It is easy, you may find first time that it will not be so, but if you follow advice, it will become even more easy.

1. switch off motor
2. unplug from power
3. find button on the base close to rotating bit, press and hold, this is shaft lock which if applied correctly (you may need to rotate shaft a bit till it fully engage) will stop shaft from rotating
4. apply small spanner (provided with set) to collet collar (collet have two indentations fitting perfectly little spanner)
5. if shaft is held up, turn spanner anticlockwise, then use your hand to undo collar completely
6. remove collet and bit - separate bit from collet
7. collet comes in many sizes, select correct size for new bit
8. insert collet into throat
9. lightly screw in collar
10, insert new bit, at least 2/3 of the bit shank must be inserted into the collet!
11. held shaft lock button pressed
12 hand tighten the collar till bit is locked firmly in place
13. do not use spanner to tighten! if collar do not held properly, re-tighten by hand only!
14. wear always glasses when operating dremmel, or any other rotating machinery, it is not a toy! and exploding bit will penetrate not only your bit of woo, or metal but your eye as well... and your have only two and no spares...

if you find my advice useful, please do not hesitate to vote4 for me, or leave comment, or both... thanx!

You can change to any bit, but have to change the compression collar inside the end of the shaft. For example if the tool shaft size is 1/8" you need to use the 1/8" collar etc. Make sure you use the corresponding bit with the corresponding compression shaft size or the bit will not lock in position when you tighten the collar.

Dremel 3100 won't release the drill bit. Button at the top is pressed in and won't come out.

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.

Push the pin on the side next to the tip and hold it while Your wrench is turning the hex shaped piece around the bit that is what is holding your bit in. this should help as i am a proud owner of a Dremel. Hope this helps . if you have any further questions write back.
