What is IPM on Impact Wrench – Machineriespoint

An impact wrench is a hand tool that uses compressed air, or an electric motor, to create a rotational force. This force is used to turn bolts and nuts, making it easier to tighten them.

IPM is a system that helps optimize an impact wrench’s power output. It does this by controlling the speed and torque of the tool automatically, depending on the task at hand.

When looking for an impact wrench, it’s essential to consider the IPM rating. IPM is the measure of how many times the tool can deliver its maximum torque per minute.

So, let’s look at what IPM is and how it works.? Read on to find out!

What is impact per minute (IPM) on an impact wrench, and why is it important?

IPM stands for “impacts per minute.” It’s a measure of how fast an impact wrench can deliver its blows, and it’s important because the faster the impact, the more likely it is that the bolt will loosen. IPM also measures how much work the impact wrench can do in a given time.

Most impact wrenches can provide between 1000 to 3200 impact per minute. A higher IPM rating means that the impact wrench can produce more torque faster and can do more work in less time. This makes it ideal for heavier-duty tasks.

For example, if you’re trying to remove a stubborn bolt, you’ll want an impact wrench with a high IPM so that you can apply as much torque as possible in a short amount of time.

The downside of high IPM is that it can cause wear and tear on the impact wrench itself, so it’s essential to choose an IPM that’s appropriate for the task at hand.

The benefits of using IPM on an impact wrench

IPM, or impact per minute, is a feature found on many impact wrenches. By measuring the amount of torque output per minute, IPM provides a more accurate measure of power than traditional torque ratings. This can be especially helpful when working with sensitive materials that can be easily damaged by too much torque.

In addition, IPM can help prevent operator fatigue by providing a more consistent power output level. As a result, impact wrenches with IPM can be an essential tool for anyone who needs to perform precision work.

How to measure impact per minute (IPM) on an impact wrench?

To correctly measure IPM on an impact wrench, you’ll need a few tools and some patience. Here’s a detailed step-by-step guide:

  1. First, you’ll need to gather a few things: an IPM chart, a measuring tape, and your impact wrench.
  2. Once you have everything you need, lay your chart out on a flat surface.
  3. Then, measure the distance from the bolt’s center to the anvil’s outside edge using the measuring tape. This is the “A” dimension.
  4. Next, gauge the distance from the bolt’s center to the socket’s center. This is the “B” dimension.
  5. Finally, measure the length from the center of the fasteners to the end of the handle. This is the “C” dimension.
  6. Once you have all three measurements, you can consult the IPM chart to determine the correct IPM setting for your wrench.

With a bit of patience and careful measurement, you can easily find the correct IPM setting for your impact wrench.

Following this guide will help ensure that your projects are completed correctly and efficiently.

Tips for getting the most out of your impact wrench and IPM

An impact wrench can make even the most stubborn fasteners loose. If not used properly, an impact wrench can cause damage to the bolts or surrounding materials. Here are some tips for getting the most out of your impact wrench:

  • Always use the proper socket for the fastener you are trying to remove. A too-small socket can strip the bolts while using one too-large can cause the socket to slip off.
  • Wear eye-protecting glass to protect your eyes from flying debris when using an impact wrench.
  • Before using the wrench, read the owner’s manual to familiarize yourself with the tool and understand how it works.
  • Keep a firm grip on the wrench handle and apply steady pressure. Do not jerk the wrench or apply too much pressure, as this can damage the bolt or surrounding materials.
  • Be careful not to overtighten fasteners with an impact wrench. This can damage the threads and make it tough to remove the fastener in the future.
  • After use, clean the tool and put it away in a safe place—Unplug from the power source.

What are the differences between IPM and RPM?

IPM and RPM are two measures of machine performance. IPM measures the number of impacts a machine can make in a minute, while RPM measures the number of rotations a machine can make in a minute. The two measures are often used interchangeably, but there are some significant differences to take into account.

For example, IPM is a more accurate measure of striking power, while RPM is a more accurate measure of cutting speed. As a result, IPM is more relevant for machines that are used for breaking or crushing materials, while RPM is more relevant for machines that are used for drilling or grinding.

When choosing a machine for a particular task, it is important to select one that has the appropriate IPM or RPM rating for the job.


Even if you don’t know exactly how IPM works, understanding that it is a feature to look for when purchasing an impact wrench can be helpful. This can result in longer tool life, improved work efficiency, and reduced operator fatigue.

By keeping this in mind, you’ll be on your way to making a more informed purchase that meets your specific needs. We hope this information will help you to make a wise judgment for your next project.
