Every mechanic knows what a wrench is and how this tool works and helps make their job easier on site. However, for those who are starting in the field, it is worth knowing what a wrench is and having one handy on the job site. A wrench is a rather common tool that is utilized to provide a manual grip for the application of pressure and torque. This tool is used to turn nuts and bolts.
There are different types and styles of wrenches available in the market. The most common ones include box-end wrenches, open-end wrenches, adjustable wrenches, flex head wrenches, spanner wrenches, electric impact wrenches, and air impact wrenches.
At first glance, an impact wrench may look like an electric drill. However, they do not have a lot of functional similarities. An electric drill provides a consistent source of speed and power. On the other hand, an impact wrench provides a higher as well as more powerful torque at a lower speed compared to an electric drill.
The impact wrench is designed in a way that a hammer-like structure strikes against an anvil. This anvil is connected to a square driver located at the end of the wrench. Once the anvil is struck, this forces the socket of the wrench to apply power in incremental stages. The way power is applied ensures that the tool will not break the nut or bolt while providing the necessary amount of power to get the job done.
An air impact wrench or a pneumatic impact wrench has become the most preferred tool by automotive mechanics. This type of wrench makes use of the power of air to create a powerful force, which makes difficult tasks easy to manage. This tool requires a direct connection to an air source like an air compressor. Since this requires continuous connection to an adequate air supply, this is ideal to use for stationary locations.
An electric impact wrench, on the other hand, can either be cordless or wired. The corded version of this type of impact wrench is the same in terms of size and speed to that of an air impact wrench. This type offers more power compared to its cordless counterpart. However, this may be difficult to manage due to its electrical cable attachment.
A cordless electric impact tool is the ideal wrench to use when you are trying to work on hard to reach places. While this type of impact wrench is extremely handy, the downside of this type of wrench is that this does not offer the same amount of power compared to an air impact wrench. Nevertheless, if you need a simple wrench, this may be the ideal tool for you.
When it comes to price, electric impact wrenches tend to be pricier compared to air impact wrenches. Thus, it is worth to shop around and compare the different models and types of impact wrenches before purchasing one. This way, you can decide on the most appropriate tool that suits your needs and preferences.
