Fixya show me how to assemble tool to use smallest drill bit dremel 3000

The flashing light indicates an error, possibly your battery is shot or malfunctioning. New battery needed.

You can use a drill that fits directly ( one size) or you can use a small chuck made for the Dremel. example: http://www.homedepot.com/p/Dremel-1-32-in-Multi-Pro-Tool-Chuck-4486/100531881

For a tool like the dremel you push down the shaft lock button on the side of the bit and use the small wrench to unthread the collet nut.
basic manual, others on page: http://mdm.boschwebservices.com/files/05-11%20100-3000%20r37449v3.pdf

Try clamping channel lock pliers on the bit. Tap pliers with hammer to dislodge.

Go to Amazon and do a search for "dremel drill chucks". There are a variety of models that will close down to '0' to allow use of bits as small as #80. Make sure and look at the low end capacity and make sure it will go small enough for the size bit you want to use. I have used to #4486 to use micro drill bits but it is not rated to go that small and can cause wobble and break the bit if not very careful. They are pretty cheap so you can try a couple different models even.

try installing a new set of brushes in it i have fixed mine lots of times by doing just this !!! new brushes are sold where ever real dremel tools and bits are sold ck package back for your model number

The button is only to keep the shaft from turning while you loosen the collet (the nut) with the little wrench. THEN the tool comes out.

You may have to change mandrel to a smaller one. There should be 2,if not 3, in your kit. I ended up buying the 4486 keyless chuck to save time on tool changes.

I hope this helps. M

possible if you have a drill bit smaller than the screw and you can try drilling in reverse. Might be better just to replace the mandrel though.

you should have a little wrench that came with it

and on the neck of the dremel there is a shaft stop button

push the button and manually rotate the dremel head till

it clicks then hold the button and use the wrench to loosen the bit
