Step by step guide to removing and replacing a Dremel bit

Here’s how to replace a Dremel bit:
Step 1: Press and hold down the lock button. This is located near the top of the tool.
Step 2: Use the given wrench tool to loosen the chuck until you are able to take off the accessory.
Step 3: Remove the used accessory. If necessary, change the collet nut to the corresponding size of the Dremel bit.
Step 4: Take the new bit and insert it into the collet nut while holding down the lock button.
Step 5: Use the wrench tool to tighten the loosened chuck to secure the collet nut and the accessory bit.
What to do when the Dremel bit gets stuck?
In the case when the replacing bit is stuck, the first thing you need to do is to loosen the bit until it has at least some room to maneuver.
Try apply some clean silicon spray. If this fails after applying some lubrication, heat up the collet with any available heat source for at least 10 seconds.
The heat will expand the metal and may loosen it, wait for the bit to cool down then try unscrewing it again.
If somehow the Dremel bit still appears to be stuck, an alternative is to spray some stronger penetrating oil such as WD-40 to loosen the bit, then allow it to rest for approximately 5-7 minutes.
After all of this is done, use any tool that has a strong grip then attempt to pull the bit out.

Another solution is you can make use of a threaded nose, this attachment can make some bits compatible with a rotary tool with a different collet size.
How to attach a drill bit to a Dremel?
Dremel bits can be used on a regular drill, but this does not mean that you can use most drill bits in a Dremel.
To attach a drill bit to a Dremel, you can make use of the 4486 Dremel chuck, this is smaller and works like a chuck on a drill that creates a wider opening and a tighter closing.
This accepts regular drill bits in the shank size ranging from 1/32 inch to 1/8 inch. A drill press attachment is another idea also.
