To remove a cobalt ring, especially in an emergency, the recommended method is to use a diamond impregnated cutting disc.
Why Diamond is Necessary for Cobalt
Cobalt rings are known for their extreme hardness and durability, making them resistant to conventional ring cutting tools like those used for softer metals such as gold or silver. When a cobalt ring needs to be removed quickly, for instance, due to swelling, a standard metal saw or cutter typically won't be effective.
This is where a diamond impregnated cutting disc comes in. Diamond is the hardest natural substance, capable of cutting through very hard materials like cobalt with relative speed and efficiency.
The Recommended Method
Based on expert advice, the most effective way to cut through a hard cobalt ring is by utilizing a tool equipped with a diamond cutting disc.
- Tool: A high-speed rotary tool, such as a Dremel, is suitable for this task.
- Accessory: You will need a diamond impregnated cutting disc.
- Process: Attach the diamond cutting disc to the Dremel tool. Carefully and steadily apply the spinning disc to the ring, cutting through the metal.
Using this method, a cobalt ring can typically be cut off in about 5 minutes.
Sourcing the Tool
Diamond cutting discs are readily available and can often be purchased online through platforms like eBay for a few pounds, making them accessible for home use with a compatible rotary tool.
Safety Precautions
When attempting to remove a ring using power tools, safety is paramount:
- Always wear safety glasses to protect your eyes from flying debris.
- Protect the finger with a barrier (like a piece of thin metal or a popsicle stick) placed between the ring and the skin before cutting begins.
- Use a gentle, steady hand and avoid applying excessive pressure.
- Have water or another cooling liquid available to cool the ring and the disc during the cutting process, as friction generates heat.
- If possible, have someone assist you.
While this method is effective, it is generally recommended that ring removal, especially in emergency situations involving injury or severe swelling, be performed by trained professionals in a medical setting whenever possible. However, understanding the necessary tools and methods is crucial if professional help is not immediately available.
