Why has my dremel 6000 just stopped working could it be the brushes

No.. the issue issue is the switch inside. when your Dremel 4200 stop working, press firmly the grey area between the speed selector and the brush housing. I think this a defect in the design of the 4200.

www.supergrit.com has the sanding tubes for the Dremel 6000 in stock

Most likely you will find them on EBAY---search there for Dremel.

Mine died also. It's the on off switch. Where can I get parts?

If you have a volt/ohms meter It is a process of elimination. First unplug tool and remove the brushes turn the switch on and check for continuity to the brush holders and if none work backwards start with the cord and then the switch etc until the problem is found.

Hi it sounds like you have a brush worn out. I would change out the brushes first and go from there. Brushes are relatively cheap and it is a good investment to check out first. You can get brushes from almost any hardware store that sells Dremel parts and accessories.

Most of our issues with Dremel tools is with the plastic brush holder. If the tool is used for exetnded periods of time or 'leaned' on too much the holder will get hot enough melt and keep the brushes from contacting the armature properly. Try taking your brushes out, if they don't slide in and out of the holder freely you may need to file or cut away any plastic that is holding the brushes off the armature. This may require you taking the brush holder out so you don't damage the armature. Be careful with the brush holder, it is not available as a replacement part.

On a 4000 there is a thermal fuse at the base of the motor from the brush housing. They are cheap to replace. these are replacing fuses on alot of electronic devices. the fuse is a microtemp g7f01 110c.

It could be the fuse between the brush and variable speed control switch. I have the same problem and found the fuse blown. I am hoping that I can replace the fuse without having to buy the complete speed control unit which is about $17.00 from Dremel. If yours is still under warranty you could send it back. If I can find a fuse for mine I will let you know where to get them. joatmontag

When the brushes go on my Dremel, it just stops, sometimes erratically - no smell or burning.
