Features to be considered when looking for an air impact wrench | Buyers' Guide

- Wrench type. The power wrenches can be operated with an integrated impact mechanism and without it. Let's find out the main difference between such tools.

Due to the high torque and impulses of the hammer mechanism of a wrench, such tool features better efficiency and performance characteristics in comparison with the conventional power wrenches. Impact devices are quite powerful to handle rusted or jammed fasteners. Some extra powerful models are capable of undoing even large-sized bolts and nuts. Also, impact wrenches are widely used for the large-scale construction or repair projects. However, you should remember that the improved performance of such tools results into the higher cost.

The power wrenches are used simply to screw and unscrew bolts and nuts. That is, the fasteners are driven only by means of shaft rotation. These tools are less powerful with the lower torque. Wrenches without an impact mechanism hardly handle large screws or fail to undo a rusted nut. Thus, they are more suitable for small-sized screws or for getting more precision of a particular job. Lower prices for the impactless wrench will become an additional benefit for a customer who plans to use it for the light-duty or occasional jobs.

- Design peculiarities. Also all impact wrenches can be classified according to the design and configuration. In particular they are offered in in-line or “butterfly”, angle and pistol grip options. Angle and in-line wrenches are less common but still available. Angle models are designed with the motor in a handle. Usually, such wrenches are compact and lightweight tools which are especially useful at the tight spaces like an engine compartment of a car. Such devices are common helpers in auto service centers, assembling shops, and line productions.

The inline impact wrenches are equipped with a butterfly throttle which allows immediate changing of the direction from forward to reverse. Besides, due to the high torque, they can be successfully used for breaking out even the very old fasteners.

The pistol-grip design is the most common on the modern market. Such tools are capable of undoing jammed or rusted screws of various sizes. The weight is commonly heavy, thus the pistol wrenches are usually equipped with an additional handle. As a rule, this type of impact wrenches is highly demanded at various production facilities, auto service centers and tire shops.

- Max torque. This parameter means the highest torque a tool can reach, for instance, when loosening a rusted nut, etc. It is very important to differ the maximum torque of an impact wrench from the operating one. You can’t operate your tool to the maximum on the constant basis; otherwise it will result into an early wear of the components and the wrench itself. Thus, you should select a device depending on the sphere of its application. If the maximum torque matches your main daily-basis activities, it's better to choose more powerful option. In particular, the highest torque of the professional-grade wrenches may reach up to 2000 ft-lbs. and higher. But the optimal value would be in the range of 1200-1500 ft-lbs.

- Drive size. The air impact wrenches are offered with various drive sizes. Depending on your job conditions and the size of screws, you can choose from 1, 1 1/2, 1/2, ¾ and 3/8 range. But remember that the selected size should also match the rated torque of your wrench. Thus, the higher the torque is, the bigger screws the tool will handle. On the contrary, the smaller the drive size, the lower the torque will be.

- Speed ​​(RPM). This parameter can be mistakenly considered as the torque range which determines the power of an impact wrench. Of course, the rotation speed of a tool can also enhance its performance; however the RPM will mostly influence the operating speed. The heavy-duty professional-grade models can reach up to 9,000 RPMs. Thus, having picked up a powerful high-speed tool, you should always bear in mind that the thread of the small-sized fasteners can be stripped at the high speed ranges. And special precautions must be taken, accordingly.

- Design. Impact wrenches are made from steel, aluminum, or combination of the composite materials. The air impact wrenches with the steel or aluminum body are more resistant to a negligent use, dirt or collapse. Obviously, such models are heavier in comparison with the counterparts from the composite materials. For this purpose, many advanced models come with an additional handle for better stability and convenience for a user. Besides, the majority of these tools have the rubberized coating.

A composite built wrench is a combination of metal and plastic. Such body takes the advantages of both materials. Due to the latter the weight of a wrench is considerably lighter. Such tools feature an ergonomic non-slip handle, and a body which contributes to lower vibration in comparison with the metal alternatives. However, such models are more exposed to dirt and debris from the outside and are more sensitive.

- Shank length. The length of the wrench shank can be different depending on the purposes and conditions of its application. The elongated spindle allows handling deepened screws at the tight spaces. Commonly, the powerful air impact wrenches for the heavy-duty applications like servicing of trucks, etc., are equipped with a long spindle.

- Power setting. The powerful air impact wrenches are capable of generating more torque to deal with the large rusty or fused fasteners and bigger volumes. The possibility of speed setting allows control of the torque of a wrench. Thus, this function will be useful for tightening or loosening screws more safely. The number of speed settings depends on a particular model and its performance characteristics.

- Air compressor selection. Now, you are a happy owner of an air impact wrench which corresponds to all your requirements. Nevertheless, this is not the end of the picking-up story! It is the time to proceed with the selection of an air compressor. The latter should ensure the required operating pressure and an adequate consumption of the compressed air. The standard range of the operating pressure is in the range from 90 PSI to 95 PSI. Thus, the compressor which you are planning to use should be rated for 145 PSI max. In other words, it should be at least 1.5 times above the operating rates.

Air consumption is a very important parameter for a pneumatic impact wrench. Taking into consideration this value you may choose an appropriate tool for the compressor already available, or purchase a compressor for your air unit. An average air impact wrench would consume around 5 CFM. The latter is a rough estimation which will be influenced by the operating intensity and loads. If air consumption will not match the appropriate rating of your compressor, then you might have problems with lack of the air to properly operate your tool with the desired torque.

FAQ

What air compressor do I need for an impact wrench?

In order to ensure efficient and trouble-free operation of your air impact wrench, the source of the compressed air should be compatible with it. In particular, air consumption and operating pressure must be rated accordingly.

Ideally, the operating pressure of a compressor should be twice as high as the rating pressure of a tool. And the capacity of the compressor should be 20-30% higher than that of the tool. If these conditions are observed, your air wrench will be running flawlessly.

How to use air impact wrench?

The air supply system is a must for the purpose of starting and running of an air impact wrench. Also, you will need a hose to connect the tool with the air compressor before its starting. Besides, a water filter for the compressor and an oil cup to lubricate the internal moving parts of the wrench to prevent friction and an early wear will be crucial elements as well.

Assembling and presetting.

  1. First, you should connect the air wrench and the compressor with a hose and tighten it.
  2. Power the compressor and wait till it reaches the desired pressure level.
  3. Before running the air wrench, you should carry out a trial start in order to check its correct functioning. Push a trigger and check the rotation. Then release a trigger and select a desired speed. Also, try to change the rotation direction of the tool.
  4. Install a shank of an appropriate size and check its retainer, if available.

If all conditions are satisfied, you can proceed with the operation of your air impact wrench.

How to adjust torque on air impact wrench?

The adjustment of the torque is a crucial function for the modern impact wrenches. It would be absolutely wrong to use an impact wrench with the same torque for all standard sizes of the screws. It is necessary to observe the common procedures related to compliance of fastener size with the rated tightening force. For instance, smaller screws, bolts and nuts should be handled with lower torque; otherwise there is a high risk of their damage. Larger bolts could be tightened with the same wrench which has the higher power settings due to the fact that higher force is required.
