Impact air wrenches which are the best? What impact air wrench should you buy? These are all questions that we may face when starting to shop around for impact air wrenches and power tools. For many home mechanics and weekend repairs on your cars and vehicles a modest priced impact air wrench will usually suffice.

The impact air wrenches come in sizes from 1/4 inch up to 1 inch drive.
The smaller 1/4 impact air wrench is designed for very precise torquing purposes. Whereas the 1 inch super duty impact air wrench is for industrial use.

For most home mechanics and garage workshops the 3/8 and 1/2 inch drive pneumatic impact wrench will be suitable. These impact wrenches will easily break loose lug nuts and tough highly torqued engine bolts.

If you will be using your pneumatic wrench as a professional mechanic you might consider purchasing a 3/4 inch drive impact air wrench. These air impact wrenches are designed for heavy use and will not break as easily as a 1/2 inch drive model.

For working on heavy machinery and industrial use, we suggest going right to the super heavy duty impact wrenches that have a 1 inch drive. You will need the extra torque that only these impact wrenches can provide. Many of the bolts and nuts that are on industrial machinery are torqued to such high foot pounds that a regular 3/4 inch drive impact air wrench just won’t break the bolt free. Worse off is that you will never get the bolt back on with the correct torque applied. Having improperly torqued bolts and nuts can lead to physical harm or expensive damage to machinery.

Other things to consider before purchasing your pneumatic impact wrench are, do you have the correct air compressor to power your air wrench? Remember the larger the power tool the larger the air compressor you will need. Another thing to think about is the sockets you will be using. Regular sockets for hand tools will not work, they break easily so you might need to invest in impact wrench sockets. These sockets are specifically designed for use with impact wrenches and are designed for the punishment that a pneumatic impact wrench will put them through.

For different manufacturers we rate Chicago Pneumatic, Porter Cable Ingersoll-Rand and Sk Hand Tools as the best manufacturers of pneumatic hand tools. They build their power tools to the highest standards, with great performance. These impact wrenches are built to last under heavy usage and they always back them up with great warranties.

One last thing to consider that many ask is could buying a cordless impact wrench work just as well as a air impact wrench. From me personal experience the cordless impact wrench is great for portability when you are away from your air compressor. But the impact air wrench is far superior in terms of torque, longer life and it has less moving parts to break and wear.
