How to replace the brushes in a Dremel 395 Type 2?

My tool does not have the access on the sides that you put a screwdriver and turn the housing to access the brushes. I can not find any information on how to remove the access pannels.

I figured it out. Use a small std slot screwdriver (not a jewelers or hobby screwdriver, more like the smallest standard screwdriver in your regular tool kit). My Type 2 Model 395 has a couple small tabs. Put the blade of the screwdriver on one of the tabs (shaft of screwdriver perpendicular to the tool) and press downward (not too hard) and toward you (if right handed). The plastic tabbed cover should rotate in towards the tool. That's the brush holder and you are rotating it 180 degrees so that the brush comes to the top. It will take a couple of "bites" of the screwdriver to rotate it fully. Be careful b/c the brush is under spring tension and if you rotate it w/o care it will shoot out (my first one did). Anyway, you should see a carbon brush with a slight arc cut in it if you have any brush left. Hopefully, you have little or no brush and a spring. Then it's easy to replace (my brushes were OK and just re-seating them and my tool was OK). Note that the 90930 brushes sold at most hardware stores won't fit. They are for the Types 3,4, and 5 model 395 (and other dremel models). You need the 90929 brushes for the Type 2. My camera is klutzy. If you can't get it, let me know and I'll try to post a picture or video.

SOURCE: My Dremel tool motor still works but shaft won't turn?

From looking at manual there is no transmission or connector so the only possible explanation is that the shaft is broken. You might try calling this number
1-800-437-3635 to see if they repair or can further advise you.

Dremel 395 Rotary tool won't turn on or won't stay on but a second or two


Electrically speaking there are a few items to check.

1) The easiest is to remove the two brush holders screws on each side by the power cord. If one of the screws are loose, or the bushes are worn you will get intermittent or no operation.

2) Second use a volt ohm meter to make sure you have voltage on the two brush connectors inside the brush holders when power is on. If you do then open the unit a check continuity on the motor armature to see if it is open, which will cost $13.37. If you do not have voltage, inspect the power cord and switch.

I was working with the dremel and it shut down and would not turn back on, the motor was not hot. I'm wondering if it has anything to do with the brushes in the side of the motor housing?


My dremel started doing that too. If I rubbed the sanding drum along a piece of wood, it would start up again. I think the brushes and the copper armature get glazed over with non conductive dust and possibly insulation smoke which disconnects it enough to stall out. Change the brushes to the new ones in the kit. After a year of heavy use mine slowwed down to about 300 rpm and then died. A very nice tool but I prefer the Makita which is about three times this size just because it is longer lived.

How to change brushes


Either side of the body are two round plastic caps with a slot in under these are a spring attached to the brush, what you need to do is unscrew the cap with a small screwdriver or the end of the collet nut spanner, and withdraw the spring and carbon brush, check the length of the brush and replace if worn down, replace the brush cap and run the tool without load for five minutes to bed the new brushes in. (if the brushes are ok make sure you replace them in the same orientation as removed).

My dremel works intermitently. As I move the switch from one speed to another it will momentarlly run. Whats the problem? THANKS


You described intermitten pwer supply, follow this procedure:

1. check your power cord for breaks or kinks, especially where it join the piece or plug
2. if cord is ok, check/replace brushes.

To check/replace brushes on dremel 395 follow this procedure:

1. switch off unit, remove power cord.
2. with flat screwdriver remove gently brush covers, WATCH FOR LITTLE SPRINGS!!!
3. check brushes for wear, springs if connect correctly, if brushes are thinner than 3.2mm (1/8") replace with new ones, this check should be carried regardless after about 50hrs of use, brushes last about 50 to 60hrs in normal use.

In unlikely case that it is switch, this is as well very easy replaceable.

1. switch off unit
2. remove cable from power source
3. remove brushes following previous procedure
4. remove collar from front of the piece
5. remove side screws and gently pry apart halves, label side up
6. replace switch
7. screw pieces back in reverse order
8. replace back brushes.

All parts are easy available, when purchase brushes or switch, be aware that they fit only particular model!

I would recommend clean table with butcher paper on top, torx/hex screwdriver, philips screwdriver, flat screwdriver - these vary from country to country, I cannot provide what exactly tools you will need, you need to check what screws are holding your piece together, little long nose pliers can be helpful as well.

As you pull handpiece apart put your parts in order in whihc you pulled them apart, when you put them back, it will be easy to put them back in reverse order in which them come apart. For changing brushes you need about 5min (assign 15min), for changing switch or faulty power cord you need about 1h (assign 3hrs), assigned time is theoretical, prctically multiply it by 3...

If you have anymore questions, or require more detailed instructions, do not hesitate to follow this thread and leave note.

Leave note how it go, thanx!

Unit wont run at all, yes I do have power, took apart and 1 of the brushes was stuck in slot and it looks like its been really hot.do I need to replace the switch assy. dremel 395 type 4,


I would think that just the brushes, they should slide freely in the slot. check also the condition of the armature for arcing or raised commutator bars.

Should I be lubricating my dremel (395) tool?


Just a comment-Based on experience, I would go with BOTH their suggestions and order brushes and bearings. That squeal is definitely the bearing; it is a sleeve bearing; RPMs too high for a ball bearing to last and the sleeve bearing has a solid lubricant cast into it.

My Dremel 395 type 4 does not run until I spin the chuck and then only runs at high speed.


Sounds like a switch or brushes. You can go to Dremel.com and they have a toll free number for their tech services and you can also download a breakdown for this tool.

How to replace brushes?


On either side of the switch is a black disk with a notch small enough for a small screwdriver. Unscrew it and take it off to expose the spring. Gently pull the spring out and the brush should be attached. If you encounter resistance, then you may disconnect the spring from the brush. If this happens then push the spring back in and hope you catch the brush; if this does not work, then get creative or take the whole thing apart to get to it. After that, just put the new brushes in and recap.
