Why is My Cordless Drill Smoking: Possible Reasons With Solutions

Why Is My Cordless Drill Smoking Possible Reasons With Solutions

To figure out the reason why your cordless drill is smoking, it is essential that you know the working mechanism of your power tool. We have listed the most common parts responsible for this problem below:

Troubleshooting Your Armatures

Motors are powered by their armatures. A drill’s armature can be damaged by overworking, resulting in the windings being burned out. The armature must be removed to be checked for damage and continuity.

A 180-degree test can be used to detect a bad armature. When you have removed the armature from the unit, place it on a bench. Measuring the resistance of the windings can be done with an ohmmeter attached to both sides of the commutator.

It does not matter what number it reads as it moves around the commutator. If all the windings are good, you should see a consistent reading. A bad armature varies wildly, reading zero or open circuit.

The reading test is another test. Bad armatures are indicated by a zero or open circuit on the ohmmeter. An ohmmeter should be placed on the tip of the shaft of the armature and the other lead on the commutator for the last test.

Solving Your Armature Issue

Removing the cover requires removing the screws that secure it to the case. Once the transmission screws on the side of the drill that connects the cover to the drill have been removed, you can remove the cover. The motor and transmission assembly must be lifted out by removing the hold-downs.

Transmission should be separated from armature and field. Make sure that the armature is free of dirt and debris by taking it out of the field. Test continuity by cleaning with thinner, drying thoroughly, and cleaning with thinner if necessary.

New arms should be installed if the old ones are bad. Assemble the armature and place it in the field. A notch will be found on the field, indicating the transmission’s front. Put it back on the transmission and reattach it.

Reinstall the motor or transmission assembly in the housing after installing one brush on the housing. Reinstall the cover on the housing after installing the second brush into the cover. Attach the end cap and the two transmission screws again.

Troubleshooting Your Battery

Smoke from a cordless drill can also be caused by the battery, specifically when the battery is being charged. The smoke is usually the result of excess heat, which can occur when the battery is defective or when it’s not being properly cooled. 

If the battery is smoking then there is internal damage somewhere.

Solving Your Battery Issue

It is not possible to repair batteries. Power drill batteries should be replaced with the ones recommended by the manufacturer.

Troubleshooting Your Carbon Brush

Drills can smoke due to carbon buildup between brushes and commutators. Carbon brushes rotate on the commutator, providing electricity to the armature. It is possible for carbon brushes to spark more as they wear down.

Solving Your Carbon Brush Issue

This can be fixed by replacing the brushes and cleaning the commutator, which will vary slightly between drills. It may be necessary to replace the motor for some cheaper models since they have sealed motors. On the drill, remove the end cap first.

The cover contains one brush. Lift the motor up and remove the other brush holder by removing the screws securing the hold-down brackets. Remove the holder from the case as well. Replacing the brushes with new ones can be done by removing them from the holder.

After removing the drill motor, separate the transmission assembly from the armature. Lightly sand or file the commutator to remove any dust particles. It is now time to reinstall the armature.

The motor and transmission should be reunited and the brush holder should be inserted back into the housing. Reinstall the cover back on the housing and tighten the cover down after the installation of a second brush holder.

Troubleshooting Your Brush Holder

In order to keep the brushes on the commutator in place, holders are used. It is quite possible that if the holders are damaged, the brush may not be able to be held in the proper place and under the correct pressure on the commutator.

It is possible that this can cause excessive sparking, resulting in the tool smoking. The brushes should be checked in both brush holders to see if they have any damage or wear, and if necessary, they should be replaced. There can be a problem if the brush holders do not sit completely in the brush holder or if they are positioned a little out of alignment, which could lead to the problem continuing.

Solving Your Brush Holder Issue

The best thing you can do for them is to clean them thoroughly if they are in good physical condition. In order to remove the holder from the housing, you will need to take off the end cap of the drill. The hold-down brackets on the motor will need to be removed by unscrewing the screws and securing them. Then take out the other brush holder from the motor by lifting it up from the motor.

Make sure that the brush holder is properly seated in the housing once you have reinstalled it by pushing it all the way in. The wire must be reattached and then the motor must be reinstalled and the brackets need to be tightened down as well. Once this has been done, reattach the wire to the second brush holder and reinstall the second brush holder in the cover.

Troubleshooting Your Commutator

One of the most common problems that can cause a cordless drill to smoke is a faulty commutator. The commutator is responsible for transferring electrical current from the battery to the motor, and if it is damaged or not working properly, smoke will begin to emit from the drill as it overheats. When the drill is used for extended periods of time, the commutator can overheat, causing it to emit a small amount of smoke.

Solving Your Commutator Issue

In order to solve the commutator issue, it is necessary to replace the faulty component with a new one. Once the new commutator is in place, it is important to test the drill to make sure that it is working properly before using it again.

Troubleshooting Your Motors

There are four main components of a motor: an armature, commutator, brushes, and a field. Any of these components could fail, resulting in the motor smoking if any of them does not function properly.

Solving Your Motors Issue

The motor must be removed from the drill in order to diagnose the problem. You can only replace the motor on some cheaper models of drills since they are sealed units.

It is easy to repair the motor of heavy-duty built drills because they can be taken apart. Remove the end cap and the screws from the cover to the housing. Make sure you use the correct transmission motor for your model and replace the one in the transmission.

Troubleshooting Your Switch

If the switch is pushed, it will provide power to the motor so that it can run. A worn switch can short out and produce smoke if it becomes so worn that it shorts out and becomes worn out.

In order to tell if a switch is failing, the drill will not work every time it is pushed, for example, it will not work when the drill button is pressed. With continued use, the condition will eventually get worse to the point that the device may begin to smoke as a result.

Solving Your Switch Issue

You will need to remove the switch from the drill in order to do this. If you find burn marks on the inside of the switch, you should replace the switch. If you see these symptoms, you will know that it has either shorted out or has completely shorted out.

Due to the fact that the switch cannot be repaired, it will have to be replaced. Replace the old switch with a new one in the housing and reconnect the wires to the brushes once you have installed the new switch.

Why Is My Drill Bit Smoking?

The smoke is rational because of a buildup of dust and debris on the drill bit. When the drill is operated, the high speeds cause the debris to heat up and release tiny amounts of fumes. If you notice that the smoke is accompanied by sparks or flames, then it’s time to stop using the drill and take it for repair.

The smoke is simply wood or concrete dust that has been heated up by the friction of the drill bit. There may be cause for concern if the drill bit starts to produce a burning smell. It is possible that the material being drilled is catching fire. In this case, it’s important to stop drilling immediately and allow the material to cool before continuing.
