- Always wear safety goggles to protect your eyes from flying debris.
- Use a dust mask or respirator when generating fine particles.
- Avoid loose clothing and contain long hair that could catch in the bit.
- Ensure the bit or accessory is securely inserted and tightened before use.
- Allow attachments to reach full speed before touching the workpiece.
- Apply only light pressure – don’t force the bit.
- Support the workpiece with clamps or a vise to keep hands away from the bit.
- Take care when changing accessories – allow bits to cool and stop spinning.
- Unplug Dremel when swapping bits or making any adjustments.
- Keep hands away from the nose cap area when running – grip further back.
