Things that are needed to make impact wrench more powerful

  • An impact wrench
  • A powerful drill bit
  • A drill press
  • High-quality lubricant
  • A torque multiplier

How to make impact wrench more powerful – step by step guide

The impact wrench is a handy and powerful tool that can remove mostly stubborn fasteners easily. But sometimes, you may feel less power with these tools while working. So, to increase power, follow this step by step guide-

  • Using the powerful drill bit, make a hole in the center of the anvil on your impact wrench.
  • Be careful; it can damage any of the internal parts of your wrench! You can use a drill press to keep the drill bit steady as you work. Otherwise, take your time and be extra careful.
  • Once you’ve made the hole, apply some lubricant to the inside of it. That will help you to prevent wear and tear on your impact wrench.
  • Next, take your torque multiplier and attach it to the anvil of your wrench.
  • Make sure that the multiplier is secured adequately before using your wrench! If it isn’t, you could damage both the multiplier and your wrench.

That’s all there is to it! Following these steps can make your impact wrench more powerful than ever before. Give it a try today and see how much difference it makes. We think you’ll be impressed!

There are also other ways to increase your impact wrench power and performance

Power is the most important thing when it comes to removing stubborn nuts and bolts. You may have a less powerful impact wrench and want to increase the power. Learn how to make your air impact wrench more powerful with these simple tips-

Replace the standard air compressor with a high-pressure one

How to make an air impact wrench more powerful? An air impact can quickly remove stubborn bolts and nuts. However, the standard air compressor that is used to power these tools can be lacking in terms of both power and pressure. As a result, many mechanics use a higher-pressure air compressor to get the most out of their impact wrenches.

It will significantly impact the tool’s overall performance. With a higher-pressure air compressor, the impact wrench will have more power to loosen even the most stubborn fasteners.

In addition, the higher pressure will help to prevent the tool from stalling during extended use. As a result, replacing the standard air compressor with a high-pressure one can be an excellent way to gain more power and performance out of an air impact wrench.

Use a longer socket extension

Sometimes it is necessary to increase the impact wrench torque, or rotational force, in order to loosen a particularly stubborn bolt. The simplest way to do this is to use a long socket extension. By lengthening the distance between the wrench and the socket, you can increase the amount of torque that is applied to the bolt.

In addition, using a longer extension will help to prevent damage to the surrounding area, as it will distribute the force over a larger surface area. As a result, using a long socket extension effectively increases the torque on an impact wrench.

Use penetrating oil to loosen tight bolts before using the impact wrench

When working with a stuck bolt, it’s essential to use the right tools and techniques to loosen it. Otherwise, you could damage the bolt or the surrounding area. One tool that can be helpful in this situation is penetrating oil. This oil helps lubricate and penetrate rust and other build-ups that can cause bolts to become stuck.

Before using an impact wrench, apply penetrating oil to the bolt and let it sit for a few minutes. This will help to loosen the bolt so that you can remove it more easily. Be sure to read the instructions on the penetrating oil before use.

Clean the impact wrench regularly

Over time, the internal components of the wrench can become filled with dirt and debris, which can reduce its power and performance. For best results, it is crucial to clean the impact wrench regularly. Start by removing the air filter and cleaning it with soap and water.

Next, use a brush to clean the housing interior properly. Be sure to pay particular lookout to the area around the hammer mechanism. Finally, if there are any remaining dirt and debris, use compressed air to blow them out. These simple steps can help you to ensure that your impact wrench will continue to operate at peak performance.

Add a washer to the end of the impact wrench’s shaft

Adding a washer to the end of the impact wrench’s shaft can provide more power for specific applications. The washer acts as a weight, and when the wrench is operated, the added mass creates a flywheel effect that can provide more torque. This can be especially useful when breaking loose stubborn bolts or nuts.

In addition, the increased mass can help to dampen vibrations, resulting in a smoother operation. However, this modification will also increase the overall weight of the tool, so it may not be suitable for all users. With careful consideration, adding a washer to an impact wrench can be a simple and effective way to boost its power.

Install an aftermarket piston and spring kit

If you’re looking to increase the output of your impact wrench, one option is to install an aftermarket piston and spring kit. These kits often include a higher-output air compressor, which can deliver more air to the impact wrench’s motor.

In addition, they also include a stronger spring, which can help to increase the torque output. When purchasing a kit, ensure to select one that is compatible with your specific model of the impact wrench. By following this simple modification, you can significantly increase the power and performance of your impact wrench.

Replace the non-ratcheting handle with a ratcheting one

The non-ratcheting handle that is typically used can limit the amount of torque that can be applied to the bolt. As a result, the bolt may not be loosened or tightened as much as desired. To increase the power of the impact wrench, you can replace the non-ratcheting handle with a ratcheting one. This handle will help you to apply more torque, making it easier to loosen or tighten the bolt.

In addition, the ratcheting handle will also make it easier to control the amount of torque that is applied, preventing damage to the bolt or surrounding area.

Why is my air impact wrench weak?

One possible reason your air impact wrench is weak is that the rotor or fan assembly might be damaged. If the damage is extreme, it could cause a loss of compressor output power, making the tool less effective.

The other reason is that the air compressor is not providing enough pressure. The recommended pressure for most impact wrenches is 90-120 PSI. If the compressor cannot offer this pressure level, the tool will not work as effectively.

Finally, it is also possible that the air hose is blocked or restricted somehow. This would cause a loss of airflow and prevent the tool from working properly.

If you have checked all things and the problem persists, then it is better to consult a professional for further diagnosis and advice.

How powerful of an impact wrench do I need?

Impact wrenches are available in a wide range of sizes, and the amount of torque they produce can vary significantly. Generally, the larger the wrench, the more powerful it will be.

However, other aspects should be regarded when choosing an impact wrench. For example, how often will you be using the wrench? A smaller and less powerful model may be sufficient if you only need it for occasional use.

However, a larger and more powerful model may be better if you use the wrench regularly. Eventually, the easiest way to determine how much power is needed for you is to experiment with different models and see what works best for your specific needs.


Impact wrenches are a powerful tool, but they can be even more powerful with the proper modifications. We hope this article will help you learn how to make an impact wrench more powerful and give you some ideas on what modifications might work best for your needs.
