A special impact wrench is a pneumatic or air-powered power tool that is used for loosening and tightening bolts and nuts. It works by sending a high-pressure air supply to the hammering mechanism in the motor which then produces strong and quick concussive blows which cause the nut or bolt to move.
There are many different types of impact wrenches that can be used for a variety of jobs. These include air, electric and hydraulic impact wrenches. They can be used in a wide range of applications including repair shops, assembly lines, heavy equipment manufacturing etc.
These wrenches are usually made from metal and a hardened impact socket is also commonly used to prevent it from cracking or exploding when it is being used. These tools are especially useful for working on cars, small engines and lawn mowers where it is necessary to get the lug nuts or other bolts very securely locked so that they do not come loose while driving or when the engine vibrates.
They are also a good choice for working on vehicles that have a lot of weight to them such as lawn mowers, snow blowers, motorcycles and other vehicles. These tools can be used to remove the lug nuts and other bolts from a car, so that it can be removed.
Some of the most popular impacts are air powered, while others use battery power and they are available in a range of sizes. Some are very large, producing thousands of foot-pounds of torque.
An air-powered impact wrench has an advantage over other types of impact tools because it is portable and can be operated in a variety of locations with ease. They also offer more torque than the electric and battery-powered models.
Besides being lightweight and easy to operate, air-powered impact wrenches are also very durable. They have high duty cycle ratings, meaning they can run for long periods without needing a recharge.
They are also easier to repair and maintain than their electric and battery-powered counterparts. They are also a lot cheaper.
If you are planning on buying an air-powered impact wrench, it is important to decide how many hours you plan to work with the tool and what the maximum torque you need for the job at hand is. This will help you choose a model that is right for your needs.
You should also consider the size of the wrench and how long it will last with proper care. If you are planning on using the tool for a while, it is a good idea to find one that has an extended warranty.
Lastly, the battery life of an impact wrench is also something to consider. You should look for a model that has a high capacity lithium-ion battery, which can be recharged more easily than older batteries.
When it comes to choosing the best impact wrench, make sure you shop around and check out the reviews from other users. You can read reviews from a variety of sources, including sites like Amazon. It is also a good idea to ask your local hardware store for their recommendations.
