Buying Guide Image

Finding the Best Pneumatic Impact Wrenches for You

Air Compressor

The first thing you must evaluate to decide on the correct impact wrench is the capacity of the air compressor. It is important to ensure that the compressor delivers enough power for the impact wrench to function properly.

The way to determine if the compressor has the appropriate power for the impact wrench that you want to buy is to first know the flow rate (measured in cfm or cubic feet per minute, or liters per minute) and the minimum pressure (measured in psi, bars, kg/cm 2 or kPa) of the air that the impact wrench needs to function.

Most pneumatic tools require 90 psi (6.2 bar or 620 kPa) pressure, and impact wrenches are no exception. Too high pressures cause excessive wear and failure of the tool after a certain time. Conversely, tools that operate with too low an air pressure are often lacking when operating at full power.

For its part, the flow is a significant factor, because the compressor must be able to supply the air at a higher speed than that consumed by the impact wrench. Otherwise, you will lose torque capacity in the tool. In other words, for good performance, the compressor must exceed the air pressure and flow requirements of the impact wrench.

Anvil Size

Many fall into the error of thinking that the larger the anvil size, the better the performance of the impact wrench will be, but this is not necessarily the case. For example, would you use a 1-inch wrench to always loosen 10mm screws? Sure not.

Therefore, you must consider the size of the nuts, bolts, and screws that you will typically use and accordingly search for impact sockets of that size, as well as the anvil sizes that are compatible with those sockets.

Commercially available pneumatic impact wrenches for light to moderate use have three main anvil sizes: 1/4 inches, ½ inches, and 3/8 inches. The most powerful heavy duty and very heavy duty (e.g. removing wheel lug nuts from tractors, combines or trucks) have anvil sizes of 1/2 inches, ¾ inches, and 1 inch.

Power Capacity

You must keep in mind that the maximum torque is greater than the working torque. So, it is vital to know the suggested torque value for the service that you have to perform and add an extra amount for the difference between the working torque and the maximum torque. Generally, the type of service required a response to three variables:

  • Very heavy: automotive, naval, aeronautical, railway assembly plants, agricultural and construction equipment.
  • Heavy: the assembly of large machinery.
  • Normal: maintenance or repair work.

Frequently Asked Questions (FAQs)

1. What air impact wrench has the most torque?

Best overall air impact wrench runner-up Featuring 900 pound-feet maximum torque and 1,295 pound-feet loosening torque, Aircat advertises the 1150 as the most powerful 1/2-inch impact wrench in its class.

2. What is a good psi for an impact wrench?

90 PSI is the minimum required for most air impact wrench compressors to work correctly. You need an air compressor that has a higher shut-off pressure. Pressure loss in the line is one of the things that should be considered when shutting off a compressor at 100 PSI.

3. How much torque do I need for impact wrench?

Generally speaking, an impact driver with 1500–1800 in-lbs of torque puts more emphasis on higher RPM. It will do 95% of the work more quickly than a tool with more torque and slower speeds. Our rule of thumb is that, if you need to reach for a socket adapter, you're better off grabbing an impact wrench.

4. Is a pneumatic impact stronger than an electric?

Pneumatic wrenches are far more powerful than electric wrenches. Sure, nowadays, you can find cordless electric models that may come a bit close to the type of power air impact wrenches provide, but again, you'll have to rely on batteries.
