Creating a Bit Extractor
If you don’t have a dedicated bit extractor, you can create one from a few simple materials:
1. Gather Your Materials:
- A small block of wood
- A nail
- A hammer
- A screwdriver
2. Drill a Hole in the Wood:
Use a drill to create a hole in the center of the wood block, slightly larger than the diameter of the bit you need to remove.
3. Insert the Nail:
Hammer the nail into the hole, with the tip protruding out the opposite side of the wood block.
4. Secure the Dremel:
Use the screwdriver to tighten the Dremel into the hole in the wood block, ensuring the nail is aligned with the bit you need to remove.
5. Extract the Bit:
Gently tap the nail from the opposite side of the wood block using a hammer. As you do so, the nail will push against the bit and force it out of the Dremel chuck. **Note:** If the bit is stuck tightly, you may need to tap it several times or apply more force.
