Among socket powered tools, impact wrenches have stood out. They are powered by electricity or compressed air and are commonly used by professionals. They work by spinning the hammer at a high speed before engaging the socket suddenly to deliver a sudden torque burst. This tool is available in different models including the electric, hydraulic and air units. One should therefore learn about the different models in order to make the right choice.
Before you choose a model, it is good to understand various requirements for this tool. First you have to consider the power source and also the socket size. The power source is mainly determined by the budget you have set for the acquisition and the types of tools you already have. The socket size on the other hand mainly depends on the type of work you are engaged in.
Among all the categories, the air models are the most popular because of various reasons. The first one is that they can help you handle a serious amount of auto work. They are also relatively cheap and offer good power. However, this model also requires a compressor. If you do not have a compressor, buying the right one will add more cost. This is why you should also consider the other models.
For occasional auto work in your home a garage the solution can be an electric impact wrench. This will not require additional acquisition and can handle your light work effectively. The best choice would be a cordless one since it offers you more freedom and is reasonably priced.
As indicated earlier, the socket size is important depending on the work you are engaged in. For most wrenches, the socket size ranges from a quarter inch to two inches. You can also get a larger size if your work demands so.
If you are working at home, a half inch socket size would be great and especially if you are working on a light commercial vehicle or an SUV. For large rims the two inch drive would be perfect. The other sizes are only necessary for industrial purposes.
Finally, you need to decide on the style for the wrench. The smallest wrenches are usually shaped like screwdrivers but they cannot deliver high torque levels. For the other models, especially the half inch, you have a pistol grip. The more advanced the model is, the better the grip and these include the T and D grips which provide a firmer hold. Having all this information should help you select the right impact wrenches for your tasks.
