Milwaukee M18 Impact Driver Problems

The impact driver is pretty rigid, and with Milwaukee’s exceptional support services, you get to enjoy an overall seamless experience with the tool.

However, there are some common problems on the tool as well that you might come across while you are using this tool. A few such problems that you will need to be careful about are:

  1. Variable Speed Trigger Issues

There are lots of interactive features that you get to enjoy on the Milwaukee M18 Impact Driver, and the variable speed trigger is one such feature that allows you to control the rotational speed of the impact driver.


You can also adjust the impact power and force on the Milwaukee M18 Impact driver, and all that makes it easier for you to get the job done in the order that you like to while at the same time enjoying the perfection of having the best posture on your hand.

However, the variable speed trigger might not be working optimally at times and will not change speeds.

To fix all such problems, you will need to ensure that you are checking on all the factors that might be there, including turning off the impact driver and then turning it back on.

However, if you continue to face the problem, you will need to move forward with the diagnosis and check the speed trigger thoroughly since it might be clogged, or some wire inside that connects the motor to the trigger might have been broken.

Fixing such wires will get you rid of the problem, and you will be able to choose the speed on your Impact driver again.

  1. Not Charging

Milwaukee M18 Impact Driver is a cordless tool that adds a certain bit of liberty for you since you can use it on odd angles at the same time or having a wall outlet as all since you don’t need the additional power source for it.

That is why if the Milwaukee M18 tool is not charging, that can be problematic for you. You will need to make sure that you are checking on the charger and ensure that you are using a compatible charger that is designed to work with the tool.

After that, you also need to have the battery health inspected in order to ensure that you are not facing any such problems with the battery health that might be causing you to have issues with the charger.

  1. Too Much Noise

Next, you might feel like the Milwaukee M18 Impact Driver is creating excessive noise than usual, and that can be a problem for you to have.

Not only is the noise an issue itself, but it can be an indication of something else that might be wrong with your tool, and you need to have that fixed for sure.

That is why you will need to ensure that you are getting all such issues checked in order to ensure a better experience on the tool.

Most of the time, it is a lack of lubrication or some gunk buildup inside the tool, and cleaning it properly, followed by some machine oil, should be fixing up the problem for you.

  1. Bit Not Locking


The situation with the bit not unlocking can be just as annoying and will mostly point toward hardware issues with the driver. However, you will still need to check the accessory bits along with the chuck to isolate this issue.

If you find the issue to be more related to the bit, you will have to try out a new one.

Similarly, if you find the issue to be more related to the impact driver chuck, you will have to order a new one. There are no quick fixes that can help you get through these hardware issues.

With that said, sometimes the issue is with the placement and the adjustment of the bit in the chuck. So, you can experiment with different orientations and make sure that the shank is in place.

You can also seek some pointers from local experts, and that will save you a bit of hassle in the long run.

Similarly, some bits are just not compatible with the unit. This is especially true if you’ve bought the pack from a secondary dealer.

So, instead of blaming the unit, you need to look at the drill for possible errors. There is no point in trying to make use of an incompatible bit, and you will need official support.

There are no quick methods that can help you through this situation. If you’re still sitting on a valid warranty, we will suggest that you call up the dealer instead. There is no point in trying to make use of the unit when it seems to be damaged.

He will take a while to verify your claim and will then issue a fresh piece that you can install in your driver. From there, the issue with the bit will be fixed, and you shouldn’t try to force the bit inside of the chuck again.

Otherwise, the driver can get damaged, and you will be left with the same situation where the drill won’t stay lodged inside the chuck as you try to finish the project.

  1. LED Issues


Lastly, the issue with the LED can also be pretty hard to deal with at times. There have been countless reports from owners where they underscore errors with the unit getting damaged and the LED stays on even after the trigger is released.

Here, you need to first check the condition of the trigger and clean around it a bit as you’re trying to adjust the issue.

That will be more than enough to help you through the majority of errors. However, if the trigger is not to blame here, the next thing that you need to check is the wiring. 

There is a chance that you’re dealing with a wire shortage that is causing the LED to malfunction. You will have to order a new LED here and then install that on your driver as you try to address the situation.

Customer Support

This process can be a bit hard, and we suggest that you take your driver to the local repair center.

That will help you avoid a ton of hassle, and you will not have to wait for a replacement part. Instead, the Milwaukee-certified repair center will have an inventory of many repair parts, and you will have the new unit in no time. 

It all comes down to how you’re planning on addressing the situation. Seeking official support will make your life much easier as you try to adjust the issue with your smart units. So, be sure to keep that in mind and fix the driver LED accordingly.

Wrapping Up

Planning on upgrading the toolkit with the Milwaukee M18 impact driver? Just go through this list of common problems and fixes that you might have to deal with.

Most of the time, all of these issues are easy to fix. So, there is no need to worry about extensive routines.

Furthermore, you will be able to avoid close to ninety percent of the issues with the impact driver by being a bit more mindful of maintenance. The issue with the trigger, battery, and bit can be avoided by keeping the unit in proper storage boxes.


However, if you find that the unit was damaged out of the box, then you’re not to blame here.

Instead, you need to call up the dealer and have him send you a new unit. You can’t rely on a broken unit for long, and it will eventually give out on your projects. 

So, all that you need to do is to claim the warranty and then adjust the new impact driver.

Most of the time, it will take a few days to get a replacement. However, you can speed up the process by providing the dealer with valid proof of purchase, like a receipt.
