Well i use to rely on makita and Campbell Hausefield and because I used them a lot - I always had a set on hand - I as a general rule would not run them below 75% wear- go to their web sit and check - be advised that as the armature wears- you will get less mileage from brushes. Best of luck. Oh replace them is you are in doubt-this willprevent bunrout on armature

I was using the drill and it just stepped the light comes on but the drill don't . what can it be

Most cases there are worn brushes replace the carbon brushes but only if your machine sounds smooth , otherway replace also the armature , if you are thinking that your capacity of the battery was short , then it can be a positive experience because you get longer can work with one battery charge and have more power because of the price the armature is much cheaper then a battery and also the brushes can if there is a thermical shorting inside the armature a lifetime of 4 weeks when you replace a brush on a bad armature .

I have a B&D drill 7190. One of the brushes has a black which has broken from somewhere? I do not see any place to reconnect it.

The field of the motor is on one site not in balance( measured in Ohms compare this between the 2 fields let you see a little or great difference for shure) REPLACE THE electric field when you can find that part anywhere ?? in this case because the carbon brushes must be both have the same length will the tool in good condition . B&D when replace the brushes it will be in a short time the same problem and 7190 the vital parts are not new delivered anymore.

Sparking from the rear air vents during use--cause and how to fix

The most likely cause is the carbon brushes that make contact with the armature are badly worn. There should bea circular port on either side of the housing near the rear. They look as if a coin would be the right shape to unscrew them.when removed you should see a spring and a carbon block on the end. There will be a severe concave gouge at the end. Perhaps almost no block at all. It is simple to replace then bushes, simply slip in the new ones and align the spring to the cover and screw back on.
Take note that the bushes may so badly worn that they will fall apart when removed.
Get new "carbon bushes"for that model drill before disassembly, they are not expensive, look on ebay. If this is not the problem the chances are It is a faulty armature, in which case by a new drill, happy fixing.

Need carbon brushes for makita mod#m601 10mm drill

I could only find a 601D which is a cordless drill with a sealed motor so you can't just replace the brushes and the motor is discontinued.

Drill does not work when i press the trigger

Did you take a look at the carbon brushes?. Metabo has what they call Auto stop Carbon brushes. so if they are worn down they will pop away from the motor and the drill will simply not run. this happens when the brushes are basically worn out.

HI, My neighbours are complaining about the interference my drill is causing to their tv, radio etc. What is causing the problem and how do I combat it?

check the power cable of the drill is it a 2 prong or 3 prong plug? if it's a 2 prong it is an insulated power tool it is prone to emitt EMI (Electro Magnetic Interferance) becaus the casing is usually plastic, what could be done is check the carbon brushes inside the drill they could be worn and produce a lot of blue sparks, replace the brushes, if it's a 3 prong check for a faulty ground, with a faulty ground the metal casing of the drill is not shealding the EMI and could be deadly for the user in the event of a faulty live wire touching the casing

If all is well for the drill, contact a qualified electrician and ask for a EMI filter you could ave installed in the electric panel

Good luck!

The drill was smoking while in use at the rear of the drill

Hi, these units tend to heat up over extended use. It is possible that your brushes have worn down and need to be replaced. The contact area around the commutator, (where the brushes push against), should be cleaned gently with ultra fine steel wool. Also, the gaps between the contact points of the commutator should be free of any conductive dust left behind by your dying brushes. Since the drill needs to be disassembled in order to do this, check any connections for weakness and any more conductive dust that may be shorting something. good luck.

Replacing carbon brushes of csb 500 re bosch drill

bosch brushes are unique. they have a spring embedded in the carbon so when the length gets too short, the spring lets go and raises the brush above the commutator and the appliance stops. you need to remove the handle partially or the brush covers and unscrew the brush holder(s) two small screws secure the brushes and holder to the appliance.

2 Milwaukee 18VDrills stopped working - NEED repair help

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.
