Buyer’s Guide to Air Impact Wrenches
Choose a wrench which has sufficient power based on your needs.If you need an air impact wrench for your home or DIY tasks, you can consider powers of around 300-500 ft.lbs. But if you want a wrench more for a workshop setup removing bigger log nuts and bolts, it is best you take an air impact wrench having power more than 700-800 ft.lbs.
Compatible Air Compressor
Carefully consider the capacity of the air compressor you have before choosing the compatible air impact wrench. It is suggested that you have a air compressor with at least twice the average air flow required by the air impact wrench. So if you choose an air impact wrench having an average air consumption of 4 CFM, it will run best with a compressor having greater than 7-8 CFM. Most wrenches mentioned in the list work best at an air pressure of around 90 psi, so keep that in mind as well.
If you have a very high power air impact wrench you may end up wringing a small bolt if you use all the power on it. So using a speed based on your power requirements can help you. Variable speed air impact wrenches come to your rescue in such a senario
Most basic air impact wrenches can be easily serviced by you. However if you choose a complex tool you may have to get it oiled by an expert which can cost you some bucks.
Choose a light weight model which will cause less stress on your wrist on extended usage.
Sound levels is something you would to consider if you are a professional. Air impact wrenches can create a lot of sound. You can always choose a sound reduction version for the tool if you are worried about the sound levels in your workspace.
Keep in mind the warranty conditions while you buy one from amazon.com
