How do i change the brushes in my drill

Hello Beverly, I would check for worn out brushes.

needs brush cleaning when the brushes in the motor get a little dirty they tend to work intermittently

10th March 2013. I experienced the same problem with my Bosch drill. Yes, it also only worked when held in the vertical position. I pulled the drill apart. In my case, the problem was right at the base of the drill where the electrical cord and the drill meet. In that area, there is a flat piece of hard plastic which holds the cord securely in place. This is held down by two screws. Directly beside that is the rubber attachment that hold the drill chuck. Well, right in that spot, there was a gaping hole in the wiring (refer attached photo). It will not be seen, unless you, or a service agent, pull that area apart. Anyway, I shortened the cord, secured the wiring again, and the drill works perfectly. Good luck. Ted.

Put a meter on the two wires that come from the switch to the brush holders, if there is no voltage then it is the switch. If there is voltage then make sure the new brushes are not stuck in their holders.

Sounds to me that the brushes have worn down so far that they are not contacting the armature any longer. time to pick up a new set of brushes

ya in the trigger and also could be the brushes tap on it a little bit while holding down the trigger and if it tries to run ten id say the brushes are bad

Sounds like a shorted Armature, best solution is to replace it.
Good Luck,
Gil

Sounds like a burned out motor.

Sometimes you can replace the brushes and make them work again.

When operating that drill, make sure that you are not overheating the motor.

Depending on the material that you are drilling, you may need to use the drill on a slower speed in order to not overheat the motor.

Another way is to have more than one drill, and switch to a cool one as soon as you notice heat on the in-use drill.

If your drill is battery powered, stop using the drill and change the battery as soon as the battery dies enough to slow the speed of the drill.

Operating the drill under reduced power is very hard on the motor for several reasons.

These tear the brushes out. You can not use them for hammering. It is a design problem.

Replace the brushes and use only for straight drilling.

This may not be as easy as you think. The first one my have trouble with the trigger switch, but it could be the motor. Without checking continuity, or replacing them individually you will not be able to tell which one is bad.

Another problem could be the brushes. That is what is most likely wrong with the 2nd one. Remove the 2 black screw caps on the rear of the drill, and remove the carbon brushes. Do they look worn? If so they will need to be replaced. If this is the case the motor may be breaking down, and wearing the brushes down too fast.

The good news is that Milwaukee Tools, offer a 5 year limited warranty, If you have a receipt, or can read the serial number. Take it in, or mail it to a service center. They will take care of it for you if they are less then 5 years old.
