Pneumatic Torque Wrenches Vs. Impact Guns: Comparing the Differences
When it comes to bolting and fastening, having the right tool is essential. Two of the most common tools used for these applications are pneumatic torque wrenches and impact guns.
Both have their own advantages and disadvantages that should be considered when making a decision about which to use.
Overview of the Differences between Pneumatic Torque Wrenches and Impact Guns
While both of these tools are effective in their own right, they operate differently and have their own unique advantages.
Pneumatic torque wrenches use air pressure with air mote and gearbox to tighten bolts accurately and with precision. They are ideal for applications that require strict torque specifications, such as in the automotive, oil, gas & aerospace industries.
Impact guns, on the other hand, use a high level of torque to quickly tighten or loosen bolts using a hammering mechanism to achieve the load. They are best suited for heavy-duty applications where speed and power are the most important factors and accuracy is not a requirement.
A professional understanding of the differences between the two tools can help you identify the right tool for the task, ensuring timely and accurate work.
Advantages of Using a Pneumatic Torque Wrench
Compressed air powers the air motor which drives a precision gearbox to achieve torque typically within an accuracy range of +/- 5% when the tool has the proper air supply provided. The result is maintained accuracy and uniform tightening, which is essential for ensuring equipment and machinery are operating at optimal levels.
Additionally, pneumatic torque wrenches are highly durable, with the ability to withstand harsh working conditions without breaking down. They also allow for ease and speed when it comes to tightening bolts, reducing the risk of operator fatigue.
All of these advantages make the pneumatic torque wrench a highly desirable tool for any professional.
Disadvantages of Using a Pneumatic Torque Wrench
One disadvantage is that they are limited in their usable range, as the wrench needs to be connected to an air compressor and have the right amount of pressure to provide the correct torque for the job. If the pressure is not correct, then it may not provide enough torque or could cause damage to your components.
Additionally, they require maintenance and upkeep in order to function properly. The air hoses and bolting steel connections must be regularly inspected, tightened, and replaced when necessary, or else the wrench won’t work properly.
Advantages of Using an Impact Gun
When it comes to machinery maintenance, an impact gun is an essential tool that can save time and effort. They apply a high amount of torque to stubborn bolts or nuts, enabling them to loosen quickly and easily.
An impact gun also has a unique design that allows it to work in harsh conditions and perform under continuous workload. This is a great tool to either increase the speed of loosening nuts or to provide pre-load to snug-fit certain applications as long as the application can handle the hammering force being applied.
Disadvantages of Using an Impact Gun
One major disadvantage of using an impact gun is the increased noise level. The loud sound produced by the impact of the gun can be very disruptive and requires hearing protection to always be worn when in operation.
A major disadvantage is the common use of impact guns is that you have no way to know what torque you have applied. In many applications, the use of an impact wrench can be the leading factor to bolt failure/fatigue which prevents proper clamp load from being achieved.
Considerations When Choosing Between the Two Tools
When it comes to selecting between two tools, there are several factors that you should consider before making your final choice:
- It is important to assess the specific needs and requirements of your task or project to determine which tool meets those needs most effectively.
- Do you need a higher torque output than the impact wrench can provide?
- Is an accurate torque required for final assembly?
- The usability and functionality of each tool should be evaluated to determine which one is the most user-friendly and efficient for your job.
- The size and weight of each tool should be assessed to determine which one is the most portable and convenient for you.
By taking these considerations into account, you can make an informed and confident decision when choosing between the two tools.
