Impact wrenches and impact tools are very commonly used in mechanical tools. They are widely used in industrial manufacturing and maintenance, but there are some differences between an impact wrench and an impact tool. This article will detail advantages, disadvantages and applicable cases of these two tools to help you understand differences between these two tools so that you can better choose tool that suits you.
First, let's imagine an impact wrench. An impact wrench is a torque tool driven by a pneumatic or electric motor, principle of which is to use a high-speed rotating hammer to transfer impact force to wrench, thereby increasing torque of wrench. Impact wrenches are typically used to tighten bolts, nuts, etc. where high torque is required for threaded connections.
Impact wrenches are easy to use, high torque and high efficiency, but they also have disadvantages such as loud noise, wear and high maintenance costs.
Impact wrenches and nutrunners have some similarities, but have different designs. The impact tool is driven by a pneumatic or electric motor. The principle is to use a high-speed rotating hammer head to transfer impact force to tool to loosen or tighten screw. Impact screwdrivers are often used to remove or install screws, such as when servicing cars or machines.
Compared to impact wrenches, impact wrenches can be used over a wider range, but torque is not as high as impact wrenches. The advantages of an impact driver are that it is easy to use, less prone to wear and tear and low cost, but it also has disadvantage of being loud.
In terms of usability, an impact wrench is more suitable for tightening bolts and nuts that require high torque, such as in construction, aviation, railway transport and other fields. The impact screwdriver is more suitable for removing screws that require high rotation speed, such as mechanical equipment maintenance, car repair and other fields.
When choosing an impact wrench and an impact wrench should be selected according to specific use cases and needs. If you need to tighten bolts with high torque, you should choose an impact wrench; if you need to remove screws, you must choose an impact wrench.
