Impact wrenches are used for lug nut tightening and losing. When you use an impact wrench some problems can occur due to electrical and mechanical problems. An impact wrench can heat due to many problems. So let’s see what are the reason for impact wrench overheating while you using it.
An impact wrench can overheat due to many reasons. Below are the reasons and how I fixed it within a minute. So let’s check it out. In this guide, I discuss all about electric cordless impact wrenches overheating problems and quick answers you can follow.

Continuous Using
When a tool uses it generates heat. Generated heat should be removed quickly. If the generated heat is not removed quickly it can overheat. So when you work a long time you can feel the tool has overheated due to this reason. You can let the tool cool and then start the work again. Do not use any liquid or any method to cool the tool. Let it cool naturally.
Solution – Do not use impact wrench continuously. Let it cool when you feel it is heating up

Applying Maximum Loading
Impact wrenches have three types of torque generations.
Optimal torque – Best productivity torque
Working torque – Maximum working torque
Maximum torque – Maximum torque that tool can produce
When an impact wrench is working under the maximum torque it needs to produce maximum power. So tool can overheat in this range. Do not work in this range much time.
Solution – Do not work on maximum torque. Work on the working torque as much as possible.
No Lubricants
Lubricants can do two main things. It can transfer the heat and it can reduce friction. when the surfaces are touching each other heat can be rise. Due to this reason, lubricants do amazing tasks. So if there is no lubricant surface will heat due to friction and then it will overheat. So use recommended lubricant after a regular period.
Solution – Apply the lubricants when you serve them. At least service once a month if you use it regularly.
Carbon Brush Worn Out
Impact wrenches consist of brushed motors or brushless motors. The brush touches the commutator while it is rotating. It produces heat due to friction. As a result of this brushes can wear. When a brush is worn it is unable to touch the commutator properly.
So commutator brushes heat due to friction. When this is happening continuously it’s heating up.
solution – Remove the brush when it reaches the length 1/4 of the original length
Ventilations Covering
Ventilation is really important. It can transfer the heat as hot air. If the ventilation is blocked and hot air is not able to transfer properly. So inner heat can be increased due to ventilation coverings. Sometimes ventilation covering with the hand when we use it as well as it can clog with the dust also.
Solution – Use your hand properly as it does not cover the ventilation. Clean the holes when you serve them.
Use in a Sunny Area
When the tool is used in the high heat area its temperature can be increased. some time sunny area is too much hot. it consists of much heat. if you use the tool under this area its heat will not be removed easily. So its heat can be risen and then overheating.
Solution – Work under low heat area.
Battery Use in the Wrong Tool
Sometimes we try to use the battery in the wrong tool for our mistake. If we use the 12V battery in the 18V tool, the battery will overheat due to high power consumption. So make sure to use the correct too and correct battery.
Solution – Use the recommended battery. Do not use any adaptor to connect other types of batteries. it will damage both

Electric Shorts
Due to some reasons inner coils, wires, circuits can be damaged and electricity can be leaked. So it can heat up. You can observe this by battery losing power quickly than a regular time period.
Solution – Remove parts and check which has been damaged and insulate them. Else remove it.
Bearing Problem
Bearings are used for supporting the free end rotating. If there is a problem with the bearings, they can heat while it is rotating. So make sure the bearings are working properly in your monthly service term.
Solution – Check and lubricant the bearings while you service the impact wrench.
