes called a nipple wrench, as it is the spoke nipple – not the spoke – that is turned in the process of changing the tension of a spoke.
