How To Choose Impact Wrench
5+1 Tips from our Techno-Experts
An Impact wrench is a valuable tool when it comes to tasks that require extra force. Designed to provide high-torque output with minimum effort by the user, an Impact Wrench is a worthy investment for every professional or DIYer.
When evaluating an impact wrench, keep in mind that the nature of the tasks is a critical factor. Although a DIY automotive project has different requirements than a product assembly line, there are typical features that should be appraised.
Here is 5+1 Tips to Choose the Right Impact Wrench
This is a very important feature since it indicates how strong your impact wrench is.
A High Torque Level ensures that your impact wrench can deal with any challenge.
To understand better the significance of the torque, lets simplify and imagine we want to tighten a nut with a manual wrench. The shorter our wrench is the more strength is need in order to tighten the nut. That is because the shorter the manual wrench the less lever it has and the less torque it can deliver
For an impact wrench, the torque is the outcome of a mechanism that produce strong blows.
The torque level you need depends on the nature of tasks you want to perform.
For heavy duties that require excessive torque we suggest a pneumatic impact wrench because it can provide higher torque levels than an electrical impact wrench.
RPM or rotations per minute is an indicator of the rotation speed of your tool.
The higher the RPM, the higher the momentum of the moving part of your impact wrench. That momentum is transferred to the fastened part as torque.
Subsequently, higher rpm will provide you with some extra torque than the stated one. But for more delicate jobs you want to be able to reduce the speed to a very low level.
Tip No3 sounds common sense but is one of the most frequent mistakes people do when they buy an impact wrench.
Choosing the proper size of square drive is an important factor of the life expectancy of your tool. The nature of the tasks you want to perform will determine whether you need a ½ " , ¾" or 1" square drive or even higher for very specific heavy jobs.
An electric impact wrench offers different characteristics than a pneumatic impact wrench. An electric impact wrench is often used for smaller bolts, the square drive is normally ½”. Its is available in a cable and battery version although the battery version is the most widely used because it is so easy to use.
Pneumatic impact wrenches are mainly used for continuous work and for heavier jobs.
Do you know which square drive covers your needs? It is time to choose your socket set for your impact wrench.
Be careful! Not all sockets are compatible with electrical tools. The socket set you will choose, must be designed for impact tools.
To begin with, you have to ensure that you know how to find the right size. And although it sounds easy, there is a trap. Nowadays not all the sockets’ measurements are in inches. The drive size is different than the socket size and has to do with the compatibility of the sockets with drive of the impact wrench. In case you change from a different size driver impact wrench to another, you can use an adaptor to adjust your old sockets with your new impact wrench.
The depth of the sockets varies and depends on the purpose of use. Usually, if you do not know what is the depth you need, is advised to go for a deeper one. However, shallow sockets are also needed in tricky narrow spaces that you will not be able to use the deep ones.
Last but not least, you have to choose the point of the socket set. Once again, that depends on the nature of the tasks you want to perform. For DIYers the 12-point sockets are suggested being built for easier alignment. One the other hand, heavy duty professionals maybe would prefer the sturdy 6-point sockets that can provide severe torque
That is a parameter that most of the buyers forget about. Impact wrenches, especially the professional ones, produce immense sound and vibration that can cause considerable damage to your ears, hands, wrist & elbows.
Therefore, among the right impact wrench and durable socket set, DON’T overlook ear defenders, anti-vibration gloves and safety goggles. If you are working in a dusty environment a face respirator will also be needed.
